1 stick butter, melted
4 tbsp. cocoa
1 c. sugar
1/2 c. flour
2 eggs
1 tsp. vanilla
1 c. chopped nuts

Mix butter and cocoa; cook just a little. Add other ingredients. Pour into 8 x 8 inch pan and bake 20 minutes at 350 degrees.

I usually mix a little cream cheese, cocoa, powdered sugar, and vanilla for frosting.
