Ingredients

  • 12 Tbsp butter cut into Tablespoon-sized pieces, 170g
  • 3/4 cup cocoa powder 75g
  • 1 2/3 cup granulated sugar 345g
  • 1 Tablespoon water 15ml
  • 1 teaspoon vanilla extract 5ml
  • 2 large eggs + 1 large egg yolk lightly beaten
  • 1 ⅓ cup all-purpose flour 170g
  • ½ teaspoon baking powder 2g
  • ¼ teaspoon salt 2g

Peanut Butter Fudge

  • 2 cups creamy peanut butter 475g
  • 1/2 cup butter chopped into about 8 pieces, 113g
  • 1 teaspoon vanilla extract 5ml
  • 2 1/4 cups powdered sugar 360g
  • 1 Tablespoon milk 15ml

Chocolate Ganache

  • 1 1/2 cups chocolate chips 265g
  • 6 Tablespoons butter cut into pieces, 85g

Instructions

  • Preheat oven to 350F (177C) and lightly grease/spray a 13x9 pan (or line with parchment paper).
  • In a large, microwave-safe bowl, heat butter in microwave until melted.
  • Stir in cocoa powder and sugar.
  • Add water and vanilla extract and stir until combined.
  • Add eggs and egg yolk, stir well.
  • In a separate, medium-sized bowl, combine flour, baking powder and salt.
  • Gradually add to butter mixture until completely combined.
  • Spread batter evenly into prepared pan and bake on 350F (177C) for 25 minutes. Allow to cool completely before covering with peanut butter fudge.

Peanut Butter Fudge

  • Combine peanut butter and butter in large heat proof bowl and microwave at 15-second increments (stirring between each) until butter is completely melted.
  • Stir in vanilla extract.
  • Gradually add/stir in powdered sugar.
  • Add milk and stir well. Mixture should be fudgy enough that you can mold pieces into a ball, but not too stiff that you won't be able to spread it over the brownies (feel free to add additional milk, 1 teaspoon at a time, if mixture is too stiff, or more powdered sugar, 1 Tablespoon at a time if mixture is too soft).
  • Drop peanut butter mixture by heaping spoonfuls over the cooled brownies and use a knife to gently spread until the brownies are evenly covered with a thick layer of fudge.
  • Prepare chocolate fudge frosting by combining chocolate chips and remaining butter in a medium heat-proof bowl and microwaving at 15-second increments (stirring well between) until completely melted.
  • Evenly pour chocolate over fudge, spread with a knife.
  • Allow chocolate to set before slicing and serving (30-60 minutes).
