In the bowl of a stand mixer, add cream cheese, using the paddle attachment, process on medium speed until creamy and smooth, about 2 minutes; clean the sides and the bottom of the bowl.
While the machine is still running, slowly add sugar, a little bit at a time.
Stop the machine and add sour cream, salt and cornstarch. Process on low speed until blended before increasing back to medium again.
While the appliance is running, add eggs, one at a time, mixing well between each addition; clean the sides and the bottom of the bowl a few times.
Add vanilla extract and process until there’s no lumps and the mixture is perfectly smooth, cleaning the sides and bottom as often as needed.
Pour the filling into the prepared, cooled crust and transfer to the 350ºF preheated oven, bake for 10 minutes.
Reduce heat to 300ºF and continue baking for an additional 50 minutes or until the edges are slightly puffed.
Turn off the oven and leave the cheesecake in with the door closed, undisturbed, for 1 hour.
Remove the cake from the oven to a wire rack and allow to cool completely for at least 1 hour. While it’s still warm, run a thin knife around the edges to help release the cake later.
When the cake gets to room temperature, transfer to the fridge for a minimum of 8 hours but preferably overnight.
