Blend until completely smooth. You may need to stop and scrape the sides, you want to make sure there are no lumps of cream cheese that have settled on the sides or bottom.
Transfer to 325F (165C) preheated oven and bake for 35 mins. Once time has elapsed, do not open the oven but increase oven temperature to 500F (260C) and bake for 5-10 mins.
Remove from oven, it should still be extremely jiggly. Allow to cool to room temperature then transfer to refrigerator to chill overnight or for at least 5 hours before enjoying.
