Add the cream cheese (16 oz) and granulated sugar (⅔ cup) to a large bowl. Using a hand mixer, mix on medium speed for about 2-3 minutes, or until smooth and creamy.
Add the sour cream (⅓ cup), vanilla extract (1 Tbsp), and 2 eggs to the filling, and mix on medium speed until all of the ingredients are evenly mixed and creamy. Don't overmix.**
Pour the cheesecake filling into the metal pan over the churro crust. Smooth the top with a rubber spatula so that the top is level. Bake for about 35-40 minutes, until the center is set.
Remove the cheesecake from the oven and let it cool to room temperature. Then cover the cheesecake and refrigerate it overnight (or at a MINIMUM of 4 hours).
