How to Make Key Lime Cheesecake Recipe

1. Prepare the pan: Grease a 9-inch spring form pan lightly and wrap the outside with foil if you plan to use a water bath.
2. Make the crust: Mix graham cracker crumbs, melted butter, and sugar until the texture looks like wet sand. Press the mixture firmly into the bottom of the pan and slightly up the sides.
3. Prebake the crust: Bake the crust at 325°F (163°C) for 8 to 10 minutes, then let it cool while you make the filling.
4. Mix the filling: In a large bowl, beat the softened cream cheese, sugar, cornstarch, and lime zest until smooth. Add the eggs one at a time, mixing on low speed just until incorporated.
5. Add the remaining ingredients: Mix in the key lime juice, vanilla, and sour cream until the batter is smooth. Do not over mix.
6. Fill the pan: Pour the filling over the crust and smooth the top gently.
7. Bake: Bake for 55 to 65 minutes, or until the edges are set and the center still has a slight wobble.
8. Cool gradually: Turn off the oven, crack the oven door open, and let the cheesecake sit inside for 30 minutes. Then remove it and let it cool at room temperature.
9. Chill: Refrigerate for at least 8 hours or overnight before slicing.
10. Garnish and serve: Top with whipped cream and lime slices if desired, then slice with a warm clean knife.

Serving Ideas

This key lime cheesecake recipe is delicious on its own, but it looks even better with a small swirl of whipped cream and fresh lime zest on top. For a full dessert spread, serve it alongside other baking recipes, a light fruit dessert, or simple coffee after dinner.

Storage

Because cheesecake is a dairy based dessert, store this key lime cheesecake recipe covered in the refrigerator. For the best texture, chill it well before serving and keep leftovers cold. See the Cold food storage chart for safe storage guidance for chilled desserts.

Variations

FAQ

Can I use regular lime juice instead of key lime juice?

Yes. The flavor will be slightly different, but regular fresh lime juice still works well in this key lime cheesecake recipe if key limes are hard to find.

How do I keep cheesecake from cracking?

Do not over mix the batter, avoid over baking, and let the cheesecake cool gradually. A water bath or a pan of hot water in the oven can also help create a gentler baking environment.

Can I make this key lime cheesecake recipe ahead of time?

Yes. This cheesecake is actually better when made ahead because the long chill time helps the texture set properly and gives the flavors time to develop.

Can I freeze cheesecake?

Yes. Chill the cheesecake fully first, then wrap slices well and freeze them. Thaw overnight in the refrigerator before serving.

What topping goes best with key lime cheesecake?

Whipped cream, lime zest, and thin lime slices are the easiest classic toppings. A little toasted coconut also works beautifully if you want a tropical touch.
