How to make Cannabis Butter The way to Edibles (Part 2)

What is cannabutter?

Cannabis-infused butter, or cannabutter, is one of the simplest and most common ways to make edibles. Butter is an ideal medium for cannabis infusion because it’s delicious, versatile to use, and THC needs to bind to fat molecules, which are abundant in butter (as well as oils such as coconut, olive, and vegetable oil).

The infusion process takes a few hours, but it’s easy to do and this recipe will show even beginners how to do it.

As with all edibles, start low and go slow: After making food with weed butter, try a little bit first, wait 45-60 minutes for effects to kick in, and have more only if you want stronger effects.

How is cannabutter used to make edibles?

After you infuse butter with cannabis, you can use that weed butter to make any baked goods, or to simply spread on some toast or other food. People commonly use cannabutter to make weed brownies, cookies, and cakes.

You can use all cannabutter in a recipe, half cannabutter and half regular butter, or some other ratio of regular to cannabutter for milder effects.

Cannabis must first be decarboxylated to properly infuse it with butter. This process converts THCA in the plant into THC, activating the plant’s psychoactive potential in your edibles.

Heat is needed for decarboxylation. When you put a flame to a bowl or joint, that heat decarboxylates the plant material, turning THCA into THC, which will then get you stoned. For cannabutter, decarboxylation is done by heating cannabis at a low temperature in an oven before adding it to the butter.

Note that homemade edibles are difficult to accurately dose. This guide will give you some tips for dosing, but all DIY cannabis cooks should be aware that it’s difficult to guarantee the potency or homogeneity of a batch of edibles.

Why decarboxylation is necessary for making cannabutter

Before making cannabutter, you need to decarboxylate, or “decarb,” the cannabis flower. Skipping this step will result in butter that has little to no cannabis effects.

As mentioned above, decarboxylation converts THCA into THC using heat, which will allow the butter to have THC and deliver euphoric effects.

Some recipes call for putting cannabis directly in hot butter, but decarbing before will make your cannabutter more effective, and the less time spent soaking buds, the better your infused butter will taste. For this reason, we recommend decarbing in an oven first.


  • Baking sheet

  • Parchment paper

  • Oven

  • Saucepan, stock pot, double-boiler, or slow cooker

  • Mesh strainer or cheesecloth

  • Container for cannabutter

  • Cannabis grinder (optional)


  • 1 cup unsalted butter (230g)

  • 1 cup water

  • 1 cup ground cannabis (7-10 g), decarboxylated

When making cannabutter, we recommend a 1:1 ratio of cannabis to butter. If you want milder effects, use less cannabis.

Basic cannabutter recipe

  1. Decarb the cannabis. Preheat the oven to 120ºC. Cover the baking sheet with parchment paper and place the loosely broken up cannabis on it. Heat in the oven for 30-40 minutes. Gently mix the buds every 10-15 minutes to expose all sides of the buds. (Older, drier cannabis may require less time.) Tip: You can also set your oven to 150ºC and heat for 10-15 minutes, although the low-and-slow approach is recommended to better preserve cannabinoids and terpenes.

  2. Grind or break up the cannabis. Grinders break weed down to the same consistency and will save you time, but you can just as easily break up the weed with your hands. Keep in mind that anything small enough to fit through the mesh strainer or cheesecloth will end up in your finished product, so be careful not to grind the weed into a fine powder.

  3. Melt the butter. On low heat, melt 1 cup of butter in a saucepan, stock pot, double-boiler, or slow cooker. Add 1 cup of water, which will help regulate temperature and prevent the butter from scorching.

  4. Add the cannabis. After the butter is fully melted, add in the decarbed cannabis.

  5. Simmer. Simmer on low heat, between 70-90ºC; don’t exceed 90ºC or you may burn out the cannabinoids. Simmer for 2-3 hours, stirring occasionally. The mixture should never come to a full boil.

  6. Strain the mixture. Place a mesh strainer or cheesecloth over a jar and pour the butter/cannabis mixture through it. Discard the plant material. Tip: Don’t squeeze out every bit of butter—this will add chlorophyll to your cannabutter, giving it a bad plant taste.

  7. Refrigerate. Place the jar of butter in a fridge, and let it solidify before using, ideally overnight, or a few hours at least. If excess water forms at the bottom of the jar, remove the solid butter with a knife and drain out the water.
