Ingredients
  

Main Ingredients

  • 3 cups Rice Krispies cereal
  • 1 cup smooth peanut butter Use natural peanut butter but stir well first.
  • 1 cup marshmallows About one standard 7–8 oz bag’s worth (mini or regular).
  • 1/4 cup unsalted butter Can substitute with coconut oil for a dairy-free version.
  • 1/2 cup chocolate chips Semi-sweet or milk, depending on sweetness preference.

Instructions
 

Preparation

  • Grease a 9×13 inch pan with a little butter or line it with parchment for easy removal.
  • In a large saucepan over low heat, melt the butter and marshmallows together. Stir constantly and scrape the bottom so the marshmallows soften evenly until smooth and glossy.
  • Remove the pan from the heat, add the peanut butter, and stir until fully incorporated and smooth.
  • Add the Rice Krispies cereal to the mixture, folding quickly and gently until the cereal is evenly coated.

Assembly

  • Transfer the mixture to the prepared pan and press evenly into the pan using a spatula or a piece of parchment/waxed paper.
  • In a microwave-safe bowl, heat the chocolate chips in 20–30 second bursts, stirring in between, until melted and smooth. Drizzle the melted chocolate over the pressed mixture.
  • Let cool at room temperature until set, about 30–60 minutes. Cut into squares and serve.

Notes

Store in an airtight container at room temperature for up to 3 days. For a vegan version, use vegan marshmallows and dairy-free butter. Can freeze individually wrapped bars for up to 3 months.
