1-1/4 cups butter or margarine
2 cups sugar
2 eggs
2 teaspoons vanilla
2 cups unsifted flour
3/4 cup cocoa
1 teaspoon salt
2 cups Reese's peanut butter chips

Cream butter or margarine 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 for 8-9 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.
