This zesty key lime cheesecake perfectly balances smooth creaminess with bright citrus kick for your sweet table. The sharp lime cuts nicely through the deep cream cheese flavor, making a cool yet decadent dessert that always wows your friends.
I whipped up this cheesecake when my sister came back from her Florida Keys vacation. The bright citrus taste took her right back to her holiday memories, and we've made it for every family party since then.
Ingredients
- Graham cracker crumbs: Give that needed crunch base with their natural sweetness. You can buy boxes of ready-made crumbs or crush your own crackers in a blender.
- Granulated sugar: Cuts the sourness of the lime. Try to use real cane sugar for top results.
- Unsalted butter: Holds the crust together and adds flavor. Pick unsalted so you can manage how much salt goes in your dessert.
- Cream cheese: Creates the main body of our cheesecake. Any full-fat brand works great but let it sit out to warm up first.
- Key lime juice: Gives that special tangy taste. Fresh juice works best but bottled is fine too - just make sure it's real key lime, not a mix.
- Key lime zest: Boosts the citrus flavor. Get a small grater for the finest bits without bitter peel.
- Sour cream: Makes it moist with a mild tang that works well with lime. Full-fat gives the best feel.
- Eggs: Help it set and add richness. Let them warm up before mixing for smoother batter.
- Vanilla extract: Balances all flavors with sweet notes. Real extract tastes much better than fake.
- Heavy whipping cream: Makes a fluffy topping. Look for cream with high fat (36%+) for the best whip.
Step-by-Step Instructions
- Get the Crust Ready:
- Mix your graham crumbs with sugar in a bowl and stir in melted butter. Keep mixing till it looks like damp sand that sticks when you squeeze it. Dump it into a 9inch springform pan and pack it down hard with a measuring cup to make a flat, tight layer. The harder you push, the better your crust will stay together when you cut slices.
- Mix Up the Filling:
- Whip soft cream cheese in a big bowl with your mixer on medium until it's totally smooth, about 2 minutes. Slowly add sugar while keeping the mixer going until everything gets light and fluffy. Drop in eggs one by one, mixing just enough to blend each time. Don't mix too much after eggs go in or you'll get cracks later. Pour in your lime juice and vanilla, then gently fold in zest with a rubber spoon using soft movements.
- Cook It Right:
- Pour your creamy mix over the crust and smooth the top with a flat knife. Put the pan on a baking sheet to catch drips, then stick it in your oven at 325°F. Bake for 45-50 minutes until the sides are firm but the middle still wiggles a bit when you shake it gently. The cake will keep cooking as it cools and will get firmer. Don't open the oven while it's baking or you might get cracks.
- Make Your Whipped Topping:
- Stick your bowl and beaters in the freezer for 15 minutes first - this helps get more volume. Pour cold cream into the cold bowl and beat at medium speed until it starts getting thick. Slowly add powdered sugar and vanilla while turning up to high speed. Keep beating until you see stiff peaks when you lift the beater - the cream should stand up straight without falling over. Don't beat too long or you'll end up with butter.
- Cool and Enjoy:
- Switch off the oven and leave the door cracked open so the cake can cool slowly for an hour - this stops cracks from forming. Take it out and slide a knife around the edge to free the cake from the pan. Let it cool all the way at room temp, then cover and put in the fridge for at least 4 hours, but overnight is better. The taste gets even better with time. When ready to serve, take off the springform sides and move to a plate. Add whipped cream on top and some lime zest and slices to make it look pretty.

Those tiny key limes really make this cheesecake stand out. They're smaller and more fragrant than normal Persian limes with a unique taste that's stronger and a touch sweeter. My grandma showed me how to roll the limes firmly under my hand before squeezing to get every drop of that amazing juice.
Avoiding Cracks
Many folks say you need water baths for cheesecakes but I've found this recipe works great without one. The trick is to mix gently after adding eggs, avoid quick temperature shifts, and cool down slowly. If you do get cracks, don't stress about it. They won't change the taste and you can hide them with whipped cream anyway.
Make It Ahead
This cheesecake actually gets better over time as the flavors blend together. You can make it up to three days before you need it, just keep it covered in the fridge. The bottom stays crunchy and the filling stays smooth and creamy. Just put the whipped cream on top right before serving so it looks and feels fresh.
Ingredient Swaps
Can't find key limes? Regular limes work fine too, though you might want to use a bit less juice since they can be more sour. Bottled key lime juice works in a pinch when you can't get fresh ones. For something different, try Meyer lemons for a sweeter citrus flavor. You can also switch graham crackers for gingersnaps or vanilla wafers in the crust for a different taste.

Frequently Asked Questions
- → Can I use regular limes instead of key limes?
Sure thing, regular limes work fine, but they'll give a slightly different taste. Key limes pack more punch and smell stronger. When using regular limes, you might want to use a bit less since they're often more sour.
- → How do I prevent my cheesecake from cracking?
Don't mix the batter too much as this adds unwanted air. Try baking it in a water bath by covering your pan with foil and setting it in a bigger pan with hot water. And watch your baking time. The middle should wobble a little when you take it out.
- → Can this cheesecake be frozen?
You bet it can. Let it cool all the way, then wrap it tight with plastic and foil. It'll keep in the freezer for up to 2 months. When you want it, let it thaw in the fridge overnight and add fresh toppings before you dig in.
- → How long should I let the cheesecake cool before refrigerating?
Let your cake sit out for about an hour. Then pop it in the fridge for at least 4 hours or better yet, leave it overnight. This slow cooling stops cracks and makes the flavors really come together.
- → What's the best way to cut clean slices of cheesecake?
Grab a sharp knife and dunk it in hot water. Wipe it dry, then make one cut. Do this again for each new slice. The warm knife slides through the cake without making a mess or dragging stuff along.
- → Can I make this without a springform pan?
A springform pan works best, but you can try a deep pie dish or cake pan with parchment paper hanging over the sides to pull the cake out after it cools. It won't look as nice, but it'll taste just as good.
