# What You’ll 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 oz cream cheese, softened
10 - 1/4 cup granulated sugar
11 - 1 large egg
12 - 1/2 teaspoon vanilla extract
# Step-by-Step:
01 - Preheat oven to 350°F. Line an 8x8-inch square baking pan with parchment paper, leaving 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, flour, and salt. Stir gently until just combined—do not overmix.
04 - In a separate bowl, beat the cream cheese until smooth. Add sugar, egg, and vanilla extract. Beat until creamy and lump-free.
05 - Pour about 2/3 of the brownie batter into the prepared pan and smooth the top. Gently spread the cheesecake batter over the brownie layer.
06 - Dollop the 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 35–38 minutes, or until the center is just set and a toothpick inserted comes out with a few moist crumbs.
08 - Cool completely in the pan on a wire rack before lifting out and cutting into squares.
