Preheat oven to 163°C. Grease a 23 cm springform pan with butter or non-stick spray. Combine graham cracker crumbs and melted butter in a medium bowl, mixing until the texture resembles wet sand. Press mixture firmly into the base of the pan to form an even layer, using the back of a spoon or a flat-bottomed glass. Chill in the refrigerator while preparing the filling.

In a large mixing bowl, beat softened cream cheese, granulated sugar, and vanilla extract with an electric mixer on medium speed until smooth. Add eggs one at a time, mixing just until incorporated after each addition. Avoid overmixing. Gently fold in sour cream and flour until just combined.

Pour filling over chilled crust and smooth the surface with a spatula. Place pan on a baking sheet to catch drips. Bake at 163°C for 55 to 60 minutes, until edges are set and center is still slightly wobbly.

Turn off oven and leave cheesecake inside with the door slightly ajar for 1 hour to cool slowly and minimize cracking. Run a knife around the edge to loosen from the pan. Refrigerate for at least 4 hours or overnight until thoroughly chilled.

Release the springform pan sides. Transfer cheesecake to a serving platter, slice into portions, and serve plain or with preferred toppings such as fresh berries or whipped cream.
