  • Total Time: 45 minutes

Ingredients

Scale

Base:

  • 3/4 cup unsalted butter, melted

  • 1 cup brown sugar

  • 1/2 cup granulated sugar

  • 2 eggs

  • 2 teaspoons vanilla extract

  • 3/4 cup creamy peanut butter

  • 1/2 teaspoon salt

  • 1 1/2 cups all-purpose flour

Frosting:

  • 1/2 cup unsalted butter, softened

  • 1 7-ounce container marshmallow fluff

  • 2 cups powdered sugar

  • 1/2 cup chopped peanuts

Instructions

  1. Preheat the oven to 175°C (350°F). Grease a 9×13-inch pan with nonstick cooking spray and set aside.

  2. In a large bowl, mix the melted butter, brown sugar, and granulated sugar using a hand mixer until blended. Add eggs and vanilla extract and mix until fully incorporated. Then mix in the peanut butter until smooth.

  3. In a separate bowl, whisk together the salt and flour. Slowly add the dry mixture to the wet mixture and mix until just combined.

  4. Spread the batter evenly into the prepared pan. Bake for 25–30 minutes, or until golden and a toothpick inserted in the center comes out clean. Let the bars cool completely after removing them from the oven.

  5. In a large bowl, beat the softened butter and marshmallow fluff together. Gradually add powdered sugar, one cup at a time, until blended and smooth.

  6. Spread the frosting evenly over the cooled bars and sprinkle chopped peanuts on top. Cut into portions and serve.
