Make the best no bake peanut butter Rice Krispie treats that are soft, gooey, and hold together perfectly. This easy recipe delivers nostalgic flavor fast.

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 (for optional topping)
  • 1 teaspoon coconut oil (for optional 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 over medium-low heat, melt the butter.
  3. Once the butter is melted, stir in the peanut butter until completely smooth.
  4. Add the miniature marshmallows to the saucepan. Stir constantly until the marshmallows are fully melted and the mixture is smooth. Keep the heat low to prevent scorching.
  5. Remove the saucepan from the heat immediately.
  6. Pour the crispy rice cereal into the marshmallow and peanut butter mixture. Fold gently with a rubber spatula until the cereal is evenly coated. Do not overmix, as this can make the treats hard.
  7. Press the mixture evenly into the prepared baking pan. Use a piece of wax paper or lightly buttered hands to press down gently; avoid packing too tightly to keep them chewy.
  8. If adding the chocolate topping, combine the chocolate chips and coconut oil in a microwave-safe bowl. Microwave in 30-second intervals, stirring between each, until smooth.
  9. Spread the melted chocolate evenly over the top of the cereal mixture.
  10. Let the treats cool completely at room temperature, about 1 hour, before cutting into squares.
  11. Lift the treats out of the pan using the parchment paper overhang and cut into bars.

Notes

  • For the chewiest texture, use fresh marshmallows. Stale marshmallows result in harder treats.
  • If you want to make Scotcharoos, substitute half of the chocolate chips with butterscotch chips in the topping layer.
  • To prevent sticking when pressing the mixture into the pan, lightly spray your hands or a spatula with non-stick cooking spray.
  • This recipe makes sturdy Rice Krispie Bars that resist crumbling when cut.
