📖 Instructions

1. Preheat your oven to 350°F (175°C).
2. In a medium bowl, combine 1 ½ cups of graham cracker crumbs, ¼ cup of granulated sugar, and ½ teaspoon of ground cinnamon. Whisk these dry ingredients together thoroughly.
3. Melt 6 tablespoons of unsalted butter. Pour the melted butter over the crumb mixture and mix with a fork until all crumbs are moistened and resemble wet sand.
4. Press the mixture evenly into the bottom of a 9-inch springform pan. You can use the bottom of a glass or a flat measuring cup to help compact the crust firmly.
5. Bake the crust for 8-10 minutes, or until lightly golden brown and fragrant. This pre-baking helps prevent a soggy crust.
6. Remove from oven and let it cool completely on a wire rack while you prepare the filling. Reduce oven temperature to 325°F (160°C).
7. In a heavy-bottomed saucepan, combine 1 cup of granulated sugar and ¼ cup of water. Stir gently just to moisten the sugar.
8. Place the saucepan over medium heat. Do not stir once it starts to boil. You can gently swirl the pan occasionally to ensure even cooking.
9. Watch the sugar carefully. It will dissolve, then boil, and finally begin to turn amber. This usually takes about 8-12 minutes. The edges will darken first.
10. Once the caramel reaches a rich, deep amber color (don't let it get too dark or it will taste bitter!), immediately remove it from the heat.
11. Carefully and slowly pour in ½ cup of warm heavy cream, whisking constantly. Be very careful as the mixture will bubble up violently.
12. Add 2 tablespoons of unsalted butter and ½ teaspoon of sea salt (optional, but highly recommended!). Continue whisking until the butter is fully incorporated and the sauce is smooth.
13. Transfer about ½ cup of this caramel to a small bowl and set aside to cool completely – this will be for drizzling later. Keep the remaining caramel warm or gently reheat it later before pouring over the cheesecake.
14. In a large mixing bowl, using an electric mixer on medium speed, beat four 8-ounce packages (32 oz total) of softened cream cheese until smooth and creamy, about 2-3 minutes. Make sure there are no lumps!
15. Gradually add 1 ½ cups of granulated sugar, beating until just combined. Scrape down the sides of the bowl.
16. Beat in 2 tablespoons of all-purpose flour. This helps prevent cracking.
17. Add 1 tablespoon of vanilla extract and 1 teaspoon of fresh lemon juice (the lemon juice brightens the flavor and helps cut through the richness). Beat until just incorporated.
18. Crack 4 large eggs into a separate small bowl, then add them to the cream cheese mixture one at a time, beating on low speed after each addition just until the yolk disappears. Do not overmix, as too much air can cause cracks.
19. Stir in ½ cup of sour cream or full-fat Greek yogurt by hand with a spatula until just combined. This adds moisture and a lovely tang.
20. Wrap the outside of your cooled springform pan tightly with several layers of heavy-duty aluminum foil to prevent water from seeping in during the water bath.
21. Pour the cream cheese filling over the cooled graham cracker crust in the springform pan.
22. Pour about ½ cup of the warm homemade caramel sauce (from step 2, excluding the reserved drizzling caramel) over the cheesecake filling. Using a knife or a skewer, gently swirl the caramel into the cream cheese for a marbled effect. Be careful not to swirl too much or too deeply into the crust.
23. Place the foil-wrapped springform pan into a larger roasting pan. Carefully pour hot water into the roasting pan until it comes about halfway up the sides of the springform pan. This water bath is crucial for even baking and preventing cracks.
24. Carefully transfer the roasting pan with the cheesecake to the preheated 325°F (160°C) oven.
25. Bake for 60-75 minutes. The edges should be set, but the center 2-3 inches should still have a slight jiggle when you gently shake the pan.
26. Turn off the oven, leave the cheesecake in the water bath with the oven door slightly ajar for 1 hour. This gradual cooling is another crack-prevention superpower.
27. Remove the cheesecake from the water bath and carefully remove the foil. Let it cool completely on a wire rack for another 1-2 hours at room temperature.
28. Once cooled to room temperature, cover the cheesecake with plastic wrap and refrigerate for at least 4 hours, or preferably overnight. Chilling is essential for the cheesecake to firm up and for flavors to meld beautifully.
29. Just before serving, gently run a thin knife around the edge of the cheesecake before unlocking and removing the springform rim.
30. Re-warm the reserved ½ cup of caramel sauce for drizzling (if needed) and gently pour or drizzle it generously over the top of the chilled cheesecake. You can add a sprinkle of flaky sea salt if you like a salted caramel kick.
31. Slice with a sharp knife, wiping the knife clean between each cut for perfect slices. Enjoy your show-stopping holiday dessert!
