Step #1: The Decarb Process

Prep Time: 15 min. ll Bake Time: 30-40 min.

Note: Before making CannaButter, you must first go through the decarb process. Decarboxylation occurs when there is a reaction which separates molecule groups, turning THCA (non-active) into THC (the happy stuff). This is why you must heat the bud at a low temp. Without it, there would be no psychoactive properties. This is true when you smoke, too!


  • 1/2 ounce to 1 or more ounces of shake, popcorn, and/or trimmings


  • grinder 
  • parchment or aluminum foil 
  • spatula or flipper 
  • baking sheet 
  • oven set to 220°F


  • For stronger concentrate, use 1 oz. cannabis to 1 lb. butter 
  • For weaker concentrate, use 1/2 oz. cannabis to 1 lb. butter

  1. Collect as much shake, popcorn, or trimmings as desired, & grind in order to maximize surface area. There’s no need to use the “good stuff.”
  2. Place parchment or aluminum foil on a baking sheet, then spread your cannabis over the top. 
  3. Bake at 220°F for 25-40 minutes, stirring several times. Baking times will vary.
