Preheat your oven to 350 degrees Fahrenheit. Line the bottom of a 9 inch spring form pan with parchment paper and spray the sides of the pan lightly with cooking spray. Set aside. Combine the graham cracker crumbs, melted butter, and sugar together in a bowl until it resembles wet sand. Press the mixture into the bottom of the spring form pan. Bake for 6 to 8 minutes or until the crust is golden brown.
1 3/4 cup graham cracker crumbs, 8 tablespoons unsalted butter, 1/3 cup granulated sugar
In a large bowl with a hand mixer or in the bowl of a stand mixer with the paddle attachment, blend the cream cheese and sugar until it is smooth.
24 ounces cream cheese, 3/4 cup granulated sugar
Mix in the eggs one at a time, flour, lime zest, and key lime juice. Scrape down the sides as needed until the mixture is smooth and well combined. 3 large eggs, 2 tablespoons all-purpose flour, 1 1/2 tablespoons lime zest, 1 1/2 tablespoons key lime juice
When the crust is done baking, turn the oven down to 325 degrees Fahrenheit. Pour the mixture over the hot crust.
Bake the cheesecake for 35 minutes. Turn the oven off, without opening it, and leave the cheesecake in the oven for 1 hour. Remove the cheesecake from the oven. Allow it to cool before moving it to the refrigerator to chill for at least 4 hours.
When ready to serve, carefully remove the sides of the springform pan and pipe the whipped cream on top. Sprinkle with more lime zest, slice, and enjoy. 1/2 cup stabilized whipped cream
