Why you’ll love this key lime pie
After our visit to Key West last year, I was determined to make dairy free version, but it proved to be more difficult than I thought. Just like the dairy free cheesecake, baking didn’t seem to be the right choice, and I didn’t want to rely on nuts to firm it up.
Thanks to my dairy free eggnog recipe, I realized the thickening power of eggs, and decided to try a stovetop custard-based filling for the key lime pie and it worked like a dream.
It still needs to be chilled, and the condensed coconut milk can take forever to firm up after being heated, but it works. The richness of the egg provides a creaminess that really balances the sweet, tartness of the key limes, and it makes for a beautiful pie.
We served ours with coconut Reddi-wip, but you could make homemade coconut whipped cream or even vegan whipped topping like Tru-whip. If you’re feeling ambitious, you could even use the meringue topping from my baked Alaska cupcakes to make this into a key lime meringue pie instead.This is where you talk about the recipe, something related to the recipe.

Ingredient notes:
- Condensed coconut milk – You can find this in the organic section of your grocery store. If it’s not there, check the regular baking aisle and look by the regular condensed milks. If not, it’s always available online.
- Key limes – Yes, you can definitely substitute regular lime juice for key lime juice. I almost always do. It’s hard to find key limes here and they’re a big pain to juice since they’re so small. You could buy bottled key lime juice, which is really great, but I honestly think fresh lime juice is better than bottled key lime.
Making changes to a recipe can result in recipe failure. Any substitutions listed below are simple changes that I believe will work in this recipe, but results are not guaranteed.
Frequently asked questions
You really cannot keep this pie out of the fridge long without it starting to melt. I would recommend serving immediately after removing from the fridge. Return what is not being served to the fridge right away to help it keep its shape.
This pie should keep in the fridge well for about 2-3 days. You can freeze it for up to 2 months as long as it’s wrapped tightly to prevent freezer burn.
Even though you may assume this pie should turn out with a pretty green color, key lime pie should be a yellow color. The yellow color of the key lime pie actually comes from the egg yolks used for the filling.

Dairy Free Key Lime Pie
Ingredients
- 1 extra large pie crust, (store-bought)
- 1 1/2 cup key lime juice, divided
- 2 11-ounce cans sweetened condensed coconut milk
- 4 tablespoons cornstarch, (1/4 cup)
- 8 large egg yolks
- 1/4 teaspoon coarse salt
- dairy free whipped cream, such as Reddi-wip
Instructions
- Make or buy your crust. Our you can just buy a pre-made one at the store. Just make sure you get one of the extra large ones. They should say they hold "2 extra servings" on the label.
- Heat the liquid. In a saucepan, heat the condensed coconut milk and 1 cup of the lime juice to a simmer. The coconut milk should go from being nice and thick to being runny and thin.Whisk the remaining lime juice with the cornstarch in a small mixing bowl. Set aside for later.
- Temper the eggs. In a large bowl, whisk the egg yolks and salt until smooth. Then, ladle 1/2 cup of the warm liquid into the eggs, whisking continuously to prevent curdling or scrambling of the eggs. Do this two times, and then transfer the mixture back to the saucepan, whisking until smooth.
- Cook the filling. Add the cornstarch mixture to the pot with the egg yolks and continue whisking until the sauce has thickened and the mixture reaches 160˚F. If you don't have a candy thermometer, you can tell it's done with it easily coats the back of a spoon.
- Chill your pie. Pour the filling into your prepared pie crust and allow it to chill on the counter and come to room temperature for about 1 hour, then transfer to the refrigerator for at least 6 hours.You can also put it in the freezer to speed the process up. If you choose to freeze, you will want to remove your pie from the freezer for about 20 minutes before attempting to slice and serve it.

The filling tastes so good! I am having a problem getting it to set up though. I kept it in the fridge overnight and it was super runny. Any suggestions? Thanks!
There’s a chance that you didn’t cook the eggs enough for them to set up and thicken into a custard. Did you use a thermometer and cook to 160˚F?
Ingredients include salt. Instructions – no salt?
You’re totally right. Sorry about that! It honestly doesn’t matter when you add it. It’s just to balance the sweetness and enhance flavors.
Made this yesterday, and it was absolutely delicious! I made my own crust wuth crushed Biscoff cookies, and added a little key lime zest. One of the best dairy free desserts I’ve tried!
The recipe lists salt but don’t say when to add
You’re right! I will have to fix that. It actually doesn’t matter when you add the salt, it’s just included to balance the sweetness. I typically add it with the eggs.
The ingredients list includes dairy free whipped cream but the steps never mention it. Is that just a topping, not part of the filling?
