Preheat the oven to 325°F (160°C).
In a mixing bowl, combine the graham cracker crumbs, melted butter, and sugar. Press the mixture firmly into the bottom of the springform pan to form an even layer.
In another large mixing bowl, beat the softened cream cheese until smooth with an electric mixer. Gradually add sugar and mix until combined.
Add in the eggs one at a time, mixing well after each addition. Then add vanilla extract, sour cream, and flour. Mix until smooth and well blended.
Pour the cheesecake batter over the prepared crust in the springform pan, spreading it evenly.
Bake in the preheated oven for 60 minutes or until the edges are set and the center is slightly jiggly. Turn off the oven and let the cheesecake cool in the oven with the door slightly ajar for about 1 hour.
In a food processor, pulse the freeze-dried strawberries until crushed. In a bowl, mix together the crushed strawberries, crushed graham crackers, melted butter, and sugar until well combined.
Once the cheesecake has cooled, sprinkle the strawberry crunch topping generously over the top.
Refrigerate the cheesecake for at least 4 hours or overnight to set.
Slice and serve chilled. Enjoy!
