Key Lime Pie
I’m admittedly not much of a pie person. I only share pie recipes that I absolutely love. Recipes like this Key Lime Pie. That incredible combination of tart and sweet is absolutely irresistible and will make this pie a family favorite, guaranteed.
So, confession time. I didn’t squeeze a bunch of key limes for this pie. This is an easy key lime pie recipe, after all 🙂 I used key lime juice. You can find it the produce area in most grocery stores. It makes this pie even easier to make!
Now, if you have access to key limes and want to squeeze them, go right ahead! Absolutely perfect in this pie.
After all of that, Happy Pi Day! With an electrical engineering degree you can bet I’ve had my fill of pi. But never, NEVER will I have my fill of this pie.
So this “key” lime pie recipe is crazy easy. And I mean cray-zee. So easy, you may find yourself making one a week, like I plan to, for the rest of your life.
Key Lime Pie – Always Start with a Graham Cracker Crust
The pie starts with a graham cracker crust. I am terrible at crusts but gosh darnit, a homemade graham cracker crust tastes WAY better than a store bought one and it’s pretty simple to make. Just some graham cracker crumbs, sugar and butter will do the trick.
I’m a big fan of graham cracker crusts because they are super easy to make and go so well in many desserts. I use it in this Pistachio Pie and these No Bake S’mores Cheesecake Bars.
(Extra graham crackers? You can find all my recipes that use graham cracker crusts here.)
What Is In Key Lime Pie Filling
Now let’s get to the filling. It’s a whole lotta lime juice, lime zest, sour cream and a couple cans of sweetened condensed milk (a.k.a. nectar of the gods). You just whisk it all together, pour it into your pie shell, bake for 10 minutes and voila – you’ve got a key lime pie that will blow your family and friends away.
- Key Lime Juice
- Lime Zest
- Sour Cream
- Sweetened Condensed Milk
What You Need To Make this Key Lime Pie
- Pie Plate – I made this pie in my 9.5 inch Pyrex pie plate. You can use a smaller pie plate no problem. You’ll either have a little extra crust or just make it extra thick. The filling does not expand when baking so go ahead and pour as much of it into your crust as you can.
- Key Lime Juice or Key Limes – I used key lime juice. I actually order mine on Amazon. I’m a big fan of reading reviews to make sure I get the very best product. This is the one I’m currently crushing on. Truth time. This pie can be made with regular limes if you can’t find key lime or key lime juice. Just sayin’.
- You’re going to need a zester for this pie. The key lime zest adds SO much flavor to this key lime pie and looks so pretty on top!
The truth is, I’m not much of a decorator when it comes to pies and cakes. I’m all about simple, easy, get-it-in-my-mouth-as-quick-as-possible. You too? Good. Then you’ll like my no-nonsense whipped cream topping.
If you are in a hurry, and I mean, a BIG HURRY, I would perhaps allow you to use a store bought pie crust and a can of whipped cream. This pie would still be heavenly. No doubt. (Edited to add: I made the crust in the video but as we were running out of time, I used a can of whipped cream in the video below. Works in a pinch!)

No luck on finding key lime juice at the market but found key limes. In case you’re wondering, it takes 3 tractor trailer loads of key limes to generate 3/4 cup of lime juice. (Just kidding!) I followed the recipe exactly and I am extremely pleased with the results
Trish - Mom On Timeout says
LOL! I know, they are SO tiny! Thank you Jeff!
Carrie Errer says
First time making key lime pie and it was delicious! Will definitely make it again!
Simara says
This is the easiest pie to make. I have made it several times in the past few years and people have told me it’s the best Key Lime Pie they ever had. They want to know my secret. I even had people that don’t like Key Lime taste it and comment that they enjoyed it. I highly recommend this recipe to all the busy people that need an easy recipe or someone that doesn’t bake that often. I would give this 10 stars if I could.
Mary says
This pie is a HUGE hit. Everyone raves about how great this pie tastes. It truly is deceptively easy it is to make, especially considering the accolades it consistently receives. Two enthusiastic thumbs up!
Susan Angell says
Oh my gosh this was so good! I’ve never made it and not sure I’ve ever had it but this was delicious and will be made again and again! I put a little lime zest in the whipped cream too, gave it a nice zip.
Leopold Damm says
I read your Key Lime Pie receipe several but did NOT see any eggs, yolks or flour in it, what holds it all together.
I did not want to make it in fear it will not hold up.
Trish - Mom On Timeout says
It will hold together. Trust me!
Michael Cothran says
Made this for the first time a few weeks ago and making it again today. This pie soo easy to make and tastes great. Makes someone who never made a pie look good. Thanks
Sybil says
This is wonderful! I thought making a key lime pie would be intimidating, but it wasn’t. Ok, juicing all those little limes was a bit challenging (cut into quarters, and use a garlic press), but the rest was easy!
I made a couple of changes to mine. I toasted some nuts, and ground them to mix into the crust (Yum). I also used one regular condensed milk, and one fat free. You can’t tell the difference. Too bad I can’t add pictures!
I’ll be making this again because I’ve had requests for samples.
Trish - Mom On Timeout says
Thank you so much Sybil!
Jimmy Hemphill says
This is a wonderful pie. I’m also an engineer, a chemical engineer with particularly bad lab technique.
I’ve made several. They were super easy to make, even with my poor lab technique, and a resounding hit with everyone .
The last one I made I added 1/4 cup of pureed Maraschino cherries. The pureed cherries turned the color of the pie pink. I used the extra cherries as garnish. I called it a Cherry Limeade Pie. It was a huge hit.
Trish - Mom On Timeout says
Cherry Limeade Pie – love it! Definitely will need to give that a try!
Desiree says
This is the first key lime pie I have ever tried but I brought it to an event I catered and it was a HIT! I had people asking if they could have the recipe. I love it and will continue to use this recipe anytime I am making a key lime pie.
Trish - Mom On Timeout says
I’m so glad Desiree! Have a great week!
Ola says
This is the best key lime pie I’ve ever had. It was my first attempt to make it myself and it worked like a charm. The pie looks totally amazing and it tastes even better. I’m never buying a key lime pie again! This one is thousands times better!
Austin says
Is there any reason why this recipe wouldn’t work with a merengue topping? I love my grandmothers chocolate pie with merengue recipe and I’m wondering if it’ll work as well on this pie. Thanks.
Trish - Mom On Timeout says
A meringue topping would be beautiful! And it should 100% work. This is similar to the filling for a lemon meringue pie so I think you’d be fine.
Amy P says
I only have regular sour cream. Why do you use light? Will it work with regular sour cream? Thanks!
Trish - Mom On Timeout says
It will Amy! Enjoy!
Kim says
Are you positive it’s 3-1/2 cans of condensed milk
Each can is 300 ml and 28 oz is 828ml
Trish - Mom On Timeout says
My cans are 14 ounces each, so 2 cans.
Rose says
Made this last night, could only get about half as much juice as needed from a TON of real key limes, so substituted regular lime juice to get the 3/4 c needed. I used a pre-made crust to save a little time. This recipe was SO EASY and my boyfriend LOVED it. This is his favorite pie, about 3 times a week he’ll tease me by saying “did you say you made a key lime pie today?” and last night I got to show him! He loves it. I’ll be making it again, but I’ll be looking for bottled key lime juice online, I think. Those suckers are hard to squeeze and for so little juice, lol!
Trish - Mom On Timeout says
I totally buy my key lime juice now too Rose. It takes too much time to squeeze them lol! So glad you guys enjoyed the pie! Have a great weekend!
