Peanut Butter Swirl Brownie Recipe
- 6 ounces semisweet chocolate chopped
- 2 ounces unsweetened chocolate chopped
- 8 Tablespoons butter cut into 8 pieces
- ¼ cup cocoa powder
- 3 large eggs at room temperature
- 1 ¼ cup granulated sugar
- 2 teaspoons pure vanilla extract
- ½ teaspoon salt
- 1 cup all-purpose flour
- ½ teaspoon baking powder
- ⅓ cup smooth peanut butter I used Jif Peanut Butter
- Adjust oven rack to the middle position and heat oven to 350 degrees F. Lightly spray pan with nonstick cooking spray, line 9x13-inch baking pan with 2 pieces of foil, leaving a 3-inch overhang on all sides. Spray with nonstick cooking spray again, and set aside.
- In a large heat-proof bowl add chopped chocolate and butter. Microwave on 50% power for 1 minute. Stir, and microwave on 50% power for 30 seconds. Stir, and repeat until chocolate and butter are melted and smooth. Whisk in cocoa powder until smooth. Set mixture aside to cool for 5 minutes.
- Whisk eggs, sugar, vanilla, and salt into chocolate mixture until combined; then mix in flour and baking powder with a wooden spoon until combined.
- Pour batter into prepared pan, smooth into corners, and level surface. Evenly place dollops of peanut butter on top of the brownie batter. Using a butter knife create swirls by running the butter knife through the batter. Make sure you don’t touch the bottom layer of foil with the knife.
- Bake on middle rack until slightly puffed and a toothpick inserted in center comes out with just a few moist crumbs, about 25-30 minutes.
- Cool brownies to room temperature on wire rack, about 2 hours. Remove brownies from pan using foil overhang, and cut into 16-24 squares.
Makes 16-24 brownies.
