# What You Need:
→ Brownie Batter
01 - 1/2 cup unsalted butter, melted
02 - 3/4 cup granulated sugar
03 - 1/2 cup light brown sugar, packed
04 - 2 large eggs
05 - 1 teaspoon vanilla extract
06 - 3/4 cup unsweetened cocoa powder
07 - 1/2 cup all-purpose flour
08 - 1/4 teaspoon salt
→ Cheesecake Swirl
09 - 8 ounces cream cheese, softened
10 - 1/4 cup granulated sugar
11 - 1 large egg
12 - 1/2 teaspoon vanilla extract
# How-To Steps:
01 - Preheat oven to 350°F. Line an 8x8-inch square baking pan with parchment paper, allowing an overhang for easy removal.
02 - In a large bowl, whisk together melted butter, granulated sugar, and light brown sugar until smooth. Add eggs and vanilla extract, whisking until glossy.
03 - Sift in cocoa powder, all-purpose flour, and salt. Stir gently until just combined without overmixing.
04 - In a separate bowl, beat cream cheese until smooth. Add sugar, egg, and vanilla extract, beating until creamy and lump-free.
05 - Pour about two-thirds of brownie batter into the prepared pan and smooth the surface. Spread cheesecake mixture evenly over the brownie layer.
06 - Dollop remaining brownie batter over the cheesecake layer. Use a knife or skewer to gently swirl the two batters together for a marbled effect.
07 - Bake for 35 to 38 minutes until the center is set but still slightly moist; a toothpick inserted should come out with a few moist crumbs. Avoid overbaking.
08 - Allow to cool completely in the pan on a wire rack. Use parchment paper to lift out and cut into 16 squares before serving.
