2 sticks of unsalted butter 1/2 ounce of marijuana (ground and with seeds/stems removed) 1 cup of water

To set up a double boiler, place a large stock pot on your stove and fill it about 1/3 of the way full with water. Then, place a medium sized bowl over the stockpot. The bowl should be large enough to overlap the edges of the stock pot, but small enough so that the bottom of the bowl will be in or near the water. Heating cannabis is necessary to extract the THC and reap the psychoactive effects of the herb. You cannot digest the THC in raw marijuana, so eating raw marijuana would have no effect.

Keep the heat low. Do not allow the butter to come to a boil. The THC in cannabis is fat soluble, not water soluble. This means that it is necessary to heat the cannabis in butter or oil to capture the THC for use in baking. If you do not eat dairy and do not want to use butter, then you could use some non-dairy margarine or coconut oil instead.

Fold over the shorter edges of the cheese cloth first. Then fold over one of the long edges and roll the marijuana towards the other edge, as if you are rolling a burrito. Use the cooking twine to tie up the burrito. Make sure that you wrap the string around the burrito evenly and secure it well or it might fall apart.

Remember that the THC in marijuana is fat soluble, not water soluble. That means that water alone will not extract much of the THC from your marijuana. The water will just help to heat the marijuana so that the THC can be absorbed by the fat in the butter.

If you do not want the cannabutter to have too much THC in it, then you might want to stop steeping it at around three to four hours. However, if you want it to be strong, then let it steep for a full six hours.

You may also want to use a second metal spoon to press the marijuana tea bag and squeeze out any excess liquid from the teabag back into the bowl.

You can leave the butter in the fridge for a few hours or overnight. If you transfer the liquid to a foil pan, then you can easily drain away the water after it cools.

Pour out the water and keep the butter. You can use a strainer or just punch a hole in the bottom of your foil pan if you transferred the butter. The butter is now ready to use to make chocolate chip cookies or as a one to one substitute for regular butter in your favorite cookie recipe. For example, if the recipe calls for ½ cup of butter, then replace the butter with ½ cup of cannabutter.

Make sure that the cannabutter is at room temperature before you start mixing the cannabutter and sugar.

For large cookies, scoop ¼ cup of dough at a time onto the cookie sheet. If you want smaller cookies, then try adding one tablespoon at a time onto the cookie sheet.

For larger cookies, bake the cookies at 325 degrees for 18 to 25 minutes. Closer to 18 minutes will result in a chewier cookies, while closer to 25 minutes will result in a crunchier cookie.
