Peanut Butter Overload Bars

Serves: 15


  • 1 cup (226 g) unsalted butter, melted
  • 1 cup (250 g) smooth peanut butter
  • 1 3/4 cups (385 g) light brown sugar, packed
  • 2 eggs, slightly cold
  • 2 teaspoons (5.2 g) vanilla extract
  • 2 cups(240 g)  all-purpose flour
  • 2 teaspoons (8 g) baking soda
  • 1 teaspoon (6 g) salt
  • 1 cup (180 g) Reese’s peanut butter baking chips
  • 1 (9.9 ounce) bag Reese’s Pieces candy
  • 1 cup (250 g) smooth peanut butter


  1. Preheat the oven to 350 degrees F. Spray a 9×13-inch baking pan with nonstick spray, line with parchment paper, and spray again. Set aside.
  2. In the bowl of a stand mixer fitted with the paddle attachment, stir together the melted butter and peanut butter until smooth.
  3. With the mixer on medium speed, add the brown sugar, followed by the eggs and vanilla.
  4. With the mixer on low speed, stir in the flour, baking soda, and salt until no streaks of flour remain.
  5. Fold in the peanut butter chips.
  6. Spread the dough evenly in the prepared pan and bake for 15 to 20 minutes.
  7. Remove from oven and cool on a cooling rack for about 10 to 15 minutes.
  8. Using a spoon or an offset icing spatula, spread the remaining peanut butter over the bars while the bars are still warm. Sprinkle with Reese’s Pieces and allow the bars to cool completely before serving.

Courtney’s Note: Want a little less peanut butter? Swap M&Ms for the Reese’s Pieces on top of the bars.
