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!

Recipe Review


  1. 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!!’

  2. This is my go to recipe for special occasions…I’ve made it numerous times and it’s absolutely a winner! I lived five years in the Caribbean and this pie is as authentic as the ones I had there. Wondering if you have a Coconut Cream Pie recipe you could pass on to me..
    Thank you,

    You absolutely nailed it with this recipe! The egg whites add the perfect balance to the dense pie. It’s super easy to make and was a huge hit at Easter dinner. This is one of my favorite desserts and I am so happy to have found the perfect recipe!

  4. 5 stars
    This pie is excellent! I made it exactly except I goofed and had the oven at 350 instead of 325. It cracked through the middle but it was not over cooked at all. It’s the first time making key lime pie for me and it was a huge hit. I used regular limes as key limes are not available. Thank you!

    Awesome light and airy dessert bursting with lime flavour! Served 4 adults as noone could stop eating it. 🙂

  6. Would pie crust for this be put in frig for an hour before adding the filling and then baking 15-20 mins with filling as opposed to 7/8 mins in oven for “no bake filling”? Just want to be sure I prepare crust correctly.

    1. Conchetta, 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. I hope you enjoy!

  7. I tried your recipe for Coconut Cream Pie and it was amazing! So I thought I would look up another one of your pie recipes. I am confused on this recipe for Key Lime Pie. The recipe calls for 3 eggs (separated) yet in your remarks above the recipe you say you use whole eggs. My question is, if I use whole eggs is it still 3 eggs or is it less?

    1. Karen, I use 3 whole eggs in this recipe, but I separate the yolks from the egg whites. I add the egg yolks to the sweetened condensed milk, lime juice, etc. as listed in Step 2 of the Instructions. I then beat the eggs whites as instructed in Step 2 and add to the egg/milk mixture. Some key lime pie recipes only add the egg yolk. That’s what I mean by using the whole egg.
