This marble cheesecake recipe is perfect for those who love a creamy and decadent dessert. It's made with cream cheese, sugar, eggs, and vanilla extract. To make the crust, mix together graham cracker crumbs, sugar, and melted butter. Press the mixture into the bottom of a greased springform pan. To make the filling, beat cream cheese and sugar together until smooth. Then add eggs, one at a time, followed by vanilla extract. Divide the batter in half and mix cocoa powder into one half. Pour the vanilla and chocolate batter into the springform pan, alternating between the two. Use a knife to swirl the batter together to create a marble effect. Bake for 50-60 minutes at 325°F. Let the cheesecake cool before refrigerating for at least 4 hours or overnight.
