How to Decarb Weed

First, the THC in weed cakes must first go through a process known as decarboxylation. Decarbing weed activates the THC in cannabis. So if you still need to decarb your weed, you can follow the steps in our comprehensive guide on how to make cannabutter.

It is recommended for those relatively new to cannabis or with a lower tolerance to use 1/4 of decarbed cannabis buds or 1/2 cup of cannabutter. On the other hand, seasoned stoners could easily make a much more potent cannabis cake using a full cup of cannabutter in substitution of butter or oil. Alternatively, you could add up to a full ounce of decarbed cannabis flower, although cannabutter will provide a much better flavor.

Be sure to exercise caution with the dosage. Since the liver converts the THC in edibles like cakes, cookies and gummies into a much stronger form, the high is much more potent than smoking. There’s nothing worse than eating too many edibles, after all. And if you’re making this for a party, not everyone will have the same tolerance so best to start with lower amounts. Naturally, it’s also harder to stop at just one slice of cake.

How to Make Weed Cake

You can make your cake from scratch, but it can feel like a lot of work, and there are box cake options that are off the hook! Our advice, get your favorite box cake mix and follow the directions. Betty Crocker Super Moist boxed cake mixes are a fan favorite in the cannabis community. And thankfully they come in a wide variety of flavors for your infusion pleasure!

The only deviation from the directions will be to add weed. Once your weed has been decarbed, run it through a coffee grinder to turn it into a powder. This will help it mix better with the other ingredients. Also, using real butter and or MCT oil will improve the consistency and taste.

Mix all your ingredients, including your decarbed weed, and bake. Once your weed cake is ready, let it cool thoroughly and add the final touch, frosting.
