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!)

Thank you for sharing this recipe! My father in law requested Key Lime Pie for dessert & since I had never made one from scratch before I told him I’d give it a go! My FIL is a pie connoisseur of sorts, lol so I crossed my fingers that he’d like it…well he didn’t just like it, he loved it! The rest of my family are not big pie people but this got the overwhelming request to make it again & soon from everyone at the table! This will surely become a recipe I use for many family functions to come!

I tried this recipe over the weekend. It is absolutely amazing! It was as good as my favorite made by Skates on the Bay in Emeryville, CA. Their Key lime pie is very very good and is quite popular, so I was excited to see just how good this recipe was. I followed the recipe exactly and it was a huge hit.
Definitely use the best quality key lime bottled juice she recommends (found on Amazon).
One more tip, though I didn’t have any when I made this over the holiday. Skates on the Bay serves this with lemon sorbet on the side to make it even more delicious. Since its very rich I think the sorbet cuts that richness a bit and makes it even more special. If you really want to impress big time, Skates also serves this over dry ice.
Thank you so much!!
