Preheat the oven to 325F. Prepare a springform pan with cooking spray and/or parchment, see note below.
In a small bowl, combine the crust ingredients: melted butter, sugar, and graham crackers crumbs. Press the crust mixture firmly into the bottom of the prepared pan, pushing a little bit of the crust up the sides if you’d like (this is a personal aesthetic choice, go where the spirit leads you).
Separately, mix the filling ingredients (cream cheese, eggs, sugar, vanilla, salt) with a mixer on medium speed until combined and very smooth. Pour the cream cheese mixture over the crust.
Bake the cheesecake for 55-70 minutes (see note on timing) until just barely jiggly in the center.
While the cheesecake bakes, whisk together the sour cream, sugar, and vanilla for the topping.
Remove the cheesecake from the oven and let rest for 10 minutes (leave the oven on). This is an important step to let the cheesecake naturally deflate.
After 10 minutes, spread the sour cream topping evenly on the cheesecake. Return to the oven and bake the cheesecake for 10 minutes more, then carefully remove from the oven.
Let the cheesecake cool on the counter in the pan (do not remove the pan ring until ready to serve to allow the cheesecake to set properly) for at least 2 hours, and then move to the fridge for at least 4. Preferably, cool on the counter for several hours and then in the fridge overnight.
Remove the outer ring from the springform pan before serving. Slice, serve, devour. You did it!
