Ingredients

Scale

Main Ingredients

  • 6 cups Rice Krispies cereal
  • 6 tablespoons unsalted butter
  • 6 cups mini marshmallows (divided)
  • 1 cup creamy peanut butter
  • Pinch salt (if your peanut butter doesn’t have any)
  • 7.5 ounce container of Marshmallow Fluff

Instructions

  1. Prepare the Pan: Line a 9×13 inch baking pan with parchment paper, allowing the edges to hang over the sides for easy removal later. Spray the parchment with nonstick spray and set the pan aside.
  2. Set Up Cereal: Pour the Rice Krispies cereal into a large mixing bowl and set it aside for combining later.
  3. Melt Butter and Marshmallows: In a medium saucepan over low heat, melt the unsalted butter. Add 4 cups of the mini marshmallows and stir frequently until they melt and the mixture is mostly combined. It’s fine if the marshmallows aren’t fully incorporated, as this will help achieve the right texture.
  4. Add Peanut Butter and Salt: Remove the saucepan from the heat and stir in the creamy peanut butter. If your peanut butter is unsalted, add a pinch of salt now to enhance the flavors and stir to combine thoroughly.
  5. Mix with Cereal and Additional Ingredients: Immediately pour the peanut butter mixture over the Rice Krispies in the large bowl. Add the Marshmallow Fluff and the remaining 2 cups of mini marshmallows. Stir everything together until the cereal is evenly coated.
  6. Press into Pan: Transfer the mixture into the prepared baking pan and press down firmly to create an even layer. For an even surface, you can use the bottom of another 9×13 inch pan, spray your hands with nonstick spray and press with your palms, or place a piece of parchment paper on top and press down.
  7. Let Set and Serve: Allow the treats to set at room temperature for at least 15 minutes to firm up. Once set, lift the treats out using the parchment edges, slice into 12 large bars, and serve.

Notes

  • Using unsalted butter and adding a pinch of salt can balance sweetness, especially if peanut butter is unsalted.
  • Pressing the mixture evenly helps the bars set better and slice cleanly.
  • Store treats in an airtight container at room temperature for up to 3 days for optimal freshness.
