Ingredients

Scale

Brownie Batter

  • 1/2 cup (115g) melted butter
  • 1 cup (200g) granulated sugar
  • 2 tsp vanilla extract
  • 2 large eggs
  • 1/3 cup (40g) cocoa powder
  • 1/2 cup (65g) all-purpose flour
  • 1/4 tsp baking powder

Peanut Butter Swirl

  • 1/2 cup (125g) peanut butter
  • 1/3 cup (40g) powdered sugar

Topping

  • 1/4 cup (45g) chocolate chips

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 well until fully incorporated. Sift in the cocoa powder, all-purpose flour, and baking powder. Gently mix just until combined, being careful not to overmix to maintain a light batter consistency.
  2. Fill the Muffin Tin: Evenly spread the brownie batter into the prepared 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 with powdered sugar until smooth. Drop a small amount of this peanut butter mixture into the center of each brownie cup. Use a toothpick to gently swirl the peanut butter through the chocolate batter for a marbled effect.
  4. Add the Finishing Touch: Sprinkle chocolate chips over each brownie cup to add extra chocolatey sweetness and texture.
  5. Bake: Bake the brownie cups in a preheated oven at 350°F (175°C) for 20 to 25 minutes, or until the edges are set and a toothpick inserted into the chocolate (avoiding the peanut butter swirl) comes out with moist crumbs.
  6. Cool and Serve: Allow the brownie cups to cool in the pan for about 10 minutes before transferring them to a wire rack to cool completely. Serve as is or with your favorite accompaniments.

Notes

  • Choose a high-quality cocoa powder for an intense chocolate flavor.
  • Lightly heat the peanut butter mixture before swirling to make the process easier.
  • For added texture and fun, try adding mini marshmallows or chopped nuts to the batter.
  • Use a muffin tin to easily remove and serve the brownie cups.
  • Avoid overbaking to keep the brownies moist and fudgy.
  • Use a piping bag for precise peanut butter swirls if you want a professional look.
