I first made this cheesecake for a summer cookout, and it disappeared faster than the key lime pie sitting right next to it.
The filling stays smooth and dense instead of light and fluffy, which is exactly what a proper cheesecake should be.
If you already love my Key Lime Pie Bars, this cheesecake gives you that same bright citrus flavor in a taller, more dramatic dessert.

Ingredients
You only need a handful of ingredients for this cheesecake, split between the crust, the filling, and the topping.
Room temperature cream cheese, sour cream, and eggs are the key to a smooth, lump free batter.
- For the Crust: 2 cups graham cracker crumbs (about 16 full sheets), 1/3 cup granulated sugar, 1/4 teaspoon salt, 6 tablespoons unsalted butter, melted
- For the Filling: 32 ounces (4 blocks) cream cheese, softened, 1 cup granulated sugar, 1/3 cup sour cream, room temperature, 1 tablespoon key lime zest, 1/2 cup fresh key lime juice, 1 teaspoon vanilla extract, 1/4 teaspoon salt, 3 large eggs, room temperature
- For the Topping: 1 cup heavy whipping cream, cold, 2 tablespoons powdered sugar, 1/2 teaspoon vanilla extract, key lime slices for garnish, extra key lime zest for garnish

Kitchen Equipment Needed
Cheesecake is fairly forgiving once you have the right tools on hand.
Most of these are things you likely already own, aside from a proper springform pan.
- 9-inch springform pan
- Food processor (for the graham cracker crumbs)
- Stand mixer or hand mixer
- Large mixing bowls
- Rubber spatula
- Microplane zester
- Citrus juicer
- Heavy duty aluminum foil
- Offset spatula
- Wire cooling rack
I put together the exact same equipment list I use for my Pecan Pie Cheesecake Recipe, since both bake in a similar low and slow style.
Recommended Products for This Recipe
These are a few products I personally reach for whenever I make this cheesecake.
They are not required, but they genuinely make the process smoother and the results more consistent.
1. Nellie and Joe’s Key West Lime Juice
Fresh key limes can be hard to find outside of summer, and juicing them by hand takes forever since they are so small.
This bottled juice is the closest thing to fresh that I have found, with a clean tart flavor that does not taste processed.
2. OXO Good Grips Springform Pan
A sturdy springform pan with a tight seal is non negotiable for cheesecake, since a leaky pan means melted butter pooling in your oven.
This one releases the sides cleanly without dragging on the crust.
3. Microplane Premium Zester
The zest is where most of the actual lime flavor lives, and a sharp microplane grates it into fine, fluffy shreds instead of bitter chunks.
It also handles garnish zest beautifully for that finished bakery look.
4. Cheesecake Water Bath Baking Strips
Even with a crack resistant method, these insulated strips wrap around the pan and slow down heat on the sides, which helps the cheesecake bake more evenly.
It is a small investment that pays off every time you bake.
5. KitchenAid Stand Mixer
A stand mixer beats the cream cheese completely smooth without overworking the eggs, which is one of the biggest causes of cracked cheesecake.
It also frees up your hands to scrape the bowl as you go.
Step-by-Step Instructions: How to Make Key Lime Cheesecake
1. Prep Your Pan and Oven
- Preheat your oven to 325 degrees Fahrenheit.
- Grease the inside of a 9-inch springform pan with butter or nonstick spray.
- Wrap the outside of the pan tightly in two layers of heavy duty aluminum foil to protect against any leaks.
- Set the prepared pan aside while you make the crust.
2. Make the Graham Cracker Crust
- Pulse the graham crackers in a food processor until they turn into fine, even crumbs, or crush them in a zip top bag with a rolling pin.
- In a medium bowl, stir together the graham cracker crumbs, granulated sugar, and salt.
- Pour in the melted butter and mix with a fork until the crumbs look like wet sand and hold together when pressed.
- Press the mixture firmly into the bottom of the prepared springform pan and about 1 inch up the sides, using the bottom of a measuring cup to pack it tight.
3. Bake the Crust
- Place the crust in the preheated oven and bake for 10 minutes, until it looks set and lightly golden.
- Remove the crust from the oven and let it cool on the counter while you prepare the filling.
- Leave the oven on, since you will need it again shortly.
4. Beat the Cream Cheese
- In the bowl of a stand mixer fitted with the paddle attachment, beat the softened cream cheese on medium speed for 2 to 3 minutes, until completely smooth.
- Scrape down the sides and bottom of the bowl with a rubber spatula to make sure there are no lumps hiding underneath.
5. Add Sugar and Sour Cream
- Add the granulated sugar to the cream cheese and beat on medium speed until fully combined and smooth, about 1 minute.
- Add the sour cream and mix on low speed until incorporated, scraping the bowl again as needed.
6. Mix in the Key Lime Zest and Juice
- Add the key lime zest, key lime juice, vanilla extract, and salt to the bowl.
- Mix on low speed just until everything is evenly combined. Avoid overmixing at this stage.
7. Add the Eggs
- Add the eggs one at a time, mixing on low speed after each addition until just combined.
- Stop mixing as soon as the last egg disappears into the batter. Overbeating the eggs is the most common cause of a puffed up, cracked cheesecake.
8. Pour and Smooth the Filling
- Pour the cheesecake batter over the cooled crust in the springform pan.
- Use an offset spatula to smooth the top into an even layer.
- Tap the pan gently on the counter a few times to release any large air bubbles.
9. Bake the Cheesecake
- Place the pan on a baking sheet and bake at 325 degrees Fahrenheit for 50 to 60 minutes.
- The cheesecake is done when the edges look set and the center still has a slight jiggle, similar to gelatin.
- Avoid opening the oven door during baking, since temperature swings can cause cracking.
10. Cool Slowly to Prevent Cracks
- Turn off the oven and crack the door open a few inches, using a wooden spoon to prop it if needed.
- Let the cheesecake sit in the cooling oven for 1 hour. This slow cool down prevents the surface from cracking as it contracts.
- After 1 hour, remove the cheesecake from the oven and let it finish cooling on the counter to room temperature.
11. Chill the Cheesecake
- Once the cheesecake reaches room temperature, cover the pan loosely with plastic wrap.
- Refrigerate for at least 6 hours, though overnight is best for clean slices and fully set texture.
12. Make the Whipped Cream Topping
- In a chilled mixing bowl, add the cold heavy whipping cream, powdered sugar, and vanilla extract.
- Beat on medium high speed until stiff peaks form, about 2 to 3 minutes.
13. Garnish and Serve
- Run a thin knife around the edge of the pan before releasing the springform sides.
- Pipe or dollop the whipped cream around the edge or over the entire top of the cheesecake.
- Finish with thin key lime slices and a sprinkle of fresh key lime zest.
- Slice with a clean, warm knife between cuts for the neatest presentation.
The technique here is nearly identical to how I finish my Pumpkin Cheesecake Recipe, just swapping warm spice for bright citrus.
Tips for The Best Key Lime Cheesecake
A few small details make a big difference between a good cheesecake and a great one.
Most of it comes down to ingredient temperature and how gently you mix.
- Bring cream cheese, sour cream, and eggs to true room temperature before starting, about 1 hour on the counter.
- Use fresh key limes whenever possible for the brightest, most floral flavor.
- Mix on low speed once the eggs go in to avoid trapping excess air in the batter.
- Do not skip the slow cooldown in the oven, since it is the biggest factor in preventing cracks.
- Chill the cheesecake fully before slicing, since a warm cheesecake will not hold clean slices.
- Dip your knife in hot water and wipe it dry between each slice for bakery style cuts.

Serving Suggestions
This cheesecake is rich enough to serve on its own, but a few pairings really round out the plate.
Cold and bright drinks work especially well against the tangy filling.
- A slice alongside fresh berries and extra whipped cream
- Iced tea or a tall glass of Mint Lemonade for a warm weather pairing
- A light dusting of toasted coconut for extra texture
- Coffee or espresso to balance the sweetness
- A drizzle of extra key lime curd for lime lovers
Variations of Key Lime Cheesecake
Once you have the base recipe down, it is easy to shape this cheesecake around dietary needs or flavor twists.
Here are a few directions that work well without changing the overall method.
- No Bake Version: swap the baked filling for a whipped cream cheese and condensed milk mixture set in the fridge instead of the oven
- Mini Cheesecakes: divide the crust and filling into a muffin tin lined with cupcake liners for individual servings
- Chocolate Crust: use chocolate graham crackers or crushed chocolate cookies in place of regular graham crackers
- Coconut Key Lime: fold 1/2 cup of shredded coconut into the crust for a tropical twist
- Swirled Cheesecake: reserve a small portion of plain batter and swirl it through the key lime filling before baking for a marbled look

Storage and Reheating
Cheesecake actually improves after a day or two in the fridge, since the flavors have more time to settle.
It also freezes beautifully for longer storage.
- Refrigerator: store covered tightly in the pan or on a plate for up to 5 days
- Freezer: wrap individual slices in plastic wrap, then foil, and freeze for up to 2 months
- Thawing: move frozen slices to the fridge overnight before serving
- Serving Temperature: this cheesecake is meant to be served cold, so no reheating is needed
- Topping: add fresh whipped cream just before serving rather than storing it on the cheesecake
I use this same approach for storing my No Bake Mini Cheesecakes, since both hold up well in the freezer.

FAQs About Key Lime Cheesecake
1. Can I use regular limes instead of key limes?
Yes, regular limes work fine if key limes are not available.
The flavor will be slightly less floral and a bit more straightforward tart, but the texture and result will still be excellent.
2. Why did my cheesecake crack on top?
Cracking usually happens from overmixing the eggs, baking at too high a temperature, or cooling too quickly.
Following the slow cooldown step in the oven, the same method I rely on for my Red Velvet Cheesecake Recipe, solves this problem almost every time.
3. Do I need a water bath for this recipe?
No, this recipe is designed to bake without a water bath.
The low oven temperature combined with the slow cooldown period does the same job of preventing cracks and keeping the texture smooth.
4. Can I make this cheesecake ahead of time?
Absolutely, and it is actually recommended. Since it needs several hours to chill, making it a day ahead gives the flavors time to fully develop.
5. Why is my cheesecake filling lumpy?
Lumpy filling almost always comes from cold cream cheese or undermixing at the start.
Make sure your cream cheese is fully softened at room temperature and beat it thoroughly before adding any other ingredients.
