Preheat the oven.

In a mixing bowl, combine graham cracker crumbs, melted butter, and sugar; press mixture into the bottom of a springform pan to form the crust.

In another bowl, beat cream cheese until smooth; gradually add granulated sugar, sour cream, and vanilla extract, mixing until well combined.

Add eggs one at a time, mixing well after each addition.

Pour the cream cheese mixture over the crust in the springform pan.

Bake in the preheated oven for 60 minutes or until set.

Brush the top of the cheesecake with melted butter and sprinkle with cinnamon sugar mixture.

Allow to cool before serving.
