Preheat your oven to 325°F (160°C).
In a bowl, combine graham cracker crumbs and melted butter. Press into the bottom of a springform pan to form the crust.
In a large mixing bowl, beat the cream cheese and sugar until smooth.
Add sour cream and vanilla extract, mixing until combined.
Add eggs one at a time, blending on low speed until just incorporated.
Pour the batter over the crust and smooth the top.
Bake for 50-60 minutes or until the center is set. Cool to room temperature, then refrigerate for at least 4 hours or overnight before serving.
