Peanut Butter Bar Instructions
Preheat oven to 325 degrees. Combine eggs, sugars, peanut butter, butter, and vanilla until fluffy. In a separate bowl, combine flour, baking powder, and salt. Add flour mixture to peanut butter mixture and stir just until combined. Spread into a lightly greased 9 x 13 pan. Bake for 25 minutes. Remove and allow to cool.
Chocolate Frosting Instructions
Combine powdered sugar, butter, vanilla, and cocoa until well blended. Add milk a few drops at a time until frosting is a spreadable consistency. Add more powdered sugar if your frosting gets too runny.
Spread frosting over cooled peanut butter bars. Crumble Reese's peanut butter cups all over the top of the pan. Cut and serve!
