Ingredients

Scale

Brownie Batter

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

Peanut Butter Swirl

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

Topping

  • Chocolate chips, for sprinkling

Instructions

  1. Prepare the Brownie Batter: In a mixing bowl, combine the melted butter and granulated sugar until smooth. Add the vanilla extract and eggs, whisking continuously until fully incorporated. Sift in the cocoa powder, all-purpose flour, and baking powder. Gently fold the dry ingredients until just combined, being careful not to overmix to maintain a light batter consistency.
  2. Fill the Muffin Tin: Evenly distribute the brownie batter into muffin cups, filling each about two-thirds full to allow room for rising.
  3. Create the Peanut Butter Swirl: In a separate bowl, mix the peanut butter and powdered sugar until smooth. Place a small dollop of this peanut butter mixture in the center of each brownie cup. Using a toothpick, gently swirl it through the batter to create a marbled effect.
  4. Add the Finishing Touch: Sprinkle chocolate chips over the top of each filled muffin cup to add extra chocolate flavor and texture.
  5. Bake: Place the muffin tin in the oven and bake at 350°F (175°C) for 20 to 25 minutes, or until the edges are set and a toothpick inserted into the brownie (avoiding the peanut butter swirl) comes out with moist crumbs.
  6. Cool and Serve: Let the brownie cups cool in the pan for about 10 minutes before transferring them to a wire rack to cool completely. Serve warm or at room temperature as desired.

Notes

  • Use high-quality cocoa powder for a richer chocolate flavor.
  • To make swirling easier, warm the peanut butter mixture slightly before using.
  • Add mini marshmallows or chopped nuts to the batter for extra texture and flavor.
  • Use a muffin tin for easy removal and perfect portion sizes.
  • Be careful not to overbake to keep the brownies moist and fudgy.
  • For a professional appearance, use a piping bag to add the peanut butter swirl.
  • Serve with vanilla ice cream, caramel sauce, or a glass of milk or coffee for a delightful dessert experience.
