Ingredients for Key Lime Cheesecake
Creating a delicious key lime cheesecake starts with the right ingredients. Let’s break it down!
Graham Cracker Crust Ingredients
For that perfect, sweet crust, you’ll need:
- 1 and ½ cups (180g) graham cracker crumbs (about 12 full-sheet graham crackers)
- 5 tablespoons (71g) unsalted butter, melted
- ¼ cup (50g) granulated sugar
The graham cracker crumbs give the cheesecake a delightful crunch, while the melted butter and sugar bind it together beautifully.
Cheesecake Ingredients
The creamy filling is made up of:
- 32 ounces (904g) full-fat brick PHILADELPHIA cream cheese, softened to room temperature
- 1 cup + 2 tablespoons (225g) granulated sugar
- ½ cup (120ml) key lime juice
- ⅓ cup (80g) sour cream or plain yogurt, at room temperature
- 1 teaspoon pure vanilla extract
- 2 teaspoons key lime zest
- 3 large eggs, at room temperature
This combination ensures a rich and zesty flavor that screams summer!
Optional Toppings
While the cheesecake is fabulous on its own, consider enhancing it with:
- Homemade whipped cream
- Fresh berries for a burst of flavor
- Key lime or regular lime slices for added zest
These toppings will take your key lime cheesecake to the next level and impress your guests with your culinary skills!
Step-by-Step Preparation for Key Lime Cheesecake
Creating a luscious key lime cheesecake can feel like a daunting task, but breaking it down into manageable steps makes it a piece of cake! Here’s how you can prepare this delightful dessert in just a few simple stages.
Prepare the Crust
First things first, the crust is the foundation of your cheesecake, and it’s easier than you think.
- Start by preheating your oven to 350°F (177°C). This will get it nice and warm for your cheesecake later.
- If you have whole graham crackers, crush them using a food processor until fine. Otherwise, pre-packaged crumbs will work just fine too!
- In a medium bowl, mix together 1 and ½ cups of graham cracker crumbs, 5 tablespoons of melted unsalted butter, and ¼ cup of granulated sugar until it resembles a sandy texture.
- Press this mixture firmly into the bottom (and a bit up the sides) of a 9-inch springform pan. A flat-bottomed measuring cup can help pack it tightly.
- Pre-bake the crust for about 10 minutes, then let it cool while you whip up the filling.
Make the Cheesecake Filling
For the filling, you’ll want to create a smooth and creamy consistency that’s bursting with key lime flavor.
- In a large bowl, blend 32 ounces of softened cream cheese and 1 cup + 2 tablespoons of sugar using a handheld or stand mixer on medium-high speed until it's smooth (about 2 minutes).
- Add ½ cup of key lime juice, ⅓ cup of sour cream, 1 teaspoon of vanilla extract, and 2 teaspoons of lime zest. Mix until fully combined.
- Carefully add 3 large eggs, one at a time, blending just until incorporated after each addition. Over-mixing can lead to cracks in your cheesecake, so keep it gentle!
Prepare the Water Bath
This step is essential for achieving a creamy texture without cracks.
- While preparing the cheesecake filling, boil some water (about 1 inch deep is all you need).
- Place a large metal roasting pan on the bottom oven rack and pour in the boiling water.
- Just after placing your filled cheesecake on the center rack, close the oven door to trap steam, adding moisture to the baking process.
Bake the Cheesecake
Time to let the magic happen!
- Bake the cheesecake for 55–70 minutes. It’s done when the center appears slightly wobbly—this will firm up as it cools.
- If the top starts browning too fast, cover it with aluminum foil halfway through.
Cool and Refrigerate the Cheesecake
Cooling is key for the perfect key lime cheesecake.
- Once baked, turn off the oven and crack the door open. Let it sit in the oven for another hour.
- After an hour, cool the cheesecake at room temperature, then refrigerate for at least 4 hours or, ideally, overnight.
Serve and Enjoy
The moment of truth is here!
- Carefully remove the springform pan and if you like, top with whipped cream, fresh berries, or lime slices for a lovely presentation.
- For neat slices, clean your knife after each cut and even dip it in warm water for nice, clean edges.

Variations on Key Lime Cheesecake
No-Bake Key Lime Cheesecake
If you’re short on time or just prefer a chilled dessert, a no-bake key lime cheesecake is a fantastic option. Simply whip together softened cream cheese, sweetened condensed milk, and fresh key lime juice. Pour the filling over a simple crumb crust, refrigerate for a few hours, and you’re ready to impress guests with a creamy, zesty delight. For added flair, consider topping it with homemade whipped cream and fresh lime zest.
Key Lime Cheesecake Bars
For a convenient and shareable twist, try making key lime cheesecake bars. Using the same filling and crust, press the mixture into a baking dish instead of a springform pan. Bake until set, then chill and cut into squares for perfect portions. These bars are ideal for potlucks and gatherings—they’re easy to transport, and everyone loves a good slice of cheesecake!
Cooking Tips and Notes for Key Lime Cheesecake
Avoiding Cracks in Your Cheesecake
To ensure your key lime cheesecake bakes evenly and remains crack-free, avoid overmixing your batter once the eggs are added. Overmixing can introduce excess air, leading to cracking during cooling. Additionally, consider using a water bath, as steam helps maintain moisture and even temperature.
Ingredient Temperature Matters
Always remember to bring your ingredients to room temperature before mixing. Softened PHILADELPHIA cream cheese blends more smoothly with other components, resulting in a creamy texture. You can speed up the process by setting your cream cheese and eggs out on the counter about 30 minutes before you start your recipe. For more expert tips, check out King Arthur Baking's guide.

Topping Ideas
Elevate your key lime cheesecake experience with some fun and delicious toppings!

For those wanting a citrusy kick, consider adding key lime or regular lime slices for an eye-catching presentation that's reminiscent of a tropical getaway.
Pairing with Fresh Fruits
Enhancing your key lime cheesecake with fresh fruits not only looks appealing but also balances the sweetness. Consider serving it alongside sliced kiwi, pineapple, or even mango. Their natural brightness and acidity contrast beautifully with the richness of the cheesecake, making every bite refreshing.
