These Buckeye brownies combine a fudgy chocolate base with a creamy peanut butter swirl for a rich, comforting treat that’s quick and easy to make.

Ingredients

Scale
  • 1/2 cup (115g) unsalted butter, melted
  • 1 cup (200g) granulated sugar
  • 2 large eggs, room temperature
  • 1 teaspoon pure vanilla extract
  • 3/4 cup (95g) all-purpose flour (can substitute almond flour for gluten-free)
  • 1/2 cup (50g) unsweetened cocoa powder
  • 1/4 teaspoon salt
  • 1/4 teaspoon baking powder
  • 1/2 cup (125g) creamy peanut butter, preferably natural with a bit of salt
  • 1/3 cup (40g) powdered sugar
  • 12 tablespoons (15-30ml) milk

Instructions

  1. Preheat your oven to 350°F (175°C). Grease an 8×8-inch pan or line it with parchment paper, leaving a slight overhang.
  2. In a large bowl, whisk together the melted unsalted butter and granulated sugar until combined but not grainy, about 1-2 minutes.
  3. Add the eggs one at a time, whisking well after each addition. Stir in the vanilla extract.
  4. Sift together the all-purpose flour, unsweetened cocoa powder, salt, and baking powder in a separate bowl.
  5. Gradually fold the dry ingredients into the wet mixture using a spatula. Mix just until no dry flour streaks remain.
  6. Transfer the batter into your prepared baking pan, smoothing it out evenly.
  7. In a small bowl, combine the creamy peanut butter and powdered sugar. Add milk one tablespoon at a time until thick but spreadable.
  8. Drop spoonfuls of the peanut butter mixture randomly over the chocolate batter. Use a toothpick or skewer to gently swirl it, creating ribbons.
  9. Bake for 25-30 minutes. Check at 25 minutes with a toothpick; it should come out with a few moist crumbs but no wet batter.
  10. Remove from oven and let cool completely in the pan on a wire rack.
  11. Use the parchment overhang to lift the brownies out, then cut into squares and enjoy.

Notes

Use natural peanut butter with a bit of salt for best flavor. Avoid overmixing the batter to keep brownies fudgy. Let brownies cool completely before cutting for best texture. If peanut butter swirl sinks, swirl immediately after pouring batter. Tent with foil if oven runs hot to prevent over-browning.
