Key Lime Cheesecake Recipe

Key lime is the quintessential summer dessert flavor. I have quite a few key lime desserts already on the blog (no-bake key lime cheesecake and key lime cake are great!) but I thought that a classic cheesecake recipe needed to be added to the list. Key lime cheesecake is creamy, sweet, just a little bit tart, and everything that a summer dessert should be.

The light and fluffy cheesecake filling sits on top of a buttery graham cracker crust. It’s then finished off with a homemade whipped topping, lime zest for some extra citrus flavor, and key lime slices for a picture-perfect presentation! If you want to bring a show-stopping dessert to your next potluck, this key lime cheesecake is the way to go. With how creamy, flavorful, and indulgent it is, everyone will want a slice!

Ingredients for Key Lime Cheesecake

This is everything you will need to create a bakery-worthy key lime cheesecake. Trust me, you’ll think the grocery trip is worth it once you try a bite of this creamy, tangy heaven. Looking for measurements? They can all be found below in the recipe card.

Crust

• Graham Cracker Crumbs: Crushed graham crackers give the crust nutty flavor and delicious texture!
• Granulated Sugar: To add a touch of sweetness to the crust.
• Unsalted Butter: Adds a tasty richness to the crust. Butter also helps to hold everything together. Since we’re adding salt separately, I used unsalted butter here.
• Salt: You only need a pinch to make the crust even more delicious.

Cheesecake

• Cream Cheese: It’s best if your cream cheese is at room temperature. This way, it mixes together smoothly with the other filling ingredients. Also, full fat cream cheese is the way to go. It will make your cheesecake nice and rich.
• Granulated Sugar: To balance out the tartness of the key lime juice and zest.
• Sour Cream: I know it seems out of place, but sour cream helps to make the cheesecake so soft and dreamy!
• Key Lime Juice: Freshly squeezed is best. Save the rind for some zest!
• Large Eggs: Give the cheesecake structure.
• Vanilla Extract: Adds warm, sweet flavor to the mixture.
• Key Lime Zest: A great way to add an extra pop of key lime flavor.

Topping

• Heavy Whipping Cream: To whip up into light, fluffy goodness.
• Powdered Sugar: Helps to sweeten and stabilize the whipped topping.
• Key Lime Zest: Because you can’t go wrong with more lime flavor!
• Key Lime Slices: For that bakery-worthy finishing touch.

Let’s Get Cooking!

Making homemade key lime cheesecake isn’t as difficult as it seems. I know this is a lot to read, but I’ve included a lot of tips and tricks on how to get your cheesecake to turn out perfectly. Patience and attention to detail is key (or should I say, key lime) here!

Crust

• Preheat Oven, Prepare Pan: Preheat the oven to 325 degrees Fahrenheit. Prepare a 10-inch springform pan by spraying with cooking spray. To crush graham crackers, place in a sealed bag and use a rolling pin, or pulse in a food processor.
• Combine Crust Ingredients: In a medium bowl, mix the graham cracker crumbs, sugar, melted butter, and salt together. This should resemble damp sand.
• Press Into Pan: Pour the crumb mixture into the prepared springform pan and press evenly into the pan. You can use the bottom of a flat glass or a flat measuring cup to really press it in well and get a nice, even crust.
• Bake: Bake for 10 minutes. Allow to cool completely.

Cheesecake Filling

1. Beat Cream Cheese: Add the softened cream cheese to the mixing bowl of a stand mixer and beat with a paddle at medium/high speed for about 1 minute. Scrape down the sides and bottom of the bowl and beat for another minute or so, until very smooth.
2. Add Sugar and Sour Cream: Add the sugar and sour cream and mix at medium/low speed until just combined. Scrape the bowl again and mix again for 30 seconds.
3. Mix in Remaining Ingredients: Add the lime juice, eggs, vanilla, and key lime zest and beat on low speed until combined, about 30 seconds-1 minute. Scrape the bowl again. Beat until just combined. At this point the key lime cheesecake batter should be smooth and fairly runny.

Baking

1. Wrap Springform Pan: Using 18 inch heavy-duty aluminum foil, wrap the outside of your springform pan with 4 sheets of foil. You can use regular foil, but it may take a couple more sheets to ensure the water does not get into your pan.
2. Add to Roasting Pan: Place the wrapped pan in a large roasting pan with deep sides. You can alternatively use a baking sheet, so long as the sides are about 2 inches deep.
3. Prepare Water Bath: Using very hot water, add water to the baking sheet until there is about 1 ½ inch of water around the springform pan. With the rack in the lower 3rd of the oven, carefully move the pan into the oven.
4. Bake: Bake at 325 degrees Fahrenheit for 1-1 ½ hours. After about an hour of baking, check the cheesecake’s consistency. A slight jiggle of the pan (while still in the oven) should tell you if it’s ready or needs more time. The cheesecake should be only slightly jiggly, but not liquid. If it still seems very liquidy, give it 15 more minutes and check it again.
5. Cool in the Oven: Once the cheesecake has only a slight jiggle, turn the oven off but leave the cheesecake in the oven for another hour or so, until the oven has cooled down. Resist the temptation to open the oven during this time! The purpose of this step is to allow the cheesecake to cool slowly as the oven cools. Doing this will prevent it from cracking, as one of the biggest reasons cheesecakes crack is the drastic temperature change going from the hot oven into the much cooler kitchen.
6. Chill in the Fridge: Once the oven and the cheesecake are cooled, remove from the oven and carefully remove the foil lining the pan. Cover and chill in the fridge for at least 6 hours.
7. Add Topping: Before serving, whip together the cream, powdered sugar, and zest until medium soft peaks form. Either pipe or spread the whipped cream over the top of the key lime cheesecake and garnish with slices of fresh key limes.
