In a medium bowl, combine the graham cracker crumbs and melted butter until crumbly. Press the mixture firmly into the bottom of a 9-inch springform pan to form the crust. Bake for 10 minutes, then remove and let cool.
In a large bowl, beat the softened cream cheese with an electric mixer until smooth and creamy. Add the granulated sugar and continue beating until well combined.
Mix in the vanilla extract and eggs, one at a time, ensuring each is fully incorporated before adding the next.
Gently fold in the melted white chocolate until evenly mixed.
In a small bowl, combine the sour cream with cornstarch and add it to the cheesecake mixture, mixing until smooth.
Gently fold in the fresh raspberries, being careful not to break them up too much.
Pour the cheesecake batter over the cooled crust in the springform pan. Spread the top evenly with a spatula.
Bake in the preheated oven for about 50-60 minutes or until the edges are set and the center is slightly jiggly.
Turn off the oven and leave the cheesecake inside with the door ajar for an hour to cool gradually, which helps prevent cracking.
Once cooled, refrigerate the cheesecake for at least 4 hours, or overnight for the best flavor.
Before serving, garnish with additional fresh raspberries and optionally some shaved white chocolate on top for an elegant touch.
Notes
For best flavor, refrigerate overnight.
