I’ve made a lot of cheesecakes over the years, but this one gets more compliments than any other flavor I make.
It’s rich and creamy like classic cheesecake, but with this sharp, zesty lime flavor running through every bite that keeps it from feeling heavy. A buttery graham cracker crust underneath, a swirl of whipped cream on top, and just enough lime zest to make it look as good as it tastes.
If you’ve only ever had key lime pie, this cheesecake version might just become your new favorite way to eat it. 🍋
Why This Recipe Works So Well
Key lime juice has a sharper, slightly more floral flavor than regular limes, which gives this cheesecake its signature tang without needing a ton of extra ingredients.
Baking the cheesecake low and slow keeps the texture silky instead of dry or cracked, which is usually where most homemade cheesecakes go wrong.
And that graham cracker crust underneath adds just enough crunch and sweetness to balance out the tart, creamy filling on top.
What You’ll Need

For the crust:
- 1 1/2 cups graham cracker crumbs
- 6 tablespoons melted butter
- 3 tablespoons sugar
For the filling:
- 24 oz cream cheese, softened
- 1 cup sugar
- 3 large eggs
- 1/2 cup key lime juice
- 1 tablespoon lime zest
- 1/3 cup sour cream
- 1 teaspoon vanilla extract
For the topping:
- Whipped cream
- Lime slices
- Extra lime zest
Twelve ingredients, most already sitting in your fridge or pantry.
Tools You’ll Need

- A 9-inch springform pan
- A mixing bowl
- An electric mixer
- A rubber spatula
- A zester or fine grater
- A baking sheet (to place under the springform pan)
- A piping bag (optional, for the whipped cream)
How to Make Key Lime Cheesecake
- Preheat your oven to 325°F.
- Mix the graham cracker crumbs, melted butter, and sugar together, then press firmly into the bottom of your springform pan.
- Bake the crust for 8 to 10 minutes, then set aside to cool slightly.
- Beat the softened cream cheese and sugar together until smooth and creamy.
- Add the eggs one at a time, mixing on low speed after each addition just until combined.
- Mix in the key lime juice, lime zest, sour cream, and vanilla extract until fully incorporated.
- Pour the filling over the crust and smooth the top with a spatula.
- Place the springform pan on a baking sheet and bake for 45 to 55 minutes, until the center is just slightly jiggly.
- Turn off the oven and let the cheesecake sit inside with the door cracked for 1 hour.
- Chill in the fridge for at least 4 hours, or overnight, before releasing the springform ring.
- Top with whipped cream, lime slices, and extra zest before serving.
Eleven steps, and most of the waiting happens while the oven and fridge do their thing.
Pro Tips From Many Cheesecakes Later
Use room temperature cream cheese and eggs. Cold ingredients don’t blend as smoothly and tend to leave lumps that no amount of mixing fully fixes.
Don’t overmix once the eggs go in. Overbeating adds too much air, which is a big reason cheesecakes crack as they bake and then cool.
Use real key lime juice if you can find it. Bottled key lime juice or fresh key limes give you that distinct tart flavor that regular limes don’t quite replicate.
Let the cheesecake cool gradually. The slow cool-down in the turned-off oven helps prevent the surface from cracking from a sudden temperature change.
Chill for the full time before slicing. Cutting into a cheesecake too early means a softer, less structured slice. The full chill time gives you those clean, bakery-style slices.
Substitutions and Variations
| Swap this | For this |
|---|---|
| Key lime juice | Regular lime juice (slightly less tart) |
| Graham crackers | Digestive biscuits or vanilla wafers |
| Sour cream | Plain Greek yogurt |
| Regular sugar | Reduce slightly for a less sweet filling |
| Whipped cream topping | A thin layer of meringue, torched lightly |
You can also swirl a bit of extra lime juice and sugar into the batter before baking for a marbled effect on top.
Make Ahead Tips
Cheesecake practically demands to be made ahead, since it needs several hours to chill regardless.
Bake and chill it up to 2 days in advance, keeping it covered in the fridge, then add the whipped cream and garnish right before serving.
A Few Extra Details Worth Knowing
Nutrition-wise, a single slice lands around 380 to 420 calories, depending on how generous the crust and whipped cream topping are.
For different diets:
- Gluten-free: use gluten-free graham crackers for the crust
- Lower sugar: reduce the sugar in both the crust and filling slightly
- Lighter version: use reduced-fat cream cheese and sour cream, though the texture will be a bit less rich
Pairing suggestions: this cheesecake pairs well with a cup of coffee or iced tea, especially after a lighter summer meal.
Time-saving tip: make the crust and bake the cheesecake the day before serving, so day-of prep is just adding whipped cream and lime garnish.
Leftovers and Storage
Store covered in the fridge for up to 5 days.
This cheesecake also freezes well. Wrap individual slices tightly in plastic wrap, then foil, and freeze for up to 2 months. Thaw overnight in the fridge before serving.
FAQ
Why did my cheesecake crack on top?
This usually happens from overmixing the batter, baking at too high a temperature, or cooling too quickly. The gradual cool-down step helps prevent this.
Can I use bottled key lime juice instead of fresh key limes?
Yes, bottled key lime juice works great and saves a lot of time, since fresh key limes are small and take a while to juice.
Why is my cheesecake still jiggly after baking?
A slight jiggle in the center is actually what you want. It firms up completely as it chills, so don’t bake it until it’s completely set in the oven.
Can I make this in a water bath instead?
Yes, a water bath can help prevent cracking even further if you want extra insurance, just wrap the outside of your springform pan tightly in foil first.
How do I get clean slices when cutting?
Dip your knife in hot water and wipe it clean between each slice for that smooth, bakery-style cut.
Wrapping Up
This cheesecake has a way of making people ask for the recipe before they’ve even finished their first bite.
