Recipe: How to make cannabis cooking oil

September 19, 2013


Are you interested in medicating with edibles but don’t know where to begin? Infusion is often the most challenging part of cooking with cannabis and the reason why many people turn to their vaporizer in defeat. I’m here to tell you that you can do this! Not only is it doable, but it’s worth it.

If you haven’t yet discovered the wonder that is cannabis-infused eating, I’m excited for you because you’re in for an adventure. The experience from start to finish is significantly different from the other common inhalation methods. The effects are typically longer, stronger, and slower to set in. For this reason, always start with a low dose and see how an edible affects you — especially if you’re cooking your own as it is impossible to calculate their potency.

Cannabis-infused oil is probably the most versatile medium and a great place to start, since it can be used for baking desserts, sautéing veggies, frying up your morning eggs, or in your salad dressing. In addition, as is the case with cooking anything at home, you have complete control over its preparation. Does peanut oil hold a special place in your heart? Make cannabis-infused peanut oil!


Avoid these 7 common mistakes while cooking cannabis edibles

Recipe for Cannabis Cooking Oil


  • 1 cup of ground cannabis flower (or less for milder potency)
  • 1 cup of cooking oil of your choice

Note: Coconut and olive oil are the most common choices; coconut oil has a milder taste and can therefore be used for more dishes, whereas olive oil is the staple cooking oil for most kitchens. 


  • Strainer or cheesecloth
  • Grinder (a simple hand grinder works best; appliances like blenders and coffee grinder pulverize the cannabis, resulting in edibles with bad tasting plant material)
  • Double-boiler, slow cooker, saucepan, etc.


  1. Grind the cannabis. You can include the entire plant, just the flower, a little bit of both — this is all a matter of preference. Just keep in mind that anything small enough to fit through the strainer will end up in your finished product, so again, do not grind your cannabis to a fine powder.
  2. Combine oil and cannabis in your double-boiler or slow cooker, and heat the two together on low or warm for a few hours. This allows for decarboxylation (activation of THC) without scorching (which destroys the active ingredients). Cooking can be done a variety of ways: in a slow cooker on low for 4-6 hours, stirring occasionally; in a double-boiler on low for at least 6 hours (8 is better), stirring occasionally; or in a simple saucepan on low for at least three hours, stirring frequently (a saucepan is most susceptible to scorching). In all cases, a small amount of water can be added to the mixture to help avoid burning. Note: whatever method you choose, temperature of the oil should not exceed 245°F.
  3. Strain and store the oil. Do not squeeze the cheesecloth; this will simply add more chlorophyll to your oil. All remaining plant material can be discarded or used in other dishes if you have the wherewithal. The oil’s shelf life is at least two months, and can be extended with refrigeration.

Note: Be cautious when using the oil to prepare dishes that require heating. Do not microwave and choose low heat whenever possible.

    Can I do this with just regular weed I would buy

    • Jared Fleshren

      What else is there lol?

    • Abbott Fletcher

      Got a spare closet? But some lights. 🙂

      • Hugh, you seriously do NOT know what you’re talking about. Anyone who listens to you is a complete idiot,.

  • Hugh G. Cock

    Best advice? Don’t ruin food with weed. Eat some cannabutter on a cracker, with some peanut butter if you’re a wimp, then eat your food without the a** taste of weed. And the advice about getting the food too hot is complete nonsense. You smoke weed, vape it, at temperatures far higher than recommended here, and guess what? You get high. Want some oil or butter in 30-40 minutes? As a starter batch, melt 2 sticks of unsalted butter, and add a 1/4 ounce of ground up bud. Cook it medium to medium low, watching for foaming. When it starts foaming, turn it down a bit, and keep taking it off the heat. Once you have the butter at simmer, all the moisture in the weed will bubble out. Once the weed quits foaming, you’re done. Use a strainer to get it into a heat resistant container, and don’t burn your fool self. Let it cool, then put it in the fridge to solidify. Once it’s hardened you can put in a baggie or container so your fridge doesn’t stink like cannabutter. Once you get practiced up, it’s a cinch. No sense jacking around for hours on end when you can get ‘er done in less than an hour. Good luck, and DON’T BURN YOURSELF! And when you test it, go easy, and wait at least 3 hours to make sure you don’t eat too much and make yourself miserable.

    • Ted Lersch

      Is there a way to prep the cannabis for basically any type of cooking, be it candy, cookies, an oil, or butter as you described.
      Is there a way to prep the cannabis for use as a salt & pepper type thing, seasoning the things you eat, or would you be wasting too much cannabis, or maybe not use as much???
      Can the cannabis after being ground, be spread out on a cookie sheet, to be baked to get the THC, and if so, at what temp and for how long?
      When grinding the cannabis, is it to be ground to a fine powder, (as I was talking for salt and pepper type uses} or should it have some substance to it, to hold the THC?
      I am 65, been smoking pot since the age of 14. It now makes me cough too much, so the wife was talking about making brownies or something, but as you know, decent pot isn’t cheap, so I want to make the best, longer last thing we can, so as not to waste.
      Thanks, I appreciate any help you can be.

      • Hugh G. Cock

        Frankly either making the butter the way I described it, or making it the boiling water method is easiest. Making tinctures and oils is a pain, and taste like complete crap. Don’t put raw pot in food as it won’t carboxylate, which is the heating process to make the thc become available to your body. That’s why making butter or oils is the best way to ingest it. You can use it just like you would butter, you can make candy from it, or brownies, or whatever, but why go to all that trouble to have pot tasting candy and food? I don’t find it unpleasant by itself, but I would in my eggs, or pizza, or whatever. I too have COPD issues (61), so I eat butter instead of smoking. The difficult part about making butter is depending on where you are, weed can be really expensive. If you make it the way I described above, just make sure it isn’t getting too hot. If it starts foaming too much, take it off the heat for a bit, turn the heat down a little, and put it back on. You want somewhere between medium to medium low heat depending on your stove. I don’t think this is the answer you’re looking for, but this is what I know. If you want the boiling water method I’ll post it for you. It’s more time consuming, but probably safer since you have no prior experience making butter directly on heat. I used to be a chef, so it’s like making Hollandaise sauce without a double broiler. I’m just used to doing it this way. And one more word of caution, it makes your house stink, really, really stink. So keep the windows closed and don’t have the grandkids over for a day or two 😉

        • Ms Aransevia

          Hugh! I am so glad to have found you! I have been smoking herb for 37 yrs but am asthmatic and recently my lungs got so bad I HAD to give it up! After my lungs improved I researched how to make oil with herb but some of the instructions make no sense to me – wash the herb, dry it (or put it in a dehydrator?), wash it again, then roast it: all before cooking it with oil, in a special contraption, for 18hrs??? I consider myself a quick study & good cook so I combined a bunch of methods, took advice from some of the comments, simplified it & tried the following: I cleaned it (I buy it on the stalk with seeds in, leaves removed); chopped it in a coffee grinder – just like I would before rolling, fine but not powdery – roasted it on a cookie sheet in my oven at 250 for 1hr; put it in a glass bowl with coconut oil at a 1:2 herb to oil ratio; returned it to the oven & continued heating it at 250 for 2hrs. After it cooled I strained it using cheese cloth & used some in baking, some on crackers, some mixed with peanut butter. I found it best in the baking. I am currently living in the Caribbean and – after years of searching – finally found a grower/seller who provides me with very good quality herb at a great price (VERY hard for a non local to get). Pure coconut oil (commercial, not organic) is a helluva lot cheaper than butter here and I am on a tight budget so I am happy with this this combination/method. Also, the amount of herb that I would have smoked in 1 day made enough baked goods to last me 10 days!!! SO MY QUESTION, after all that (LOL) is, do you think I need to roast the herb before putting it in the oil? The above recipe doesn’t call for it but it does call for much more cooking time of the oil – and doesn’t mention oven heating, which I find easy. Alternatively, do you think I could cut the oil heating down to 1hr? I know absolutely nothing about science and I would like to make the process as efficient as possible. I guess it would be easiest to chop the herb, stalk seeds & all, but how would that affect the taste & potency? With my described method there was almost no smell when it was roasting alone or being heated with the oil, and no herb taste in the baked goods. And another thing: back in Canada a guy I used to buy herb cookies from told me to eat something small (like a 2nd, non-herb cookie) 15-20 minutes after ingesting as it would jump-start the high. I find this to be true but am wondering if it just works because I believe it will? Do you know anything about that? Lastly, I found that my baked goods didn’t fully kick in for 45mins – 1hr but the high lasted 4 – 6hrs. Thanks so much for any input you may have! 🙂

          • Abbott Fletcher

            I’ve smoked for 50 years and I have discovered that including the seeds and stems leads to bad taste and headaches. I would presume that including them in any oil concoction would have the same bad side affects. For myself, I will carefully manicure any weed before I use it in any way. A little great stuff (buds without seeds) is better than a bunch of nasty tasting all-inclusive smoke. IMHO

          • Ms Aransevia

            thanks for your response. and do you have any comments on using roasted/baked vs green herb during the oil infusion process? or any thoughts on the times?

          • Abbott Fletcher

            This is my first batch. I used 1oz manicured ground cured bud in 1lb of butter. I put both in a slow cooker plus a cup of water. I set the cooker to the lowest temp for the longest time. Next day, I poured the butter & bud (water evaporated) through a tea strainer into a pyrex measuring cup. I had no cheesecloth and I suspect I’ll want to strain the cannabutter again before I put it in (Cook’s Illustrated Classic) Brownies. We will make the brownies next week. Wish us well.

          • Hugh G. Cock

            Sorry it took so long to get back to you. You can skip the baking sheet, you don’t need to do that. Take out the seeds and stems first too, because they’ll make it taste bad. You could probably leave it in the oven at 225 for about 3 hours and that would work. That would help more of the resin to leach out into the coconut oil.

          • Gwen

            Hugh, you seriously do NOT know what you’re talking about. Anyone who listens to you is a complete idiot,.

          • M Lohnes

            Gwen, will you please shut your damn face? Every time you post a comment on here, it’s negative, contributes nothing other than your ignorance, and is usually replied back to, with an explanation of you being a ****ing moron. You have no place here, and we’d all be better off without you.

          • Gwen

            Then why haven’t you blocked me yet? You must yearn for my approval. Here it is: you’re a moron, too.

          • Gwen

            Oh, and in case you don’t get it: I already blocked you, so don’t bother to reply.

          • sonneofmanisrael

            He speaks of his experience. And he is helpful. You only troll and insult. That’s mean spirited and sterile.

          • Gwen

            No, he dosn’t. And no, he’s not. That’s my point, you idiot. How can you be so dumb you still believe the person who’s incorrect? Learn how to use the internet for finding knowledge instead of polluting it with misinformation.

          • Dianna Donnelly

            Yes. I have read from Dr. Bruce Hornsby that many edibles tested show a lot of THCA .. meaning the decarb wasn’t done long enough or high enough. THC vaporizes at about 347*F so many recipes call for decarbing temps as high as 300*F.

            It requires higher heat to decarb when in the oil which can risk losing some other active compounds so many do a dry decarb first.

      • Val

        on the coughing, get some mullein. can find in the wild by the side of the road. dry the leaves, and hand rub to crush. make a tea with it, be sure to strain it. the fuzz of the leaf may cause throat irritation. or you can smoke it.

        • Ted Lersch

          Thanks for the info you don’t happen to live in Sun City Center do you??? Please give More info on yourself and the cooking of thc. Thanks, Ted

          • Val

            I make herbal oils for lotions etc, massage oils. I use a Mason jar, or Ball Jar to heat the oil. They are tempered and won’t crack. The direction here are pretty accurate. The slow cooker method is probably the easiest.,. less over heating and doesn’t need watching over every hour. you have to experiment. The butter is easy, but again, you have to decarbolize and stand over so it doesn’t burn. I just prefer to roll and smoke. I am also in my 60’s and have been smoking since I was 14. My dad moved the family to MIami in 68. It was one big party every day. Hard not to be caught up in other drugs that were everywhere.
            If you smoke cigarettes too, you should definitely get some Mullein or Colts foot herb. I found the mother load last spring. It is limited usage to 6 weeks per year. Google both.great for lung issues, and will help with congestion, coughing and wheezing, shortness of breath.
            If you are on FB, these are many pages on herbs, wild crafting and identifying wild plants that hold medicinal properties.
            I am in near Woodstock NY. in Kingston. great area, Hudson River, Catskill Mountians and 4 nice seasons. Good food, water, and small towns are getting a boost from NYC residents moving here . Town of 27,000 is historical, and we can get thru town in 5 minutes, not much traffic, good schools. I left FL after Andrew in 97. Once was enough.
            Good luck with the processing. If you eat, wait a few hours before you re-dose. It takes some time to get thru the system. always have straight munchies on hand.

      • Hundsquat Forever

        Check out ethanol (everclear) extraction methods. Its pretty much a green dragon, then at a low temp (110 or so) evaporate all the alcohol left. I usually keep the tincture heated till oil is pretty much the only thing left. Use that oil in anything and dont bake over 350. It is already activated and decarbed if you decarbed before adding the cannabis to the everclear, so it doesnt need high temperatures again in order to feel the effects. Eating this oil raw works.

      • Dianna Donnelly

        Just decarb and store for future use. Great idea. You can sprinkle it on anything now!

    • Gabriela Espinoza

      You obviously don’t know chemistry because the temp when cooking the weed is crucial. If it’s too hot the THC will vaporize and escape into the atmosphere!!!! A vaporizer/pipe is a vessel that helps the THC get into your lungs.

      • Hugh G. Cock

        Oh, but I do. I’ve been making it for about 40 years. It just has to be hot enough to cause carboxylation (178+F), and it’s crucial not to burn the butter. You can do it with water and butter, but still, that only takes about 75 minutes tops. I’m doing it in straight butter because like cooks who make Hollandaise sauce on the heat, it’s because I’m good at it. What a vape has to do with any of this is beyond me. Keep vaping, and you’ll have COPD, chronic bronchitis, and any number of lung issues, because contrary to your hipster beliefs system that is completely wrong, vaping is bad for you. When you’ve done this as long as I have, then get back to me.

        • tony gambino

          wash the butter and you wont have that nasty weed taste buddy…just LOL at butter on a cracker

          • Hugh G. Cock

            I do. I rinse the underside of it if I make a big batch with the water method, which is why you use unsalted butter. I just like butter and peanut butter together. It doesn’t taste nasty at all, it’s just a preference.

          • Lucas

            I’ve found that doing a dry ice resin gland extraction on my plant matter gives me all of the great benefits I’m seeking with zero flavor of cannabis in my edibles. You can cook it into whatever oil you choose, I prefer coconut for it saturated fat which attaches to the CBDs best, and the entire process takes about the same 75 minutes, start to finish. Theonly addition is the 2# of dry ice (~$4) per 1/8-1/4# of trimmed plant matter.

          • Hugh G. Cock

            The dry ice method is great, but I don’t want to waste the resin that’s in the plant matter. Me and a couple of other old guys are the only ones eating it, so we don’t care about it tasting like weed. We just care about not having as many aches and pains, and putting a smile on our faces without resorting to alcohol.

          • Catherine-Pepsi Entzminger

            How much butter does that quick recipe yield?

          • Hugh G. Cock

            It’s 2 sticks, so 8 ounces, a little less because some of it isn’t going to come off the weed. Try about 2-3 grams initially and work up or down from there. If it’s not strong enough, throw more weed in it next time. You can also run it through again with more weed to make it stronger. I did it once 3 times, using altogether about an ounce of weed, and a gram of it made my wife and I hallucinate so hard we had to take a cab home from the bar, 15 minutes after we got there. Don’t do that.

          • Nicolette Streete

            So if I’m using 1 stick of butter but I want it to have a kick… is 1/4oz a good amount to start with? Would you recommend having my boiling pot with a metal bowl and having the butter && ground flower in that until it’s done foaming? But keeping the water beneath by bowl between 180 & 215 F? Also is there a particular color to strive for or to stay away from?

          • Hugh G. Cock

            2 sticks if you get most of the butter smashed out of the weed. It won’t be super strong. I use 2 oz. of ground up bud to 4 sticks of butter. You have to be a mental cosmonaut to handle a gram of that.

          • Nicolette Streete

            After you strain the ground flower, is there anything you can use the “butter covered cannabis” for?

        • Frank Gorman

          so true

    • Jacob Senji

      Totally agree with you man. I have been at it for around 25 and this is the way we get the best oils and butter. Been at it like this for around twelve years now. I was just surfing and seen this so I thought I would give you a rep. Later man. look for me @ 420 mag

      • Hugh G. Cock

        Awesome to be vindicated by someone from 420! Thanks man, I appreciate the response. You just can’t tell some people anything without it becoming a p***ing contest.

        • Just Another Earthling

          🙂 While I agree with “Most” of your posts on this topic.. It’s rare that I find myself agreeing with “Hugh C. Cock” type persons! lol .. Dude > Whatsyername? and dont’ tell me it’s Dick! 😛 lol

    • Dianna Donnelly

      Forget sweets and go savoury. Canna-bacon tastes like bacon. Yum.

    • Mathew Tyme Eldridge

      You sound biter about the taste of weed. If done without any care, yeah it taste like shit but weed can add some awesome flavor if done correctly. I made a lemon meringue pie with cannabis once and the flower really made it something special. No ass taste, just good lemon flavor complemented by the weed. too much weed and it starts to taste funny like you said but just the right amount is great. Too much of a good thing is never good.

      • Hugh G. Cock

        I used to be a biter, but my mom cured me of that. Joking aside, I like the taste of weed butter, and I like the taste of food, but the two don’t work for me. I don’t eat sugar or flour, and anything else I cook isn’t going to be enhanced by the taste of weed. And if you make sweets, you can’t eat anymore when you’re high or you’ll make yourself miserable. Why not just eat the butter, then you can eat as many sweets as you like, and just get fat instead of insanely loaded?

    • Andrea Pea

      Hi..if I have approx 1 gram, how much butter / oil would you use. I have a very small amount to try for chronic pain. Thanx

      • Hugh G. Cock

        That’s really not enough to make butter. You could probably use a 1/4 stick of butter, but you’d have to really watch it and not let it burn.

    • Gwen

  • Alex Lake Hill

    hi guys,
    i need to make some brownies in the next couple of hours, i have pre-made brownie mix and will need to make the oil from scratch, can i just put fresh bud in the oil to activate the thc or do i need to prepare it in the oven first ? also can i just find the weed and melt it with butter ?.
    many thanks and if anyone has any better suggestions please let me know!.

    • Lucas

      For a quick batch, use the oven to decarb (220’ for 30-45 minutes) then melt your coconut oil and add your decarbed plant matter. let it simmer on med-low heat on the stove, constant stir for about 15, strain and add to the brownie mix. Best route for a quick use!

      • David Blazith

        There’s about a million and a half recipes floating around the internet. All with different temps and times and such. Why, Lord? How long must the evil triumph on Earth?

    • The CannaCraftsman

      The best Brownie recipe I have have made is just grind the herb (finely). I use a bullet blender and I just put the powder directly into the brownie mix, be cautious it is very strong. Also of course take the stems out, as not to have stems in your brownies. .. lol I did had the first time. 🙂 Stay Medicated & Happy

  • Robert George

    Can you use this oil in vapes?

    • Kevin Berg

      nopppe this is of baking and food, i believe oil is a variation of shatter which is made via BHO

    • Dianna Donnelly

      You can do a similar process but use Vegetable Glycerin to absorb the cannabinoids instead of the Oil.
      That can be vaped.

    • BoBoBolinski

      I use 5gms bud, 100 ml oil. Biggest problem is not letting the plant material burn.I found it better cooked in a very small casserole dish for 25 mins, gas mark 6.Let cool with plant in oil , then strain into a clean jar, buy empty capsules on Amazon and fill with a disposable pipette.

    • cvmoonshadow


  • Janice Dre

    doesn’t heating on low over long periods of time, like in a slow cooker for several days, as noted in the article itself, also allow for decarboxylation?

    • Fred C Youberg

      I don’t see a direct answer to this question in this thread. I have the same question. If you heat your coconut oil and cannibus mixture for six or seven hours at say, 215F, won’t the decarboxilation have taken place? Why is decarboxilation typically described as a separate step?

      • Chevy Swish

        I slow cook my butter and oil on low in a crock pot for a minimum of 24 hours. 1lb of dried flowers and 1lb of butter, never scorched, and everyone is always scared to eat my edibles.

        • John Blaska

          Decarbing 1 lb of weed at once.. WOW. Talk of the town I’d be! Rather smell of the town. Decarbing that much weed at once might just get the entire neighborhood a contact buzz!! I walk a bit more softly, but my sticks mighty! I use a 1/2 ounce in 1 1/2 cups of butter. When ready, 1 saltine cracker with a lil spread of butter is more than enough for anyone I know. Eat that cracker and 3 hours later,,chilllll. Best buzz ever. So much stronger than smoking and the effects last 8 to 10 hours. I love all you happy folks. Stay safe!

          P.S I always use low to zero sodium butter.

  • LeoTheEngineer

    Let me know if this will work.

    1. Ground bud (7g) into slow cooker
    2. Add 1/3 cup coconut oil and some water to slow cooker
    3. Let it cook on low for 1.5 hours
    4. take out infused oil with the trimmings and add to already made brownie mix
    5. Put weed infused brownie mix into pan and into the oven on 350F for 33 minutes.

    NOTE: I am going to get decarboxylation for 1.5 hours in the cooker and for 33 minutes in the oven. Is this good enough?

    • Shaylynn H.

      Not worth the effort, dear. If you warm your butter or oil with weed and add to the brownie mixture (5 minutes or so), you will get a good high. No prior steps necessary. Just be sure you heat the weed with the oil/butter (butter has a better taste) to activate TCH before adding and baking. Have done this a lot – great results. 🙂

      • Chris Anderson

        his name is Leo the engineer. Homie is going to use a process xD And in his defense you can reach much higher concentrations of of not only thc but all of the medicinal compounds by being meticulous. MTC coconut oil can also be used for the cleanest results from a pharmacological perspective from what i understand.

      So how well did it go..????…This sounds like it would work and I am getting stuff gathered to make some brownies — Right now……..

      I fear your slow cooker. They seem to vary in temperature.

      Decarbing for THC: 240degF for 1 hour
      Decarbing for CBD: 240defG for 2 hours (although I’m starting to see people posting 1.5 hours)
      But going past those temps/times could degrade your cannabinoids.

      Safer to infuse at a known lower-than-decarb temp (I use 150degF for 12 hours). Then bake at the decarb temp/time (do your brownies at 240degF for 1 hour…they won’t “rise” as much, but you’ll have a more consistent dosing!).

      Okay…so how to control your temp? If you’ll allow me to recommend a temp controller:

      It’s from Amazon…and I have a love/hate relationship with them. But any similar unit will work:
      …set it for 150degF
      …plug your slow cooker into the “heat” outlet of the unit
      …insert the thermocouple into the oil
      …infuse 12 hours.

        I saw a graph where they used scientist methods to test the strength of pot after decarb and the winner was to bake at 250 degrees for 27 min! It was all downhill after 30 min. Longer and cooler did not make the pot reach its fullest effect. This was the only scientific study I have ever seen.

  • Sean

    Is the finished oil active and ready to be used for applications other than baking/cooking? For example, can this oil be ingested by itself, or does it need to be cooked/baked in something?

  • di from Oregon

    Gosh, my girlfriend made me some infused cookies by putting 2 C. coconut oil in the crock pot, adding one handful of Purple Hindu Kush, letting it cook in, adding a second handful and letting it cook on low for 2 days. Makes very powerful cookies.

  • KJ B

    Great article, really easy to follow! If you’re too busy to make this at home, or too impatient (like me), you can order cannabis infused olive oil online here:

    • tommus

      can i buy cannabis infused spam there?

  • G Bernard Grant II

    so i’m completely new to this…and tried an incredible edible, and wanna get in on making it myself. My thing is idk these sizes you speak…from a street value perspective, how much would i need to purchase to make an effective amount of this stuff? like 32 oz bottle of say canola oil. I see it says 1 cup – but idk how much that translates into

    • Linda Lawrence

      that oil is called rape seed oil, it’s not a safe oil internal use.

  • NickR

    I have a bunch of water extracted hash/keif. Can I mix this with coconut oil to use with cooking. Does it need to be warmed to the same temperature as bud would?

  • just so u know, it’s hemp oil…can’t sell across state lines to noncompliant states…just can’t….so these are hemp oil products…ask….

  • What if it’s just the sticky wax? How could I bake with this?

    • If you heat up a little coconut oil or butter, the wax should easily melt into that warm oil.

  • PierceEye

    I just made a batch of infused olive oil, 1/4 oz of bud I decarbed for 30 minutes @ 240F, a little more than 1/2 cup of virgin olive oil
    Instead using a standard crock pot I used a Crock Pot Little dipper as it keeps a nice even temp of around 175-190
    I brewed it for 14 hours, strained it and added bread dipping spices, using about a tablespoon of infused oil and some nan bread dipped in and 30 minutes later I am one happy man!

  • Fred C Youberg

    If you heat your coconut oil and cannibus mixture for six or seven hours at say 215 degrees, won’t the decarboxilation have taken place? Why is it always referred to as a separate step?

  • David

    I have cannabis oil and would like to use it in my Banana Bread does anyone have a great recipe. Thanks

    • ImdaPrincesse ™/MsWonderFall

      Better Homes and Garden has a fabulous one..

  • Devon Campbell

    if i am significantly reducing the amount of oil or butter that is being used does that decrease the infusion time? I am wanting to use about 1/2 cup of oil/butter to 1/4 oz mj using a double boiler.

  • FoodForSavages

    If I want to use 2 cups of coconut oil how much weed should I use?

  • Sandie Shafer

    Can you use decarbloxylation flower to make counnut oil? If so dose anyone have recipe?

  • shumee

    So decarbing is just for the psychoactive effects? If I am just concerned with healing, do I need to decarb?

    • emrsonbiggins


  • James White

    How to sensibly buy LEGAL cbd oil? Because I got a letter saying customs has confiscated my package two times already and I’m pissed.

    • ImdaPrincesse ™/MsWonderFall

      Where are you buying from and shipping to?

  • walt socha

    For those making brownies: don’t need to decarb. Just infuse into your choice of oil (I use coconut oil at 150degF for 12 hours). Then use a commercial brownie mix (which typically calls for 1/2 cup of oil). Then (instead of baking at 350degF for 30 minutes) bake at 240degF for 1 hour 10 min. The decarbing occurs while baking.

    • Kerri Dexter

      Why? Walt why am I infusing the oil at a lower temp for longer and doing the same with the brownies? Why low and slow like cars in the 90s?

      • walt socha

        Not sure what your question is. But here’s what I think I know:

        I don’t want to do three heat steps: decarb the herb, then infuse it, and then bake…because the baking is likely to degrad the already decarb herb. So I decided to let the baking do the decarbing.

        Performing the infusion at 150degF helps get the THCa, CBDa, and the rest of the cannabinoids into the oil. But that temp is too low to break up the THCa into THC and CO2. So I am able to do the decarb during baking. I find a brownie mix that needs 1/2 cup oil (which works for the proportions of ingredients that I use) and bake the brownies at 240degF for 1 hour 10 minues. (The extra 10 minutes just seems to help bake the brownies…but isn’t long enough to affect the decarbing “thermal history”).

        Why do two heat steps instead of only one heat step? The 150degF infusion temp is too low to decarb but high enough to infuse (especially for 12 hours). The 240degF (1 hour 10 minutes) baking temp is perfect for decarbing.

        I don’t want to over-decarb as the THC will break down into CBN (which has less intoxicating and less medical uses). (Note: that’s CBN, not CBD…another subject altogether…and that requires 240degF for 2 hours to decarb).

        Note1: I’m a bit concerned about baking at 350degF. I fear that will break down the THC.

        Note2: I usually get 32 brownies from a batch. With a max dosage of 1 brownie. (I use them for sleeping).

        I hope I have muddled the issue!

        take care,

        • Brook

          So are you saying just out the weed in the oil, and mix it in with the brownie?

          • walt socha

            Yep! Need a bit of temperature to help the cannabinoids (which are fat soluble) infuse into oil (I prefer coconut oil from Trader Joes!). But no so much as to get into the decarbing range.

            Then “bake” at the decarb values: 240degF for an hour. (My last batch was a bit crispy at 1 hour 10 minutes…so I may drop back to 1 hour).

            Again: I fear that infusing at a higher temp followed by baking will process the THCa past THC into CBN.


            PS…oops…had to edit my above post…typo! (THD instead of THC)

          • Martin Mondello

            If your putting all that time and effort into infusion, don’t use a box mix anything. It works, but why not extend the effort and make your edibles from scratch. Always better tasting in my opinion, but I am a chef by profession 😉

        • Mark fusa

          skip a step raise heat to 190F and it decarbs as it infuses, also add powedered lecithin to aid in your bodys ability to absorb the oil….as a diabetic I cant make broiwnies and cookies but do make caps so I take them, no sugar same meds, eat with dairy for better absorption as well…I like a bit of yogurt…

    • ryuku

      Hey Mr,Socha
      can I infuse a cup of weed an half a cup of olive oil ?
      thank you

    • OnTheBayou

      Walt, your cannabis is not leaving 212 degrees until the water has left. Presuming sea level. Decarb will start increasing as water leaves and not very much before. Of course the center is the last place for water to leave. In fact, any Brownie that is moist, still is loaded with water. Which means it’s been slight decarbed at around 212 degrees.

  • Carrie

    do you need to decarb the weed before putting in the crock pot with the oil?

  • barbarabauer

    or you can melt some butter in the microwave and put some weed in it and throw it back in the microwave for 2 or 3 minutes. then soak it up with crackers or cream of wheat or whatever you like. variant- slice bananas and put it the melted mj butter and replace in microwave for a couple of minutes.

  • Natacha Lalande

    Coconut oil is popular also to infuse because of how higher you can heat your coconut oil, compared to olive or vegetable oil for example.

  • Rob Michael

    Okay here two methods I have done and I have made about a dozen batches. I am not saying I am an expert but I enjoy the hell out of making treats with it.

    Brownies, I take about 10 grams of flower and grind the holy hell out of it, take a store bought brownie mix and put in the mix and bake just like the box says. BOOM 23 minutes later I have small brownie bits that will knock your socks off. I have no idea the strength as that was my old method of using it. I did not Decarb it I just ground it and cooked it all together. YES it has a strong weed smell but the taste is not too bad.

    Now I make caramels which is a longer process but how I make it is this method:
    28 grams of flower 15-20% THC level. I crush the flower by hand so there is very little small grind/powder. I then turn on the crock pot on low and add 6 sticks of butter and start the melt. I put the ground up flower on a cookie sheet and cook at 225 for about 40-45 minutes. Take the Decarb flower and dump into the already melted butter and cook for 2 hours on low then 4 hours on warm, take it off heat and let cool for 4 hours and then put it back on warm setting for another 6-8 hours, pull it off cool it for 4 hours and do that one more time. I then put double layer of cheesecloth in a strainer and pour the mix and let it drain until I can’t see anything else dripping through. Then I fold up the cheese cloth and wrap another layer around that and squeeze the extra butter out. YES I know, I know I am adding a slight amount of bitterness from the plant but I want to get as much of the THC as I can get.

    I mix and cool, mix and cool, mix and cool and the butter is a beautiful light green very flavorful mix.

    Now I make caramels with the butter and the recipe I use takes 1.5 sticks of butter for a batch which I make and pour into a mold and when I am done I have about 70 pieces at 10-15mg each roughly

    28gr = 28000mg X .15 = 4200mg per batch of butter. I get 4 batches of candy from that so each batch is 1050mg, 70 pieces of candy per batch equals about 15mg but since I know I lose some in the full process from Flower to Caramel I round down a little and say 10mg.

    I know this is not exact science but I share these with my friends and have yet to have a complaint. I personally like Sativa or good hybrid best and try to find 20% so the batches are stronger but I live where it’s not legal so I take what I can get.


  • Brian

    Cannabinoids are not stable in a solution.

  • Andre Berns

    Did you do the carboxylation process and subsequent slow cooking with the lid closed or open?

  • tariq dawson

    Can I use a 1/4 of herb to bake a box of brownie mix?

  • nouseforaname

    According to all the temperature charts I could find, THC, CBD, CBN etc. will not be released below certain temperatures and 245 degrees Fahrenheit is way to low. If I vaped at that temperature I wouldn’t feel anything. So how come I need to vape at higher temps but decarb at lower? How does that scientifically check out?

  • Just Another Earthling

    ok .. still just as confused. The last bit where you instr. “Note: Be cautious when using the oil to prepare dishes that require heating. Do not microwave and choose low heat whenever possible.” But .. I wanted to make the oil to COOK with ..make brownies .. etc.?? So .. Now what?
    This is the part that confuses me .. Decarbing activates .. So .. Why not just cook with the herb (as a flour)?
    I really don’t get this decarbing if I’m making brownies.. HELP!!

  • Susan G. Feltman

    I am lactose-intolerant, and want to use vegetable shortening in place of most or all of the butter in my baked goods. Is it possible to infuse cannabis into vegetable shortening?

  • Jeanine

    Hi new to this and wondering if you have any helpful hints for cooking my green. Do you have favorite tried and true recipes, etc… Thanx

  • Charlotte

    Per scientists in Holland, the ideal temperature and time for maximizing THC production is 230 degrees Fahrenheit for 1 hour and 50 minutes in a slightly acidic environment. Using just a fat/oil and the plant’s natural pH is perfect it says.


  • Mark fusa

    ya one pound butter will barely get a pound wet, but decarb in slow cooker as it goes for 18 hours or more does work best, no loss to decarb in air, if not fully sealed your thc and terps evaporate, if you can smell it you losing medicine, so submerged in oil it gives it up to oil…

  • Renzo

    Why its not necessary decarb the cannabis flower when it’s for oil. And its necessary for butter?thank you

  • KK

    I think I used a cup of dried flowers, But it explains why people are afraid to eat his brownies. I am down for the challenge!

  • Erick Hill

    Try using Muslin instead of cheesecloth. Muslin has a tighter weave which allows less matter through, without sacrificing yield. If you have no big stems, you can press it without worrying about material.

  • Todd P

    What if my oil has exceeded 245 F ? Is the oil now garbage or will there be CBD left? Is there a chance there is THC left in the oil?

  • You skipped the decarb process which is essential. Otherwise you’re not getting the most of the cannabis.
