Preheat your oven to 325°F (160°C).
Mix crushed graham crackers, melted butter, sugar, and cinnamon until combined.
Press the mixture firmly into the bottom of a springform pan to form the crust.
Beat the softened cream cheese until smooth in another bowl.
Add sugar and vanilla extract, mixing well until combined.
Add eggs one at a time, mixing on low speed after each addition.
Fold in sour cream gently until the mixture is smooth.
Pour the cheesecake filling over the crust in the springform pan.
Bake for 55-60 minutes, or until the center is set but slightly jiggly.
Prepare churros by boiling water and butter, then adding flour, salt, and vanilla.
Pipe churro shapes onto a baking sheet and sprinkle with cinnamon sugar; bake until golden.
Once cooled, top the cheesecake with churros and drizzle with chocolate sauce.
