Ingredients

Main Ingredients

  • ½ cup unsalted butter
  • 2 packages mini-marshmallows (10 ounces each), divided use
  • 1 cup creamy peanut butter (such as Jif or Skippy)
  • Pinch of sea salt
  • 1 teaspoon pure vanilla extract
  • 5 cups Cocoa Krispies cereal
  • 5 cups Cap’n Crunch’s Peanut Butter Crunch cereal

Topping

  • 1 cup semi-sweet or dark chocolate chips
  • 1 cup Reese’s peanut butter baking chips
  • 1 bag Reese’s Minis Unwrapped (7.6 ounces)

Instructions

  1. Prepare the Pan: Grease a Nordic Ware Metal 9×13 Covered Cake Pan lightly with butter or non-stick spray to prevent sticking. Set aside.
  2. Melt Butter and Marshmallows: In a 6-quart Dutch Oven over low heat, melt ½ cup unsalted butter. Add 1 ½ packages (approximately 15 ounces) of mini-marshmallows and stir continuously until fully melted and smooth.
  3. Add Peanut Butter, Salt, and Vanilla: Stir in 1 cup creamy peanut butter, a pinch of sea salt, and 1 teaspoon pure vanilla extract until the mixture is fully combined and smooth.
  4. Mix in Cereals: Remove the melted marshmallow mixture from heat. Immediately fold in 5 cups Cocoa Krispies cereal and 5 cups Cap’n Crunch’s Peanut Butter Crunch cereal gently until all cereals are evenly coated.
  5. Press into Pan: Using a buttered spatula or wax paper, evenly press the cereal mixture into the prepared 9×13 pan, creating a compact and even layer.
  6. Melt Topping Chips: In a microwave-safe bowl, melt 1 cup semi-sweet or dark chocolate chips along with 1 cup Reese’s peanut butter baking chips in 30-second increments, stirring between each until smooth and fully melted.
  7. Top Treats with Chocolate Mixture: Pour the melted chocolate and peanut butter chip mixture evenly over the pressed cereal base in the pan. Spread gently to cover the entire surface.
  8. Add Reese’s Minis: Immediately sprinkle the entire bag (7.6 ounces) of Reese’s Minis Unwrapped evenly over the melted chocolate topping to create a decorative and flavorful finish.
  9. Cool and Set: Allow the treats to cool at room temperature for at least 1 hour until the chocolate topping is completely set and firm.
  10. Cut and Serve: Once set, cut the layered treats into approximately 15 squares and serve. Store any leftovers in an airtight container at room temperature or refrigerated to maintain freshness.

Notes

  • Use a buttered spatula or wax paper to press the cereal mixture into the pan to avoid sticking.
  • For easier cutting, chill the treats briefly after the chocolate topping sets.
  • You can substitute the cereals with similar peanut butter and chocolate flavored varieties if unavailable.
  • Store treats in an airtight container for up to 3 days at room temperature or up to one week refrigerated.
  • Adjust the amount of Reese’s Minis on top based on your preference for added crunch and flavor.
