No-Bake Peanut Butter Cup Bars


  • 1 cup brown sugar
  • 1 3/4 cups powdered sugar
  • 3/4 cup (1 1/2 sticks) unsalted butter, softened, divided
  • 1 1/2 cups creamy peanut butter
  • 1 1/2 cups semi-sweet chocolate chips


  1. Grease an 8-inch square pan with butter or nonstick spray. Set aside.
  2. In a large bowl, cream together 1/4 cup (1/2 stick) of the butter, brown sugar, and powdered sugar with an electric mixer until smooth.
  3. Add peanut butter and beat until smooth. Press mixture into prepared pan.
  4. Add chocolate chips and remaining butter (1/2 cup/1 stick) to a small bowl. Heat in microwave at 30 second intervals, stirring in between, until melted. Pour over peanut butter mixture and spread out evenly with a rubber spatula.
