Welcome to my kitchen. I hope to inspire you to grow as a home cook!
There’s something magical about desserts that hit you with both creaminess and tang—and this no bake key lime cheesecake recipe does just that. It’s rich, smooth, bright and zesty and it’s the perfect warm weather dessert.
All of this is on a perfect graham cracker crust with the right about of crunch. And the best part? You don’t even need to turn on your oven.
This easy lime cheesecake is built for summer. It’s the kind of dessert you whip up when it’s too hot to bake but you still want to impress. Whether it’s for a barbecue, birthday, or just because, this one’s going to shine.
Ingredients:
Graham Cracker Crust
- 1 3/4 cup graham cracker crumbs
- 1/2 cup melted butter
Key Lime Filling
- 2 8oz cream cheese blocks, room temp
- 3/4 cup sugar
- 1 1/2 tsp vanilla
- 1 lime, juiced
- 3 limes, zested
- 1 cup heavy cream
Instructions:
- In a bowl, mix together graham cracker crumbs and melted butter. Pour into a 8X8 spring pan and press down with a flat bottomed cup. If the mixture sticks to the bottom of the cup, wrap in parchment paper. Once graham crackers are pressed down, place the pan into fridge for 15 minutes.
- In a bowl, use a hand or stand mixer to beat together the cream cheese, sugar, vanilla, lime juice, and lime zest until smooth. In a separate bowl, whip the heavy cream until it forms soft peaks. Gently fold the whipped cream into the cream cheese mixture until fully combined and fluffy.
- Pour cream cheese mixture over chilled graham cracker crust and place pan bake into the fridge, ideally over night or for at least 5 hours.
- Remove and garnish with whip cream and lime wedges! Enjoy!
Why I Love This No Bake Key Lime Cheesecake
I’m a sucker for anything that balances tart and sweet, and this key lime cheesecake recipe is a dream on that front. The lime zest adds a strong key lime pie flavor which is pure perfection.
The cheesecake filling is smooth and fluffy. The graham cracker base gives it a nostalgic pie-like structure. It’s a ten out of ten in every way.
I also love the make-ahead vibe here. Pop it in the fridge the night before, and boom—dessert’s done. It’s simple, effective, and lets the ingredients truly shine.
The Secret to a Solid Graham Cracker Crust
Let’s talk crust. You’ve got to start strong, and for this dessert, that means building a perfect graham cracker crust. We’re using graham cracker crumbs and melted butter—simple, classic, and it works every time. The fat in the butter binds everything together and once it’s chilled, it gives you that clean cut and satisfying bite.
Pro tip: Make sure the crumb mixture is packed in firmly and evenly. I like to use the bottom of a glass to press it down into the springform pan. Chill it for at least 15 minutes while you prep the filling—this gives you a base that doesn’t fall apart when sliced.
No Bake Key Lime Cheesecake Filling
Alright, here’s where it gets good. The cheesecake filling is what takes this from just another lime dessert to a full-on summer showstopper. Start with full-fat cream cheese (no cutting corners here) and whip it together with sugar until totally smooth. This gives you a base that’s rich, thick, and slightly tangy—exactly what you want from a cream cheese mixture.
Then comes the flavor punch: real lime juice and loads of lime zest. I like to zest three full limes into the mix. That’s where you get the aromatic oils and bold key lime flavor.
To lighten things up and give it that luscious mousse vibe, fold in freshly whipped cream. This isn’t the time for shortcuts—use real whip cream and beat it to soft peaks before folding it in gently. It’s that extra step that creates the dreamy texture people go nuts for.
Time to Chill Out
Once your filling is in the crust, smooth it out and transfer the whole thing to the fridge. This step is non-negotiable. The chill time (at least 6 hours, ideally overnight) gives the no -bake key lime cheesecake time to set into those picture-perfect slices. The texture goes from loose to sliceable, and the flavors meld into one cohesive, delicious bite.
Tips For Your No Bake Key Lime Cheesecake
- Cream Cheese: Stick to full-fat for best results. Low-fat can lead to a runnier filling.
- Lime Juice: Fresh is best, but if you’re in a pinch, bottled key lime juice will still bring a lot of flavor.
- Graham Cracker Crumbs: Sub in crushed digestive biscuits or vanilla wafers if you want to mix it up.
- Whip Cream: Heavy whipping cream holds its structure better than canned alternatives.
And hey, if you’re feeling inspired after this cheesecake, try using any leftover lime zest or juice in 3 ingredient ice cream for a fresh, citrusy frozen treat. It’s a great way to keep that lime train rolling.
Serving and Storage Notes
Right before serving, run a knife around the edge of the pan for a clean release. Garnish with a sprinkle of extra lime zest, or go all out with piped homemade whipped cream if you’re entertaining. Leftovers store beautifully in the fridge for 3–4 days, though I doubt it’ll last that long.
Why This Recipe Works
This key lime cheesecake is all about balance: sweet, tangy, creamy, and crisp. Quick to assemble, super refreshing, and just the kind of dessert that brings a smile to everyone’s face. There are many key lime cheesecake recipes, but this one’s special. It’s easy, delicious and everyone loves it.
So if you’re looking for an easy dessert that punches way above its weight, this no bake key lime cheesecake is where it’s at. It’s a chill dessert with a sunny twist—perfect for summer, perfect for sharing, and perfect for making again and again.

Andy, this cheesecake was so easy to make at the cottage and a huge hit! I followed your instructions, the cottage was hot, but it came together perfectly after refrigerating it overnight. Everyone wanted the recipe:)
Love this! Thanks for sharing!
Hello Andy!
I am Florida born and raised and grow tired of any recipe called “key Lime” that does not use “Key Limes”. You suggest that the user can use bottled key lime juice or even better fresh squeezed lime juice. I’m all for fresh squeezed lime juice but it has to be key limes. Key limes have a distinct flavor profile that is lost on all other limes. Without key limes it is just a lime pie and you might as well use jello as your flavoring component.
PS: I love your page and use many of your recipes. Keep up the great work!
Cheers,
Thanks for the info, Victor! Appreciate the feedback!
I’ve made this a few times…. it’s amazing and so easy. Texture is perfect. I used fresh raw organic cream and organic cream cheese. So good.
So happy to hear it was a hit, Ramona! Thanks for sharing!
I hate to say this but this came out ok. It was mush but it tasted ok. The consistency was runny and I left it to chill overnight. I followed everything to the T, but I’m so bummed it came out so runny.
Hi Rebecca! A runny texture usually means the filling didn’t set fully — sometimes that happens if the cream isn’t whipped enough, or if it needs a bit more time to chill. You could also add a touch more cream cheese next time to help it firm up. Glad the flavor was still a win!
Saw the post and had to make it! Lime fan here (in NS). Used British Hobnob biscuits as that’s all I had and used an extra lime for juice and zest. OMG! To die for 🤤
Love that, Mairi! Hobnobs sound like a great crust swap—and extra lime is always the right call. So glad you loved it!
