Creamy dreamy vegan key lime pie! This deliciously lime flavored pie has a perfect mousse texture and is wonderfully sweet and tart at the same time.
I’ve been wanting to make a vegan key lime pie forever. The thing that was holding me back? I didn’t know what kind of key lime pie I wanted to make.
Was I going to do something like avocado and key lime juice for a lovely raw vegan version? Was I going to do a baked version? Something in-between?
In the end it was looking at what the ‘regular’ version of key lime pie actually is that was the deciding factor.
A regular non-vegan key lime pie uses condensed milk, key lime juice and zest and egg yolks for the filling.
So I decided to just do an adaptation of the ‘original’.
And by the way if you love key lime flavor then check out our key lime cake and key lime cupcakes too!
How To Make Vegan Key Lime Pie
For our vegan version we used a vegan condensed milk, whipped coconut cream and lime juice and zest.
The crust can either be made with vegan graham crackers or vegan digestive biscuits, it depends where you are in the world as to what would be easier to get. And if you can’t get either of those then use any vegan cookie you like.
I baked the crust, just for 10 minutes at 350°F. I wanted to make the crust very firm and baking it is a good way to ensure that it is! You don’t have to bake it though, if you’re happy with a slightly more crumbly texture to the crust then you can skip that step.
The main trick to getting this vegan key lime pie perfect is to make sure your whipped coconut cream is very very firm when whipped. If it is not, then add in 1/4 – 1/2 tsp of xantham gum to get it nice and firm.
You also want to let your vegan condensed milk cool in the fridge after making it so that it gets nice and thick. If you’re using a store-bought variety of vegan condensed milk then this won’t apply, but if you’re making your own, let it cool and thicken in the fridge first.
And then you have to make sure that the pie has enough time to set properly before you slice and enjoy!
It is supposed to be nice and firm, with a mousse-like texture but still, pretty firm! It is supposed to hold up nicely when you slice it. If it’s not doing that then let it set for longer. You can speed things up by putting it in the freezer, just don’t forget it in there, or you’ll need to have patience again while it thaws.
Lime Extract
For extra key lime flavor you can use some lime extract but I have also tried this without lime extract and the flavor is still amazing, so that’s an optional extra.
Key Limes vs Regular Limes
And then when it comes to key limes vs limes, you can use either/or. So whatever is easiest to get hold of, it won’t make a significant difference to your end result. To be more ‘traditional’ use key limes, but really no worries at all if you use regular limes.
You will love this vegan key lime pie! It is:
- Creamy
- Mousse textured
- Deliciously lime flavored
- Super easy to make
- Both perfectly sweet and tart!
Keep it covered in the coldest part of your fridge and enjoy within a few days. It is also freezer friendly, just let it thaw in the fridge when you’re ready for it.

Creamy dreamy vegan key lime pie! This deliciously lime flavored pie has a perfect mousse texture and is wonderfully sweet and tart at the same time.
Ingredients
For the Crust:
- 10.5oz (300g) Vegan Digestive Biscuits or Vegan Graham Crackers*
- 1/2 cup (112g) Vegan Butter (Melted)
For the Filling:
- 1 and 1/2 cups (360ml) Vegan Condensed Milk*
- 1/2 cup (120ml) Key Lime Juice (freshly squeezed)*
- 1/2 tsp Lime Extract*
- 2 Tbsp Lime Zest
- 2 14oz (400ml) Cans Coconut Cream (Chilled Overnight)
- 1/4 – 1/2 tsp Xantham Gum (if needed)
For Decorating:
- Lime Zest
Instructions
- Spray a 9 inch round pie dish with non-stick spray and set aside. Preheat the oven to 350°F (180°C).
- Add the vegan digestives or graham crackers to the food processor and process into crumbles. Melt the vegan butter and mix in with the cookie crumbles and then place into the prepared pie dish and pat down firmly. Use the bottom of a measuring cup to press down firmly along the bottom and work the crust up along the sides.
- Place the pie base into the oven and bake for 10 minutes. Remove from the oven and leave to cool.
- Prepare your vegan condensed milk as per the linked recipe. Pour this out into a bowl and place into the fridge to cool and thicken.
- Remove the cans of chilled coconut cream from the fridge being careful not to shake them around. Open the cans and scoop out only the hardened cream section that will have risen to the top into the bowl of a stand mixer, leaving the watery part behind. Starting at slow speed gradually increase speed until the cream is whipped. For best results in this recipe, you need the cream to be very firm and well whipped with stiff peaks. If yours is a bit on the softer side, add in a 1/4 – 1/2 tsp of xantham gum and whip again. It will thicken fast.
- Squeeze the lime juice and grate the lime zest.
- Add the lime juice, lime extract and 2 Tbsp lime zest to the bowl with the condensed milk and whisk with a hand whisk to combine. Then fold in the whipped coconut cream.
- Pour this over the cooled crust and place into the fridge for a few hours to set. If you want to speed it up a bit then you can put it into the freezer, just don’t forget it in there or you’ll have to wait for it to thaw!
- Decorate with lime zest and serve.
Notes
*This is approximately 26 Digestives or 20 Graham Cracker Sheets. It would be most accurate to go by weight since different brands have different size cookies.
*This is one full batch of homemade vegan condensed milk. Make it using soy milk or rice milk powder so that it’s nice and thick for using in this pie. You can also use store-bought canned vegan condensed milk, and if so, you can use a full 14oz/400ml can.
*Use regular limes if you can’t find key limes.
*You can omit the lime extract if you don’t have it/can’t find it. This pie is still delicious without it.
*The filling for this pie is gluten-free, so if you wanted to make the whole pie gluten-free you could switch for a gluten-free cookie for the crust.

Is there any way to incorporate Avacado into this pie? I would love to for the health benefits as this is one of my favorite deserts!
I think you could! It’s not something I’ve tried but I think it could work. 🙂
A question about the coconut cream: Do you mean the cans actually labeled as “coconut cream”? If so are you using the sweetened or non-sweetened version. If not, are you referring to taking regular cans of full fat coconut milk, putting that in the fridge and removing the hardened cream?
Hi Kristen, it’s cans of coconut cream, unsweetened.
Hi Alison!
I’ve made regular key lime pie for every familiy member so far except for my parents, mainly because my mother has to avoid sugar, and I could never enjoy it with them because of a milk allergy. I found your recipe last week and I was thrilled to see that there was a sugar- and milk-free alternative to both the pie and to sweetened condensed milk!
I only had two minor challenges – I couldn’t find sugar-free soy milk powder in-store here in South Africa and one of my two cans of coconut cream didn’t separate! So I made the condensed milk the classic way – simmering milk (coconut milk) and sugar (stevia) together for what seemed like an eternity. It didn’t come out as thick as I imagined your condensed milk to be, even after it stood in the fridge overnight. And then my fix for the coconut cream was, I whipped the one can that did separate, kept it to one side, then whipped the un-separated one with the xantam gum. It gave it a very gelatinous texture, but it mixed surprisingly well with the thoroughly-whipped coconut cream from the first can. I think the xantam gum helped keep the pie together after my condensed milk didn’t thicken enough. All-in-all it was a fairly easy pie to make and I learned a lot from making it.
The pie ended up being very light and very rich. My husband still prefers the regular version (with store-bought sweetened condensed milk) only because it’s got a fuller texture, but everyone loved it: So much so that my mother wanted the recipe! This is by far my favourite key lime pie xx
So glad it worked out well! Thanks for sharing. 🙂
Hi! I don’t have canned coconut cream in our village shop but here in Finland we have many brands of oat cream that produces a nice thick whip and I would love to try that. Can you estimate how much I should use that? I have no idea how much of the thick white stuff is in those coconut cream cans…thanks😁!
Hi Sanna, it would equal two cups of cream, you usually get at least a cup of cream from each chilled can of coconut cream. All the best! 🙂
I made this pie and it was delicious, however, it came with some challenges. I was not able to find canned coconut creme locally. The closest I could come up with was the coconut cream used to make pina coladas, which is available in liquor stores. It is very smooth and creamy, and comes in a large squeeze bottle. It absolutely does not whip, even though I tried with my KitchenAid mixer.
I made the recommended vegan condensed milk per the recipe. I purchased powdered soy milk online, and followed the recipe exactly. It made a large amount, and I believe it did say to use the whole recipe, which I did. It was very thick and gelatinous. Per the recipe, I added additional hot water, a LOT of additional water, almost a whole cup extra. It got even more thick while sitting out. I used a hand blender to make it creamy before combining with the coconut cream. (which had not whipped up at all)
I wanted the taste of Key Limes, so I used bottled Key Lime juice. I also added the lime extract. I used regular limes for the zest.
I did use 1/2 teaspoon of xanthan gum as I was fearful the mixture would not set up. I also added a small amount of green food coloring to give it a little bit more color.
I put the pie in the refrigerator, not the freezer. I was confused about this, as it did not seem to be a freezer pie recipe from the article, yet the actual recipe says to put it into the freezer.
The good news is that the pie DID set up after several hours in the fridge (about 6). It was delicious! I made it for my daughter, a vegan, and she was delighted. Before she was vegan, she used to love to make Key Lime pie. She had tried a Key Lime pie using avocado, and had one good experience and one bad. This pie was so pretty, and very tasty, everyone loved it, even the non-vegans!
I will try this recipe again when I can find coconut cream in a can, and also canned condensed milk.
Thank you for your hard work developing this treat!

Hi Sally, sorry to hear about the challenges in making this pie but I’m thrilled that it turned out well in the end and everyone enjoyed it! 🙂 Thanks for sharing and the feedback! 🙂
Hi made this but it seems that the condensed milk/ lime juice split when I added the whipped coconut cream. Any ideas ? Thanks
Oh no! Sorry to hear that happened. I haven’t had that happen before. The lime juice needs to be very well mixed in with the condensed milk and then the whipped coconut cream has to be very carefully folded in. If you did that then I’m not sure why it split!
This is fantastic 🙂 🙂 🙂
★★★★★
This looks amazing, I gave it a go and the taste was perfect but for some reason it wouldn’t set, I don’t know why but it tasted so good 🙂
Hi Holly, what a pity it didn’t want to set, did you put it in the freezer? So glad it tasted good though! 🙂
Being gluten free, it’s not easy to get delicious treats but this is such a fantastic lime pie!
★★★★★
Yes, as long as you use gluten-free cookies for the crust this can be a delicious gf dessert. 🙂
Hi! That sounds amazing & I will definitely make it as my non-vegan mum loves key lime pie! Is cream of tartar a substitute for the xantham gum? Thanks for your reply!
Hi Tina, no cream of tartar is something different altogether. You may not necessarily need the xantham gum, if you have a good brand of coconut cream that you use for whipping. 🙂
What can I use instead of lime extract? I don’t think we get that in South Africa
Sorry… just saw in your tips section that I can omit the lime extract
Hi Abigail, yes, it’s a nice addition to the flavor but not crucial. 🙂
