# 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 ounces cream cheese, softened
10 - 1/4 cup granulated sugar
11 - 1 large egg
12 - 1/2 teaspoon vanilla extract
# How to Make:
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 melted butter, granulated sugar, and brown sugar until smooth. Add eggs and vanilla; whisk until glossy.
03 - Sift cocoa powder, flour, and salt into the wet mixture. Stir gently until just combined, avoiding overmixing.
04 - In a separate bowl, beat cream cheese until smooth. Add sugar, egg, and vanilla; beat until creamy and lump-free.
05 - Pour about two-thirds of the 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 both batters together for a marbled effect.
07 - Bake for 35 to 38 minutes, until the center is just set and a toothpick inserted comes out with moist crumbs; do not overbake.
08 - Cool completely in the pan on a wire rack before lifting out using parchment overhang and cutting into 16 squares.
