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 husband in the hotel line 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… Thanks for sharing a superb recipe.

Best pie ever!! I made this for my daughter’s birthday and got rave reviews. She shared it with friends and one told her it was so good it could be on the menu at a restaurant. Thank you for a great recipe!!

Finally made the pie. I didn’t have key lime juice bottled or fresh so I just used reg limes. I used a lot more zest than called for. Everyone really enjoyed it. I did experience an issue with the crust though. For some reason some of it stuck to the bottom of the pie plate. I actually used the exact one you did (did you happen to pick them up at Walmart? Lol). Any idea as to why this would happen? I’m planning to make it again. Hopefully today. I’ll check back before I do just in case you answered my question….

More zest is always a good idea! So I make my own crust, it’s really easy to do if you haven’t tried it before! And sometimes, if you go to cut the pie right out of the fridge, the crust can be a little sticky. Let it sit out for 10 minutes or so if you’re having problems. Hope that helps!

Made this to today using limes off of our tree. It was spectacular. Even better than the pies we get in the Keys. I didn’t change a thing. Thank you so much for sharing. Everyone raved about it!
Trish - Mom On Timeout says
How fantastic Melissa! I appreciate that so much! I wish I had a lime tree lol!
Suzanne says
Can you omit the whipped cream on top ??
Looks like your using just a can whipped cream from store in the video ?
Trish - Mom On Timeout says
You can and yes, I used canned whipped cream in the video although that is a poor substitute for the real stuff lol 🤣
Jill says
Delicious I think I ate most of 1/2 the pie myself!
Tammie says
Haven’t made this yet but I just wanted to give a tip for those who plan to make their own whipped cream. If you add some skim milk powder to your cream it will help to stabilize it more. I learned this from Anna from Anna Bakes YouTube channel. Just add 1 tbsp to 1 cup of whipping cream (1:1 ratio). Happy baking fellow bakers…. 😉
Justin says
I tried this recipe and I only have one complaint. I can not stop making this recipe now. It is superb!
