1 1/4 c. butter, softened
2 c. sugar
2 eggs
2 tsp. vanilla
2 c. unsifted all-purpose flour
3/4 c. Hershey's cocoa
1 tsp. baking soda
1/2 tsp. salt
2 c. (12 oz. pkg.) Reese's Peanut Butter Chips

Cream butter and sugar. Add eggs and vanilla, beat well. Combine flour, cocoa, baking soda and salt. Gradually blend into creamed mixture. Stir in chips.

Drop by teaspoonfuls onto ungreased cookie sheet. Bake at 350 degrees for 8 to 9 minutes. Do not overbake. Cookies will be soft; they will puff while baking and flatten while cooling. Cool slightly. Remove from cookie sheet. Makes about 4 1/2 dozen.
