Reese’s Chewy Chocolate Cookies

2 cups all-purpose flour

3/4 cup Hershey’s Cocoa
1 teaspoon baking soda
1/2 teaspoon salt
1-1/4 cups (2-1/2 sticks) butter or margarine, softened
2 cups sugar
2 eggs
2 teaspoons vanilla extract
1-2/3 cups (10-oz. pkg.) Reese’s Peanut Butter Chips

Heat oven to 350°F. Stir together flour cocoa, baking soda, and salt. In large bowl, beat butter and sugar with electric mixer until light and fluffy. Add eggs and vanilla; beat well. Gradually add flour mixture, beating well. Stir in peanut butter chips. Drop by rounded teaspoons onto ungreased cookie sheet. Bake for 8 to 9 minutes. (Do not over bake; cookies will be soft. They will puff while baking and flatten while cooling.) Cool slightly; remove from cookie sheet to wire rack. Cool completely. This makes about 4-1/2 dozen cookies.
