Authentic Florida Key Lime Pie is just 3 ingredients
But to mimic the authenticity of the original I had to do some science-y sleuthing!
In my search for the best vegan Key Lime Pie recipe
I discovered that most recipes included things like vegan cream cheese or tofu
And I just didn’t want to introduce those foreign ingredients into one of the simplest recipes out there!
So my version is just four basic ingredients that should be fairly easy to find!
NO TOFU! NO NUTS! NO CREAM CHEESE!
Don’t worry I have an alternative recipe below for Non ~ Condensed milk version as well as a homemade vegan condensed milk recipe
Now Let’s Talk About the Texture!
Vegan custard can be difficult to master since the texture will border on “rubbery” *see notes below about measuring cornstarch
A traditional Key Lime Pie has a very unique texture due to the egg yolks in the recipe
To mimic that texture I was careful about how much thickener to use in my recipe below
*see more notes below about Sweetened Condensed Milk in this recipe

NOTES FOR SUCCESS:
I am using 4.75″ tart molds with removable bottoms
Be sure to have your crusts prepared ahead of time though because this is one fast recipe!
However you can easily adapt this entire recipe to make an 8″ pie instead
Cornstarch is a very difficult ingredient to measure consistently with a volume spoons measure
So while I list both measures below I cannot stress enough how the grams measure with a scale is going to give you the best results.
Many times people have complained that their custard is like rubber and they don’t know why!
Canned ~vegan~ Sweetened Condensed Milk is the absolute key to success in this recipe
Although I know this may be a difficult ingredient to get, so if that is true for you it is quite simple to make your own!
By simmering coconut or soy milk with some sugar until it is thick like the canned version
But wait! I also have a No~ Condensed Milk version for you too! *recipe below
First of all though, I will say I prefer the sweetened condensed milk version much much more
The texture that is achieved from this ingredients is the closest to the original key lime pie recipe that I remember, resulting in a thick, gooey filling
I am using Nellie & Joe’s Key Lime Juice *not sponsored but fresh squeezed key lime juice works great too!
For the vegan whipped cream I am using Silk brand heavy whipping cream * not sponsored
But if you cannot get this or do not want to buy it I have several homemade vegan whipped cream options for you here on my website
Or, add a ripe avocado to about 1/3 of the can of coconut milk (liquid included) + ½ cup confectioners sugar and then just whiz it all up in a high speed blender or magic bullet
Instant avocado whipped cream that is the perfect compliment to this Key Lime Pie
