Description

Rich and fudgy Buckeye Brownies are filled with decadent chocolate and peanut butter flavor, just like the classic buckeye candy recipe! Made from dense chocolate brownies topped with fudgy peanut butter and dark chocolate ganache.

Ingredients

For the Brownie Layer

  • 1 ¼ cups (238g) granulated sugar
  • 1/3 cup (78ml) vegetable oil
  • ¼ cup (59ml) milk
  • 2 teaspoons (10ml) pure vanilla extract
  • 1 large egg
  • 1 cup (140g) all-purpose flour
  • ½ cup (40g) natural unsweetened cocoa powder
  • ¾ cups (168g) semi-sweet chocolate chips, plus additional for garnish

For the Peanut Butter Layer

  • 6 tablespoons (85g) unsalted butter, at room temperature
  • 1 cup (264g) creamy peanut butter
  • 2 cups (260g) powdered sugar, sifted
  • 1 teaspoon (5ml) pure vanilla extract

For the Chocolate Layer

  • 2 ounces (56g) dark chocolate
  • 5 tablespoons (75ml) heavy whipping cream

Instructions

For the Brownie Layer

  1. Preheat the oven to 350°F. Generously grease an 8-inch baking pan and line it with parchment paper.
  2. In a medium-sized mixing bowl, combine the granulated sugar with the oil, milk, and vanilla extract and beat together until well combined.
  3. Next, add the egg and beat just until combined, about 30 seconds or so.
  4. Combine the dry ingredients in a separate bowl and stir to combine. Add the dry ingredients to the batter and mix just until combined. Fold in the chocolate chips with a spatula.
  5. Spread the batter evenly in the prepared pan and sprinkle another handful of chocolate chips over top. Bake at 350°F for 18-22 minutes. A toothpick inserted into the center will be damp but not gooey or wet.

For the Peanut Butter Layer

  1. In a medium-sized mixing bowl combine the butter and peanut butter and beat until completely smooth and free of lumps. Add the powdered sugar and vanilla extract and beat until well combined. Spread over the cooled brownies.

For the Chocolate Layer

  1. In a microwave-safe bowl, combine the chocolate with the heavy whipping cream. Melt the chocolate in the microwave at 50% power in 30-second increments and stir until completely combined. Allow to cool. Spread over the peanut butter and allow the ganache to set. Slice and serve.

Notes

  • Storing: These are best stored in the refrigerator to keep the peanut butter and chocolate layers from softening.
  • Freezing: Finished brownies can be frozen once they’re fully set. I recommend slicing first so they will thaw faster.
  • Slicing: Use a clean knife to slice, wiping dry between cuts.
