Mix graham cracker crumbs, melted butter, and 1/4 cup of granulated sugar in a bowl, then press into the bottom of a springform pan.

In a large bowl, beat the softened cream cheese until smooth.

Add 3/4 cup granulated sugar, sour cream, vanilla extract, and eggs to the cream cheese, mixing until well combined.

Pour the cheesecake filling over the crust in the pan.

Bake in the preheated oven until set.
