Preheat your oven to 325°F (163°C).
In a mixing bowl, combine graham cracker crumbs, melted butter, and sugar. Mix until well combined.
Press the crust mixture into the bottom of the springform pan evenly. Bake for 10 minutes, then remove and set aside to cool.
In another bowl, beat the softened cream cheese and sugar with an electric mixer on medium speed until smooth. Add the vanilla extract and mix until combined.
Gradually add the eggs, one at a time, mixing just enough to incorporate after each addition. Be careful not to over-mix.
Fold in the sour cream gently until fully combined.
Pour the cheesecake filling over the cooled crust and smooth the top with a spatula.
Bake the cheesecake for 50-60 minutes, or until the center is set but still slightly jiggly. Turn off the oven and crack the door, letting the cheesecake cool inside for an hour.
Once cooled, refrigerate the cheesecake for at least 4 hours or overnight for best results.
Before serving, toss the sliced strawberries with sugar and let them sit for about 10 minutes to release their juices.
Top the cheesecake with the marinated strawberries and sprinkle the strawberry crunch topping over the top just before serving.
