While the water is boiling, pour the filling mixture into the buttered, cooled, and foiled springform pan.
Place the cheesecake in the center of the roasting pan in the oven. Carefully pour the boiling water into the roasting pan until it comes halfway up the sides of the springform pan.
Bake at 325°F for 1 hour and 15 minutes.
After 1 hour and 15 minutes, turn off the oven and open the oven door slightly to let out some heat. Place a wooden spoon in the oven door to keep it slightly propped open. Leave the cheesecake inside for 1 more hour.
After an hour, remove the cheesecake and let it cool on a cooling rack. Once cooled, run a knife along the edges to loosen it and cover it with plastic wrap. Place it in the fridge overnight.
