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.

    Okay, I am a military father and husband who never really has a lot of time to make food for my family, but yesterday I had some time off and I decided to make this Cheesecake and it turned out great my family loved it and we even had it for breakfast. I will make this again to show off my daddy skills in the kitchen when we start hosting family and friends. Loved it thanks.

  • MaryAnne Klinchock

    Made your pumpkin cheesecake for Thanksgiving. It was incredibly good! Just made your key lime cheesecake. Just wondering why the lime recipe called for a hand mixer and the pumpkin called for a food processor? Loved using the processor and mixing all the eggs at once. Thank you so much!!

    This cheesecake got rave reviews from co-workers when I made it for a birthday. One lady even said she thought it was the best cheesecake she’d ever eaten. That’s pretty high praise. Changes I made: I added one more package of cream cheese because I have a tall pan and I added lime zest (1 tsp) to the batter. Oh, and it took a lot longer to cook than 55 minutes. I baked it at 325 for two and a half hours in a water bath. Then I turned off the oven and opened the door and let it cool there. It was perfectly cooked but this is a wetter cheesecake than I usually bake. It turns into more of a key lime cheesecake dessert. So decadent and pretty. Thanks for the recipe. I’ve already been asked for it several times.

    Made it yesterday and followed your instructions exactly. Baked 65 minutes and it turned out nearly perfect. I got a small crack in the top (about an inch long). It was so delicious and I will make it again for sure.

  • Alicia

    I made this yesterday and brought it in for people I work with. Rave reviews!

    For some reason I have bad luck with water baths and my crusts (including this one) have ended up soggy. I also had an amber skin at the top of it so I ended up scraping it off and putting a thin layer of the whip cream on it to cover up the not-so-nice looking top portion before piping it onto the sides.

      You could try wrapping the outside of your springform pan in aluminum foil before putting it in the bath. Learned this on a baking show… :)

  • Roxanne

    I’ve made this at least 10 times. The family loves it. We just moved to Colorado from Florida and I attempted to bake this delish dish as usual but it is not cooking thoroughly. It’s been in the oven almost 90 mins at 325 and it’s still not ready. I’m super bummed. Any advice for perfecting this in high altitudes?

      You could try upping the oven temperature 25 degrees more but keep an eye on the top for browning and tent with foil as needed.

  • Betty

    Hi, I’m wondering about end instructions. Do we cool for an hour on cooling rack while in roasting pan bath or take it out to cool? Also do we remove from spring from pan to chill?

    • Jaclyn

      Remove it from the water bath to cool. Then leave in the springform pan to chill. I hope you love it!
