Ingredients

  • ½ cup chunky peanut butter
  • ¼ cup butter softened
  • 1 teaspoon vanilla extract
  • 1 cup brown sugar firmly packed
  • 2 large eggs
  • ½ cup all purpose flour
  • 1 cup chopped peanuts
  • ¼ cup powdered sugar

Instructions

  • Preheat the oven to 350°F. Line an 8x8-inch baking pan with parchment paper and set aside.
  • In a large mixing bowl, cream together the peanut butter, butter, and vanilla extract until smooth. Gradually add the brown sugar and beat until well combined.
    Brown sugar is being added to a mixing bowl with creamed peanut butter and butter.
  • Add the eggs, one at a time, beating well after each addition.
    An egg is being added to the creamed peanut butter mixture in a large mixing bowl while preparing blondie batter.
  • Add the flour in two batches, mixing just until combined. Fold in the chopped peanuts.
    Chopped peanuts are folded into thick peanut butter blondie batter with a silicone spatula.
  • Spread the batter evenly into the prepared baking pan.
    Blondie batter is spread evenly into a parchment-lined square baking pan, ready to bake.
  • Bake for 30 minutes, or until the center is set and a toothpick inserted near the center comes out with a few moist crumbs.
  • Cool in the pan for 15 to 20 minutes. Using the parchment paper, lift the blondies from the pan and place on a wire rack to cool completely.
  • Cut into 2-inch bars and dust with powdered sugar before serving.
