1/2 c Butter
1/2 c Peanut Butter
1/2 c Sugar
1/2 c packed Brown Sugar
1 Egg
1 1/4 c Flour
1/2 tsp Baking Powder
3/4 tsp Soda
1/4 tsp Salt

Mix butter, peanut butter, sugars and egg. Add dry ingredients. Blend. Chill dough.

Add chocolate chips to mix before baking to make it chocolaty, or melt 2 1-ounce squares unsweetened chocolate with the 1/2 c butter required by the recipe.
