Key Lime Pie is one of my husband’s favorite pies. For years, I professed that I didn’t particularly care for it. I always thought they were a bit too dense and either too tart or not tart enough. I’m picky, but I thought there had to be a fine balance and wanted an updated version of the classic.

So, I experimented until I created absolutely the best key lime pie I’ve ever tasted!

Favorite Key Lime Pie Recipe

After experimenting with various changes in the method of making a this classic pie, along with subtle changes in the ingredients, I finally achieved a lighter, fluffier pie. It’s pure perfection in my opinion, as well as those to whom I’ve served it. It’s now my go-to key lime pie recipe.

How did I create this updated version of this pie?

How to Make Key Lime Pie

Well for one, I use the whole egg.

While the egg yolks give the key lime pie such richness, the egg whites help to give the pie a lift. It alters the texture from a dense, thick custard to a silky, cloud-like confection. It might not be for everyone, but everyone that I’ve served it to has absolutely raved about it.

The second thing I do is add in a bit of zest from the limes. Along with the lime juice in the recipe, the fresh lime zest amps up the lime flavor and makes the pie a whole lot more interesting and well, zesty!

Another important part of this pie is my easy homemade Graham Cracker Crust recipe. It’s simple to make, but if you are short on time you can always use one from the store. I just think homemade crust is so much tastier!

Along with adorning the pie with fresh lime slices, this pie would not be complete without topping it with my Perfect Whipped Cream. It is the crowing glory to this airy, light and zesty dessert that you really don’t want to miss.

This pie is perfect anytime, but I especially love to serve it in the warmer months of the year. It’s one of the most refreshing desserts and always a hit.  I really do believe it’s the best and hope you think so too!

Instructions

  • Preheat oven to 325º F.
  • Whisk egg yolk, sweetened condensed milk, lime juice, lime zest, and lemon juice in a large bowl until well-combined.
  • Beat egg whites with an electric mixture until they begin to foam. Gradually add in granulated sugar and beat until light and fluffy and soft peaks have formed. Gently fold into egg yolk mixture and carefully spoon into the prepared graham cracker crust.

  1. Hi Tanya,
    Yes! You can use the bottled key lime juice in place of fresh. If possible, I would recommend fresh lime zest, whenever you can. It makes a noticeable difference.

    1. Hi Angela,
      I do not prebake the pie crust for this key lime pie. Of course, you are welcome to but I like the texture of a firmly chilled graham cracker crust that just bakes along with the pie for this pie instead of pre-baked.

  2. I made your Key Lime pie yesterday. Just awesome…so light and creamy. You have some of the best recipes on your
    site. So I’m always trying new recipes that wind up becoming keepers. Thanks!

    1. Hi Robyn
      Can’t wait ti try this key lime pie recipe.
      Two questions:
      1. What size spring form pan should I use?
      2. Can I freeze its pie?
      Thanks
      Darla

  3. Hi Robyn,

    I must say a HUGE thank you for this recipe. My family loved it so much they asked me to make it again. I did change it slightly in that I didn’t use the crust, I made it in a pastry case and it worked out perfectly.

    Thank you again for a slice of heaven.

  4. Best KLP recipe I’ve tried and my son, the world’s harshest critic of KLP, said it was his favorite. Making again today.

  5. I have the question others asked. Although first, what did you make the pie in, pie pan or springform?? And if springform, what size? Looks delicious; want to try it and would rather make in the springform I think…

    1. Hi Charlotte,
      I used a pie plate for mine. You can use a springform pan, if you prefer. I hope that helps! xo

  6. Hi Robyn,

    I love your recipes! This morning I tried to whip up this key lime pie and I struggled with folding in the egg whites. I’m certain that this comes down to my lack of experience. My question for you is: Is it possible to over beat the egg whites? They seemed too stiff and when I tried to fold them into the egg yolk mixture, it broke up into a curdled-looking mixture and didn’t seem to blend in well. Before folding in the egg whites, they were firm but not light and airy, they were rather dense looking.

    Thanks for your delicious recipes! I look forward to trying this one again!

    1. Hi Soulee,
      I’m so happy that you enjoy the recipes! I love hearing that!
      I’m sorry, but it does sound possible that your whites might have been over beaten – especially since you say they were firm and dense looking.
      I hope you enjoy this pie if you decide to give it another try.
      Thanks so much! xo

  7. H Robyn,
    I have never really cooked before so I don’t know my way around the kitchen. I made everything exactly to your instructions. But I don’t own a spring for pie dish. I used a glass one and set the temp to 325 however I almost had to double the time for it to be firm all across and the top was a teeny tiny bit golden. Looked like your picture. Also I made the graham cracker crust to your recipe and did not pre-cook. Should I have? It’s cooling now and will go in the fridge over night. I can’t wait to taste it! The limes were the best from my friends trees. I’ve been using your limeade recipe for a few weeks now. Everyone loves the limeade! So hopefully the pie will be just as good!

    1. Evablue,
      It is fine if you don’t use a springform pan. I don’t pre-bake my graham cracker crust for this pie so you did the right thing. Hope you love this pie. Glad you like the limeade recipe. Let me know how you like the pie.!

  8. I made this for a retirement party and everyone who got a piece actually loved it.  One person couldn’t wait for dessert and took one eighth of the pie when it was actually time to serve it.  The person who was retiring claimed it was the best key lime pie she had ever had!  Thank you for this great recipe.

  9. The key lime pie was extraordinary! I followed your directions to a T and so glad I did. The crust was simple and so much better than a bought one. The pie itself so much lighter and just delicious. My only problem is that I should have made two so I could keep one just for myself!!

  10. Hi there,

    Following your recipes for a long time and whenever I get time I make one of them. All my family member love that. On this weekend I am going to try this recipe.

    Thanks

  11. Hi Robyn! I hope I don’t sound stupid, but is there a difference between key lime juice and regular lime juice? I don’t believe I have ever seen key lime juice in the grocery store( though I never looked for it before). Thanks.

    1. Hi Terri,
      It may be hard to find key limes year round in the grocery store. If you can’t find the key limes in your grocery store, you can use regular limes you find there for this pie. Enjoy!

  12. I saw a quick pic of what looked like either a cake or brownies with small Reese’s Peanut Butter cups and covered with a couple of syrups. What was it and can you publish the recipe? It looked amazing!!’
