Follow this easy process to create your Key Lime Cheesecake:

1. Preheat the Oven: Preheat your oven to 325°F (160°C).
2. Prepare the Crust: In a medium bowl, combine the graham cracker crumbs, granulated sugar, and melted butter. Mix well until the crumbs are evenly coated.
3. Press the Crust: Firmly press the crust mixture into the bottom of a 9-inch springform pan. Use the back of a measuring cup or your fingers for an even layer.
4. Bake the Crust: Bake the crust for 10 minutes in the preheated oven, then remove and let it cool while preparing the filling.
5. Make the Filling: In a large mixing bowl, beat the softened cream cheese and granulated sugar together until smooth and creamy.
6. Add the Flour: Mix in the flour until well combined.
7. Incorporate the Eggs: Add eggs one at a time. Beat well after each addition to ensure a smooth mixture.
8. Add Sour Cream: Mix in the sour cream until combined.
9. Flavor with Lime: Stir in the freshly squeezed key lime juice and lime zest until smooth and well incorporated.
10. Transfer to Pan: Pour the cheesecake filling over the cooled crust, spreading it evenly.
11. Bake the Cheesecake: Bake for 60 minutes, or until the center is set but still slightly jiggly.
12. Cool Down: Turn off the oven and crack the oven door, letting the cheesecake cool completely in the oven. This helps prevent cracking.
13. Chill the Cheesecake: Once cooled, refrigerate the cheesecake for at least 4 hours or overnight for the best texture.
14. Prepare to Serve: Just before serving, garnish with whipped cream, additional lime slices, and a sprinkle of lime zest.

With these straightforward steps, you’ll create a magnificent Key Lime Cheesecake that is sure to wow!
