    My Key Lime Cheesecake features a smooth and creamy key lime custard filling over a crisp graham cracker crust. This recipe is easy, with NO water bath and minimal prep time. Recipe includes a how-to video!

    A Slice of Paradise

    This highly-requested key lime cheesecake recipe eluded me for years. Three years, to be exact. While you might think that it would be as simple as adding a splash of lime juice and zest to my classic cheesecake recipe, it turns out that is absolutely not the case.

    Simply adding lime juice actually negatively affected the texture; made it too mealy, too airy for what should be a smooth and creamy custard, and resulted in a lackluster lime flavor that was lost beside the tang of the cream cheese. I went through dozens of boxes of said cream cheese before repeatedly, begrudgingly, tabling the recipe to perfect at a later time.

    The key lime cheesecake breakthrough finally came when I cracked the code for my lemon cheesecake recipe. Rather than simply adding juice (which contains a great deal of water and results in the awkward texture), cooking the juice into a curd results in a smooth, creamy custard. Equally importantly, it also yields bright key lime flavor that’s not too sour with just the right amount of tart–like a key lime pie and cheesecake rolled into one!

    Cut yourself a slice, and you’ll be grateful this recipe only took three years of testing! 😉

    What You Need

    You need just 9 ingredients to make this this cheesecake! Here are a few of the important ones:

    • Key lime juice. If you have access to key limes–great! Otherwise, bottled key lime juice is fine. When I can’t find fresh limes I use the brand pictured above (Nellie & Joe), which is evidently not a true key lime (it’s a “key west lime”, tricky!) but does in fact yield the proper key lime flavor and is preferable to regular lime juice (which I don’t recommend).
    • Room temperature cream cheese. Full-fat, brick-style cream cheese is the only kind I recommend using in any of my cheesecake recipes.
    • Sour cream. This works nicely with the key lime flavor, deepening it and imparting just the right amount of tartness to the key lime cheesecake.
    • Graham crackers. Digestive biscuits will also work if you don’t have graham crackers in your area. Gingersnaps would be delicious too!

    SAM’S TIP: Your key lime curd will need to cool completely before you add it to the cheesecake batter. To speed this up, you can place the curd in the fridge (just remember to place a piece of plastic wrap against the surface first!)

    Remember, this is just an overview of the ingredients I used and why. For the full recipe please scroll down to the bottom of the post!

    How to Make Key Lime Cheesecake

    1. Whisk together the curd ingredients in a small saucepan over medium heat-low heat until thickened. The thickening will happen quickly and be quite subtle, it won’t thicken quite as obviously as, say, pastry cream but you’ll notice the whisk will leave subtle trails and the mixture will likely begin to bubble.
    2. Pour the curd through a fine-mesh strainer and let it cool completely.

    1. Combine the graham cracker crumbs and sugars, then stir in the melted butter.
    2. Press this mixture into a springform pan, going as far up the sides as you can. You want the crust to be higher than the key lime cheesecake batter will be once added, this is key to preventing cracks!

    1. Cream together the cream cheese and sugar until smooth, then stir in the sour cream.
    2. Drizzle in the key lime curd with your mixer on low-speed.
    3. Add the eggs one at a time, then stir once more to make sure everything is incorporated.
    4. Pour the batter into your prepared pan and bake for 50-60 minutes. Let the cheesecake chill completely before slicing and serving.

    SAM’S TIP: Be gentle with your eggs! I’ve found that overbeating cheesecake batter, particularly once the eggs are added, can cause the cheesecake to crack.

    Frequently Asked Questions

    Do I need to use a water bath?

    No! Like all of my other cheesecake recipes, this recipe produces a smooth, crack-free cheesecake without a water bath.

    To avoid cracks, make sure to press your graham cracker crust as high up the sides of the pan as you can. Doing this will allow the crust to contract with the cheesecake as it cools, this preventing cracks during the cooling process. Overbeating the batter (particularly the eggs), using cold ingredients, opening the oven too much, and cooling too quickly can cause the cheesecake to crack too, so be mindful of these.

    Can you substitute lime for key lime?

    No. Key limes are less acidic and more floral than regular limes, so the flavor would be off. If you can’t find key limes in your grocery store, look for bottled key lime juice or key west lime juice in the juice aisle. You can use a regular lime zest for a garnish though, since it’s such a small amount.

    What is the difference between key lime pie and key lime cheesecake?

    Key lime pie has a more tart, more sweet, and less creamy flavor and texture. Key lime cheesecake has the flavor of key lime pie but also a strong cheesecake flavor, a thicker texture, and is taller.

    Is key lime pie supposed to be green?

    Key lime pie (and in turn, key lime cheesecake) should not be green. It should have a yellowish hue with maybe a slight hint of green, but not overtly so. Key lime pies that are green usually have food dye added to them.

    Ingredients

    For Key Lime Curd

    • ½ cup (118 ml) key lime juice
    • 3 large egg yolks
    • ¼ cup (50 g) granulated sugar
    • ¼ teaspoon table salt
    • 2 Tablespoons unsalted butter cut into 4 pieces

    Crust

    • 1 ½ cups (170 g) graham cracker crumbs
    • 2 Tablespoons granulated sugar
    • 1 Tablespoon light brown sugar firmly packed
    • 5 Tablespoons (71 g) unsalted butter melted

    For Cheesecake

    • 24 oz (680 g) cream cheese softened to room temperature
    • 1 cup (200 g) granulated sugar
    • ¼ cup sour cream
    • 2 large eggs lightly beaten, room temperature preferred

    Recommended Equipment

    • Saucepan
    • Fine Mesh Strainer
    • Mixing bowls
    • Electric mixer
    • 9" Springform pan

    Instructions

    For Curd

    • Combine key lime juice, egg yolks, sugar, and salt in a saucepan and whisk to combine. Add butter and turn stovetop to medium-low heat.
      ½ cup (118 ml) key lime juice, 3 large egg yolks, ¼ cup (50 g) granulated sugar, ¼ teaspoon table salt, 2 Tablespoons unsalted butter
    • Cook, whisking constantly, until mixture is slightly thickened (it will become more opaque and will likely begin to simmer just below the surface). Once this happens, immediately remove from heat and pour through a fine mesh strainer into a heatproof bowl.
    • Allow curd to cool completely before using in cheesecake batter, you may speed up the process by placing a piece of wax or parchment paper against the surface and refrigerating until cooled (about 30 minutes). While cooling, prepare crust and preheat oven to 325F (165C).

    Crust

    • Stir together graham cracker crumbs and sugars. Add butter and stir until well-combined and all crumbs are moistened.
      1 ½ cups (170 g) graham cracker crumbs, 2 Tablespoons granulated sugar, 1 Tablespoon light brown sugar, 5 Tablespoons (71 g) unsalted butter
    • Press crumbs into the bottom and up the sides of an ungreased 9” springform pan. Set aside. Once curd has cooled, prepare cheesecake batter.

    Cheesecake

    • In a large bowl using an electric mixer (or using stand mixer with paddle attachment), stir together cream cheese and granulated sugar on medium-low speed until creamy, smooth, and completely combined.
      24 oz (680 g) cream cheese, 1 cup (200 g) granulated sugar
    • Add sour cream and stir until combined. Scrape sides and bottom of bowl with a spatula.
      ¼ cup sour cream
    • With mixer on low-speed stir in cooled key lime curd until completely combined.
    • Add eggs one at a time, stirring on low speed until just combined after each addition. Scrape the sides and bottom of the bowl as needed to ensure batter is uniform.
      2 large eggs
    • Pour batter evenly into prepared cheesecake pan and bake in the center rack of your oven on 325F (165C) for 50-60 minutes. The cheesecake should be mostly set once finished but the center will still jiggle slightly like jello once it is finished baking.
    • Allow cheesecake to cool to room temperature for about an hour then, once it’s cool enough to pick up, transfer to refrigerator to chill 6 hours or overnight before slicing and serving (I leave the cheesecake in the springform pan until serving).
    • Serve topped with a generous dollop of homemade whipped cream.

    Notes

    Storing

    Store in the refrigerator for up to 5 day. I store directly in the springform pan covered with foil or plastic wrap.

      Hi Sam, I’ve made your receipes before and they’ve always been fantastic so I totally trust in your receipes. I’m going to make this cheesecake and want to know if I increase the fresh lime juice from 1/2C to 3/4C for the curd will that change the texture/consistency or throw off the balance? I recently made a key lime pie that called for 3/4C fresh lime juice, 28-oz sweetened condensed milk and 1C plain greek yogurt; I loved the taste which was very limey and tangy, just the way I liked it. So please advise your thoughts on the lime juice increase as I want this to come out perfect for Mother’s Day. TY!

        Hi Sharon! I wouldn’t recommend increasing the liquid here. It could cause issues with the cheesecake setting.

        Hi Jeanie! That should be fine, I would probably pull your curd out of the refrigerator about 15 minutes before using it so it’s not too cold.

      This is the best cheesecake I have ever eaten and the recipe is perfect. I like walnuts so I added a little bit of crushed walnuts to the crust but recipe is perfect as is. There is just the right amount of lime flavor and creaminess. The instructions are easy to follow. I have now made it four times and it takes wonderful with homemade whipped cream on top as shown in the photos. Thank you so much for sharing this recipe!! If I could give it more than 5 stars I would! ๐Ÿ˜‰

      I made the cheesecake and it was delicious!! I want to try your key lime cheesecake next. Looking over the recipe I noticed the reg. cheesecake crust calls for 7 Tbls. butter but the key lime calls for 5 Tbls. Why is that?

        Hi Leigh! The key lime cheesecake is a wetter batter so the reduced sugar helps keep the proper consistency. ๐Ÿ™‚

      Iโ€™ve made this twice now and it got rave reviews both times. I served it with two easy sauces, mango and raspberry. Iโ€™ve tried all your cheesecake recipes now, and theyโ€™ve all been winners! I especially like that yours do not require a water bath โ€“ who wants to fool around with that!? Have not tried the stuffed cheesecake recipes, so will try those next!

          I made this for the first time today for a customer. I make a great New York cheesecake but he requested a key lime one. The recipe wasnโ€™t hard. But I didnโ€™t get he crust high enough. It looks like it over ran a little. It did jiggle just like hello when I pulled them out of the oven. Canโ€™t wait and see if itโ€™s a hit tomorrow.
