Instructions

1. In a large mixing bowl whisk together the flour, sugar, baking powder and salt.
2. Combine the peanut butter, butter, milk, vanilla and eggs, stirring well.
3. Add the peanut butter mixture to flour mixture; stir until combined.
4. Stir in chocolate chips. Pour into a prepared baking pan (I used a 9x13, but you could do 8x8 or 9x9 for thicker bars).
5. Top with chopped peanut butter cups and bake at 350º for 30-35 minutes or until your tester comes out clean.
