Ingredients You’ll Need

Every bite of this Key Lime Cheesecake owes its dreamy flavor and luscious texture to a handful of simple yet purposeful ingredients. Each component plays a vital role—delivering creaminess, citrus punch, a delicate crunch, and that iconic sunny color.

Graham cracker crumbs: The classic base that brings a sweet, toasty crunch to every slice.
Granulated sugar: Sweetens both the crust and creamy filling without overpowering the citrus notes.
Unsalted butter, melted: Holds the crust together and adds a rich, buttery flavor profile.
Cream cheese, softened: The superstar of any cheesecake, ensuring a velvety, smooth filling.
Large eggs: Bind the mixture and deliver the perfect custardy set to the dessert.
Sour cream: Lends tang and keeps the texture ultra-silky.
Cornstarch: Prevents cracks and stabilizes the filling without heaviness.
Fresh key lime juice (or bottled): Bright, authentic key lime flavor is a must for that punchy taste.
Key lime zest: Packs in extra citrus aroma and flavor—don’t skip the zest for maximum zing!
Vanilla extract: Rounds out the tartness with a subtle creamy note.
Whipped cream and lime slices (optional): The ultimate final flourish for a bakery-worthy look and additional creaminess.

How to Make Key Lime Cheesecake

Step 1: Prepare the Crust

Begin by preheating your oven to 325°F (163°C). In a medium bowl, blend together graham cracker crumbs, 1/4 cup sugar, and melted butter until the mixture resembles wet sand. Press this delicious sandy mixture firmly into the bottom of your 9-inch springform pan—using the bottom of a glass works wonderfully for even coverage. Bake the crust for about 10 minutes, just until it’s set and lightly golden. Set aside to cool slightly while you make the filling.

Step 2: Make the Cheesecake Filling

With everything at room temperature, beat the softened cream cheese in a large mixing bowl until it’s completely smooth and free of lumps. Gradually beat in 1 cup sugar, ensuring the mixture stays creamy and well incorporated. Add the eggs one at a time, beating after each addition—this helps keep the filling airy yet sturdy. Stir in the sour cream, cornstarch, key lime juice, lime zest, and vanilla extract. The batter should look silky and lightly thickened, flecked with those gorgeous green zest bits.

Step 3: Assemble and Set Up the Water Bath

Pour the inviting key lime filling over your prepared crust, smoothing the top with a spatula. To encourage an ultra-creamy texture and prevent cracks, prepare a water bath by placing the springform pan inside a larger roasting pan. Fill the outer pan with hot water until it reaches about halfway up the sides of the cheesecake pan. This gentle method ensures even, moist heat as it bakes.

Step 4: Bake the Key Lime Cheesecake

Bake for 55–65 minutes, or until the edges are set and the center is just a bit jiggly. This gentle jiggle is your friend—it’ll firm up perfectly as it cools. Turn off the oven and crack the door, allowing the cheesecake to rest inside for an hour. This helps prevent sudden temperature changes, which can cause cracks on top.

Step 5: Cool, Chill, and Garnish

Remove your Key Lime Cheesecake and let it cool on the counter until it reaches room temperature. Once cooled, refrigerate for at least 4 hours, though overnight is best for a firm, sliceable texture. When you’re ready to serve, garnish with billows of whipped cream and dainty lime slices. Each bright, beautiful slice is a feast for the senses!

How to Serve Key Lime Cheesecake

Garnishes

The right garnish turns your Key Lime Cheesecake from delicious to downright dazzling. Try swirling generous dollops of fresh whipped cream around the edges and topping each slice with thin lime rounds or a sprinkle of zest. The creamy contrast and pop of color make every serving special.

Side Dishes

Pair your cheesecake with a simple berry salad—think strawberries, blueberries, or raspberries tossed in a light honey-lime syrup. The juicy berries brighten each bite and keep things feeling light, while a hot cup of coffee or iced tea balances out the sweet-tart flavors beautifully.

Creative Ways to Present

Want to wow a crowd? Cut petite cheesecake squares and serve them on a platter with mini forks for an elegant dessert buffet. Or, portion into parfait glasses layered with crushed graham crackers and a dollop of whipped cream for an easy, no-fuss party treat. You can even decorate with edible flowers or candied lime peel for an extra-special flourish.

Make Ahead and Storage

Storing Leftovers

Cover your Key Lime Cheesecake tightly with plastic wrap or store in an airtight container in the refrigerator. It will stay lusciously fresh for up to 5 days without losing its creamy texture or citrusy punch—just be sure to enjoy a chilled slice when you get the craving!

Freezing

If you’d like to make your cheesecake ahead or save leftovers for later, simply freeze individual slices (or the whole cake) wrapped snugly in plastic wrap, then foil. Cheesecake freezes surprisingly well for up to 2 months—just thaw overnight in the fridge before serving to let those flavors perk up again.

Reheating

Since Key Lime Cheesecake is best enjoyed cold, there’s no need to reheat. However, if you’ve frozen your cake, make sure to let it thaw gradually in the refrigerator to maintain its smooth and creamy texture. Avoid microwaving to keep it from becoming rubbery.

FAQs

Can I use regular limes instead of key limes?

While regular limes can step in for a similar flavor, authentic key limes have a unique tart-sweet taste and aromatic zest that truly makes this cheesecake shine. If you can find key limes or bottled key lime juice, it’s worth the effort!

What if I don’t have a springform pan?

You can use a deep-dish pie pan as an alternative—just be aware that releasing the cheesecake might be trickier. Lining the pan with parchment overhang can help you lift out neat slices.

How do I prevent cracks on the surface?

Using a water bath and allowing the cheesecake to cool gradually in the oven greatly reduces the risk of cracks. Also, don’t overmix the batter or open the oven door during baking—steady heat is key.

Can I make Key Lime Cheesecake in advance?

Absolutely! This dessert is a fantastic make-ahead option. In fact, Key Lime Cheesecake tastes even better after a day in the fridge as the flavors have time to meld and deepen.

Do I have to use cornstarch?

Cornstarch helps set the filling and prevents surface cracks, but you can leave it out if you prefer a lighter, creamier texture—just expect a softer set and slice gently with a warm knife.

Final Thoughts

If you’re dreaming of a dessert that combines creamy decadence with a burst of citrus sunshine, look no further than this Key Lime Cheesecake. Give it a try, share it with friends and family, and watch it disappear slice by slice. I’m confident it’ll become one of your most-requested treats!
