Make the ultimate chewy Peanut Butter Rice Krispie Treats. This no-bake dessert combines creamy peanut butter, sweet marshmallows, and crispy cereal, finished with a rich chocolate swirl for a classic, nostalgic snack.

Ingredients

Scale
  • 6 tablespoons unsalted butter
  • 1 cup creamy peanut butter
  • 1 (10 ounce) package miniature marshmallows
  • 6 cups crispy rice cereal
  • 1 cup semi-sweet chocolate chips
  • 1 tablespoon butter (for topping)

Instructions

  1. Lightly grease a 9×13 inch baking pan or line it with parchment paper, leaving an overhang for easy removal.
  2. In a large saucepan, melt the 6 tablespoons of butter over low heat.
  3. Add the peanut butter to the melted butter and stir until fully combined and smooth.
  4. Add the miniature marshmallows to the saucepan. Stir constantly over low heat until the marshmallows are completely melted and smooth. Do not let the mixture brown.
  5. Remove the saucepan from the heat. Immediately add the crispy rice cereal and stir gently until the cereal is evenly coated with the marshmallow mixture.
  6. Press the mixture evenly into the prepared baking pan. Use a piece of wax paper or lightly buttered spatula to press down firmly to achieve a dense, chewy texture.
  7. In a microwave-safe bowl, combine the chocolate chips and the remaining 1 tablespoon of butter. Microwave in 30-second intervals, stirring well after each interval, until the chocolate is smooth and fully melted.
  8. Pour or drizzle the melted chocolate mixture over the top of the cereal bars. Use a knife or offset spatula to spread it evenly or create a swirl pattern.
  9. Let the treats cool completely at room temperature, about 1 hour, or chill in the refrigerator for 30 minutes until the chocolate is set.
  10. Lift the treats out of the pan using the parchment paper overhang. Cut into squares.

Notes

  • For the chewiest treats, use fresh marshmallows. Stale marshmallows result in a harder bar.
  • Press the mixture into the pan gently. Over-pressing can make the final treats too hard.
  • If you prefer a solid chocolate layer instead of a swirl, spread all the melted chocolate evenly over the bars before chilling.
  • Store leftovers in an airtight container at room temperature for up to three days.
