  • 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.

  • 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!
