Ingredients

  • 1 1/4 cups all-purpose flour
  • 1 teaspoon salt
  • 2 Tablespoons Hershey's Unsweetened Cocoa
  • 11 ounces dark chocolate chopped
  • 1 cup unsalted butter cut into 1 inch cubes
  • 1 teaspoon Espresso Powder
  • 1 1/2 cups granulated sugar
  • 1/2 cup brown sugar
  • 5 eggs room temperature
  • 2 teaspoons vanilla extract
  • 9 Reese's Peanut Butter Cups chopped

Peanut Butter Drizzle

  • 1/2 cup creamy peanut butter melted

Chocolate Peanut Butter

  • 1/4 cup dark chocolate
  • 1/2 cup creamy peanut butter

Instructions

Bake brownies

  • Preheat oven to 350. Prepare a 9 x 13" baking pan with butter or cooking spray, then line parchment paper and butter or spray that as well.
  • In a medium bowl, whisk together the flour, salt and cocoa, set aside.
  • In a heat proof bowl put the chopped chocolate, the butter and the espresso powder, place bowl over a saucepan of simmering water. Stir occasionally until the butter and chocolate are melted and well combined and smooth.
  • Turn the heat off and leave the bowl over the water, add both sugars and whisk until combined. Then remove the bowl from the water and let cool to room temperature.
  • Once chocolate mixture is room temperature, 3 room temperature eggs and whisk until combined. Add the last 2 eggs, whisk until combined, then whisk in the  vanilla extract.
  • DO not over-beat the batter or the brownies will be cake like and not fudgy.
  • Sprinkle the flour mixture over the chocolate mixture, with a rubber spatula fold the flour mixture into the chocolate, until just a bit of the flour is visible. Fold in the chopped peanut butter cups.
  • Pour the mixture into the prepared pan and bake for 30 minutes, ROTATE the pan after 15 minutes, then bake for another 15 minutes.
  • Bake only until a toothpick inserted into the center comes out with a few crumbs attached. Let cool on a wire rack.

Prepare toppings

  • Melt the peanut butter topping in a microwave-safe bowl. In a separate container, melt the peanut butter and chocolate together for the chocolate peanut butter. Stir to combine.
  • Drizzle cold brownies with melted peanut butter, followed by melted chocolate peanut butter.
  • Slice bars into equal portions and enjoy!
