Yield 16 bars


  • 1/2 cup butter melted
  • 2 cups graham cracker crumbs
  • 2 cups powdered sugar
  • cups peanut butter
  • 8-12 ounces marshmallow fluff
  • 1 1/2 cups semi-sweet chocolate chips

  1. Mix butter, graham cracker crumbs, powdered sugar, and peanut butter together until completely combined.
  2. Press into the bottom of a 9×13 baking dish.
  3. Spread a layer marshmallow fluff over the graham cracker crust. It's a little tricky but it will spread.
  4. Melt the chocolate chips in the microwave in 30 second increments stirring in between until melted. Pour over fluff layer and spread gently.
  5. Sprinkle peanut butter cups on top and press down gently.
  6. Refrigerate bars until set for 30-60 minutes.
  7. Cut into bars and serve. Store bars in the fridge. They will soften at room temperature.
