This key lime pie ice cream tastes just like a classic key lime pie, only deconstructed and frozen. Just 7 ingredients and 30 minutes of prep WITHOUT an ice cream maker!
No Churn Key Lime Ice Cream
I originally shared this Key Lime Pie Ice Cream over on Spend With Pennies, but wanted to share it with you here, too!
Today we’re taking classic key lime pie and turning it into a frozen, summer-friendly treat. This no-churn ice cream has all the flavors of key lime pie: a bright (but not over-powering) pucker of key lime, a creamy, sweet-tart base, and a crisp and buttery rumble of graham cracker crust swirl.
Even better, this recipe requires absolutely no ice cream maker, eggs, or cooking on the stove. Instead, we’ll take just stir together a handful of simple ingredients, fold in some homemade whipped cream, and pour it all into a bread pan. You will have to freeze it for all of eternity (6 hours), but all of the real prep takes less than 30 minutes.
What You Need
It might be hard to believe we’ll get such tasty results from just 7 ingredient’s, but it’s true! Here’s what you need:
- Sweetened condensed milk. This is an essential no-churn ice cream ingredient. It’s what mimics the custard base in most traditional ice creams, and it’s also a classic key lime pie ingredient! Make sure you use sweetened condensed milk and not evaporated milk; while the cans look similar and are sold next to each other, they are not the same thing.
- Key lime juice. I don’t have access to fresh key limes where I live, so I usually buy bottled Nellie & Joe’s key lime juice from my grocery store. Several of you have asked if you can substitute this for lemon juice; I haven’t tried it myself, but I think it would work just fine!
- Heavy whipping cream. Double cream or heavy cream will also work. We will whip this to stiff peaks and then gently fold it into our ice cream base.
- Graham crackers. You want to crush these into crumbs, but make sure to leave some small, bite sized pieces too for a little texture. We will combine these with a little melted butter (salted or unsalted, it’s such a small amount either works fine) and sugar to create that classic graham cracker crust.
- Vanilla. Just a splash in our graham cracker swirl adds such a nice flavor. Homemade vanilla extract would work nicely here!
SAM’S TIP: Want some extra lime flavor? Add some lime zest into your ice cream! Just make sure you don’t zest too far down into the pith of your lime (the white papery part), as that can be bitter.
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 It
Graham Cracker Swirl
- Combine the vanilla and melted butter in a small bowl.
- Add the sugar and graham cracker pieces and use a fork to stir until well combined. Set aside.
Key Lime Ice Cream
- Stir together the condensed milk, key lime juice, and vanilla extract in a large bowl.
- In a separate bowl, whip the cream until it reaches stiff peaks. You will know you’ve reached stiff peaks with the mixture is thick, fluffy, and holds its shape when lifted out of the bowl.
- Fold the whipped cream into the condensed milk mixture until combined.
Assembly
- Pour half of your ice cream mixture into a wax paper lined bread pan.
- Sprinkle half of the graham cracker mixture over top.
- Add the second half of the ice cream mixture, then sprinkle the remaining graham crackers on top.
- Cover the ice cream with plastic wrap and place in the freezer to chill for at least 6 hours, preferably overnight.
SAM’S TIP: If you struggle with whipping cream to stiff peaks, try using metal bowl and beaters and placing them in the fridge or freezer to chill for a few minutes beforehand. The cold bowl and utensils will help tremendously.
Frequently Asked Questions
You can use regular lime juice if that’s all you can find, but the flavor won’t be quite the same. If you can’t find key lime juice in the juice aisle of your grocery store (it’s usually sold right near the lemon and lime juice), you can always buy it on Amazon.
This is a no churn ice cream recipe, so it’s designed to be mixed and immediately frozen–no ice cream maker needed. That being said, it might still work in your ice cream maker, but I just don’t know for sure. If you do try making it this way, let me know how it goes in the comments below!
If you can find sweetened condensed coconut milk and coconut cream (plus non-dairy butter), it might just work! I haven’t tried this myself, but I suspect it would turn out fine. Plus, lime and coconut go great together (especially in my island cookies!), so the flavor should still be tasty.
If you love the sweet-tart tropical flavors here, you’ll definitely want to check out my key lime pie cookies or key lime cheesecake next!
Enjoy!

Hi! I am so happy to have found this recipe! My husband and I traveled to Canada last spring and while there I bought a pint of key lime pie ice cream from a brand that we also have in the US. I fell in love with it and quickly became obsessed. Imagine my distress when I discovered this brand only produces it in Canada. I then couldn’t find any other brands in the US to make this flavor, but then you and your recipe me along. I made last night, literally tried first thing this morning. Amazing!
I’m so glad you enjoyed it so much, Jen! 🙂
SAM, IS ROSE’S SWEETENED LIME JUICE CLOSE TO KEY LIME JUICE? READY TO MAKE SOME ICE CREAM!! CAN’T WAIT.
Hi Sherry! Unfortunately since that juice is sweetened, it won’t work here. You can use regular lime juice instead of key lime if you can’t find it in your local grocery store; the flavor will just be a little different. We hope you love the ice cream! 😊
Hi! Could you possibly explain the reasoning behind this? Is it because the added sweetness would be extremely overpowering and thus would ruin the balance between sweet and sour?
Hope to hear back! Thanks for an amazing recipe!
~Mariah
Correct! We’re looking for pure juice here, which shouldn’t be sweetened.
Hi! Does this recipe have to use Key Lime, or can I use any type of lime? Thanks for your great recipes!
The flavor won’t be the same if you use a different lime, but it could still work.
Your definitely not alone. I apologize if I bump into something, I apologize for things I didn’t do, and even once I apologized for taking a test in the wrong color! And yes, I apologize for being too apologetic. I love this ice cream! Even when it’s cold out it’s still nice and refreshing. Quick question: is there a way to make this a lemon ice cream?
I am so glad that you enjoyed the ice cream, Kayla! You can experiment with making it a lemon flavor for sure! I personally haven’t done so yet. 🙂
Maybe add lemon juice in place of key lime and add lemon zest to the crust? I want to make it for a summer party and was hoping to do a lemon and a lime.
Hi, Kayla! That should work. Keep me posted on the results. Sounds delicious! I also have a lemon cream pie you can try as well. 🙂
Thank you! I’ll try that and keep you updated!
I say “I’m sorry” all the time. I try to catch myself now.
This is everything I want in an ice cream! I love key lime pie. I need a big scoop of this and a hammock to sit in! ?
Glad I’m not the only one! Thank you, Amanda! 🙂
I’m the same way, Sam! If I bump into the wall I say, “sorry” as if it’s going to reply. Haha. This ice cream looks amazing! I love all of these summer recipes the problem is choosing which one to make first. 🙂
Hahaha, I’m so glad I’m not the only one! Thank you, Hira, I’m glad that you are enjoying the recipes! 🙂
