This recipe took four years to develop. During that time there were many truly awful key lime pies. There were the ones that never set and remained a fluid in a soggy crust. There were the ones made with tapioca which had a consistency somewhere between gelatin and rubber. There were the ones that were too dry and the ones that looked good until you cut them. There were those that were powerfully lime flavored and those that tasted like rubber.

And then after giving up for almost a year I developed a lemon pie recipe which gave me the idea for this one, and finally, finally it worked and it is easy. It has only seven ingredients.

A few things to note

1) Key lime pie requires key limes which are tiny and unbelievably sour. You can get them by the bag at stores like Whole Foods. If you cannot find key limes you can use the zest from regular limes and key lime juice (there is a company called Nellie and Joe’s that sells key lime juice.

2) I used canned coconut cream from Trader Joe’s. Coconut Milk will not work. The recipe needs the fat in coconut cream.

3) The pie tends to crack like a cheesecake does. I solve this problem with a non-dairy whipped cream.

4) It cannot be made egg free, or coconut free but it is free of all other tree nuts, and of course it is gluten-free, dairy-free, soy-free, corn-free and peanut-free. It uses no gums or stabilizers.

Ingredients
1 1/2 teaspoons freshly grated key lime rind
1/3 cup key lime juice
3/4 cup granulated sugar
1 can coconut cream (I used Trader Joe’s…do not use coconut milk)
4 large whole eggs
1/8 tsp salt
Gingersnap or graham cracker crust (separate recipe)

Equipment
Whisk or electric mixer
large bowl for mixing filling
measuring cups and spoons
Spatula
Rasp or grater for lime peel
Ten inch pie pan (preferably ceramic)

Instructions
Make sure that the graham cracker or gingersnap crust is baked and cooled.
Mix eggs and sugar in mixer until combined. Do not whip or overbeat. You just want the eggs truly incorporated
Add coconut cream, salt, and key lime zest.
Add the lime juice and combine thourougly but without whipping.
Pour mixture into baked and cooled crust
Bake at 350 for 45 minutes to an hour or until wiggly but no longer liquid and somewhat set when shaken.
Chill for at least 8 hours. Slice and serve.

Note that this keeps for a week in the refrigerator…it may last longer but we always eat it all by then.

    I made this for my husband for his birthday and his comment was’ “You’ve outdone yourself!” It really was soooo delicious. So thanks for a YUMMY recipe and for making me look good! :)

    Hey, I found your recipe and was so excited! I have a friend who’s allergic to gluten, soy, and lactose. However, she also cannot have sugar or artificial sweeteners (not even fruits that naturally have sugar like apples) can you think of a way I could sweeten this pie? Maybe if I used regular limes? Or do you know another pie that fits that bill?

      I don’t think this pie would work without sweetener or the acid in the lime juice. the crust alone is pretty sugar laden. I do however think that the custard could possibly be adapted to just use eggs and coconut cream…maybe with a little vanilla as more of a flan. You might be able to make a coconut crust using shredded coconut and coconut oil that would also work. It would be more of a coconut custard pie. I would have to test it out. In theory it should work, but right now I have a pumpkin bread in my fridge that worked in theory….and only in theory. in practice its kind of inedible.

    I tried this today and it never firmed up, which was so odd! I thought with all those eggs there was no way to fail. I baked it for an hour and ten minutes. Burnt around the edges and liquid, separated pools in the middle. It seemed like what happens when an aioli or mayo breaks and separates.

    • christina says:

      Wow. I am so sorry that happened to you. I am planning to make this pie again soon and I will recheck the instructions to see if I left something out. The only thing I can think of is coconut milk vs coconut cream. The stuff I use is coconut cream from a can and its pretty thick and stiff at room temperature. Trader Joe’s has a coconut cream and its also sold in an organic version in tiny green cans at whole foods.

    Thank you for this delicious recipe!

    A couple of things I did different was instead of 4 eggs, I used 2 eggs & 4 egg yolks – to help with the setting of the custard – this way I avoided the custard cracking.

    I used those extra egg whites to make my own base using shredded coconut, hazelnut meal, a table spoon of rice flour, 2 table spoons of sugar & tbspn of margarine. Blind baked, then poured the custard on top.

    Amazing tasting, creamy, slap bang zesty flavor! Can’t recommend this recipe highly enough!

      I love the idea with the yolks and the crust. Your way, if I swap in coconut flour for the rice flour would even make it fully and easily kosher for Passover. I am going to try it that way next time. Thanks for the tip!
