Cheesecake Swirl Brownies

Ingredients

• 6 tablespoons unsalted butter
• 6 ounces bittersweet chocolate, finely chopped
• 1/4 teaspoon salt
• 3/4 cup plus 4 tablespoons granulated sugar, divided
• 3 large eggs, divided
• 2 teaspoons vanilla extract, divided
• 1/4 cup sour cream
• 3/4 cup all purpose flour
• 1/4 cup cocoa
• 1/2 teaspoon baking powder
• 8 ounces cream cheese, softened

Directions

1. Set an oven rack in the middle position and heat the oven to 350 degrees F. Grease a 9- by 9-inch baking pan.
2. Place a large bowl over a pan of simmering water, then melt the butter and chocolate together until smooth. Take the bowl off the heat and whisk in the salt, 3/4 cup sugar, 2 eggs, 1 teaspoon vanilla, and sour cream. Add the flour, cocoa, and baking powder, then whisk until the batter is smooth. Spoon the batter into the pan in dollops, and do not spread it out.
3. In a second large bowl, stir the cream cheese with the remaining 4 tablespoons sugar until the mixture is smooth and free of lumps. Whisk in the remaining 1 teaspoon vanilla and the remaining egg. Drop spoonfuls of the cheesecake mixture into any open spaces or gaps in the pan.
4. Use a butter knife or offset spatula to gently marble the batters together. Bake until just set, 20 to 25 minutes. Cool in the pan for 1 hour, then cut into bars and serve.
