Celebrate the perfect combination of chocolate and nuts and make a batch of these simple swirled peanut butter brownies. They are decadent!
For brownie batter
1–1/2 sticks unsalted butter, cubed, plus more for pan
2 ounces unsweetened chocolate, finely chopped
1/4 cup + 2 tablespoons unsweetened cocoa powder
2 cups granulated sugar
3 large eggs
2 teaspoons vanilla extract
1 cup all-purpose flour
For peanut butter swirl
4 tablespoons unsalted butter, melted
1/2 cup confectioners’ sugar
3/4 cup smooth peanut butter
1/4 teaspoon salt
1/2 teaspoon vanilla extract
Preheat the oven to 350 degrees F. Lightly butter a foil-lined 9-inch square baking pan.
For the brownie batter, melt the butter and chocolate in a large saucepan over low heat, stirring occasionally. Remove from heat and add the cocoa powder, sugar, eggs and vanilla extract thoroughly mixing after each addition. Gently fold in the flour.
For the peanut butter swirl, stir together the butter, confectioners’ sugar, peanut butter, salt and vanilla extract in a small bowl.
Spread one-third of the chocolate batter in the bottom of the prepared baking pan. Spoon tablespoon-sized dollops of the peanut mixture about 1 inch apart in the pan. Spoon the remaining brownie batter around the peanut butter. Gently drag a butter knife through the batter both lengthwise and crosswise to make swirls. Tap the bottom of the pan on a counter to smooth out the batter into an even layer.
Bake for 35-40 minutes until a toothpick inserted in the center comes out with a bit of batter. Cool and cut into 16 squares.
