This key lime pie recipe is perfectly sweet with a nutty, delicious hint of coconut. Key limes are zested and juiced to make this silky smooth filling with a crisp graham cracker crust. Serve it these as dessert alongside my grilled portobello burgers or smash burgers!

Have you ever been to Key West, Florida. It’s at the southern most tip of Florida. It’s a magical place where you can visit Ernest Hemmingway’s house (with all his cats), drink in the streets), see the sunset and sunrise in the same place AND, of course, eat all the key lime pie. Authentic key lime pie.

Key lime pie is delicious any time of year but I love it when spring begins to hit and the weather starts to warm up. I love all type of citrus desserts (like these mojito cupcakes and meringues with citrus curd.

Ingredients for Key Lime Pie.

What Is Key Lime Pie

Key Lime Pie is a specialty pie from Key West, Florida. Eating a slice of this heaven while in Key West is a heaven. The best key lime pie traditionally consists of the following:

  • A graham cracker crust. 
  • Sweet custard filling filled with lime flavor. 
  • A meringue topping that’s torched until medium golden brown. 
Egg yolks in bowl with lime zest.

How to Make Key Lime Pie

  1. Make the graham cracker crust. This means combining melted butter, graham cracker crumbs and salt.
  2. Press it into the pie dish. I find it easiest to do this with a cup measure; it really helps pack the cookie crumbs into the bottom and sides of the pie dish.
  3. Bake the crust. 
  4. Mix up the filling. Add the strained the key lime juice and mix it with the coconut milk, sweetened condensed milk, key lime zest and salt.
  5. Pour the filling into the pie crust. I like to open the oven, add the pie dish to the rack and pour the filling to eliminate having to move the pie dish all full with filling.
  6. Bake it until the filling is set! And then let it cool to room temperature and transfer to the fridge for 2 hours to chill.
  7. Toast the coconut flakes (that we’re gonna use for garnish).
  8. Make the topping of coconut cream and heavy cream. 
  9. Add the topping to the top of the pie. 
Meringue going on top.

Tips and Tricks

  • Use a cup measure to help you pack and even out the graham cracker crumbs. This helps a lot!
  • Strain the key lime juice! This removes the pulp which is important! Key lime pie strain!

Recipe FAQs

Can You Use Regular Limes for Key Lime Pie?

You definitely can! I would suggest adding more lime zest; up by 1/2 tablespoon of zest. The pie won’t be as tart and bright, but it’ll still be super delicious.

Can You Freeze Key Lime Pie?

Yes you can absolutely freeze it. Bake the pie and then allow it to cool to room temperature. Wrap it tightly with plastic wrap and then transfer to the freezer. Will stay good for up to 3 months.

This key lime pie recipe is made even more delicious by adding a coconut component. Key Lime Coconut Pie is perfectly sweet with a nutty, delicious coconut flavor.


  • 1 (9-inch) pie dish


Graham Cracker Crust

  • 1 cup finely ground graham cracker crumbs, (from about 8 crackers)
  • 2 tablespoons granulated sugar
  • 1/4 teaspoon kosher salt
  • 6 tablespoons unsalted butter, melted

Key Lime Pie Filling:

  • 1 cup full-fat unsweetened coconut milk
  • 1 1/2 teaspoons finely grated key lime zest, (from about 4 key limes)
  • 1/2 cup fresh key lime juice, strained (from about 12 key limes)
  • 5 large egg yolks
  • 1 (14-ounce) can sweetened condensed milk
  • 1/2 teaspoon kosher salt

Key Lime Pie Topping:

  • 1/4 cup sweetened or unsweetened coconut flakes, (I used chips)
  • 1 cup heavy cream
  • 2 tablespoons powdered sugar


  • To Make the Crust:
  • Preheat the oven to 350 degrees F. To a medium bowl, mix together the graham cracker crumbs, sugar, salt and butter; it should feel like wet sand. When thoroughly mixed, add to your 9-inch pie dish. Press the crumbs up the sides and all over the bottom of the dish until you have an even layer of crust.
  • Transfer to the oven to bake for 10 to 12 minutes, until lightly golden brown. Remove and set aside and allow to cool completely.
  • To Make the Filling:
  • Turn the oven down to 325 degrees F. Start this process by scooping out three tablespoons of the coconut cream that's sitting at the top of the can of coconut milk. Transfer this coconut cream to the refrigerator (we’re going to use it as part of the topping!).
  • Whisk together the remaining coconut cream (if any) and coconut milk together (you can do this in the can). Make sure the clumps aren't super large, some small clumps are ok.
  • In a large bowl, whisk together the coconut milk, key lime zest, key lime juice, egg yolks, sweetened condensed milk and salt. Again, little clumps are ok, but big clumps, not ok–break them up with a fork if they're throughout.
  • I found it easiest to add the filling to the pie dish when it was in the oven—no spillage! Place the pie dish with the crust on a baking sheet and transfer to the middle rack of the oven.
  • Pour in the filling, close the door and allow to bake for 45 to 50 minutes, until the top is firm to the touch yet still a wobbly. Remove from the oven and cool for about 10 minutes. Transfer it to the fridge so it can set for at least 2 hours. It’s a long time to wait but it’s well worth it! If you can do it overnight, even better! The colder the better.
  • Since the oven is already hot, we’re going to toast some coconut flakes.
  • To a small baking dish, add the coconut flakes and allow to toast for about 5 minutes in the oven, until lightly golden brown. Set aside.
  • To Serve the Key Lime Pie:
  • Right before serving, make the topping. By now the coconut cream should be very cold. Add the coconut cream and powdered sugar to the bowl of a stand-up mixer with the whisk attachment; beat until smooth, about 2 minutes.
  • With the mixer running, pour in about 2 tablespoons of heavy cream (eyeball this measurement) and beat until incorporated. Slowly incorporate the rest of the heavy cream until smooth and medium peaks form, about 2 minutes. Just an FYI, you don't want over-beaten whipped cream so do not walk away!
  • Pour the whipped cream on top of the pie and spread it around–get artsy with it. Sprinkle the toasted coconut flakes on top and slice and serve.


Where to buy Key Limes:
If you live in the Los Angeles area, I found my key limes at Gelson’s Grocery Store in Los Feliz. They also sell them at Vallarta Market and Smart & Final. 
Some Things to Keep in Mind Before You Start: 
  • Before you start, make sure you know that this pie has to set in the fridge for 2 hours before serving or else it’ll be a sloppy ol’ mess.
  • Full-fat coconut milk gave me the best flavor and texture (silky smooth!), but lite coconut milk will also work (my first go-around used lite).
  • If you can’t find key limes, you can use bottled key lime juice! For the zest, feel free to use regular lime zest.
  • Lastly, a question I’ll probably get: will this work with regular limes? Yes, absolutely, but I’d increase the zest by about 1/2 tablespoon.

    Baked for over an hour and it’s still completely liquid. I’m an experienced baker and followed recipe, not sure what happened. Doesn’t seem to have anything in it to thicken the batter. I do not recommend.

  2. 1 star
    Not a reliable recipe. Should have taken the warning from other reviews saying it wouldn’t set. Stayed so runny while in the oven that I was left to keep baking it, which burnt the graham cracker crust. Only good thing was the whipped cream topping.

  3. 5 stars
    I’ve made this recipe 3 times and it quite possibly the best pie I’ve ever tasted. Came out perfect every time. My husband ate an entire pie in less than 24 hours. Thank you for the amazing recipe!

      1. 5 stars
        I’ve made this pie probably 10 times in the past 2 years and it’s always amazing!! I don’t even like coconut generally, but this pie slays. I have family members randomly ask me to make it. The only things I adjust: I add some toasted coconut to the graham cracker crust & I use extra lime zest becuase we like it bold. I’ll never use another recipe!

  4. 5 stars
    Around our home, when food is exceptionally good, we call it stupid good. Well, this pie is stupid good – the best I’ve ever tasted! The filling is silky, creamy, goodness and the key lime is not overpowering, nor is the coconut. It just all comes together as this perfectly balanced, wonderful key lime pie. You could serve this to anyone – your boss, the police, your mother-in-law, and they will all ask for the recipe.
