Peanut Butter Swirl Brownies
- 8 tablespoons (1 stick) unsalted butter, cut into small pieces, plus more for the pan
- 2 ounces good-quality unsweetened chocolate, coarsely chopped
- 4 ounces good-quality semisweet chocolate, coarsely chopped
- 2/3 cup all-purpose flour
- 1/2 teaspoon baking powder
- 1/4 teaspoon salt
- 3/4 cup granulated sugar
- 3 large eggs
- 2 teaspoons pure vanilla extract
- 4 tablespoons unsalted butter, melted
- 1/2 cup confectioners sugar
- 3/4 cup smooth peanut butter
- 1/4 teaspoon salt
- 1/2 teaspoon pure vanilla extract
- Preheat the oven to 325F.
- Line a buttered 8-inch-square baking pan with foil or parchment paper, allowing 2 inches to hang over the sides.
- Butter the lining (excluding the overhang); set the pan aside.
- Make the batter: Put the butter and chocolates in a heatproof medium bowl set over a pan of simmering water; stir until melted.
- Let cool slightly.
- Whisk together the flour, baking powder, and salt in a separate bowl, and set aside.
- Whisk the granulated sugar into the chocolate mixture.
- Add the eggs, and whisk until the mixture is smooth.
- Stir in the vanilla.
- Add the flour mixture; stir until well incorporated.
- Make the filling: Stir together the butter, confectioners sugar, peanut butter, salt, and vanilla in a bowl until smooth.
- Pour one-third of the batter into the prepared pan, and spread evenly with a rubber spatula.
- Place dollops of filling (about 1 tablespoon each) about 1 inch apart on top of the batter.
- Drizzle the remaining batter on top, and gently spread to fill the pan.
- Place dollops of the remaining filling on top.
- With a butter knife, gently swirl the filling into the batter, running the knife lengthwise and crosswise through the layers.
- Bake until a cake tester inserted into the brownies (avoid center and edges) comes out with a few crumbs but is not wet, about 45 minutes.
- Let cool slightly in the pan, about 15 minutes.
- Lift out the brownies; let cool completely on a wire rack before cutting into squares.
