In a bowl, combine graham cracker crumbs, 3 tablespoons sugar, and butter. Press onto the bottom of a 9-inch springform pan.
Using a stand mixer or electric hand mixer, beat cream cheese, 1 cup sugar, and vanilla extract on high speed until blended. Add eggs, 1 at a time, mixing on low speed after each, just until combined. Add and blend in lime juice.
Pour cheesecake filling over the crust.
Bake for 55 minutes, or until the center is slightly jiggly, but almost set. Run a knife around the rim of the pan to loosen the cake, but do NOT remove the rim yet.
Refrigerate the cheesecake in the pan for 4 hours. Remove from the fridge and set pan on a serving platter. Unlatch and remove the springform pan.
In a tall bowl (I use an 8-cup liquid measuring cup) or bowl of stand mixer, use a hand or stand mixer on high speed to whip the heavy cream with the powdered sugar and vanilla extract. Whip until stiff peaks form.
Spread the whipped cream on top of the chilled cheesecake.
Top with lime zest, slice and serve!
Notes
Substituting Lime Juice for Key Lime JuiceYou can substitute lime juice for key lime juice equally, at a ratio of 1:1.Keep in mind though, lime juice tastes a bit different than key limes, so the dish may not taste quite the same. If you’re using regular limes and want to improve the flavor, you could add a teaspoon or so of lime zest as well.
