Preheat the oven.

In a bowl, combine graham cracker crumbs, melted butter, and 1/4 cup granulated sugar; press into the bottom of a springform pan.

In another bowl, beat cream cheese until smooth; mix in sour cream, 3/4 cup sugar, and vanilla extract.

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

Fold in crumbled churros into the cheesecake mixture.

Pour the cheesecake mixture over the crust in the springform pan.

Bake in the oven until set, about 70 minutes.

Let cool and top with cinnamon-sugar mixture before serving.
