Ingredients

  • ⅔ cup melted butter
  • 1⅓ cups granulated sugar
  • 1 cup light brown sugar
  • 4 large eggs
  • 2 teaspoons vanilla extract
  • 1 cup creamy or chunky peanut butter
  • 2 cups all-purpose flour
  • 2 teaspoons baking powder
  • ¼ teaspoon salt
  • ½ cup Reese’s Pieces

Instructions

  • Preheat the oven to 350°F (175°C) and line the pan with parchment paper, leaving an overhang for easy lifting.
  • In a large bowl, mix melted butter, both sugars, and peanut butter until smooth. Beat in the eggs one at a time, then stir in vanilla and salt.
  • Whisk flour and baking powder in a separate bowl, then fold into the wet mixture until just combined.
  • Spread the batter evenly in the pan, top with Reese’s Pieces, and bake for 30–35 minutes until set but still slightly soft in the center.
  • Cool for 30 minutes before lifting out and slicing into squares.
