These Butterfinger Rice Krispies Treats combine the classic chewy texture of Rice Krispies with the rich flavors of peanut butter and crunchy Butterfinger candy pieces for an irresistible, fun snack or dessert.

Ingredients

Base Ingredients

  • ¼ cup unsalted butter
  • 10.5 ounces mini marshmallows
  • ½ cup creamy peanut butter
  • 6 cups Rice Krispies cereal

Additional Mix-ins

  • 5.7 ounces Butterfinger candy bars (3 regular size or 9 Fun Size bars)

Instructions

  1. Prepare Pan: Spray a 9 x 13-inch baking dish with cooking spray to prevent sticking and set aside.
  2. Crush Butterfingers: Place Butterfinger candy bars into a plastic bag and crush them using a rolling pin or mallet. It’s okay to have some larger chunks for texture.
  3. Melt Butter and Marshmallows: In a large non-stick pot over medium heat, melt the unsalted butter. Add the mini marshmallows and stir continuously until fully melted and smooth.
  4. Add Peanut Butter: Remove the pot from heat and quickly stir in the creamy peanut butter until it is completely melted and evenly mixed in.
  5. Combine Butterfingers: Stir the crushed Butterfinger pieces into the marshmallow mixture, ensuring they are well incorporated.
  6. Add Rice Krispies: Add the Rice Krispies cereal to the pot and mix thoroughly, coating all the cereal evenly with the marshmallow and peanut butter mixture.
  7. Press Mixture in Pan: Pour the combined mixture into the prepared baking dish. Use a greased rubber spatula to evenly spread and press the mixture down firmly.
  8. Cool and Set: Allow the bars to cool completely at room temperature for about 1 hour to set before cutting into squares and serving.

Notes

  • You can substitute creamy peanut butter with natural peanut butter if preferred, but it will alter the texture slightly.
  • Do not refrigerate the bars to set; cooling at room temperature maintains the best chewiness.
  • For easier cutting, grease the knife or use a plastic knife to prevent sticking.
  • These treats are best enjoyed within 2-3 days stored in an airtight container at room temperature.
