Preheat the oven to 350°F (175°C). Line an 8×8-inch baking pan with parchment paper, allowing overhang for easy removal.
02 -
Combine butter and dark chocolate in a microwave-safe bowl. Microwave in 30-second increments, stirring between each, until melted and smooth. Set aside to cool slightly.
03 -
Whisk granulated sugar and brown sugar into the melted chocolate mixture until fully blended. Add eggs one at a time, beating well after each addition.
04 -
Sift in all-purpose flour and cocoa powder. Gently fold into the chocolate base with a spatula until just combined and no dry pockets remain. Stir in vanilla extract.
05 -
In a separate mixing bowl, beat softened cream cheese and granulated sugar until smooth and creamy. Add the egg, followed by heavy cream and vanilla extract, mixing until fully combined.
06 -
Pour brownie batter evenly into the prepared pan. Carefully spread the cheesecake mixture over the brownie base.
07 -
Use a knife or toothpick to gently swirl the cheesecake and brownie layers together for a marbled pattern, if desired.
08 -
Bake for 35 to 40 minutes or until the edges are firm and the center is just set but still slightly jiggly. Avoid overbaking for optimal texture.
09 -
Allow the cake to cool completely at room temperature. Transfer to the refrigerator and chill for at least 2 hours or overnight for clean slicing and best texture.

Remove the cake from the pan using parchment overhang. Slice into squares and serve chilled. Optionally, garnish with melted chocolate or whipped cream and fresh berries.
