Ingredients

Scale

Main Ingredients

  • 8 cups mini marshmallows (from 16 oz bag)
  • 8 tablespoons unsalted butter
  • 1/2 cup creamy peanut butter
  • 7 cups plain Rice Krispies cereal
  • 24 Reese’s Peanut Butter Cups, unwrapped

Chocolate Ganache Topping

  • 2 cups chocolate chips
  • 1/2 cup heavy whipping cream

Instructions

  1. Prepare the Pan: Butter or spray a 9×13 inch pan and set it aside to ensure the treats don’t stick after setting.
  2. Melt Butter and Marshmallows: In a saucepan over low heat, melt the butter. Add the mini marshmallows and stir continuously until they are completely melted and smooth. This creates the base sticky mixture.
  3. Add Peanut Butter: Stir the creamy peanut butter into the melted marshmallow mixture thoroughly, ensuring an even flavor throughout.
  4. Combine with Cereal: Pour the Rice Krispies cereal into the marshmallow-peanut butter mixture. Stir gently but completely to coat all cereal evenly. Quickly press half of this mixture into the prepared pan, forming the first layer.
  5. Add Peanut Butter Cups: Arrange the 24 unwrapped Reese’s Peanut Butter Cups evenly over the pressed cereal layer for a delicious surprise in every bite.
  6. Top with Remaining Mixture: Spoon the remaining Rice Krispies mixture over the peanut butter cups in the pan and press it down firmly to seal the candy cups between cereal layers. Allow to cool completely so it holds its shape.
  7. Prepare Chocolate Ganache: In a saucepan over low to medium heat, combine the chocolate chips and heavy cream. Heat gently while stirring until melted and smooth, forming a creamy ganache.
  8. Finish and Set: Spread the warm ganache evenly over the top layer of the Rice Krispie treats. Let the chocolate set at room temperature before cutting into 24 squares for serving.
  9. Storage: Store the treats in a sealed container at room temperature to keep them fresh and delicious.

Notes

  • Use creamy peanut butter for the best texture and flavor integration.
  • Press the cereal mixture firmly to prevent the treats from falling apart.
  • Allow the treats to cool completely before spreading the ganache to avoid melting.
  • Store in an airtight container at room temperature for up to 3 days.
  • For a firmer finish, refrigerate after adding the ganache but bring to room temperature before serving.
