  • 9x9 inch pan



  • In a large pot, melt butter over medium heat.
  • Add marshmallows and turn heat to low.
  • Stir until completely smooth.
  • Remove from heat and quickly stir in peanut butter.
  • Add cereal.
  • Fold in the mini marshmallows.
  • Pour Krispies treats into a 9 inch square baking dish lined with parchment paper (or buttered foil). DO NOT PRESS them in tightly. Just very gently even the top of the treats (use the butter wrapper to press it in).
  • Top the melted peanut butter morsels with the peanut butter cups. Press those in so they stick!
  • Allow to set, about one hour.
  • Cut into squares and store in an airtight container.
