Ensure the cream cheese is very soft. The best way to do this is to microwave it for about 15 seconds.
In a large mixing bowl, beat the softened cream cheese until smooth. This step is crucial for achieving the perfect creamy texture.
Add the pumpkin puree, eggs, sour cream, sugar, cinnamon, nutmeg, cloves, flour, and vanilla. Mix until fully combined and smooth.
Pour the filling into the prepared crust and smooth the top with a spatula.
Place the pan (and baking sheet it's sitting on) into the oven.
Once it's in the oven, pour boiling water into the baking sheet until it reaches to the top of the baking sheet (not spilling over) This water bath will help the cheesecake bake evenly and prevent cracks.
Bake the cheesecake for 1 hour.
After baking, turn off the oven, prop the door open slightly, and allow the cheesecake to rest in the oven for another hour.
Remove the cheesecake from the oven and refrigerate for at least 4 hours, or overnight, for best results.
