This marble cheesecake recipe is a rich and decadent dessert option that is perfect for a dinner party. The cheesecake is made with a combination of cream cheese, sugar, and eggs, and is flavored with vanilla and cocoa powder. The marble effect is created by swirling together the two batters, and the cheesecake is finished with a drizzle of chocolate sauce. Serve with fresh berries for a pop of color and flavor.
