Key limes are smaller and have a more intense, floral flavor than regular limes. Fortunately, for this cheesecake, you can use either regular limes or key limes.
Cheesecakes require the use of a springform pan. This type of pan allows for even baking, easy release, and less mess. If you don’t have one, you should be able to pick one up at most stores in the aisle with other baking pans.
If you want to keep the cheesecake from cracking, turn the oven off, and let it cool with the door closed for a minimum of 1 hour and a maximum of 3 hours.
Yes! The water bath creates steam in the oven, keeping the cheesecake moist during baking. Cheesecakes can dry out from the heat of the oven and a water bath helps combat this. The water bath also allows the cheesecake to cook slower and more evenly, which prevents cracking.
Cheesecake should come out of the oven with a slightly jiggly center. It will take a few hours to cool and set properly, so don’t worry! If after baking, you press gently in the center of the cheesecake and runny batter comes off on your finger, it needs a bit longer to bake.

Make Ahead Instructions

Freezing Instructions
Freeze key lime cheesecake whole or cut into slices tightly wrapped in plastic wrap for up to 3 months.
Substitutions
- Graham cracker crumbs or golden Oreos can be used in place of vanilla wafers.
- Regular granulated sugar can be used instead of brown sugar.
- Plain or Greek yogurt can be used in place of the sour cream.
- All-purpose flour can be used instead of cornstarch; simply increase the amount used to 2 tablespoons.
- Regular (Persian) lime juice can be used in place of the key lime juice.
Tips for the Best Key Lime Cheesecake
- Use bricks of full-fat cream cheese, not cream cheese in a tub.
- Make sure all of the cheesecake batter ingredients are at room temperature so the batter remains smooth and combines quickly.
- When making the cheesecake, be sure to beat the cream cheese well at the beginning to ensure that it is smooth. If, when the cheesecake batter is complete, you still have lumps, simply press them against the side of the bowl using a wooden spoon or rubber spatula.
- Do not overmix the cheesecake batter as it will add air and result in uneven baking and can cause it to crack at the end.
- The center of the cheesecake should jiggle slightly when it is properly baked.
- Be sure to leave the cheesecake in the oven for the hour after baking to rest. This allows the cheesecake to set, thus preventing or at least lowering the chances that the cheesecake top cracks.
- Once the cheesecake is baked, placing it onto a cooling rack allows all of the cheesecake to be exposed to the air to cool more quickly. However, you can place the cheesecake onto a hot pad to cool, it may just take a little longer.
- This cheesecake freezes really well. For ease of serving, I like to slice the entire cheesecake into individual slices and then wrap each slice in plastic wrap really well. This makes for ease of freezing and for quick serving later on.
- If the heavy cream becomes flat and granulated after whipping it, it has broken and will continue disintegrating. If you have reached this point, start over and be sure to watch the heavy cream as it is whipping up.
A sweet, buttery wafer crust serves as the base to this tangy Key Lime Cheesecake. While you don’t necessarily have to top it off with the homemade cream cheese frosting, it’d be a real shame to skip it. The crust, filling, and frosting always make for such a perfect bite!

Instructions
For the Crust
- Preheat oven to 350°F. Line the bottom of a 9-inch springform pan with parchment paper and spray with baking spray. Set aside.
- In a medium-sized bowl, whisk the crushed vanilla wafers and brown sugar together. Add in the melted butter and stir until the mixture resembles wet sand. Press the crust into the bottom and slightly up the sides of the springform pan. Place the pan into the oven to bake for 15 minutes. Once baked, remove from the oven and place onto a cooling rack to cool slightly while you make the cheesecake batter. Increase the oven heat to 400°F.3½ cups crushed vanilla wafers, ⅓ cup brown sugar, 10 tablespoons salted butter
For the Cheesecake
- In the bowl of a stand mixer fitted with a paddle attachment, beat the cream cheese and sugar together on high speed for 2 minutes to ensure that the mixture is creamy and that no cream cheese lumps remain. Add in the heavy cream, sour cream, salt, and vanilla and mix for about 30 seconds to combine. Add in the lime juice and stir to incorporate. Add in the eggs and mix just until incorporated. Lastly, add in the cornstarch and mix until combined. Pour the cheesecake batter into the springform pan and smooth out.24 ounces cream cheese, ⅔ cup granulated sugar, ½ cup heavy cream, ⅓ cup sour cream, 1 teaspoon kosher salt, 1 teaspoon pure vanilla extract, ⅓ cup fresh key lime juice, 2 large eggs, 2 egg yolks, 1½ tablespoons cornstarch
- Wrap the bottom and up the sides of the springform pan with aluminum foil to prevent any water from seeping in. Place the springform pan into a large baking pan or broiler pan and fill the broiler pan with 1 inch of water to create a water bath.
- Place the pans into the preheated oven to bake for 15 minutes. Reduce the heat to 250°F. Bake for 1 hour and 10 minutes. Turn the heat off and leave the cheesecake in the oven with the door closed for 30 minutes. Crack the oven door and let the cheesecake set in the oven for another 30 minutes.
- Once the cheesecake has set, remove it from the oven, unwrap the aluminum foil, and place the springform pan onto a cooling rack to cool completely. Once cooled, cover with tinfoil and place into the fridge to chill for at least 8 hours.
For the Frosting
- To make the frosting for the top, place the cream cheese, powdered sugar, salt, and vanilla into the bowl of a stand mixer fitted with a whisk attachment. Whip together for 2 minutes. Transfer the cream cheese mixture to a different, medium-sized bowl. Add the heavy cream to the bowl of the stand mixer. Whip on medium-high speed for 2 minutes, or just until the whipped cream has formed stiff peaks. Use a rubber spatula to fold the cream cheese mixture into the whipped cream until smooth and fully combined. Spoon the mixture into a piping bag fitted with an open star piping tip.8 ounces cream cheese, ½ cup powdered sugar, ½ teaspoon kosher salt, ½ teaspoon pure vanilla extract, ⅔ cup heavy cream
- Once the cheesecake has chilled, run a butter knife around the inside edge of the springform pan to release the cheesecake. Release the springform and remove the sides from the cheesecake. Place the cheesecake onto a cake stand or serving platter. Pipe swirls of frosting around the edge of the cheesecake. Garnish with lime zest and lime slices if you so desire.
