Make the best, richest, and chewiest Peanut Butter Rice Krispie Treats using simple ingredients. This no-bake dessert is perfect for parties or a quick sweet snack.

Ingredients

Scale
  • 6 cups Rice Krispies cereal
  • 1 (10 ounce) package marshmallows
  • 1/2 cup salted butter
  • 1 cup creamy peanut butter
  • 1 teaspoon vanilla extract
  • 1 cup semi-sweet chocolate chips (for topping)
  • 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. Measure the Rice Krispies cereal into a large bowl and set aside.
  3. In a large saucepan over medium-low heat, melt the 1/2 cup of butter.
  4. Add the marshmallows to the melted butter. Stir constantly until the marshmallows are completely melted and smooth. Remove the pan from the heat.
  5. Stir in the peanut butter and vanilla extract until fully combined with the marshmallow mixture.
  6. Pour the marshmallow-peanut butter mixture over the cereal in the large bowl. Use a rubber spatula coated with cooking spray to gently fold the mixture until the cereal is evenly coated.
  7. Press the mixture evenly into the prepared baking pan. Do not press too firmly, as this can make the treats hard.
  8. Prepare the chocolate topping: In a small, microwave-safe bowl, combine the chocolate chips and 1 tablespoon of butter. Microwave in 30-second intervals, stirring between each, until smooth.
  9. Spread the melted chocolate evenly over the top of the cereal mixture. If you want a swirl, drizzle melted butterscotch chips over the chocolate before setting.
  10. Let the treats cool completely at room temperature for about 1 hour before cutting into squares.

Notes

  • For the chewiest bars, use fresh marshmallows. Stale marshmallows result in harder treats.
  • If you prefer a richer flavor, use natural creamy peanut butter.
  • To prevent sticking while pressing the mixture into the pan, lightly grease your hands or the spatula with butter or cooking spray.
