Key Lime Cheesecake

If you haven’t noticed yet I could live on cheesecake! Now if only I could figure out how to make it healthy. I actually love a good splurge once in a while – as in every weekend I need a really decadent dessert like so. I say “need” because I basically do feel like I need it, it gives me a good start to a new week. Makes me feel nice and refreshed :).

It’s like a spa treatment through my eyes. I’d take something like this over a back massage any day!

You know it’s good when you can’t help but reach into the fridge at midnight for another slice (whoops)! Trust me though it is worth every single calorie. We all need to treat ourselves sometimes and this is the perfect bright, summery cheesecake to make for any kind of celebration this summer… or to make just because.

I wouldn’t wait for a celebration or get-together to make this if you don’t have one coming up soon. You’ll have to make it just because life needs cheesecake sometimes.Key Lime Cheesecake | Cooking Classy

So yes, this is called Key Lime Pie, but to be honest, I’ve never baked with Key Limes. I don’t have the patience to juice millions of itty bitty limes to get 1/2 cup of juice. I mean, really, though, what do you get out of one of those things, a teaspoon of juice? Some people swear by that key lime flavor, though!

Fresh lime juice is a must here though, whether you choose to use Persian Limes (the regular size) or key limes it won’t make a huge difference. Either way, you’ll end with one incredible cheesecake that is basically guaranteed to get rave reviews (just please don’t use bottled lime juice, it won’t be nearly as good)!

Another important step is the water bath. The extra effort with hot water surrounding your pan will prevent cracks as the cheesecake returns to room temperature after baking. Follow the instructions carefully, including using a paddle attachment for your electric mixer or the bowl of a stand mixer to mix your batter completely, preventing bubbles and chunks that can ruin our cheesecake batters. Don’t forget to scrape up the bottom of the bowl!

Top with fruit and dollops of whipped cream and VOILA! My family loved it, and since we are a small family I got to eat it for three days straight – it was a good three days! (Thanks to plastic wrap!) Make this cheesecake at least once this summer, the summer won’t be complete until you do!

Key Lime Cheesecake

This Key Lime Cheesecake is unbelievably delicious! It's perfectly tart, perfectly sweet, perfectly tangy, perfectly creamy, perfectly luscious - it's perfectly everything! You know it's good when you can't help but reach into the fridge at midnight for another slices (whoops)! Trust me though it is worth every single calorie.
Servings: 14
Prep30 minutes
Cook1 hour 15 minutes
Chilling9 hours
Ready in: 10 hours 45 minutes

Ingredients

Crust

  • 2 cups (230g) crushed graham cracker crumbs (from 15 full sheets)
  • 3 Tbsp (39g) granulated sugar
  • 1/2 cup (113g) salted butter, diced into 1 Tbsp pieces and melted

Filling

Toppings

  • 1 cup (235ml) heavy cream
  • 2 1/2 Tbsp (33g) granulated sugar
  • Fresh raspberries or sliced strawberries, lime wedges, lime zest and fresh mint (optional)

Instructions

  • For the crust: Preheat oven to 350 degrees. Line the outside of a 9-inch springform pan with a sheet of 18 by 18 heavy duty aluminum foil*. 
  • Add graham crackers and sugar to a mixing bowl and stir to combine, then pour in butter and mix with a fork until evenly moistened. 
  • Pour into prepared springform pan and press evenly into bottom and up the sides coming about 1-inch from the top. Bake in preheated oven 10 minutes, then remove and cool on a wire rack.
  • Reduce oven temperature to 325 degrees. Have a large roasting pan ready and boil about 4 quarts of water (you may not need all of it).
  • For the cheesecake filling: In a small mixing bowl whisk together granulated sugar and cornstarch until well combined. Add cream cheese to a large mixing bowl, pour sugar mixture over top and using an electric hand mixer blend cream cheese until smooth.
  • Mix in eggs one at a time, mixing just until combined after each addition. Scrape down sides and bottom of bowl. Add sour cream and heavy cream and mix until combined. 
  • Mix in lime juice and vanilla. Tap bowl forcefully against countertop about 30 times to release any large air bubbles. 
  • Pour over cooled graham cracker crust. Place cheesecake in roasting pan then place roasting pan in oven and carefully pour in enough boiling water around cheesecake pan to reach halfway up the side of the cheesecake pan. 
  • Bake in preheated oven until cheesecake is nearly set but still jiggly in the center, about 60 - 65 minutes. Remove from oven and cool on a wire rack for 1 hour. Cover and chill in refrigerator 8 hours or overnight.
  • For the topping: In a medium mixing bowl whip heavy cream using an electric hand mixer set on high speed until soft peaks form. Add granulated sugar and whip until stiff peaks form. 
  • Transfer to a piping bag fitted with a star tip and pipe over cheesecake just before serving. Garnish with berries, lime wedges, lime zest and mint if desired. Store cheesecake in refrigerator.

Notes

  • *Make sure the foil has no holes, you don't want any water to leak in.

    Cheesecakes are my favorite cake to make Must say this one is THE BEST When I want a special cake this is the go to one. Enjoy your site Thanks for all

  • Jeffrey Wixon

    Turned-out Awesome. I did make some slight adjustments though:
    1. I used 1 cup finely crushed graham crackers and 1 cup pretzel sticks: layer out over wax paper and whacked-the crap out of them to crush; then filtered through a rough strainer into a bowl until I had enough for 2 cups (threw the rest in the garbage once I had enough… you can also use a rolling pin, as I did, with the stuff that “doesn’t” sift through the strainer)
    2. Used 9T of butter, not 8… melted the butter in the microwave for 1min
    3. Didn’t bother with the hot water bath but did do the foil part along the edges. 75 min exact.
    4. Used 8oz of Mascarpone cheese in place of one of the 8oz of Philly cream cheese
    5. Added grated zest of 4 limes and added a bunch of green food coloring.
    6. Didn’t bother “building-up the side walls with crumbs” but rather sprayed Pam spray generously around the inside perimeter between chilling after blind-baking the crust and adding the filling prior to baking.
    7. Rapped on the hardwood floor (I didn’t want to damage my countertop!) 50x, not 30x to remove air bubbles.

    I make this all the time and use biscoff as the base with less butter. Absolutely amazing. Always get the best compliments. Thank you Jaclyn!

  • Ed

    Can you place the spring form pan on a cooling rack inside the water bath to get it above the water level, but still inside the walls of the water bath pan?

      It wouldn’t cook quite as evenly this way but it would be better than no water in the oven.

  • Hannah

    I made this in Culinary school and have saved this recipe ever since. The lime isn’t to sour. Has a sweet taste. I love itttt.

      If it is a 1:1 substitute otherwise I’d follow the guide on the back of the bag for substitution amount.

  • Christy Lane

    Instead of placing the springform pan directly in the water in the pan, simply place the water filled pan on the rack below where the cheesecake is going to bake. If you do it this way, you do not need to worry about wrapping the springform pan in foil and you don’t have to worry about water leaking into your pan.
