Chocolate Peanut Butter Cookies

1 stick butter, softened
1/2 c. creamy peanut butter
3/4 c. sugar
6 Tbsp. firmly packed brown sugar
1 egg
1 tsp. vanilla
2 (1oz) squares unsweetened chocolate, melted
1 1/3 c. flour
1/2 tsp. baking powder
1/2 tsp. baking soda
1/2 tsp. salt

In a medium bowl, beat butter and peanut butter with an electric mixer on medium speed until creamy. Add sugar and brown sugar and beat until blended. Beat in egg, vanilla, and melted chocolate until well blended. Add flour mixed with baking powder, baking soda, and salt and beat until well blended. Cover and refrigerate until firm, about 30 minutes. Preheat oven to 350*. Shape dough into 1 inch balls and place 1 inch apart on greased cookie sheets. Flatten with a fork. Bake 10-12 minutes, or until cookies are set. Let cool on sheets 2 minutes, then remove to a rack and let cool completely.

Makes about 48 cookies.
