Ingredients

Scale

Main Ingredients:

  • 1 1/2 cups all-purpose flour
  • 3/4 cup creamy peanut butter
  • 2 eggs
  • 1 7-ounce container marshmallow fluff

Sugars:

  • 1 cup brown sugar
  • 1/2 cup granulated sugar
  • 2 cups powdered sugar

Fats and Enhancers:

  • 3/4 cup unsalted butter, melted
  • 1/2 cup unsalted butter, softened
  • 2 teaspoons vanilla extract
  • 1/2 teaspoon salt
  • 1/2 cup chopped peanuts

Instructions

  1. Preheat oven to 175°C (350°F) and prepare a 9×13-inch pan with nonstick cooking spray, ensuring complete coverage.
  2. In a large mixing bowl, cream melted butter with brown and granulated sugars using a hand mixer until well combined and slightly fluffy.
  3. Incorporate eggs and vanilla extract into the sugar mixture, blending thoroughly until smooth and uniform in texture.
  4. Mix in peanut butter until the batter becomes creamy and consistent, eliminating any visible lumps.
  5. In a separate bowl, sift flour and salt together to remove potential clumps and ensure even distribution.
  6. Gradually fold dry ingredients into the wet mixture, stirring gently until just combined to maintain the batter’s delicate texture.
  7. Transfer batter to the prepared pan, spreading evenly with a spatula to create a smooth, level surface.
  8. Bake for 25-30 minutes, or until edges turn golden brown and a toothpick inserted in the center emerges clean.
  9. Remove from oven and allow bars to cool completely at room temperature, which helps set the texture.
  10. For frosting, whip softened butter and marshmallow fluff together until light and airy.
  11. Gradually add powdered sugar, mixing until the frosting becomes smooth and spreadable.
  12. Once bars are completely cooled, generously spread frosting across the entire surface.
  13. Garnish with chopped peanuts for added crunch and visual appeal.
  14. Slice into squares and serve at room temperature.

Notes

  • Swap Peanut Butter for Dietary Needs: Use almond or sunflower seed butter for gluten-free or nut-free variations, ensuring everyone can enjoy these delectable bars.
  • Control Sweetness Levels: Reduce powdered sugar in frosting by half for a less sweet version, allowing the rich peanut butter flavor to shine through.
  • Enhance Texture Tip: Slightly underbake bars for extra gooey centers, creating a more decadent dessert experience that melts in your mouth.
  • Storage Hack: Refrigerate bars for firmer frosting and easier cutting, keeping them fresh for up to 5 days in an airtight container.
