Ingredients

Units Scale

Main Ingredients

  • 1/2 cup (1 stick) butter
  • 1 cup creamy peanut butter
  • 1 1/2 cups marshmallow fluff
  • 1 teaspoon vanilla extract
  • 3 1/2 cups powdered sugar
  • 1 cup graham cracker crumbs or rice crisps

Instructions

  1. Prepare Your Pan: Line an 8×8-inch baking dish with parchment paper or lightly grease it to ensure your bars come out clean and intact after setting.
  2. Melt the Butter and Peanut Butter: In a medium saucepan over low heat, gently melt the butter and peanut butter together until smooth and combined, stirring frequently to prevent burning.
  3. Add Marshmallow Fluff and Vanilla: Remove the pan from heat and stir in the marshmallow fluff and vanilla extract until the mixture is smooth and glossy. This will be the gooey base of your bars.
  4. Incorporate the Dry Ingredients: Gradually add the powdered sugar and graham cracker crumbs (or rice crisps) into the wet mixture, stirring constantly until combined into a thick, sticky batter with some crunch.
  5. Press Into Pan and Chill: Transfer the mixture into your prepared pan, pressing evenly with a spatula or your hands to create an even layer. Refrigerate for at least two hours or until firm.
  6. Slice and Serve: Once set, remove the bars using the parchment paper, slice into desired bar sizes, and enjoy your Fluffernutter Bars.

Notes

  • Use peanut butter and butter at room temperature for easier melting and mixing.
  • Press the mixture firmly into the pan to prevent crumbly bars that fall apart.
  • Choose natural or creamy peanut butter for the best flavor and texture.
  • Allow enough chilling time so the bars hold their shape when cut.
  • Use a sharp knife warmed under hot water and wiped clean before slicing for smoother cuts.
