Ingredients

  • 1/4 cup unsalted butter
  • 1 (10 oz) bag mini marshmallows (about 5 cups)
  • 1/2 cup peanut butter
  • 6 cups Rice Krispie cereal
  • 8 oz (1 1/3 cups) chocolate chips
  • 2 tsp vegetable oil

Instructions

  1. Grease a 9×13-inch baking pan with butter or non-stick spray.
  2. In a large saucepan over low heat, melt butter, marshmallows, and peanut butter together, stirring gently until smooth.
  3. Remove from heat and stir in Rice Krispies until evenly coated.
  4. Press mixture evenly into prepared pan, using greased hands to prevent sticking.
  5. Melt chocolate chips in the microwave at medium power in 45-second bursts, stirring between each until smooth. Stir in vegetable oil.
  6. Spread melted chocolate evenly over the cereal mixture.
  7. Let bars set at room temperature for about 2 hours before cutting into squares.

Notes

  • For softer, gooier bars, reduce Rice Krispies to 5 1/2 cups.
  • Use chunky peanut butter (up to 3/4 cup) for added crunch.
  • Swirl melted white chocolate on top for a decorative look.
  • Top with mini M&Ms, sprinkles, or candies for a festive variation.
  • Do not refrigerate—bars become too hard when chilled.
