Easy Key Lime Pie

Josh can usually pass on dessert. He isn’t the biggest chocolate fan, but when key lime pie is on the menu, he will always have two pieces of pie! It is his all-time favorite dessert! I make him this easy key lime pie recipe every year for his birthday. It is his favorite pie and I am glad because it is SO easy to make. I usually don’t like to mess with pies because they can be tricky, but this one is super easy to makeΒ  and comes out perfect every time. You are going to love it!

How to Make Key Lime Pie

This easy key lime pie recipe has a sweet graham cracker crust, which is SO easy to make. For the crust you need, crushed graham crackers, sugar, and melted butter. That is it! Mix the ingredients together until moistened and press into a pie plate. Bake until the crust is golden brown and you have the perfect key lime pie pie crust!

For the rich key lime filling, you only need 4 ingredients:

  • lime zest
  • lime juice
  • egg yolks
  • sweetened condensed milk

You should be able to find key limes at most grocery stores, but if you can’t you can use the bottled key lime juice. We like this brand. It is really good and a major time saver. There is nothing wrong with shortcuts! You can also use regular lime juice if that is all you can find.

Mix the filling ingredients together and pour in the baked graham cracker crust. Bake until the filling is set, about 15-17 minutes and then let the pie cool completely. We like to chill it in the refrigerator before cutting to make sure it is completely set up before slicing. The pie is great served chilled or at room temperature.

You can serve the pie plain or you can add a dollop of whipped cream! You can also add a lime slice for garnish to make the pie extra pretty!

    I love this one – I will be making it this very weekend – thanks for sharing x

  4. Maria, Happy Mother’s day and happy B-day to Josh! I would love a piece of pie now…just a wee dollop of whipped cream on it, please.

  5. Yumma Yumma!! Looks fantastic and so refreshing πŸ™‚ Have a great Monday!! Still haven’t decided about the Photo workshop, I’ll decide by the end of this week.

  6. Josh is a lucky man to have you for his wife. The pie looks delicious. I would have used regular limes, too. Those key limes are just so tiny.

  7. What a sweet wife making your husband all these great goodies on his birthday! Im sure he felt very blessed! I have a killer key lime pie recipe my mom shared with me about 3 years ago. I have not made any other since..this recipe looks great and your pie looks so refreshing. My family loves key lime pie. I think it’s a perfect summer dessert! Thanks for sharing and tell your sweet Josh Happy Birthday!

  8. We love Banbury Cross!! It is dangerously close to our house and a Saturday morning treat about once a month for us. πŸ™‚ This pie looks great as well! Love anything lime!

  9. Mmm, you’re a lovely wife to make such goodies for your man. πŸ™‚ I like that you added lime zest to the mix. That would make it even better for sure!!

  10. I love birthday cooking too! Have you ever made key lime pie without egg yolks and froze it? It’s delicious. I think Ina Garten has a recipe for frozen key lime pie…It might be Josh’s new favorite!

  11. As I started reading this entry I was planning to ask if you thought using normal limes would work (as I have about 20 too many in my kitchen right now) and then you answered my question perfectly! I’ve been craving a key lime pie/ just lime pie the last couple days so I’m glad you’ve put this recipe up. Can’t wait to try it!

  12. Key lime in Asia is not used in pies but drinks. This is a great recipe. I never though key limes could be used as limes and lemons.

  13. Happy birthday Josh!

    you guys are so cute….never fails to make me happy.

    I love lime desserts and will definitely have to give this a try. The graham cracker crust is a MUST.

  14. My family loves key lime pie – especially when it’s “wicked taht!” (if you don’t know where I’m from already, you probably do now!) Happy birthday, Josh!

  15. This looks wonderful, Maria. I’m sure it tastes every bit as good as it looks. I hope you are having a wonderful day. Blessings…Mary

  16. Happy Birthday to Josh! Looks like he had a wonderful birthday pie. Now I’m off to check out your bars. I want to make a lime coconut bar.

  17. One of our best friends asked for this for his birthday too. I’m thinking of trying to make a key lime pie cupcake as a surprise for him.

  18. This looks so good! To be perfectly honest, I don’t think I’ve ever tried Key Lime Pie. Now that I think about I’m wondering how that’s even possible, but I really think it is. I’m going to make this for dinner this coming Saturday. I’m so intrigued to see what I’ve been missing out on!

  19. One of my friends makes a fantastic key lime pie, but i have never gotten around to asking her for the recipe. Thank you for posting this, i will definitely try it! πŸ˜€

  20. I’ll have to try this Key Lime Pie recipe! I’ve been on the search for a great recipe and this looks like a winner!

  22. Saw this on Make&Takes and had to give it a try. I used a different crust (I was trying out a graham cracker from scratch — no packaged crackers– so the crust I made wasn’t exactly easy!); but the filling was awesome and totally redeemed my dinner last night! (I made an AWFUL calzone for my hubs, but) your dessert redeemed me!

    I will definitely be checking your website out more often.

    Thanks for the idea.

  23. I was born and raised in Key West…your key lime pie is authentic! (well except for your lime juice) So often the key lime pies you see outside of south Florida are crazy lime flavored concoctions that are not even close. Just wanted to tell you about Nellie and Joe’s Key Lime Juice. It’s bottled key lime juice that is all we Key Westers ever use. πŸ™‚

  24. I LOVE key lime pie, but I’ve found that anything made w/ sweetened condensed milk gives me such a sugar-crash it’s just not worth it. Anybody know of a recipe that uses cream or something instead?

  25. Why didn’t you just call this pie lime pie? Key limes are yellow and quite different. The term “Key lime” is misused so often

  26. I didn’t say the pie would not be great, I said that it was not Key Lime Pie, it is just plain old Lime Pie. some cooks actually color a lime pie green I guess because the skin of a lime is green, but when they color a pie they are calling Key Lime pie green they are really misrepresenting …key limes are yellow, inside and outsice

  27. Great recipe! I used this for a party with friends who like fruit pies best for dessert and it was a big hit! The extra zest was perfect, as I prefer a more tangy lime flavor. I would be interested to try it sometime with key limes to see if the flavor is any different. (By the way, my limes must be HUGE because I only had to use 2 to get a half cup of juice, not 5!)

  28. Just wanted to let you know that I made this pie for Easter as I said I would. It was fabulous! The only problem was that I didn’t bake 2 because everyone wanted more. Thanks for another great recipe!

  29. This is the recipe I’ve been using for over 20 years and always get raves. A step-daughter requests it every time she visits. I sometimes use a regular crust and always top with real whipped cream!

  30. Any thoughts on how far ahead I can prepare this before serving? Β  Assuming it’s refrigerated is 48hrs too soon?!

  31. The key lime pie recipe is a wonderful pie! Β Not only does it taste good, it is really simple to make. Β The only thing I would change is to garnish each piece with fresh made whipped cream (don’t tuin it by adding the frozen stuff!). Β 

  32. The pie , out of the over looked fantastic! I can’t wait to chill , garnish and fast it. Will post again when it’s ready to eat. Thank you for this simple pie recipe.

  33. I made this recipe a few weeks ago using limes from my grandpa’s farm and it was lovely! Is there anywhere I can upload the photo?

  34. Just made this and it tastes amazing. But mine is a bit runny. Not as firm filling as in your photos. what can I do next time to make sure it’s firm?

  35. I like its simplicity…I used regular crust and made a merangine…I had to improvise too hot to make a store run so I used what I have. It was a great way to use the whites..hate to waste food..its baking now.proof is in the pudding or should I say

  36. Hi there,

    Quick question. When you mention 1 1/4 cup of crumbs and 1/2 cup of lime juice, what’s the measurement like for β€œcup” in measurement like ml ? Is there an international measurement for β€œcup”?

    Sorry first time trying this receipt.Β 

    1. Key limes are harder to find so you can use regular limes. You just need 1/2 cup juice. You can even use store bought key lime juice.
