Place the softened cream cheese to the bowl of a stand mixer and beat for about 4 minutes until it is smooth and creamy.
Add the sugar to the cream cheese and beat for another 3 minutes.
Next, add the vanilla and eggs, one at a time, beating for 1 minute in between each addition.
Mix in the pumpkin puree and pumpkin spice, mixing just until combined.
Gently add the sour cream followed by the heavy cream.
Pour the cheesecake batter into the springform pan then place the pan into the roasting pan filled with enough hot water to go half way up the side.
Bake the cheesecake in the water-filled roasting pan at 325 degrees for 90 minutes.
When the cheesecake has finished baking, prop open the oven door and allow the cheesecake to cool in the over for one hour. This will help prevent the cheesecake from cracking.
Remove the cheesecake from the oven and from the roasting pan and cover it loosely with foil. Refrigerate it for at least 4 hours, but overnight is best.
