Preheat the oven to 325°F (160°C).
In a mixing bowl, combine crushed vanilla wafers or graham crackers, melted butter, and sugar for the crust. Press the mixture into the bottom of a springform pan.
In another bowl, beat softened cream cheese and granulated sugar until smooth. Add eggs one at a time, mixing well after each addition. Stir in vanilla extract and sour cream.
Pour the cheesecake filling over the crust and smooth the top. Bake for 50-60 minutes or until the center is set and slightly jiggly.
