Pour the remaining batter evenly out overtop and smooth out in an even layer. Gently tap the pan against a flat countertop to remove any trapped air bubbles.
Bake for 55-65 minutes, just until the edges are set but the center's still a but jiggly. Turn off the oven, crack the door, and let the cheesecake sit in the oven for 45 more minutes.
Transfer the cheesecake to the refrigerator and chill for at least 4 hours, or up to overnight.
