Reese’s Treat Bars

Course: Desserts
Servings: 15 bars
Author: Denise


  • 8 Tbsp unsalted butter
  • 12 oz large marshmallows
  • 1/2 cup mini marshmallows
  • 8 cups mini Reese’s Peanut Butter cereal
  • 1/2 cup mini Reeses’s candy roughly chopped


  • Line a 13 x 9 pan with parchment paper. Set aside.
  • Next, melt butter in a large pot over medium high heat until the butter is just about melted. Note, I think a nonstick pot works great!
  • Turn heat down to medium low and add large marshmallows. Stir frequently until just about melted and almost smooth.
  • Remove the marshmallow mixture from the heat and pour in Reese’s cereal. Stir with a wooden spoon or rubber spatula until the cereal is completely covered in the melted marshmallows.
  • Pour half of your mixture into your pan. Use your spatula or wooden spoon to press down. Sprinkle mini marshmallows over top. Add half of the chopped mini Reese’s cups.
  • Top with remaining cereal and marshmallow mixture. Again, use your hands or spatula to press down. Note, spraying your hands with nonstick cooking spray can help.
  • Garnish with remaining chopped mini Reese’s cups.
  • Leave uncovered or cover with plastic wrap and let sit on the counter for at least 1 hour before cutting and enjoying.
