Instructions

  • Spray a 9"x 13" pan with nonstick cooking spray and set aside. 
  • Put your white chocolate into a microwave safe bowl and microwave for about 20-30 seconds. Stir, then microwave again for another 20-30 seconds. Continue to microwave for 20-30 seconds at a time, stirring in between, until your chocolate is fully melted but not too hot. Set aside.
  • In a large and deep nonstick pot, melt the butter. Add the karo syrup and sugar and stir until the mixture comes to a boil.  Boil for 1 minute, then reduce the heat to low and mix in the peanut butter and marshmallows.  Keep stirring until the mixture comes to a boil again.
  • Remove from the heat and stir in the Reese's Puffs Cereal until well combined. Pour cereal mixture into your prepared baking dish and spread evenly with a spatula.
  • Sprinkle the chopped Reese's Peanut Butter Cups on the cereal bars and then drizzle with the melted white chocolate.
  • Let sit for at least 20 minutes until the Reese's Puffs Cereal bars are cooled and the chocolate on top has set.
  • Once you are ready to serve, cut into 3" squares and enjoy!
