Authentic Florida Key Lime Pie is just 3 ingredients
Poured into a pie shell with whipped cream icing
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!
*not sponsored by any of these companies
-
- Cornstarch
-
- Key Lime Juice
-
- Vegan Butter
-
- Vegan Condensed Milk
Don’t worry I have an alternative recipe below for Non ~ Condensed milk version for the filling 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:
Be sure to have your crusts prepared ahead of time though because this is one fast recipe!
I am using 4.75″ tart molds with removable bottoms
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!
This is from a heavy measure of cornstarch when using volume measuring spoon vs the 100% accurate scale measure in grams.
Canned ~vegan~ Sweetened Condensed Milk is the absolute key to success in this recipe
However I know this may be a difficult ingredient to get
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

This. Was. Amazing.
I made 6 individual tarts for a dinner with friends. They all loved it, and the whole “vegan thing” was very well received! (They’re good people, and always love what I make).
Two things to note:
1. I misread the “two cups” as “two cans” of condensed coconut milk. And my two cans were 11 ounces each. My bad, but it was still good!
2. This tarts pack a seriously citrus/tart wallop UNLESS you also make the whipped topping. You know how sometimes you can forgo the topping to a custardy tart? You…shouldn’t do that with this one. BUT – the combo of the two things is phen-om-in-al!!!!
Highly recommend this dessert. Oh, and Silk Heavy Whipping Cream Alternative for the win!
awesome! thank you for the feedback! I am so glad it still worked out with the 2 cans!
Hi,
I want to make this recipe but the comment from the woman who said she accidentally used 2 cans instead of 2 cups made me look twice. Right now your recipe DOES say 2 – 11 oz cans of Sweetened Condensed Milk, which is correct?
Thanks!
Yes it is correct as written
Fantastic! I’m doing that thing I hate in comments – I haven’t made the recipe yet 🙃 but am commenting! I have always had success with every one of your recipes I have made so I know this will be great. I have a couple of key lime trees in my yard and I can get the condensed milk at Walmart-I’m ready to go ! BTW, totally agree about weighing ingredients. Thanks for all your great recipes and wonderful videos. 😊
LOL! Thanks for the comment, let me know how it goes!
Made this the other night and OMG!!! So good!!!! I did add a tiny bit more lime for an extra bite. Pairs well with vegan whipped cream!!! OMG!! I also used Bischoff cookies for the base. Can’t wait to make it again!!
Forgot to give it 5 stars
THANK YOU!
Hoping to make this for a mixed group of vegans and non in a bar format. Would this recipe work in a 9×13 or would you scale up?
I would probably 3X the recipe! 9″ x 13″ is quite a large pan!
Be sure to have the parchment paper flapping over in excess so you can get the entire bar out easily for cutting into portions (unless you plan to serve them direct from the pan?)
Thank you – I’ll give it a shot and let you know how it goes! Happy to have discovered your site as vegan baking is new to me, and there are lots of things here that look great for sharing.
Hi Gretchen! So just to confirm, the crust doesn’t require any baking, you just freeze it?
Super excited to try this! Thank you!
That’s correct! Some people like to bake the crust for like 10 minutes, it will help with it’s integrity upon storage (meaning it will be less likely to crumble and break apart after a day or too like the un-baked one has a tendency to do!) But in the interest of making this a NO BAKE dessert, I don’t often bake the crust
Hi there, so in the condensed milk version are you using the full two cans? That part seems a little confusing. Thanks!
Hi! Yes it is 2 cans total (the cans are the small cans ~ 11ox each)
This was super delicious! Only thing is that I followed the recipe exactly and used a 9” pie crust but still somehow had about 300ml that wouldn’t fit in the crust. Oh well, more leftovers for me!
Hmm thank you for letting me know! I will note that! But I’m glad to know you liked it!
