The Pie That Beat Birthday Cake
I stumbled upon this Key Lime Pie recipe in a small downtown shop when I was visiting Savannah, Georgia with my friend, Amie. I made it for my family when I got home and it quickly became a family favorite. It’s requested more on birthdays than cake!
When I make it, I always use our homemade graham cracker crust. It adds a buttery crunch and complements the citrusy filling of the pie. It’s the perfect dessert – creamy, refreshing, and simple to make. I hope you love it as much as I do!

Ingredients Needed
- Graham cracker crust: I prefer to make my own homemade crust, however a store bought graham cracker crust works just fine and save a little time.
- Key limes: Use fresh key limes whenever possible for the most authentic and vibrant flavor. If you don’t have access to key limes, bottled key lime juice is the next best option.
- Egg yolks: This is what gives the pie its smooth, silky texture. You can use the extra egg whites to make this Lemon Meringue Pie topping or these delicious Coconut Macaroons.
- Sweetened condensed milk: This balances the tartness of the key limes with some sweetness and gives the pie a rich texture.
- Optional topping: I like to decorate the top of my pie with homemade whipped cream and key lime slices.
How to Make Key Lime Pie
- Prepare the crust: Combine crust ingredients and press them evenly into a pie plate. Use a measuring cup to press the crumbs down firmly. Bake at 375 for 5 minutes and cool.
- Zest and juice key limes: Zest key limes to get 2 teaspoons, the juice key limes to fill a ½ cup measuring cup. If you can’t get a full ½ cup, use Key West Lime Juice to fill the remaining ½ cup.
- Prepare pie filling: Whisk or blend egg yolks until they are thick and turn a light yellow color. Slowly pour in the sweetened condensed milk into the yolks while continuing to mix. Gradually add the key lime juice and zest until blended.
- Bake: Pour the filling into the graham cracker crust pie shell. Bake for 15 minutes, then cool to room temperature and refrigerate until ready to serve.
Frequently Asked Questions
If key limes aren’t available, Nellie and Joe’s Key Lime Juice is the next best option. Regular limes can be used as a last resort, it does change the taste slightly, however many of our readers have commented that they’ve used limes and the pie turns out great.
You can do either. Chilling the crust for an hour will set it, but baking it gives it a slightly toasted, firmer texture. Just make sure the crust is completely cooled before adding the filling.
The baking time of 15 minutes is pretty accurate, but elevation and ovens do vary. The filling should look set and only slightly jiggly in the very center of the pie, if at all. The top of the pie should not be browned at all.
Yes, this is a great make ahead dessert. You can prepare the pie a day in advance and keep it refrigerated until ready to serve. It actually tastes best after chilling for several hours.
You can. Bake and cool the pie completely. Wrap it tightly in plastic wrap and freeze for up to 2 months. Thaw it in the refrigerator overnight before serving. Wait to add whipped topping until after the pie has thawed and you are ready to serve.

We want to hear from you! Please leave a review.
I made this last night. I found it to be way too sweet. Next time I will use a cup and a half of lime juice and five egg yolks.
Love this recipe! Thanks for sharing!
How do you add the meringue topping? Do you bake the key lime first then reduce the temp and add the top and then bake the extra 10 minutes or add the topping before baking the key lime?
Hey Gemma- Usually we don’t go meringue topping on the Key Lime pie but if you would like to, you can use these instructions from our lemon meringue pie: https://www.favfamilyrecipes.com/moms-lemon-meringue-pie/ Hope this helps!
Absolutely perfect. I have tried many that did not set up or were too sweet. This is as good as the restaurant with the best key lime pie where I live. Thanks for sharing.
Thank you for the compliment! I love this recipe. It turns out perfect every time. I’m also a fan of the tartness of the pie. I’m so glad you like it!
Excelent recipe !!! It was a hit !! Will make again !!!
Can this pie be frozen? How long will it keep frozen?
We haven’t tried freezing it before but it I’m sure it is possible. I wouldn’t keep it frozen than more than a couple weeks, if it were me. I don’t like the freezer flavor so the less time in the freezer (at least for me) the better!
Love this recipe, I use 1/2 cup of freshly squeezed key lime right from my tree! Perfect pie everytime!
Love that you have a lime tree. Now I want one! 😀
Sounds very delicious, as I live in Brazil, can you tell
me what the crackers are and what can I use as a substitute.?
We have wonderful limes here in Bahia , can I use all this juice etc.
Thank you so much.
Hugo Skucek
Hi Hugo– Graham crackers might be tricky to find in Brazil. If you can’t find them, you can use Nilla Wafers, ginger snaps, or any kind of plain vanilla cookie. Even animal crackers. Hope this helps!
How far in advance can you make this? This looks like a good recipe and I can’t wait to try it.
You can make this probably 2 days in advance … I wouldn’t do much longer than that. Hope this helps!
I can’t find key limes in my local store, can I use regular lime juice?
Yes you can, they just won’t have that key lime tangy-ness. Hope this helps!
I am not huge fan of Key Lime pie but husband loves it. I made this recipe a couple of weeks ago and he said it was the best ever. I tried it and I really liked it. I am making it again today. Thank you.
So glad you and your husband liked it! This is our favorite recipe for Key Lime Pie hands-down (and we are big fans too)!
Do you have to refrigerate the pie to firm it.I put it in the oven at 350 degrees and it rose up some but still had a lot liquid.so I put it in refrigerator.
That should be totally fine. If it was still liquid-y I would but it in the refrigerator to firm. Hope this helps!
This may be a silly question but would it be okay to just use a 1/2 cup of fresh squeezed lime juice?
Yes, you can definitely do that. The key lime juice has a slightly different flavor, but either will taste great!
Can we use lemon instead?
Yes, it will absolutely work with lemon. We also have these lemon pie recipes you can try:

This was delicious, and so easy. Thank you for helping me find my go to key lime pie recipe!
Thank you for taking the time to comment! Glad you liked it 🙂
all one has to do is remember the color of the inside of the lime….it is never bright green. Take it from there.
I’m so excited to make this! This may sound like a dumb question, but in your ingredients you say you need 1/4 cup lime juice but in the method it says you put half a cup in. Is this on the basis that you’d be getting 1/4 cup from the actual lime but then you must add another 1/4 cup of lime juice? Sorry, it’s probably a silly question but I don’t want to accidentally make the most sour pie in the world haha. Thanks x
That is right, you use 1/4 c. fresh and 1/4 c. of the key lime– making 1/2 c total
In this particular recipe for the key lime pie….notice the canned milk used, it is very sweet, and believe me condensed milk takes
it to another level of sweetness. So go ahead and use what the recipe indicates. No fear!
There are many recipes out there for this pie, and i have tried them all……
I had the same question!
you use 1/4 c. fresh and 1/4 c. of the key lime– making 1/2 c total. Hope this helps!
What if I live in Missouri & it’s January & I can’t use Key limes?!
hmm… if you are in desperate need of key limes you could probably find a place that will ship them to you!
If you live in St.Louis Dierbergs market carries key limes. But it is not necessary..I use the liquid from Nellies & Joes and it tastes fine. I have made at least 5 of these pies this month. It has been so cold and this just screams…warmth and sand and sun!!!
Couldn’t agree more!
that is easy….ever heard of Roses lime? Used
in making margaritas…..it works in a pinch…
And it is tasty.
Sel, with all due respect, as the owner/operator of a chain of nightclubs, we use Rose’s in mixed drinks, but my opinion is that it has a twinge of bitterness after taste to it, which might not translate well into this recipe. Same as grocery store bottled lime juice (ReaLime brand), which is not nearly as clean and bright in flavor as real squeezed limes. Although, its companion brand “ReaLemon” is totally satisfactory to use in place of real squeezed lemons, and does not have that “off” after taste that Rose’s and ReaLime has. Note, that I have not tried your suggestion in this recipe so I could stand corrected. Just a cautionary.
You can make this with regular limes. Key limes are preferred, but if you can’t get them, just use regular limes. Also, most markets sell key lime juice. That is another great option. But don’t sweat this – it will still taste great either way. 🙂
I have made this pie on 3 different occasions and it has been a crowd pleaser. As others have noted, this is a very easy recipe to follow to achieve a well balance of flavor and creamy textured pie.
I made this key lime pie for Sunday dinner and my family said it was the best key lime pie ever. I loved that it was so easy to make.
I love, love, love Key Lime Pie!!!www.lifeofamodernhousewife.com
