Preheat the oven to 390/200ºC. Line the outside of a 9-inch springform pan with a big sheet of aluminum foil and close it up, bring the foil to the upper side of the pan to prevent the water from entering.
Crush the biscoff cookies in a food processor until sandy, then add the melted butter and mix until thoroughly combined. Transfer the crumb mixture to the pan and press down firmly to make the crust. Bake for 10 minutes.
3 cups Biscoff cookie, ⅓ cup butter
Lower the oven temperature to 230F 110ºC and bring a pot of water to boil. In a big bowl, using an electric mixer, mix the cream cheese, pumpkin puree, and brown sugar until fully combined. Add the eggs one at a time and continue to mix, then add the flour and mix until just combined.
3 ½ cups cream cheese, 1 ¾ cups pumpkin puree, 1 cup brown sugar, 5 large eggs, ⅓ cup all-purpose flour
Remove the crust from the oven and allow to cool for a few minutes. Once cool, add the cream cheese mixture to the crust. Place the pan in a large baking tray and add the boiling water so it's sitting in water. Bake for 90 minutes; turn the oven off, open the oven door slightly, and prise it open with a wooden spoon. Let the cheesecake cool completely there. Transfer to the refrigerator for at least 4 hours but preferably overnight.
When ready to serve, decorate the cake with caramel sauce, crushed Biscoff cookies, icing or cream, and white chocolate chips. Serve and enjoy!
