Ingredients

Scale

Brownie Batter

  • 1/2 cup unsalted butter, melted
  • 1 cup granulated sugar
  • 2 large eggs
  • 1 teaspoon vanilla extract
  • 1/3 cup unsweetened cocoa powder
  • 1/2 cup all-purpose flour
  • 1/4 teaspoon salt
  • 1/4 teaspoon baking powder

Peanut Butter Swirl and Topping

  • 1/2 cup creamy peanut butter
  • 1/4 cup powdered sugar
  • 1/2 cup chocolate chips

Optional Substitutions

  • Use almond butter instead of peanut butter for a nutty twist.
  • Substitute gluten-free flour for all-purpose flour to make this recipe gluten-free.

Instructions

  1. Preheat the Oven: Preheat your oven to 350°F (175°C) and line a muffin tin with paper liners to prepare for baking.
  2. Prepare the Brownie Batter: In a mixing bowl, whisk together the melted butter and granulated sugar until smooth and well combined. Add the eggs and vanilla extract, continuing to whisk until fully incorporated. Sift in the cocoa powder, all-purpose flour, salt, and baking powder. Stir gently until just combined, taking care not to overmix to maintain a light, fudgy texture.
  3. Fill the Muffin Tin: Spoon the brownie batter evenly into the prepared muffin cups, filling each about two-thirds full to allow room for rising and swirling.
  4. Create the Peanut Butter Swirl: In a small bowl, mix the creamy peanut butter with powdered sugar until smooth. Drop a small spoonful of this peanut butter mixture into the center of each brownie cup, then use a toothpick to gently swirl it through the batter for a marbled effect.
  5. Add the Finishing Touch: Sprinkle chocolate chips evenly over the top of each brownie cup to add extra chocolate flavor and texture.
  6. Bake: Place the muffin tin in the oven and bake for 20 to 25 minutes. The edges should be set, and a toothpick inserted into the brownie (avoiding the peanut butter swirl) should come out with a few moist crumbs, indicating just-right doneness.
  7. Cool and Serve: Let the brownie cups cool in the tin for about 10 minutes to firm up before transferring them to a wire rack to cool completely. Serve as is or with your favorite accompaniments like vanilla ice cream or a drizzle of caramel sauce.

Notes

  • Use high-quality unsweetened cocoa powder for a richer chocolate flavor.
  • Gently warm the peanut butter mixture before swirling to make it easier to incorporate.
  • Add chopped nuts or mini marshmallows to the batter for additional texture and flavor variations.
  • Avoid overbaking to keep the brownies moist and fudgy.
  • Use a piping bag for perfect peanut butter swirls if you want a more professional presentation.
