A safe and simple way to infuse cannabis in your slow cooker for effective weed butter. Just a few steps and ingredients that is difficult to mess up with. A step-by-step instruction manual for a foolproof Cannaoil recipe made and decarboxylation in a crock-pot for four to six hours.
How to Make Cannabinoid CBD Weed Butter in a Crock Pot
We started these recipes exploring different ways to extract cannabinoids a little fearful of what our neighbors may think. That was week 1.
At this point, F it, right?
Let’s make cannabis weed butter. Teach those neighbors a thing or two about a thing or two.
Why a Crock Pot for Making CBD Butter?
So glad you didn’t ask!
First things first. Is it CrockPot or Crock Pot… or Crockpot?
I’ll call it a slow cooker since google trends show’s slow cooker as trending.
Infused Cannabis Butter in a Slow Cooker is Dead Simple
Slow cookers make busy lives seem simple. Nothing like coming home to a hot bowl of chili that sat in the cooker all day.
Well, even better coming home to some cannabis butter. You’ll know it’s ready when your nose is near the front door – we promise.
Speaking of, if you want to limit the decarb smell because you live near neighbors, check out our mason jar tips.
Ardent Nova Decarboxylator
“Better than I imagined.Very slight smell but hardly noticeable.Fast and gets the job done with minimal cleanup.” ⭐⭐⭐⭐⭐
Levo Oil Infuser
“This machine can make infused oils dressings coconut,olive,vegetable oil infused in hr or so no smell no waist.” ⭐⭐⭐⭐⭐
Slow Cooker CBD Butter Limits Burn Risk
We also love the slow cooker because as long as you keep it on your lowest setting, there is very little room for error.
Nothing feels worse than having to throw out a batch because you scorched off the cannabinoids.
So just like our motto when experimenting with edibles, slow and low is how we like our slow cooker CBD butter.
How to Make Cannabis Infused Butter (or ‘canna butter’)
Cannabis infused (CBD, THC, CBN…) butter is a staple in the edible cannabis connoisseurs pantry.
Butter is delicious and CBD butter is delicious-er. At least to us.
Infused butter is a versatile carrier for THC and other cannabinoids.
We abide by a few truths for making this butter.
- Don’t burn your product, and
- Always decarboxylate your flower, and
- Use our dosage calculator to know your limits
You don’t need very many items for this recipe — just time really. It’s a set it and forget it type process.
Just remember to stir from time to time to really help the extraction process.
Tools for Making CBD Butter in a Slow Cooker
- Slow cooker (aka. Crockpot)
- Strainer (cheese cloth or metal strainer)
- Container (you can use a jar or molds to make a butter shape)
- Spatula (good to the last drop)
Slow Cooker Infused Butter Tips
First, we suggest adding a little water to help reduce the risk of burning if you don’t trust your slow cooker. It will most likely evaporate away while cooking but, if not, you can remove it after the butter hardens and separates from the water.
Second, keep the temperature on low – about 160 degrees. Under 200 degrees is our target. Anymore and you risk burning off the terpenes and wasting the cannabinoids.
Also, you really only need to let it go for about 3 hours and then you can begin cooling. Some say longer is better, but if you are in a rush it’s better to limit the time than to crank the heat (see above).
Simple Crock Pot Infused Cannabis Butter in a Slow Cooker
A simple and safe way to extract cannabinoids for infused butter. 3 ingredients and a crock pot is all you need to have some long lasting and effective infused THC or CBD weed butter.
- 2 cup Unsalted butter – around a pound
- 1/2 ounce Ground and decarboxylated cannabis – around 15 grams
Set your slow cooker to low, or around 160ºF. (Stay under 200 degrees to prevent degrading the cannabinoids)

Do you have a lid on the slow cooker
Do you add any water ?
I used to when I didn’t have have a digital crockpot with temperature control. If you don’t trust the low setting, I recommend throwing in a cup of water (or more, it really won’t impact anything) to keep things from burning. After you strain it, you’ll need to let it sit in the fridge and allow the butter to harden and separate from the water.
Hope this helps!
something I did that made this even easier was to make a tea bag with cheesecloth and knot it tightly. Once its fullysteeped (I also went over 3 hours) I used a metal hand lime squeezer that I bought at a local Fiesta Foods and squeezed everything I could out of it… all without getting any on my hands. Waste not want not… ammirite? Excellent method Thank You.
Wow, nifty! Does any of the plant material end up in the final product when you do the lemon squeeze? Sometimes when I squeeze too much it can taste a little extra “weedy” but I think I’ll try your tea bag and squeezer method.
Appreciate you and stay groovy!
I drink a lot of tea, so I put my decarbed MJ into new tea bags and place in my jar of oil or butter and cook it in my slow cooker for 4-8 hours. It’s the bomb on toast and in my green beans, ham and onions!
You are so right I used mesh bag and tied it as a tea bag. I also cooked it in the crockpot for 20 hours at a temp of 156-160. It turned out AMAZING thank you so much
Can I use unsalted Irish cream butter
Absolutely. (and that’s my favorite type of butter.)
Hi do I still need to add lethicin ?
Thank you in advance
Yes its The best butter to use, kellyegold unsalted
How long do I put it in the oven before I grind and put it in the crockpot?
Hey there Natalie,
It depends on what method you are decarboxylating with – take a look at our 3 mason jar decarb methods to get an idea. Primarily, no less than 45min. An hour seems to be ideal. We plan on getting ourselves a potency test kit soon and run a bunch of experiments on the best ways to decarb. Let me know if anyone finds interesting in such experiments, and we can expedite it.
Stay groovy out there,
Ok dumb question… I put the butter and the decarboxylated weed in the crockpot together to cook then strain it into the mason jars. I need specific instructions please. First time maker thank you…
Yup, that’s pretty much the steps. How’d it turn out?
The website LITERALLY gives clear instructions… Couldn’t be any clearer
Can I use coconut oil instead of butter?
Absolutely, and it’s the exact same steps.
Must you HAVE to decarboxylate the weed before you put in crock pot if you plan to cook for 8 hours on slow cook?
You don’t have to… but we highly suggest it. People do swear by the results of not decarbing with the long cook time and heat in the crockpot should technically do it. But take a look at these results over at and Ardent test showing the results of a decarbed vs non-decarbed infusion. Might change your mind.
I’m doing it inside of a Mason jar, Inside of a crockpot at 160 with water Should I put water in the jars?
Nope, no need! The water around the jar is all you need.
This makes no sense! 2 cups of cannabis is not 8grams. I followed this recipe and had to call an experienced cooker cause these measurements are horribly wrong. What am I missing? Am I reading it wrong?
Thank you! I was soooo confused about the quantity it states as clearly 2C does not equal 8g..
Are you referring to making the butter like that? Or, are you talking about decarbing?
This post is just about making the butter utilizing pre-decarbed cannabis.
Can I reuse the weed “sludge”with more fresh weed next batch?
Hey there James!
You know, we’ve heard of people using the “cannabis pulp” (we like to call cannapulp) for steeping tea, spreading on toast and even for a pesto or salsa. Never heard of it for a second go at a canna-infusion. Most of the time, your first infusion doesn’t extract 100% of the cannabinoids and terpenes, so no reason you couldn’t give it a go. The only worry would be dosing. No idea what percentage of the cannabinoids remain and adding in new decarbed flower will become difficult to measure. Otherwise, be sure to store it correctly and make sure it’s not spoiled on your next attempt.
Let us know how it goes and stay groovy!
It’s also great in protein shakes, FYI!
Do I need to use no salt butter and why?
Salted or unsalted butter are both acceptable, Krissy. Ole folklore used to believe that if you used salted butter, you’d have less “room” to absorb all the cannabinoids into the butter since salt is already in there. That doesn’t seem to hold much weight, so salted or unsalted is just fine. We only prefer unsalted because some recipes call for unsalted and it’s pretty damn hard hard to take salt out of butter — much easier to add it into the recipe
Light up, breath out and stay groovy!
can u decarb weed at 180° F.
Hey there mr.mighbewrong (clever, but not to worry)
I’ll answer your 3 questions here.
You didn’t funk it up. We prefer slow and low here, but others live by 220 to 300° F (high and fast). The only way to funk it up would have been going into the 315-325° F — that’s when the THC activates (same as lighting a bowl). You would have burnt it off.
Light up, breath out and stay groovy!
Do I have to infuse the decarbed weed right away? Or can I store it a day or 2 before making my cannabutter?
Hey there Candy Kane. No need to use right away. We store our decarbed cannabis in a cool, dry place within a glass mason jar. Haven’t looked too deeply into exactly how long it will keep, but it should be quite a while. Only worry would be degrading potency of the cannabinoids and terpenes. As long as it’s dry, nothing dangerous should inflict it.
Light up, breath in, and stay groovy!
can u decarb weed at 180°F
When baking cookies most recipes call for baking at 375. Does that cause anything to burn off or should I bake at a lower temp for longer.
First time butter maker. I attempted with a small 2gram and 1 stick. Major fail. I didn’t decarb it. I’m trying to make this for pain relief. How much weed for 1 pound? And how much will be I. Each teaspoon of butter? We use a teaspoon of butter in our coffee and I thought this would be better than making a sugary treat (which my pre diabetic body can’t handle).
I was wondering the same thing! Also I heard if a receipe such as brownies calls for adding water…NOT to add water. Newbie bud here so im curious to learn before I bake also!!
I used water because I don’t trust my crock pot but now the water doesn’t seem to be separating out and my butter won’t solidify! Any idea why.
hmm.. the only time that’s happened to us we were testing not straining the herb from the butter and just placing it straight in the fridge. Did you strain out the leafy greens first? Have heard of people pressing cold butter/mixture to get out water too, but we haven’t tested this ourselves.
First timer here… How do you suggest the detox when using pure shake? Thanks much in advance
Do I have to check on it often or stir it after adding it into the crockpot or can I leave it?
I have made several batches of canna butter, experimenting with very fine strainers, cheesecloth,etc. I I have found the BEST way to retain the MOST amount of infused butter is to use a French coffee press! No mess, no fuss. Just use a lot of force to press is much liquid out of the flower as possible. Then that butter/ water mixture goes into the fridge to separate the water from the butter.
I’ve gone to set it into the fridge it’s a light brown green sludgey texture ( I have strained this ) will it be okay ??
How long does this cannabutter last ?
I don’t have any mason jars, how else can I do this in a crockpot
The best recipe ever. I just turned 73 years young and have tried many recipes since 1964. Love this by far. Thank you so much. So easy that I probably be using this cannabutter for everything! Well I will be using it always. Makes the best 420 NY cheesecake.oh happy daze!
Can I leave it in the crockpot longer than 3 hours?
Yup. Should be just fine.
Hey guys. HOW is there info online that to decarb you go 225F in the oven but then in slow cooker not more than 200F or it will destroy the “high element”? isn’t that a freaking contradiction? what is the best temperature before it is too high? and why decarb if almost the same temperature is in the crockpot? do 10 degrees really make a difference?
MJ community really lacks logic, consistency and unity, that’s sad-i still think these are the smartest people out there. all the best friends!
Well aren’t you full of opinions and judgments…
Can you reuse the cannabis flower a couple times using this method.
I made brownies and they are way potent, trying to get more butter out of the flower if I can
i too am curious about the cooking heat for bake goods..do we need to adjust that or is thc held in or absorbed by the batter and surrounding ingredients as it cooks? Also a newbie!! i will say my first batch made very potent very tasty cookies so my guess is no it doesn’t matter
very informative page . TY
I’m a first timer. I used coconut oil. How long to I cool it before I strain it?
Hey there Janet. I tend to just wait until I feel comfortable with the temperature. No rule on this, I just don’t enjoy burning myself
Hi, I’m planning to make this recipe today, but I am making 28 grams worth. I noticed the recipe is for 8 grams, would it work for me to just triple or quadruple the recipe? Also, would I want to cook it for longer than 3 hours when using more material?
Thanks for the help and for the great content!
Hello. In regards to the decarbing… I have been making cannabutter since roughly 2001 (just giving an idea for reference of how many times I’ve made it since then). I don’t decarb, I didn’t even know that word existed Haha but what I do is use 4 sticks of butter for every half oz. of scraps, shake weed after harvesting seeds, older drier weed, lower grade weed, etc… I add the 4 sticks of butter to the crock pot on low and let melt and then I add the ground up weed. I let it sit on low/ medium depending on the strength of the particular crock pot and let sit without touching for roughly 6-8 hours. Afterwards I then pour(over a strainer) into a big plastic cup such as a “big gulp” cup from 711 or anything rubber/ plastic that can be squeezed after letting sit in fridge for 24 hours. Everything good in the cup, which becomes the butter, rises to the top which I then gently squeeze and remove. It will be about 1 to 2 sticks of butter in the shape of a disc at that point. Use as you would in any recipe. You can also adjust the amount of weed because I will say using this method you get SUPER POTENT BUTTER. So strong that I actually became frightened the first time after eating two cookies lol well good luck that’s my non decarb method because I think the heat in the crock pot does a decent job of activating the good stuff imo
How To Make Cannabis Oil – Crock-Pot Method
It seems like every day that passes cooking and cannabis each become more popular. So, it only makes sense that cooking with Cannabis is becoming more popular but how do you infuse foods of all shapes and sizes with THC? In college baking pot into brownies got the job done, kind of, but now that we have sophisticated cannabis grown by professionals with college degrees and lab grade technology do we really want to pick ground flower and stems out of our teeth on our old college brownies? My name is Herb Hightower and buckle in for a culinary adventure where we’ll learn how to prepare our favorite foods with a cannabis twist from sauteing veggies, adding flavor to salads, or finally updating and improving the old brownie recipe.
Crock-Pot Cannaoil Recipe
While you can make Cannaoil many different ways, the reason you may want to cook in a crock-pot and the reason we chose this method is so you don’t stink up your kitchen or the entire house as well as making cleanup a breeze. To make it even easier than a soupy mess in your crock-pot that sucks to clean and makes you worry you’ll get the kids stoned next time you try a pot roast, pun intended, we included a mason jar into the mix and added a water bath to the crock-pot. Also, most crock-pots don’t get that hot, even on high, so you don’t risk burning off the THC with this approach.
What Type Of Oil Makes The Best Cannabis Oil
When making cannabis oil any type of oil will work but not all oil is created equal. Extra Virgin Olive Oil is good for flavor and heart-healthy fats. Pure Olive Oil has a higher smoking point, not as flavorful as Extra Virgin Olive Oil, but you can fry with it. Vegetable oil is good because it has a neutral taste and a high smoke rate. Coconut oil is all the craze right now and great for vegan-friendly recipes. Avocado oil is not the most price-sensitive option but has the same heart-healthy fats as Extra Virgin Olive Oil and another option for high smoke rates which again doesn’t burn at high-temperature baking. We chose to use Extra Virgin Olive Oil for our recipe because that’s what we had in the cupboard and has always been the tastiest oil on the block according to my tastebuds.
What Kind Of Cannabis To Use
We’ve been reviewing High Level Health’s massively awarded cannabis flower in our blog for over a year. All posts can be found in the news section of this dispensary website. Since we’ve done a lot of reviews, we’ve collected a good amount of amazing marijuana. So, we decided to use a conglomeration of ten different strains of quality flower, from some of the strongest Sativas and Indicas on the plant to heavy CBD strains to make this batch of Cannaoil!
Steps To Make Cannabis Oil In Crock-Pot
Step 1 – Add Ingredients To A Mason Jar
Ground Cannabis Strains
Once you’ve selected your choice for oil, again any oil will work but each oil will serve a specific purpose and our choice was Extra Virgin Olive Oil, combine a one-to-one ratio of oil to cannabis. Our ratio was a combination of different strains making up an ounce of premium, award-winning High Level Health ground cannabis to one cup of oil. We came to this ratio by first lightly grinding, don’t over grind because the flower will go through your cheesecloth later in the straining process, our cannabis in a traditional hand grinder, and our one ounce filled a single measuring cup. So, as long as you go with the one-to-one ratio you’ll have infused some potent oil with cannabis assuming your pot was potent, to begin with. You can manipulate this ratio by adding more cannabis or more oil to strengthen or weaken the end product. In the end, you’ll want to combine your one-to-one ratio of cannabis to the oil inside of a mason jar and then hand seal the jar, no need for the old-school sealing of the jar like the pickling process, just crank down one time hard on the lid and you’re set.
Step 2 – Add Mason Jar To Crock-Pot
With your awesome, slushy mixture of cannabis and oil gently place the sealed jar into the crock-pot which you have previously filled with ¾ of the way full of a water bath, and return the crock-pot lid over the stoney science experiment. Another great reason to use the crock-pot method versus the stovetop method is that you can set the crock-pot to medium or even high without fear of burning off the THC which can happen at 400 degrees Fahrenheit as most every crock-pot will not heat up that high. I like to place a wireless thermometer in the bottom of the crock-pot water bath so I can monitor the temperature because the last thing you want is a rogue crock-pot getting too hot and killing the THC from an ounce of high-grade marijuana that you spent your hard-earned money on.
Step 3 – Cook Cannabis Slow And Low Then Burp
Temperature While Cooking
With this recipe, we are completing the decarboxylation process while infusing the oil with cannabis. Decarboxylation activates the delta-9-tetrahydrocannabinol or THC chemical and it needs to be done in some way, shape, or form to engage the intoxicating, psychoactive effects that we all know and love. You can decarboxylate in the oven beforehand to speed this process up by a few hours but again, risk the chance of stinking up your house. Also, the crock-pot method helps with controlling the heat throughout the entire process and makes it as easy as slow cooking a pot roast. Most, if not all, slow cookers don’t get warm enough to boil water as water boils at 212 degrees Fahrenheit, well below the 400 degrees that can render THC ineffective.
So, with your water bath situated somewhere between 175 and 210 degrees cook your cannabis and oil mixture for four to six hours. To avoid the chance of pressure build-up and explosion, which is extremely rare, burp your jar once during the first two hours of your cooking time by opening up the lid and resealing by hand as you did before. During the burping process, you can stir the mixture well and then place it back into the water bath for the remaining amount of time. We believe six hours total is the ideal time needed, but you can stop after four hours with similar results in a pinch.
Step 4 – Strain Spent Cannabis Flower
Final Cannaoil Product
After six hours in the water bath, remove the mason jar with oven mitts and set it on the counter to cool for five minutes. Once cool to the touch, cover an additional mason jar with cheesecloth over the top to pour the oil mixture through your strain collecting the spent cannabis flower in the cheesecloth(don’t throw this out just yet you can mix in brownies, pesto, or whatever you’d like as there is sure to be some THC left in the spent flower).
Step 5 – How To Use Your Cannaoil
Once you have your Cannaoil strained you can use this oil in any way you can imagine. Just substitute Cannaoil for whatever your traditional recipe calls for when baking edibles. So, if your brownie mixture calls for two tablespoons of oil you can substitute your Cannaoil in its place. Now if your first batch of edibles turns out to be too strong then with your next batch of brownies substitute one tablespoon of regular oil and then add just the one tablespoon of Cannaoil. Remember your potency will largely depend on the strength and freshness of your original cannabis flower so test your edibles in small doses to determine the strength of your end product before you share with friends to avoid overdosing. Get creative as well and try your oil in any way you use traditional oil but remember to not exceed that 400-degree Fahrenheit mark which would essentially burn off the THC in the oil.
Storage – Refrigeration Is The Best Bet For Cannaoil
Now that you have infused your oil it’s time to talk storage. First off, and hopefully, it doesn’t need to be said but please do keep this mixture out of reach of small children or anyone under the age of 21.
Best practices for storage include keeping the Cannaoil in a cool, dark place with the lid sealed tight on whatever container you feel comfortable with, glass is better than plastic and a mason jar works great but you can upgrade your storage with an oil dispenser glass bottle online for around $10. Storage in the refrigerator is best if you can keep it out of reach of children as the Cannaoil will degrade slower in a refrigerator than in your cupboard.
Hopefully, you’ve enjoyed learning how to infuse the oil with cannabis and enjoy cooking with Cannaoil even more. So, get out to the local High Level Health dispensary near you, grab some marijuana and let us know how your cannabis cooking experiences turn out by emailing us at [email protected] , we might just include you in our next food forward cannabis blog!
