With a hand mixer or in a stand mix using the paddle attachment, cream the cream cheese, granulated sugar and dark brown sugar for 1 minute on low speed. Then add the pumpkin puree and pumpkin spice and let it mix for 1 minute on low speed or until incorporated.
800 g full fat cream cheese, 100 g granulated sugar, 50 dark brown sugar, 425 g (1 can) pumpkin puree, 2 ½ teaspoon pumpkin spice
In a small bowl, mix together the sour cream and cornstarch until smooth. Add it to the cream cheese with the vanilla extract and let it mix on low speed until combined.
100 g sour cream 14-18%, 2 ½ tablespoon cornstarch, 2 ½ teaspoon vanilla extract
Then add two eggs at a time and let it mix on low speed until combined. Once all the eggs have mixed in, scrape down the sides of the bowl and give it a final mix to make sure all the ingredients have incorporated.
4 large eggs
Pour the cheesecake batter into the springform.
Boil water in a kettle. Place the cheesecake on the second lowest rack. Then on the lowest rack, underneath the cheesecake, place a roasting pan and fill it with the boiled water.
Bake for 1 hour and 10-15 minutes.
Once the time has passed, give the tray a very gentle shake. The cheesecake should still be a small wobble in the middle. Turn off the oven and have the oven door slightly open and let the cheesecake cool down in the oven for 1 hour.
Finally, place it in the refrigerator and let it set for at least 6 hours, preferable overnight before eating.
