Ingredients

1/2 cup butter, softened
1/2 cup sugar
1/2 cup brown sugar
1/2 cup peanut butter
1 egg
1 1/4 cups flour
1/2 teaspoon baking soda
1/2 teaspoon salt
6-ounce package semisweet chocolate chips

Directions

Cream together butter, sugars and peanut butter in medium bowl. Add egg and beat until fluffy. Stir in flour, baking soda and salt.

Roll dough into an oval shape about 1/4-inch thick on sheet of wax paper; set aside. Melt chocolate chips slowly in top of double boiler; cool slightly and spread thinly over dough with spatula. Starting with long end, roll up dough and wrap tightly in plastic wrap; chill for several hours or freeze until ready to bake. Preheat oven to 375 F. Slice dough 1/4-inch thick and place on ungreased cookie sheets. Bake for 12 minutes. Let cool on wire racks.
