There’s something deeply nostalgic about citrus desserts—like the way a single bite can bring you back to long, sun-drenched summer afternoons, or family gatherings where someone always arrived with a creamy, tangy dessert that stole the show. That’s the charm of Key Lime Cheesecake.

This dessert is a dreamy marriage between the tart, tropical zing of key limes and the rich, velvety texture of cheesecake. Originating from the sunny Florida Keys, where the tiny, aromatic key limes grow abundantly, this flavor has become a symbol of warmth, coastal comfort, and celebration.

I remember the first time I tasted a homemade key lime dessert—it was at a beachside family reunion where my aunt had lovingly prepared a cheesecake that everyone raved about. That cheesecake had a vibrant lime kick, a buttery crust that melted in your mouth, and a fluffy topping that felt like a cloud. Ever since, it’s become my go-to when I want to bring a little sunshine into the kitchen, especially in spring and summer when the craving for something light, bright, and creamy hits just right.

So whether you’re planning a backyard barbecue, looking for a stunning dessert for Easter brunch, or just need a cheerful treat for a rainy day, this Key Lime Cheesecake is your ticket to tropical bliss.

INGREDIENTS YOU’LL NEED:

For the Crust:

• 1 ½ cups graham cracker crumbs
• ¼ cup granulated sugar
• 6 tablespoons unsalted butter, melted

For the Cheesecake Filling:

• 3 (8-ounce) packages cream cheese, softened
• 1 cup granulated sugar
• 3 large eggs
• ½ cup sour cream
• ⅔ cup key lime juice
• 1 tablespoon key lime zest
• 1 teaspoon vanilla extract

For the Topping:

• 1 cup heavy whipping cream
• 2 tablespoons powdered sugar
• ½ teaspoon vanilla extract
• Lime slices or zest for garnish (optional)

HOW TO MAKE KEY LIME CHEESECAKE:

STEP-BY-STEP INSTRUCTIONS:

Step 1: Make the Crust
Start by preheating your oven to 325°F (163°C). In a medium bowl, mix together the graham cracker crumbs, sugar, and melted butter until everything is well combined. It should feel like damp sand and hold together when pressed.

Press the mixture firmly into the bottom of a 9-inch springform pan. You can use the bottom of a glass or measuring cup to help press it evenly. Bake the crust for 10 minutes, then set it aside to cool while you prepare the filling.

Step 2: Mix the Cheesecake Filling
In a large bowl or stand mixer, beat the softened cream cheese until smooth and creamy—no lumps! Add the granulated sugar and mix until fully incorporated.

Next, add the eggs one at a time, beating well after each addition. Stir in the sour cream, key lime juice, zest, and vanilla. The batter should be smooth and slightly tangy—go ahead and sneak a taste!

Step 3: Bake the Cheesecake
Pour the cheesecake filling into the cooled crust and smooth out the top. Give the pan a gentle tap on the counter to release any air bubbles.

Place the springform pan into a larger roasting pan and carefully pour hot water into the roasting pan, about halfway up the sides of the springform. This water bath helps the cheesecake bake evenly and prevents cracking.

Bake for 55–65 minutes, or until the center is just slightly jiggly and the edges are set. Turn off the oven and crack the door slightly, letting the cheesecake cool in the oven for 1 hour.

Step 4: Chill Completely
Once cooled, transfer the cheesecake to the fridge and chill for at least 4 hours, but overnight is best. The flavor deepens and the texture becomes even silkier.

Step 5: Whip the Topping
Before serving, whip the heavy cream with powdered sugar and vanilla until soft peaks form. Spread or pipe it over the top of the cheesecake. Garnish with lime zest or thin lime slices for an extra pop of citrusy charm.

HELPFUL TIPS:

• Use fresh key lime juice if you can: It has a more floral and tangy flavor than regular limes. Bottled key lime juice works in a pinch, though!
• Don’t skip the water bath: It makes all the difference for that creamy, crack-free surface.
• Room temperature ingredients = smoother filling: Make sure the cream cheese, eggs, and sour cream are all at room temp before mixing.
• Let it chill fully: The longer it chills, the better it sets and tastes.

FREQUENTLY ASKED QUESTIONS:

Can I use regular limes instead of key limes?
Yes! While key limes have a distinct flavor, regular Persian limes work just fine if that’s what you have.

What if I don’t have a springform pan?
You can use a deep pie dish, though you may need to adjust baking times and skip the water bath. Keep an eye on the center for doneness.

How do I know when the cheesecake is done?
The center should jiggle slightly like gelatin, while the edges are set. Don’t overbake—it continues to set as it cools!

STORAGE INSTRUCTIONS:

Keep leftover cheesecake covered in the fridge for up to 5 days. You can also freeze it (without whipped topping) for up to 2 months. Thaw overnight in the fridge and add the whipped cream just before serving.
