There are many ways to make cannabutter and this cannabutter slow cooker method is probably the easiest but this method lacks a decarb process which means some of the THC is left behind in the form of THCa (a non-psychoactive form of the drug found in raw marijuana).
I strongly recommend you also add a decarbing process before putting your cannabis in the slow cooker. You can always use AVB bud (Already Vaped Bud). I have included the decarbing method at the bottom of the article, it is not essential but will yield a much stronger cannabutter. Remember to start cooking the day before you want to use your cannabutter because this method takes 12-24 hours.
The cannabutter slow cooker method!
You can make cannabutter with any kind of cannabis, but if you’re going to make cannabutter you might as well make a decent batch with some high-quality cannabis. So source some top quality bud in advance.
For the cannabutter slow cooker method you will need to grind up one ounce of cannabis (around 30g), the finer the better. If you have a spare coffee grinder or herb grinder you can use that. (Just don’t put that grinder back into regular use afterwards. It might make for a fun morning but might not go down so well with your boss).
If you don’t have a grinder, get to work with a pair of scissors and a sharp knife. Once you have a fine grind toss it into your slow cooker with a cup of water and a pound of unsalted butter (around 450g). Turn your slow cooker to low, and whack the lid on. Leave it for at least 12 hours, but you can leave it up to 24 hours, the longer the better.
While you don’t technically need to stir this recipe, giving it a quick whirl whenever you are walking past will ensure that you get a good result and you can check if the pot is looking a little dry, you can add more water if need be.
When your butter has finished cooking (or you have finished waiting!) you’ll need a glass container to store it in, a strainer, and a layer of clean cloth like cheese cloth, or an old clean t-shirt. Pop the strainer over the glass container, line with fabric and pour the butter through it. Squeeze out all of the liquid and separate the herbs (don’t skip this step, there are heaps of cannabinoids in this liquid) and throw away the waste plant materials.
Place your butter in the fridge for a few hours. Once it has fully hardened you will be able to lift the butter out of the water. Discard the water and store the butter in a sealed container.
You’re ready to start cooking!
A word of warning, don’t microwave your butter to soften it, this will cause you to lose some of the cannabinoids you’ve worked so hard (or not so hard!) to collect.
Sounds trickier than I promised? It’s just a few quick steps: butter, buds and water in the slow cooker, strain and chill in the fridge. It takes a bit of time, but absolutely no effort!

How to decarb cannabis
Decarb, decarbing or it’s correct term Decarboxylation is the process of heating your cannabis which causes a chemical reaction and starts to convert THCa into THC. The boiling temperature of THC is 314ºF which means if you heat your cannabis too much you will convert the THC to CBN or destroy it. THCa is the non-psychoactive form of the drug found in raw marijuana when heated it turns into the psychoactive drug we love THC.
Heating your cannabis to 240ºF for one hour is the recommend process for decarbing cannabis. This will prepare the cannabis for a more potent cannabutter. Place raw cannabis on a baking sheet on a baking tray and place it in an oven for one hour.
