Preheat your oven to 325°F and grease a 9-inch springform pan with butter or cooking spray. While the oven heats, combine the finely crushed gingersnap cookies, melted salted butter, and 1 tablespoon sugar in a bowl, mixing until the texture resembles wet sand. Press this mixture firmly into the bottom of your prepared pan, creating an even, compact layer. Bake the crust for 6 minutes until it’s set and slightly golden, then remove it and let it cool while you prepare the filling. I like to use Kerrygold salted butter here because its rich flavor complements the spices beautifully.

Ensure your cream cheese is at room temperature (about 70°F) for the smoothest, lump-free filling. Beat the cream cheese in a large bowl with an electric mixer on medium speed for 2-3 minutes until it’s completely smooth and creamy, scraping down the bowl as needed. Add the white sugar and packed brown sugar, mixing for another minute until well combined. Pour in the vanilla extract and pumpkin puree, mixing on low speed just until fully incorporated. The pumpkin should be evenly distributed throughout, creating a uniform orange base.

Sprinkle the ground cinnamon, ground nutmeg, and ground cloves directly into the filling and mix gently on low speed until the spices are evenly distributed. Add the room temperature sour cream and fold it in carefully, mixing only until combined. I prefer using freshly ground cinnamon when I can because it gives the cheesecake noticeably more aromatic depth than pre-ground spices. Be careful not to overmix at this stage, as excessive stirring can incorporate too much air into the filling.

Whisk the 3 large eggs in a separate bowl until well combined and no streaks of white remain. Pour the whisked eggs into the filling mixture and fold gently with a rubber spatula, mixing just until the eggs are fully incorporated and no streaks are visible. Stop mixing as soon as the eggs disappear—overmixing at this point introduces air bubbles that can cause cracks. Pour the batter over the cooled crust in your springform pan and tap the pan gently against the counter a few times to release any trapped air bubbles.

Wrap the outside of your springform pan completely with aluminum foil to prevent water from seeping in during the water bath. Heat 4 quarts of water until it’s steaming hot. Place your wrapped springform pan into a roasting pan, then carefully pour the hot water into the roasting pan until it reaches halfway up the sides of the springform pan. The water bath ensures gentle, even heat distribution, preventing the cheesecake from cracking. Carefully place the entire setup into your preheated 325°F oven.

Bake the cheesecake for 65 minutes. The cheesecake is done when the edges are set but the center still jiggles very slightly when gently shaken—it should look nearly set but not completely firm. Turn off the oven without opening the door and let the cheesecake sit undisturbed in the warm oven for 5 hours. This gentle cooling process prevents the dramatic temperature shock that causes cracking. After 5 hours, carefully remove the cheesecake and roasting pan from the oven and allow it to cool to room temperature.

Remove the foil from the springform pan and transfer the cheesecake to the refrigerator to chill overnight (at least 8 hours, preferably 12 hours). This chilling time allows the flavors to meld and the texture to set completely. The next day, run a thin knife around the edges of the pan before unspringing to make removal easier and prevent cracking. Serve chilled, optionally topped with whipped cream or a drizzle of caramel sauce.
