Directions:

Cream together butter, peanut butter and sugars. Beat in eggs.

In a separate bowl, sift together flour, baking powder, baking soda and salt. Stir into batter. Put batter in refrigerator for 1 hour.

Roll into 1-inch balls and put on baking sheets. Flatten each ball with a fork, making a criss-cross pattern. Bake in a preheated 375 degree F. oven for about 10 minutes or until cookies begin to brown. Do not overbake.
