Ingredient Notes
- Cannabis: The first step is to select your preference of THC, CBD, or CBG dominant flower, trim, shake, etc. You can purchase flowers from my online shop here. Then select your desired amount to use. Small batches can be made with as little as 3.5 grams; large batches can be made with up to 1 ounce of cannabis or more. Use the Flower to Oil Ratio Guide if you need help deciding how much to use. You do not need to grind the cannabis; just break the buds into small pieces.
- Butter: The next step is to choose unsalted butter, clarified butter, or ghee. You can also use this infusion process to make cannabis oil with olive oil, coconut oil, MCT oil, vegetable oil, etc. You will not have to remove milk solids from canna oil at the end of the process.
The Step-By-Step Process
Step 1: Lay a clean dish towel down on the bottom of your crockpot. This will help to prevent the mason jars from moving or cracking during the process.
Step 2: Fill your crockpot at least halfway with hot water. You want enough water to cover the sides of the jars you plan on using. However, be careful not to add too much water, as it may overflow when you add the jars.
Step 3: Place a thermometer in the water and set the crockpot to high heat. When a temperature of around 180Ā°F is reached, turn it down to low heat. Note: any low temperature between 180-190Ā° Fahrenheit will work. You may need to adjust to medium heat, depending on your crockpot.
Step 4: While the water bath is heating up, measure your desired amount of cannabis flower. Use the Flower to Oil Ratio Guide if you need help deciding how much to use. Record how much flower you used, in grams, so you can calculate your final potency with the edible dosage calculator.
Step 5: Gently break apart the cannabis buds by hand into popcorn-sized pieces and place them into a mason jar. Do not grind. Gently put the lid on the mason jar and place the jar in the oven for decarboxylation. The decarboxylation process is simple and can easily be done in an oven or Instant Pot. Bake at the time and temperature needed for each specific cannabinoid, see notes below.
- THCA to THC ā bake at 240Ā° F for 40 minutes
- CBDA to CBD ā bake at 240Ā°F for 90 minutes
- CBGA to CBG ā bake at 220Ā°F for 60 minutes
- THC to CBNā bake at 240Ā°F for 180 minutes
Step 6: After decarboxylation, place your butter or oil of choice into a mason jar (or another jar with a tight sealing lid). You may need more than one jar to make a big batch.
Step 7: Add your decarbed cannabis to the jar. If you are using more than one jar, evenly divide the ingredients between the jars for more consistent dosing.
Step 8: Wipe the rim of the jars with a clean towel, and add the lid. Tighten the metal ring to finger-tip tightness. It should be tight, but not too tight.
Step 9: Carefully place the jars into the water bath, put the crockpot lid on, and leave it alone to cook for 4 hours. You want to maintain a temperature of around 180-190Ā°F the entire time. If you don't have a lid, aluminum foil will work.
Step 9: After the 4-hour cooking time, carefully remove the jars from the water bath and allow them to cool enough to handle. You are now done with the crockpot step and can discard the water bath.
Step 10: While the butter is cooking, prepare a straining area. You can use a coffee filter with a funnel, a fine-mesh strainer, cheesecloth, or a French press.
I do not recommend using anything not food-safe, like pantyhose. Pour the melted cannabutter through the strainer to separate the plant matter from the infused butter.
Don't forget to save the leftover plant material, also called the pulp, to use in other recipes.
Step 11: Add the strained butter to a container you would like to cool it in. A flexible container works well. You can also use butter molds. Place the container in the refrigerator and allow it to cool completely (overnight is ideal).
Pro Tip: If you're using butter molds, place the molds on a baking sheet to prevent them from spilling. Then use a spoon to get the pure, infused butter into the first two sticks of the mold. The third stick will contain the remaining infused butter and milk solids. You will then only need to remove the milk solids from one stick. The fourth stick will remain empty due to the loss of water volume during the cooking process.
Step 12: While cooling, the infused butter will harden and solidify, leaving a bit of liquid underneath. When completely cool, remove the solid block of butter and drain the liquid (it doesn't contain anything worth saving).
Your cannabis butter is now ready to enjoy š
Storage Instructions
Store your finished product in an airtight container in the refrigerator according to the expiration date on the butter you used. You can store it for a long time in the freezer. If you keep it in the freezer, wrap the cannabutter in individually sized portions to ensure easy and convenient dosing. Learn more about how to store edibles here.
If you store the butter in the fridge or freezer, never use the microwave to soften or thaw the butter, as it could ruin the final product with too much heat. Use my guide to get your cannabutter to room temperature safely.
Notes & Expert Tips
- If you are new to edibles, check out my beginner's guide to edibles first. They can be difficult to dose and even more potent than other forms of consumption. Friends donāt let friends eat edibles unprepared, so let me help you!
- If youāve never cooked with cannabis before, consider starting with CBD flower to make CBD butter. Experimenting with a more affordable option means less heartache if an accidental mistake is made along the way.Ā
- Be mindful of how much cannabis you add. Adding even a small amount to a cup of butter can result in a high final mg of THC. Before getting started, use my edibles dosage calculator to determine how much you should use.
How to Use Different Product Types
Using buds is one of the most common ways to make butter, but it's not the only way.
The best part about making pot butter is that you can use any type of cannabis you want.
Aside from seeds or roots, all parts of the cannabis plant contain some cannabinoids that can beĀ infused into butter.
Some parts of the plant, like the buds, contain more trichomes than other parts, like the trim leaves.
Here are the most popular options to work with. Keep in mind that how much you use will also impact your final potency.
Cannabis Flower Buds
Cannabis buds, or flowers, will make a more potent butter than trim or leaves and exert stronger effects because the flower contains a higher concentration of cannabinoids.
Keep track of how many grams of weed you add to the butter so you can calculate the final potency of your cannabutter in mg THC (or CBD, CBG, etc).
How much flower you use is a personal preference and will dictate how potent your final batch of cannabutter is. Remember, the better the bud, the better the butter š
Shake, Trim, or Leaves
Using all parts of the cannabis plant is great for sustainability, and many people exclusively make their cannabutter with shake, trim, or leaves from the raw cannabis plant.
Because trim leaves do not contain nearly as many cannabinoids as flower buds, you may want to use more, up to 50% more by weight.
Also keep in mind that trim and leaves contain more chlorophyll, and will result in a more green-colored final product.
Kief
Kief is the fine, powdery substance that accumulates at the bottom of a hand grinder.
It typically contains the most cannabinoids and trichomes.
This means it will make a very strong butter, depending on your tolerance level.
Because kief is more potent than bud, you may be able to use less of it in this recipe, depending on the effect you're looking for. It is also a great option to use if you have a high tolerance.
Just remember that you still need to decarb kief.
If you've never worked with kief before, you can get my guide on decarbing kief and my guide for making homemade kief butter.
Concentrates
You can use cannabis concentrates like distillate or FECO to quickly and easily make a very potent cannabutter. These products are great because they state the milligrams of THC on the package, making dosing easy.
The most important thing is to decide how much or how little butter you want to use, as this will affect the final potency. Then warm the butter up in a small saucepan, stir in the concentrate, and mix well.
To Make A More Potent Cannabis Butter:
- Choose a higher-quality flower that contains more % THC, CBD, etc
- Add decarbed kief or cannabis concentrates like distillate or FECO
- Make kief cannabutter
- Use more flowers (increase from 1 ounce to 2 ounces or more)
- Use less butter (decrease from 1 pound of butter to Ā½ pound)
Frequently Asked Questions
While it's a simple recipe, here are the questions I get asked most frequently from my Well With Cannabis Community to help you make the best cannabutter possible.
Using a crockpot is the best method for a set-it-and-forget-it, basic recipe option, but you can also use the sous vide method with an immersion circulator or Instant Pot.
Butter is perfect for making homemade edibles because of its high-fat content. It is versatile and can be used in many recipes, rangingĀ from sweet to savory dishes. Cannabinoids are lipophilic, meaning that they dissolve in and bind to fat. When cannabinoids are extracted with fat, they are more easily absorbed and thus more bioavailable in our bodies (1).
I prefer using Kerrygold unsalted butter because it has a higher butterfat content, meaning more opportunity for cannabinoid infusion and fewer impurities to remove. You can also use clarified butter or ghee, which will save you a step in the end. Ghee is butter that has already been clarified or has had the milk solids removed. If you want to clarify your butter ahead of time, gently boil the butter in a saucepan over the stove and skim all the foam, or milk solids, from the top. Do NOT use margarine or other types of āfakeā butter.
If you do not clarify your butter first, you will notice white particles on your cooked butter the next day. They are simply milk solids. These solids will be removed when you strain and discard the excess water.
You should expect a volume loss of 15-25%. This occurs due to the removal of the milk solids and evaporation of excess water. Volume loss is important to keep in mind, especially if you try to make a small batch to use in a particular recipe.
Place a heavy heat and water-safe item on the jar's top to weigh it down; a clean rock works well. Also, there can be an occasional mishap that results in a broken or cracked jar - it happens to the best of us without rhyme or reason. To help prevent this, use a mason jar specifically meant for canning or cooking. Do not use leftover glass jars from other products. Also, use a brand new lid so you know the seal is good and the contents inside will stay dry.
No. Color doesnāt have any correlation with potency. A very green butter is simply cannabis butter with a lot of chlorophyll, the green pigment that has also been extracted from the plant. You will have a deeper green color if you use trim or very fresh buds.

Peggy
can you take cannabutter out of freezer and re make it to make it stronger I made a few batches with shake but now I have a good lot of bud and would like to redo it by adding the cannabuttre to the water and creboxelated weed and recook it
Emily Kyle
Yes, Peggy, you can re-infuse to try and make it stronger. Good luck š
Nina
What size mason jars did you use?
Emily Kyle
Nina, I used pint-sized mason jars š
Melody
I have a very small crockpot that will only hold one 1 cup mason jar, so I'm gonna cut out the jar and just use straight crock pot. We'll see how it goes!!!;
Emily Kyle
Good luck, Melody, it should be just fine. Let us know how it turns out š
Sarah
Can I used pre-decarbed bud from vaping?
Emily Kyle
Yes, you can, Sarah! Here is a full guide for making edibles with already vaped bud - if you need it š
Barb
I did this last weekend and made chocolate kringle cookies. I was afraid there would be a weird taste but my Hubby said he didn't taste anything other than the cookies. I was pleasantly surprised that it worked so well.
Emily Kyle
I am so glad you had such a great experience, Barb! Thanks for letting us know š
Sum
I tried this recipe and Iām mind blown!! I followed every step and used 3.5 grams of cannabis.
After decarboxylating the weed at 250 degrees for 25 minutes, i put it in an old pickle jar with 1 stick of butter. I placed the jar in water in a pot on the stove and for 4 hours, I monitored the water making sure it stayed between 180 -190 degrees.
I used the cannabutter to make rice crispy treats. About 90 min later I felt high, about 2 hrs later I was in another dimension.
Great Recipe!!! Thanks so much!!
Emily Kyle
I am so happy you enjoyed this recipe, Sum, thanks so much for letting us know how your experience went š
Sam
Hi Emily,
I used this recipe to infuse 3.5 grams of flower with 1/2 cup of butter. Which I then used in a boxed cookie mix. The boxed recipe called for 1/2 cup of butter, so I used my whole infused batch. Based on your calculator, each cookie should have about 21mg of THC. My issue is that that have a VERY strong weed flavor. Is this due to the potency or could I have made a mistake to cause such a strong flavor?
Thanks for all the great info and recipes!
Emily Kyle
Hey Sam! Thanks for the kind words. The flavor is not related to potency, or process, but rather the amount of chlorophyll and terpenes that have made their way into your infusion. You can read more about chlorophyll and how to reduce the flavor here.
Scroller49
Iād like to know the proportion of cannabis to butter, ratio.
Say 1 cup of butter, should I use 2 oz of decarbolyzed bud, cook them up together to make the butter for my MJ cookies?
Bjƶrn
Can I skip the step of removing water? Making cookies and I usually add water anyway, figured I could just leave it in?
Emily Kyle
Yes Bjƶrn - I don't see why not š
Emily Kyle
Hey Scroller49 - This Flower to Oil Ratio Guide will help you determine how much to use š
Anne
I am new to this. I have medical THC liquid and I want to use it in ghee. I have 1 gram vials. Please advise proportions.
Emily Kyle
Hello Anne. Does your vial state how many mg of THC are in each one? That would be helpful to know because then you can do the math from there. Then you will want to know what you're going to be making and how strong you want it to be. For example, if you want to make brownies with 10mg THC each, and one vial contained 1,000mg - you would want to use 1/10th of your vial. I hope that makes sense!
Anne
It says THC 84.6 percent
CBD .809 percent
THC 951.690 mg CBD 9.100 mg
I put the butter on toast. I want it to help pain of arthritis and neuropathy.
Emily Kyle
This means the entire syringe contains 952mg of THC. Have you ever had THC before? Do you know how much you want to aim for per serving? If not, I would say that 5mg of THC is a good place to start. If youāre putting butter on toast, let's say youāre doing 1/2 teaspoon per serving. There are 48 teaspoons in 1/2 cup of ghee. 48 teaspoons = 48 servings. 48 servings at 5mg each would be 240mg. Your whole syringe contains 952/240 = 3.9 so this means you would want to use approximately 1/4 of the syringe. If it is already labeled with measurements, it should be easy to do. Following this math, you can adjust the servings and how much butter you need to get the perfect ratio. I hope this helps! I emailed you, as well.
