Ingredients
 
 

  • ¾ cup all purpose flour
  • 2 tablespoons cocoa powder
  • ½ teaspoon fine sea salt
  • ½ cup unsalted butter
  • ¾ teaspoon espresso powder
  • cup chocolate chips, bittersweet or semi-sweet
  • ¾ cup granulated sugar
  • ¼ cup light brown sugar, packed
  • 3 large eggs, room temperature
  • 1 teaspoon pure vanilla extract
  • ¼ cup peanut butter
  • cup peanut butter cups, chopped

Instructions
 

  • In medium bowl, whisk together the flour, cocoa powder and salt. Whisk to break up any lumps in the cocoa powder.
    ¾ cup all purpose flour, 2 tablespoons cocoa powder, ½ teaspoon fine sea salt
  • In a medium saucepan over low heat, melt the butter and espresso powder. Remove from the heat.
    ½ cup unsalted butter, ¾ teaspoon espresso powder
  • Stir in the chocolate chips until fully melted and smooth. If there is chocolate that hasn’t melted, put back on low heat and stir until melted.
    ⅔ cup chocolate chips, bittersweet or semi-sweet
  • Whisk in the granulated sugar and brown sugar.
    ¾ cup granulated sugar, ¼ cup light brown sugar, packed
  • Whisk in the eggs, one at a time, stirring after each addition. Whisk in the vanilla.
    3 large eggs, room temperature, 1 teaspoon pure vanilla extract
  • Fold in the flour mixture, stirring until just combined. Scrape down the sides and bottom of the bowl with a spatula to ensure everything is fully mixed.
  • Fold in half of the chopped peanut butter cups.
    ⅔ cup peanut butter cups, chopped
  • Spread the brownie batter into the prepared pan in an even layer.
  • Warm the peanut butter in the microwave for 20-30seconds until it has softened and thinned. It should be slightly liquidy and have the consistency of caramel sauce.
  • Dollop spoonfuls of the peanut butter over the brownie batter. Create swirls in the batter with a toothpick.
    ¼ cup peanut butter
  • Sprinkle the remaining half of the chopped peanut butter cups on top of the brownies.
  • Bake for 25-35 minutes, or until a toothpick inserted in the center comes out with a few moist crumbs.
  • Let the brownies cool to room temperature, or just warm, then cut into squares and serve.
