Turn the oven temperature down to 300° F.
In the bowl of a stand mixer fitted with a paddle attachment or using an electric hand mixer, cream together room temperature cream cheese, granulated sugar, brown sugar, and all-purpose flour until smooth and creamy.
Add in pumpkin puree, vanilla extract, and pumpkin pie spice and mix on low until well combined.
While mixing on low speed, drizzle in heavy cream.
Continuing to mix on low speed, add in the room temperature eggs, one at a time, mixing in between each addition. Be sure to scrape the sides and bottom of the bowl to ensure everything is well mixed.
Wrap the springform/cheesecake pan in aluminum foil, on the bottom and up the sides. We are doing this because the cheesecake will bake in a water bath and we don't want the water to leak into the cheesecake. Be sure that the foil covers up the sides and will not allow water into the springform pan.
Pour the cheesecake filling into the biscoff cookie crust and spread evenly with an offset spatula.
Place the cheesecake pan in a larger baking pan and place in the oven. Pour approximately ½ inch of water in the larger baking pan around the cheesecake to create a water bath.
Bake for 1 hour and 30 minutes, until the cheesecake appears set but also slightly jiggly in the middle.
Turn the oven off and allow the cheesecake to sit in the closed oven for 30 minutes.
After 30 minutes, open the oven door and allow the cheesecake to begin cooling in the oven for 30 minutes.
After 30 minutes, remove the cheesecake from the oven and from the water bath and allow to cool to room temperature.
Chill the cheesecake in the refrigerator for at least 6 hours or overnight.
