1 1/4 c. butter, softened
2 c. sugar
2 eggs
2 tsp. vanilla extract
2 c. all purpose flour
3/4 c. Hershey's cocoa
1 tsp. baking soda
1/2 tsp. salt
2 c. Reese's peanut butter chips or Hershey's semi-sweet chocolate chips

Heat oven to 350 degrees. In a large mixing bowl cream butter and sugar until light and fluffy. Add eggs and vanilla; beat well. Combine flour, cocoa, baking soda and salt; gradually blend. Stir in baking chips. Drop onto ungreased baking sheet. Bake about 9 minutes; do not over bake. Cookies will be soft. They will puff while baking and flatten while cooling.

Makes about 4 1/2 dozen.
