Preheat the oven to 325°F and spray a 9x13-inch baking dish with baking spray.

In a mixing bowl, combine graham cracker crumbs, sugar, and melted butter. Mix well and press evenly into the bottom of the prepared baking dish.

In a stand mixer, beat the softened cream cheese and sugar on high speed until light and fluffy, about 3 minutes.

Reduce mixer speed to medium. Add the eggs, sour cream, and vanilla extract, mixing until smooth.

Spread the cheesecake mixture over the prepared crust. Bake for 40-45 minutes until the edges are set and the center is slightly jiggly.

Let the dish cool to room temperature before refrigerating. Chill completely before cutting into squares.
