- 3 large eggs
- 1/2 cup key lime juice
- 1 tablespoon finely grated lime zest
- 1 teaspoon vanilla extract

How to Make Key Lime Cheesecake
Step 1: Prepare the Pan
Preheat your oven to 325°F (165°C).
Lightly grease a 9-inch springform pan.
For easier removal, place a circle of parchment paper on the bottom of the pan.
If you plan to use a water bath, wrap the outside of the springform pan tightly with two layers of heavy-duty aluminum foil.
Step 2: Make the Graham Cracker Crust
Add the graham cracker crumbs and sugar to a bowl.
Pour in the melted butter and stir until all the crumbs are evenly coated.
Press the mixture firmly into the bottom of the springform pan and slightly up the sides.
Use the bottom of a measuring cup to press the crust into an even layer.
Bake for 8 to 10 minutes.
Remove the crust from the oven and allow it to cool while you prepare the filling.
Step 3: Beat the Cream Cheese
Place the softened cream cheese in a large mixing bowl.
Beat on medium-low speed until completely smooth.
Add the sugar and mix again until combined.
Avoid beating too much air into the cheesecake because excess air can contribute to cracks during baking.
Step 4: Add the Sour Cream and Lime
Add the sour cream, key lime juice, lime zest, vanilla, and cornstarch if using.
Mix on low speed until smooth.
At this stage, the filling should smell bright and citrusy while still looking thick and creamy.
Step 5: Add the Eggs
Add the eggs one at a time.
Mix on low speed just until each egg disappears into the filling.
Do not overmix after adding the eggs.
This helps the finished cheesecake bake more evenly.
Step 6: Fill the Crust
Pour the cheesecake filling over the cooled graham cracker crust.
Smooth the surface with a spatula.
Gently tap the pan once or twice on the counter to release large air bubbles.
Step 7: Bake the Cheesecake
Bake for approximately 55 to 70 minutes.
The outer edges should look set, while the center should still have a gentle wobble when the pan is moved.
Do not wait until the center is completely firm.
It will continue to set as it cools.
Step 8: Cool Slowly
Turn off the oven.
Crack the oven door open and leave the cheesecake inside for about 45 minutes.
Slow cooling helps reduce sudden temperature changes that can cause cracks.
Remove the cheesecake and let it cool completely at room temperature.
Step 9: Chill the Cheesecake
Cover the cheesecake and refrigerate for at least 6 hours.
Overnight is best.
A properly chilled cheesecake will be firmer, creamier, and easier to slice.
Step 10: Decorate and Serve
Beat the heavy whipping cream and powdered sugar until stiff peaks form.
Pipe or spoon the whipped cream around the top of the cheesecake.
Finish with:
- Fresh lime zest
- Thin lime slices
- Graham cracker crumbs
Slice and serve cold.
Why Key Lime and Cheesecake Work So Well Together
Cheesecake is naturally rich, sweet, and creamy.
Key lime brings acidity and freshness, helping balance that richness.
That is what makes key lime cheesecake feel both indulgent and refreshing at the same time.
The buttery graham cracker crust also connects the dessert to classic key lime pie.
Easy Lime Cheesecake With Graham Cracker Crust
You do not have to use actual key limes to make a delicious lime cheesecake.
Regular Persian limes work well too.
They are larger, easier to juice, and available in most grocery stores.
For the best flavor, use both:
- Fresh lime juice
- Fresh lime zest
The zest contains fragrant oils that add more citrus aroma without adding extra liquid to the cheesecake.
Key Lime Pie Cheesecake
This dessert is essentially a key lime pie cheesecake because it combines the best parts of both desserts.
From key lime pie, you get:
- Tangy lime flavor
- Graham cracker crust
- Fresh citrus aroma
- Whipped cream topping
From cheesecake, you get:
- Cream cheese richness
- Dense but creamy texture
- A tall, impressive presentation
It is a great dessert for anyone who has trouble choosing between pie and cheesecake.
How to Prevent Cheesecake Cracks
A cracked cheesecake still tastes delicious, but a few simple steps can help keep the top smoother.
Use room-temperature ingredients
Cold cream cheese is more difficult to blend smoothly.
Don’t overmix
Especially after adding the eggs.
Bake gently
A lower oven temperature helps the cheesecake cook more evenly.
Avoid overbaking
The center should still wobble slightly when you turn off the oven.
Cool slowly
Letting the cheesecake cool gradually reduces sudden temperature changes.
And if you do get a crack, whipped cream covers it beautifully.
Do I Need a Water Bath?
A water bath can help cheesecake bake evenly and stay creamy, but it is not absolutely required.
If using one:
- Wrap the outside of your springform pan tightly in foil.
- Place the cheesecake pan inside a larger roasting pan.
- Pour hot water into the larger pan until it reaches about halfway up the cheesecake pan.
- Bake as directed.
If you prefer to skip it, bake the cheesecake normally and focus on avoiding overbaking.
Can I Use Regular Limes Instead of Key Limes?
Yes.
Regular limes make an excellent substitute.
Use the same amount of juice listed in the recipe.
The flavor will be slightly different, but you will still get a refreshing citrus cheesecake.
Can I Use Bottled Key Lime Juice?
Yes.
Bottled key lime juice is convenient and works well when fresh key limes are difficult to find.
Fresh juice generally gives the brightest flavor, especially when combined with fresh zest.
Key Lime Cheesecake Bars
You can easily turn this recipe into key lime cheesecake bars.
Bars are excellent for:
- Parties
- Picnics
- Potlucks
- Showers
- Dessert tables
- Make-ahead entertaining
How to Make the Bar Version
Use a parchment-lined 9×13-inch pan.
Prepare the graham cracker crust and press it firmly into the pan.
For a thinner cheesecake layer, you can use the same filling and adjust baking time.
Bake until the edges are set and the center has only a slight jiggle.
Start checking around 30 to 40 minutes, depending on the thickness of the filling.
Cool completely, then refrigerate for several hours before slicing.
Top each bar with a small swirl of whipped cream and lime zest.
Mango Key Lime Cheesecake
For a tropical variation, make a mango key lime cheesecake.
Sweet mango works beautifully with tart lime and creamy cheesecake.
You can add mango in several ways.
Mango Swirl
Blend ripe mango until smooth.
Drop small spoonfuls over the cheesecake filling and gently swirl them with a knife before baking.
Mango Topping
After the cheesecake has chilled, spread a thin layer of mango puree over the top.
Fresh Mango Garnish
Decorate individual slices with small cubes or thin slices of ripe mango.
For the best balance, keep the mango layer fairly light so the key lime flavor still comes through.
How to Make the Cheesecake Extra Creamy
For the smoothest filling:
- Use full-fat cream cheese.
- Bring the cream cheese to room temperature.
- Use sour cream for extra softness.
- Mix on low speed.
- Avoid overbaking.
- Chill overnight before serving.
The texture improves significantly after a long chill.
How Long Does Key Lime Cheesecake Need to Chill?
Give the cheesecake at least 6 hours.
Overnight is ideal.
Cheesecake needs this time to firm completely and develop its best texture.
If you try slicing it too early, the center may feel overly soft.
How to Store Key Lime Cheesecake
Keep the cheesecake covered in the refrigerator.
For the best quality, enjoy it within approximately 4 days.
Return leftovers to the refrigerator soon after serving.
Can You Freeze Key Lime Cheesecake?
Yes.
Cheesecake freezes very well.
For best results:
- Chill the cheesecake completely.
- Slice it into individual portions if desired.
- Wrap each slice tightly.
- Place the slices in an airtight freezer-safe container.
Freeze for up to about 1 month for best quality.
Thaw overnight in the refrigerator.
Add fresh whipped cream and lime garnish after thawing.
Key Lime Cheesecake Topping Ideas
Try topping your cheesecake with:
- Whipped cream
- Lime zest
- Thin lime slices
- Graham cracker crumbs
- Mango slices
- Toasted coconut
- White chocolate curls
- Fresh berries
For Pinterest photos, whipped cream around the outside with small lime slices creates a clean and recognizable key lime look.
