A perfectly-rolled joint is splendid, but cannabis edibles can be truly divine. Making your own cannabis butter (“cannabutter”) is a perfect way to always be able to whip up a quick batch of edibles, or just dip a spoonful in your tea when it’s time to hit the couch and coast away. Many patients also prefer edibles over smoking.

Cannabutter is easy to make and can be stored in the refrigerator, making infused butter an ideal and convenient ingredient to have on hand requiring nothing more than just popping open the container and spooning out what you need. It is also perfect for making what is arguably the most iconic edible of all — the “pot brownie.”

All it takes is just adding cannabutter or oil to the brownie recipe of your choosing, but you can also make marijuana cupcakes, a birthday cake to remember (or forget, at least in the short term), a magical pan of perfectly seasoned cannabis spaghetti sauce, or even lobster bisque.

  • Fill your crock pot about halfway full of water. Turn the crock pot on and let it heat to 160-190°F (70-90°C). Using a laser thermometer can aid with temperatures.
  • Cut the butter into cubes and add to your mason jars. Add the decarbed cannabis into the mason jars and cover. (If you want to reduce the smell while cooking, add tight-fitting lids to the jars.)
  • Put the jars into the water inside the crock pot and secure the lid on the crock pot. Cook for at least 2 hours. Be sure to stir and burp the jars after an hour of cooking. You can let it cook for up to 4 hours. Just check on it and stir hourly.
  • When you’re ready, carefully remove the jars from the crock pot and let them cool for a few minutes.
  • Using a strainer and cheesecloth, strain the mixture.
  • Place the cannabutter into your storage container and put it in the fridge until it hardens up.

You now have infused butter you can use for many recipes!

Chef Jordan’s tips

Add aromatics to your infusions to add different flavor profiles; fresh vanilla or lemon zest for sweet infusions or thyme, mint and rosemary for savory.

Method 2 — Saucepan:

(For this method, in addition to the ingredients listed above, you will need 1 cup of water and a saucepan.)

To make cannabis butter in a saucepan, simmer 1 cup of water and 1 cup of butter until the butter melts. As the mixture simmers, add in the decarboxylated cannabis and stir well. Keep at a low heat and let simmer for 2-3 hours, stirring occasionally, keeping the heat around 160-180°F (70-80°C), making sure not to let it come to a boil. 

After 2-3 hours, take the pan off the heat and after it cools down, strain it through the cheesecloth into a container. 

You can also make it in a crockpot or infuser. Just set the temperature to around 160-180°F (70-80°C), add in the cup of butter and half ounce of decarboxylated cannabis, stir it and cover the crockpot. Let simmer for about three hours, stirring occasionally. 

After the butter has cooled, strain through a cheesecloth into the container.

How much cannabis should I use for cannabutter?

How much cannabis you should use for your cannabutter depends on how strong you want it to be. For your first batch, you may want to consider starting with a more modest amount. Once it’s ready, try a very small amount — on a cracker or stirred into some tea — and wait a couple of hours and see what you think. Don’t get impatient, as edibles can take up to two hours to kick in.

If you’re using ½ ounce of cannabis that is 14% THC using the above recipe, each teaspoon of butter will contain roughly 40mg of THC. 

If you’re using ¼ ounce of cannabis that is 14% THC using the above recipe, each teaspoon of butter will contain roughly 20mg of THC.

You can also use an online edible dosing calculator to estimate the strength of your butter.

Common mistakes when making cannabis infusions 

The first mistake people make when making cannabutter is to skip the decarboxylation step. This means you’ll end up making a weaker batch that won’t work nearly as well, and won’t absorb into the butter as well either. 

You also probably want to avoid using your top-shelf flower. Because the long cooking/infusion process absorbs so much of the flower’s THC and a rich assortment of cannabinoids, terpenes, and flavonoids, you can make a great cannabutter even with marijuana that you probably wouldn’t write home about. You can even get by supplementing the bud with shake and already vaped marijuana flower. 

Since you’re cooking butter on the stove for hours on end — pay attention. Make sure to stir occasionally and keep a watchful eye on the pot so it doesn’t burn.
And, as with all edibles, start low and go slow. You can always eat more if it’s not strong enough. If you do take too much, here are some tips for what to do if you get too high.

Why does marijuana need a fat?

The cannabinoids in cannabis — including THC and CBDare fat-soluble and must be eaten with fat in order to be broken down by the body. When making a batch of cannabutter, the butter soaks up the THC and other cannabinoids, as well as terpenes and flavonoids, creating a powerful butter infusion. 

What’s decarboxylation?

One thing you don’t want to forget — but you wouldn’t be the first person to do so — is to decarboxylate your cannabis. 

Decarboxylation refers to a process that activates compounds in cannabis — most notably, THC, which is transformed during decarboxylation from the non-psychotropic THCA to THC, which creates the high that marijuana is known for.  

The easiest way is to decarboxylate is to heat the cannabis, typically in an oven set to around 220-245°F (105-120°C) degrees fahrenheit for about 30-45 minutes, paying careful attention that the oven isn’t too hot.
