Step 1

Preheat the oven to 350 degrees Fahrenheit (175°C) and lightly grease a 9-inch springform pan.

Step 2

In a medium bowl, combine the graham cracker crumbs and melted butter. Mix until it looks like wet sand.

Step 3

Press the crumb mixture firmly into the bottom of the prepared pan to create a tightly packed crust. Then bake for 5-8 minutes until lightly golden.

Step 4

Reduce the oven to 325°F and set the crust aside to cool.

Step 5

In a large bowl, blend the cream cheese and sugar together until smooth. Then add the eggs one at a time, mixing well between additions.

Step 6

Finally, stir in the sour cream, cornstarch, and vanilla until smooth.

Step 7

Pour the filling over the prepared crust and bake for 1 hour.

Step 8

After 1 hour, turn the oven off and leave the cheesecake to cool for 1 hour with the door open just a couple of inches.

Step 9

Take the cheesecake out of the oven and leave it to cool completely on the counter. Then wrap and refrigerate it overnight until firm.
