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!)

Followed the recipe exactly, except I bought a pre-made graham cracker crust and I added a drop of green food coloring to the pie mixture. It turned out exceptionally well. The flavor was wonderful. Not too tart, not cloyingly sweet. The texture was perfect, creamy but firm enough to hold its shape when cut. I covered the entire top of the pie with whipped heavy cream and garnished with zested lime. It was beautiful and our resident key lime pie connoisseur proclaimed it to be the best he’d ever tasted. This will be my go to recipe from now on. Thank you, Trish!!

Made this once for my dads birthday, now for any holiday or birthday or event this is what I’m asked to make and bring!! Over time I’ve slightly adjusted the recipe; a dash of cinnamon in the pie crust, a pinch of salt in the filling, maybe a little extra sour cream or lime zest to cut the sweetness but it’s perfectly good as is. This is a guaranteed hit for any occasion
Tigger says
This Keylime pie is truly the best that I’ve ever eaten or that I have ever made! I’ll never make anything else but your recipe. I feel like a five star chef every time I serve your recipe for the Keylime pie. Thank you thank you thank you
Cynthia says
My family’s favorite pie by far!

I love this recipe, but I did tweak it a little. Since I prefer more of a tart pie, I used one can (14oz) of sweetened condensed milk instead of 2, and I used gluten-free graham crackers (Pamela brand) because I like them better than regular graham crackers. Delicious, and I now have a go-to dessert for my gluten-free friends.
Maura says
Oh my gosh, this is such a delicious and easy key lime pie. Thank you so much for the wonderful recipe.
Irene A Ryan says
Easy and delicious. New go to dessert. Made one and ate it all by myself.
Georgette says
I no longer have to try out any more recipes for key lime pie! Made this pie by request 2 weekends in a row for the same family members, one of whom wanted it for her birthday who had it couple years prior for her birthday. Skipped a weekend and am about to make 2 more by request of same family members for a family cookout! It is very easy and so delicious. I thought it had the right amount of tanginess with the lime and sour cream. I ordered bottled key lime juice from Amazon. Used regular limes for my lime zest using a microplaner for fine zest. Plan to make limeade with the zested limes. Topped one pie with whipped cream and the second one with meringue by request. Delicious both ways. The additional time for baking the meringue in no way seemed to affect the pie itself. A 9.5″ pie pan contains all the filling. With no eggs in the filling, though, if you have any filling left over, the cook gets to eat the little bit leftover! 🙂

Thank you so much!

Your pie is delicious. Thank You
Norma Cotter says
This sounds so good, but I do not like the taste of sour cream. Can this be made with cream cheese?
Trish - Mom On Timeout says
You can sub in Greek yogurt if you prefer but you do not tastes the sour cream at all in this recipe.
Kristy Pickering says
If I could give 10 stars I would. Superb recipe! I even used organic lemon juice because I didn’t have enough lime juice. It’s really great and really only bakes for 10 minutes. I can’t wait to eat the rest of it and make it again!!
Erin says
Best key lime pie recipe!
Amanda says
This tastes absolutely AMAZING. I used the juice from the two (regular) limes and then added the rest from a squeeze bottle. The only thing was I’m not sure if I did something wrong, but the graham crust stuck horribly to my glass pie pan. Next time I might just cheat and use a premade graham crust. But oh that filling was divine! And SO unbelievably easy! Thanks for sharing.
Erika says
After making this multiple times, I realized I had not rated it. Absolutely the BEST Key Lime Pie I’ve ever made OR eaten! I made 3 today, with one going to a 24 year old who swears the major brand frozen pie is the best…..I imagine she will change her mind!
JHM says
I have made this several times now, and it always comes out perfect. A foolproof dinner guest pleaser! I make it with slightly less crust and use about 5 garden variety limes. Perfect.
Mike Meyer says
