1 1/4 c. butter, softened
2 c. sugar
2 eggs
2 tsp. vanilla extract
2 c. flour
3/4 c. cocoa
1 tsp. baking soda
1/2 tsp. salt
2 c. (12 oz.) pkg. peanut butter chips or semi-sweet chocolate chips

Heat oven to 350 degrees. In large mixer bowl cream butter and sugar until light and fluffy. Add eggs and vanilla; beat well. Combine flour, cocoa, baking soda and salt. Gradually blend into creamed mixture. Stir in peanut butter or chocolate chips. Drop by teaspoonfuls onto greased cookie sheet.

Bake 8-9 minutes. Do not over bake; cookies will be soft. They will puff while baking and flatten while cooling. Cool completely on wire rack.
