Loaded Peanut Butter Rice Krispies Squares are an irresistibly sweet and crunchy snack, packed with gooey marshmallows, creamy peanut butter, and a decadent mix of Reese’s Pieces and mini peanut butter cups. Perfect for lunchboxes, parties, or a fun dessert, these squares balance nostalgic cereal treat vibes with an over-the-top candy twist.


Ingredients

Scale

Cereal & Candy Mix

  • 10 cups Rice Krispies cereal
  • 1 cup Reese’s Pieces, divided
  • 1 cup mini peanut butter cups, sliced in half and divided

Marshmallow Mixture

  • 400 g mini marshmallows (about 8 cups)
  • ¼ cup salted butter
  • ½ cup peanut butter
  • 2 teaspoons vanilla extract

For Greasing

  • Butter or non-stick spray, for pan and hands


Instructions

  1. Prepare the Pan – Grease a 9×13-inch baking pan with butter or line it with parchment paper for easy removal and cleanup.
  2. Mix Cereal and Candy – In a large greased bowl, combine the Rice Krispies cereal with two-thirds of the Reese’s Pieces and mini peanut butter cups. Set aside the remaining candies for topping later.
  3. Melt Butter and Marshmallows – In a large saucepan over low heat, melt the butter. Add the mini marshmallows and stir constantly until they are almost fully melted and smooth.
  4. Add Peanut Butter and Vanilla – Stir in the peanut butter until thoroughly combined and creamy, then remove pan from the heat and mix in the vanilla extract.
  5. Combine Wet and Dry Ingredients – Immediately pour the warm marshmallow mixture over the cereal and candy bowl. Stir well with a greased spatula until the cereal is evenly coated and the candy is distributed throughout.
  6. Press into Pan – Transfer the mixture to your prepared pan and, using greased hands or a spatula, gently press it into an even layer without compressing too tightly.
  7. Add Toppings – Sprinkle the reserved Reese’s Pieces and peanut butter cups evenly over the top, then press down lightly so the candies stick to the surface.
  8. Cool and Serve – Allow the squares to cool at room temperature for 30–40 minutes until set, then cut into squares and serve. Enjoy!

Notes

  • For extra clean cuts, use a sharp knife and wipe it with oil before slicing.
  • Don’t over-pack the mixture into the pan or the bars may become overly dense.
  • Swap candies to suit your tastes, such as using chopped peanut butter cups or other chocolate candies.
  • Store in an airtight container at room temperature for up to 4 days.
  • Best enjoyed at room temperature—chilling will make them firmer but less gooey.
