¾ tsp baking soda
½ tsp baking powder
¼ salt
½ cup butter, softened
1 cup peanut butter¾ cup sugar
½ cup firmly packed light brown sugar
1 large egg
1 Tbsp milk
1 tsp vanilla
½ cup peanut butter chips
½ cup chocolate chips
Sugar in a bowl for dipping

Preheat oven 350 degreesIn a large bowl, combine the flour, the baking soda, and the baking powder, and the salt. Set aside.In a large bowl, beat the butter and the peanut butter together until fluffy. Add the sugars and beat until smooth. Add the egg and mix well. Add the milk and the vanilla. Add the flour mixture and beat thoroughly. Stir in the peanut butter chips and chocolate chips. Drop Tbsp size rounded cookie dough into bowl of sugar to coat. Place on ungreased cookie sheet leaving several inches between for expansion. Slightly flatten cookies with back of fork. Bake for 10-12 minutes. The cookies will look underdone. Cool for 1 minute on pan then remove to a rack to cool completely. These are DELICIOUS.. and can be blamed for my recent 3lb. weight gain.
