Instructions
 

Brownies

  • Prepare Pan: Preheat the oven to 350℉. Line a 9x13-inch baking pan with parchment paper, leaving an overhang on the sides to create a parchment sling.
  • Combine Butter, Coffee, and Cocoa Powder: Melt butter. In a large bowl, stir cocoa powder and coffee into the melted butter until smooth.
  • Add Sugar, Eggs, and Vanilla: Stir in sugar until well combined. Then add the vanilla and eggs mixing well.
  • Add Flour and Salt: Throughly mix the flour into the batter until well combined. Pour batter into the prepared pan.
  • Bake: Bake for 30 minutes or until a toothpick inserted into the center comes out with a few moist crumbs. Cool completely

Peanut Butter Filling:

  • Combine Ingredients: Using a hand mixer or a food processor, combine softened cream cheese, peanut butter, and sugar until smooth.
  • Spread Filling: Evenly spread the peanut butter filling over the cooled brownies. Set aside.
  • Chocolate Ganache
  • Make Ganache: Heat heavy cream in a saucepan until hot but not boiling. Remove from heat and add chopped chocolate and corn syrup (if using). Stir until smooth and glossy.
  • Spread Ganache. Using a offset spatula, evenly spread the ganache over the peanut butter layer.

Chill and Serve

  • Chill: Place the assembled brownies in the fridge for at least two hours or until firm
  • Cut and Serve: Lift the brownies out of the pan using the parchment sling. Use a sharp knife to cut into squares, wiping the knife clean between cuts to show off the layers.

Notes

  • For extra texture, sprinkle chopped peanuts over the ganache before chilling.
  • Dark chocolate can be substituted for semi-sweet in the ganache for a richer flavor.
  • Use a processed Peanut Butter like Jiffy or Skippy.
  • Store brownies in an airtight container in the fridge for up to a week.
  • These brownies can be made a day ahead and improve as they chill.
  • The brownies are adapted from Smitten's Kitchens's Cocoa Brownies
