For mostly all recipes need a certain amount of "weed butter", which is then used like ordinary butter. THC will not react to a water-soluble compound, so butter would be a good carrier for ingestion.

Melt a pound of butter in a pan. Mix about 60-70 grams of  thoughly sifted weed into it. Let it cook until the butter has a green color. Then squeeze the butter through a strain but keep the leaves away with a fork. Squeeze hard to get the butter out. Cooking may vary from what temperature you may have it on

2 Eggs

3/4 cup of sugar

1 tablespoon vanilla

1/2 cup of weed butter melted

3/4 cup Choclate; ground

2/3 cup unsifted flour

1/4 tablespoon baking powder

1/4 tablespoon salt

1/2 cup walnuts; chopped (optional)

Heat oven to 350 degrees F. Using a spoon, stir in eggs with vanilla and sugar; add butter. Sift ground choclate with flour, baking powder and salt. Stir into egg mixture; add nuts. Spread into greased 8 or 9 inche square pan. Bake at 350 degress F for 20-30 minutes. For more chewyness bake in 8 inch pan and less baking time. Cut into squares. Eat in moderation. It might take 15 minutes to several hours for it to work. I recomend  not eating anything for 2-3 hours
