Peanut Butter Blondies with Fudge Frosting

Ingredients

For the Blondies:

  • 1/2 cup (1 stick) unsalted butter, melted
  • 1 cup brown sugar, packed
  • 1/2 cup creamy peanut butter
  • 1 large egg
  • 1 tsp vanilla extract
  • 1/4 tsp salt
  • 1 cup all-purpose flour

For the Fudge Frosting:

  • 1/4 cup unsalted butter
  • 1/4 cup milk
  • 1/4 cup unsweetened cocoa powder
  • 2 cups powdered sugar
  • 1/2 tsp vanilla extract

Instructions

To Make the Blondies:

  1. Preheat oven to 350°F (175°C). Line an 8×8-inch pan with parchment paper or grease it lightly.
  2. In a large bowl, mix melted butter and brown sugar until smooth.
  3. Stir in the peanut butter, then add the egg and vanilla. Mix until fully combined.
  4. Add the salt and flour, and stir just until no streaks remain—don’t overmix.
  5. Spread the batter evenly in the prepared pan.
  6. Bake for 20–25 minutes or until the top is golden and a toothpick inserted in the center comes out with moist crumbs.
  7. Let the blondies cool completely in the pan.

To Make the Fudge Frosting:

  1. In a saucepan over medium heat, melt the butter with the milk.
  2. Whisk in the cocoa powder until smooth, then remove from heat.
  3. Stir in the powdered sugar and vanilla until a thick, spreadable frosting forms.
  4. Spread the frosting over cooled blondies and allow to set before slicing into squares.
