In a large bowl, beat the cream cheese and sugar until smooth, about 3-4 minutes on medium speed.
3 (8-ounce) pkgs. cream cheese, 1 1/2 cups light brown sugar
Add pumpkin puree, sour cream, flour, vanilla, cinnamon, ginger, nutmeg, and cloves. Mix well, scraping the bottom and sides of the bowl to make sure everything is evenly combined.
1 (15-ounce) can pumpkin puree, 1/3 cup sour cream, 2 Tablespoons all-purpose flour, 1 Tablespoon vanilla extract, 1/2 teaspoon ground cinnamon, 1/4 teaspoons ground ginger, 1/8 teaspoon ground nutmeg, 1/8 teaspoons ground cloves
Add the eggs and mix again on low speed just until combined.
4 large eggs
Pour filling into the prepared crust. If using the water bath approach, wrap the bottom of the springform pan in a slow cooker liner and/or heavy duty aluminum foil. Set the springform pan in a larger roasting pan and carefully fill around the springform pan with at least an inch of hot water.
Transfer the cheesecake to the oven and bake for 60 minutes until the outside of the cheesecake is set but the center is still wobbly. Turn off the oven, but leave the cheesecake inside with the oven door closed while it cools slowly for 45 minutes.
Remove the cheesecake from the oven (and from the water bath, if you opted to use one) and cool on the counter until room temperature. Transfer the cooled cheesecake to the fridge to chill for at least 4 hours or overnight before slicing and serving with freshly whipped cream swirls piped on top.
