While doing some research for this recipe, I learned so much about key lime pie a la the one and only Martha Stewart. For instance, I discovered where key lime pies originated, what true key limes look and taste like, how sailors used to suck on limes to fend off scurvy, and how to store key limes for year-round use.
Oh, Martha? Is there anything you DON’T know? #teachmeyourways
Origins of Key Lime Pie
The exact origin of key lime pie and how it should be made are hotly debated topics. And we don’t claim to be experts. But from what we’ve read, there are several theories on its origin:
- Key West, Florida
- The Borden Milk company in New York
- Aunt Sally who cooked for a Florida millionaire
- Fishermen in the Florida Keys
The following recipe is our inspired, plant-based version of this creamy, tart pie.
Vegan Lime Pies
The thing is, I couldn’t find key limes anywhere in Kansas City! (BOOOO). So I subbed regular limes and you can, too. The only remaining ingredients are:
- cashews
- agave nectar
- coconut milk + oil
- graham crackers
- vegan butter
That’s it! This is 7-ingredient vegan dessert perfection. And to keep it gluten free, simply sub gluten free cookies OR use a walnut-date crust, such as the one I used for my Simple Vegan Cheesecakes. Next time, I think I’ll go that route to mix things up (plus, it really can’t be beat).
The only real pre-prep you have to do is soak cashews for 4 hours or overnight. The rest takes place in the food processor and blender, starting with the crust.
The crust is simply 1 sleeve of graham crackers and 1/4 cup melted vegan butter (I use Earth Balance).
Simply pulse the two together in a food processor and then press into muffin liners (or make a large pie and use a glass pie dish). Then use a small glass or the back of a spoon to press down and get a uniform top. Lastly, bake for 10 minutes to brown.
Once you blend your filling until creamy and smooth it’s onto the crust and then into freezer. These don’t take but a couple hours to set up so the wrappers peel away easily for serving.
Oh man, these turned out so good and have me aching for spring. They’re:
Creamy
Tart
Sweet
Cold
Satisfying
Slightly crisp from the graham cracker crust
& A perfect light dessert
You can either eat these straight from the freezer, or let them set out for 10-15 minutes to soften, which I preferred. Then they taste like true key lime pie! You’d never guess they were dairy- and egg-free. Enjoy!
7-Ingredient Vegan Key Lime Pies
Ingredients
Crust:
- 1 1/4 cups vegan graham cracker crumbs (about 1 sleeve graham crackers as original recipe is written / GF for gluten-free eaters)*
- 1/4 cup (4 Tbsp) vegan butter (melted // such as Earth Balance)
Filling:
- 1 cup raw cashews (soaked for 4-6 hours or overnight, then drained)
- 3/4 cup light or full-fat coconut milk (well shaken)
- 1/4 cup coconut oil (melted)
- 3-4 large limes* juiced (3-4 limes yield ~1/2 cup juice)
- 1 Tbsp lime zest
- 1/3 – 1/2 cup agave nectar (depending on preferred sweetness)
Instructions
- Preheat oven to 375 degrees F (190 C) and line a standard muffin tin with 12 paper liners (as original recipe is written // adjust if altering batch size).
- Add graham crackers to a food processor and process until you achieve a fine meal. Then add melted butter and pulse to combine.
- Distribute evenly among muffin tins and press down with a glass or spoon to flatten. Bake for 10 minutes or until golden brown. Remove and set aside to cool.
- Add all filling ingredients to a blender and blend on high (or liquefy) until creamy and smooth. Taste and adjust flavor as needed, adding more lime zest/juice for more tart, or more agave for added sweetness.
- Pour filling into muffin tins and tap on counter to release air bubbles. Top with a bit more lime zest and loosely cover.
- Freeze for 2-4 hours or until firm. Remove from the freezer for 10-15 minutes to thaw before serving. Will keep covered in the freezer for up to 2 weeks, though best when fresh.
Notes
*Loosely adapted from Martha Stewart
*To keep this recipe gluten-free/grain-free, simply sub gluten-free cookies in place of the graham crackers OR use a walnut-date crust.

Sara L says
My daughter and I made the pie. We made a full pie instead of mini pies. It set up fine and had perfect texture. It was quite literally the worst tasting thing I have ever made. It tasted like absolute vomit.
Oh no!! We’re so sorry it wasn’t tasty, Sara. Is it possible one of your ingredients was spoiled? We ask because this is usually a reader favorite!
Sarah D says
Fyi this usually happens when you use old limes. I accidently used spoiled ones for a traditional key lime pie and the whole thing was ruined. You don’t know if they have gone bad by just looking at it. You would have to taste it.
Nuts can also go rancid and taste very bad. You likely used bad cashews or bad limes.
A Y says
Can you replace the vegan butter in the crust with coconut oil?
Yes, that should work well!
Ingrid says
I made this as a pie, I used lemon strawberry Joe Joes for the crust and monkfruit maple syrup for the sweetener. Absolutely amazing!!!! Thank you!
That sounds like such a fun twist! Thank you for sharing, Ingrid! xo
April says
You are a culinary genius. I have made many of your recipes. This one I made with the walnut date crust and maple syrup. They are in the freezer chilling so I haven’t tried in it’s entirety yet, however the filling is absolutely delicious and I can not wait to have these later!!! Thank you!!!
Aw, thank you so much for your kind words and lovely review, April! xoxo
Laura says
These are sooooo good!
I want to make them for my partners family however one of them is allergic to cashews (no other nuts, just cashews). Is there anything you could recommend i can substitute the cashews for? Thanks! X
We’re so glad you enjoy the recipe, Laura! We haven’t tested without cashews and can’t guarantee results, but other readers have had success using half of a package of silken tofu. Raw, unsalted sunflower seeds might also work. And another option might be macadamia nuts, but they don’t get as creamy. Hope this helps!
kass says
I’m looking for a key lime filling to go inside chocolate truffles – would this filling work well do you think? Will be serving at room temp.
Hmm, we don’t think that would work, but maybe!
Caitlin says
Would it be possible to use mini muffin tins and make little ones? I’m assuming that would make about 24, if this recipe makes 12?
Yes, we think so!
Natalie says
This is a fantastic recipe. I’ve been looking for healthier desserts and this was a huge hit for me and the hubby. He couldn’t believe it was vegan. He noticed the “cheesecake” flavor was a bit different but in a positive way. With the smooth texture and crumbly crust (and a dollop of vegan whip), it 100% hits the target.
Plus, they hold up great in the freezer. Will definitely make these again! Thanks!
Yay! We’re so glad you both enjoyed them, Natalie. Thank you for sharing! xo
Ciara says
Would this work in a spring form pan as one big cheesecake?
Hi Ciara, other readers have reported it works!
andrea says
just wanted to let you know that agave nectar is virtually the same as high fructose corn syrup bc of the heavy chemical processing! Agave is not inherently sweet.
Hi Andrea, We think maple syrup would also work in this recipe! This is an older recipe from when we used to use agave more.
Sany says
Amazing recipe! Can’t wait to try now for thanksgiving. Can I use maple syrup instead of agave nectar?
Hi Sany, yes, maple syrup should work! Enjoy :)
Lillian says
This has become a family favorite in the past few years! Made them for the first time two years ago (along with a traditional key lime pie) since half the family is either dairy free or vegan but now we’ve ditched the normal pie entirely. It’s one of those recipes that isn’t just “good for a vegan version”, it’s just plain good! The frozen creamy texture enhances the refreshing sourness of the limes making them a perfect summer treat. And if you’re one of those people who can always taste coconut when it’s used (like me), this is a rare case where it combines well with the main flavor instead of overwhelming it. It’s also a criminally easy recipe, the hardest part is remembering to soak the cashews!
We’re so glad you enjoy this recipe, Lillian! Thanks so much for sharing! xo
Taylor Vettese says
I’ve made these so many times and here I am making them again to impress family for Canadian thanksgiving! Also going to make your amazing apple crisp and pumpkin pie if I have time. I tell everyone all my recipes are always minimalist baker!!
Aw, thanks so much, Taylor! We’re so happy you enjoy our recipes. Hope you had a great Thanksgiving! xoxo
Gary says
Wonderful and super easy recipe. This is my go to for my fiancé since she has stomach issues. I tend to add a little more coconut milk and lime for a slightly larger batch and adjust the agave as needed. No cashews and use walnuts instead. But adding more coconut milk and lime definitely requires it to be more on the frozen side, otherwise it’s runny if left out. But we like it more frozen as then it’s kind of like an elevated lime popsicle. :)
When I make recipes, I generally try them as they are first and then adjust to what I’m doing or what I want it to taste like when I do make it again. Great recipe as is!
Thank you for sharing, Gary! We’re so glad you enjoyed them!
Eve-Marie says
If I travel for three to four hours with these in a cooler, and then re-freeze when I get there, will they be ok?
Thanks!
Hi Eve-Marie, that should work! At room temperature they would get soft, but with a cooler and re-freezing they should be fine. Hope you love them!
V says
Hi there! Can you recommend a vegan graham cracker??
Yes! The Nabisco (classic) or our homemade recipe.
Crystal says
This was AMAZING!
I made a few alterations that made it that much more delicious!
* I substituted the coconut oil for vegan butter
* I added 1/4-1/3 cup of vegan cashew cream cheese
*I added a cap full of vegan Vanilla extract
I forgot the Key lime zest but to be honest, it was just full of flavor! Thank you for this recipe. Next time I will make them in the cupcake tins, I made a 8×8 casserole dish 🤤
Amazing! Thanks so much for sharing, Crystal! xo
Erika says
This recipe looks delicious. I need to make a full pie (aka birthday cake). Will the 12 muffin portions translate to one 8-9″ pie? Thanks!
Hi Erika, yes! As written the recipe should make enough for an 8-9 inch pie pan. Enjoy!
Erika says
Ah, thank you! I missed that. I made the pie and it’s SO delicious.
Yay! We’re so glad to hear it, Erika! xo
Wendy says
Absolutely delicious! And so easy to make.
Everybody loved them! To get them out of the muffin tin, I put warm water on a sheet pan, placed the muffin tin on it and almost immediately I was able to separate them from the tin. Super simple. Place the tarts out for ~15-20 minutes and they are perfection. Light, creamy and refreshing. Thanks for the excellent recipe:)
That’s a great hack, Wendy! Thank you so much for the lovely review and for sharing your tips! xo
Julie says
Excellent recipe. Love making this in the summer. Made is gluten free with partake graham crackers and it turned out perfectly. Everyone commented on the deliciousness of the crust.
A trick I’ve found to this recipe: if your blender is a bit weaker like mine and takes some time to liquefy the cashews – add all filling ingredients besides lime juice and melted coconut oil to blender until nuts are perfectly liquefied. Then add key lime juice and melted coconut and blend for a final 30 seconds, tasting and adjusting for flavor. Overblending with the lime juice will turn your plant milk into buttermilk!
Perfect recipe. My family told me I should open a bakery. Thank you ❤️
Awww, that’s AMAZING! Thank you so much for the lovely review and helpful tip, Julie! xoxo
Dale says
I recently had to multiply this recipe x6 for a women’s church event. It was my first time making them and so many people approached me afterwards for the recipe.
I think next time I would use bottled lime juice as it took me quite a while to zest and squeeze almost
six pounds of small limes in order to have enough juice.
I know I can never go wrong with your recipes.
Whew, that sounds like quite the workout! Thanks so much for the wonderful review, Dale. We’re so glad everyone enjoyed!
Ariel says
Can I make this with cashew butter or cashew milk instead of the raw cashews soaked? Thanks!
Hi Ariel, the cashews give the key lime pies structure! We wouldn’t suggest using cashew milk or cashew butter to replace them!
Nancy Reyner says
Hi! I just made this recipe but had a couple of issues getting them out of the muffin tins. I did everything in your recipe, except substituted maple syrup for the agave. I left them in the freezer still in the metal muffin tin, with the paper liners in them, for the 2 hours. When I took them out of the freezer they wouldn’t come out of the muffin tins. So I let them warm up a bit but then they got too mushy to remove and hold their shape, and also the paper liners kept tearing apart. I’m thinking next time I won’t fill the tins so full, so I can get a better grip on them. Is there a better way to remove the pies from the muffin tin, with the paper still on, while they are still frozen? Maybe I need to use stronger paper liners? Even with all the hassle they tasted absolutely great!
Hi Nancy, thank you for sharing your experience! We’d suggest trying a different brand of parchment paper to see if that helps!
Natalie Duncan says
I can’t believe I’m just now getting around to reviewing this because i make it every year since I tried it. This is a St. Patricks Day tradition in my household. SOOO GOOD!
Whoop! We’re so glad you’re enjoying them, Natalie. Thank you for sharing! xo
Iris says
It melted so quickly :(
Hi Iris! These are like ice cream and will melt at room temperature if left for too long!
Sa says
Amazing! I never even liked Key Lime Pie before I spotted this recipe.
The substitute that worked wonderfully IN REPLACEMENT OF AGAVE SYRUP (I am not a fan:)
1/2 block Violife brand cream “cheese”
+
1/2 (32 OZ.) Bag of 10x Powdered sugar
I doubled the recipe and it filled (2) 8 inch pie pans pans. I used plant butter instead of oil.
Also the more zest the better!
Enjoy!!!
We’re so glad you enjoyed it, Sa! Thanks so much for sharing! xo
Marcia says
What do you recommend as a substitution for agave syrup?I.e., would maple syrup work or is there something else that might work better? Thank you for your wonderful recipes and cooking/baking advice and help. I’ve learned so much from you.
Hi Marcia, we haven’t tried this recipe with maple syrup, but other readers have had success with it! Thanks so much for the kind words and support! xo
Sa says
Non-syrup option: If you go by the standard recipe;
1/4 package of Violife cream cheese + ~1/2 a (16 oz.) bag of 10x powdered sugar.
I doubled it when I made mine and it worked great! Really is an amazing recipe. My non-vegan partner loved it and this is one of his favorite pies!
JHA says
What can be substituted for the cashews? Tofu vegan cream cheese? do you have any suggestions?
Hi! We haven’t tested this without cashews and can’t guarantee results, but other readers have had success using half of a package of silken tofu. Hope this helps!
Ashley says
These are delicious! I tasted the mixture in the blender and wasn’t super excited, the lime flavor was not strong and I wasn’t sure how they would turn out. Everything came together so well and they are great! Perfect size for a little treat too.
Yay! So glad you enjoyed the final results, Ashley. Thanks for the lovely review!
Sarah says
These were really good. I used Trader Joe’s ginger snaps instead of graham crackers in the crust and it was yummy. The first couple I took out to serve were left out too long and they turned to soup, so I had to refreeze them. Am I to assume the maximum thaw time is 15 minutes, and you need to eat them mostly frozen? Thanks for a great recipe!
Yum! Yes we suggest keeping them frozen until about 15 minutes before enjoying! We’re so glad you enjoyed them. xo
Theresa says
Your recipes are always so dependable so I was happy to find this. Working with what I had on hand I made a couple quick subs and it turned out great! Had a readymade nut crust I wanted to use up and a tub of frozen CocoWhip so rather than the 3/4 milk and 1/4c oil I used 1c of cocowhip. Subbed Santa Cruz organic lime juice (because I’m too lazy to squeeze and always have it on hand) and used 1/4c maple syrup since I’m sure the cocowhip has sugar in it too. Soaked cashews make such excellent cream! Can’t wait to try again but as minis as you did so it’ll be perfect freezer portions! Thanks for the adaptation!
Amazing! Thanks so much for the lovely review and for sharing your modifications, Theresa!
Mariah says
Delicious! I have made the original recipe and have also adapted it to make a strawberry-lemon cheesecake. You can do all kinds of flavors with this, but including lemon or lime is important to get the tangy cheesecake flavor.
10/10 will do again 👏
Yay! Thanks for the lovely review, Mariah!
Arnaly says
I got all the ingredients except coconut oil! Agh!! Can I sub in melted earth balance instead of the coconut oil?! Making it for my sister who is vegan and GF while I’m visiting her from out of state!
Yes, that should work well!
Alice says
I have never left a comment on a recipe before but this was so amazing I absolutely had to! I did use sweetened condensed coconut milk and it was so so delicious !!! I think it may be one of the greatest desserts I have ever made. I want to keep the entire pie for myself but I also want to share how tasty it is with everyone I know! Thank you!!
Whoop! We’re so glad you enjoy it so much, Alice. Thank you for taking the time to leave a review! xoxo
Megan says
Thank you so much for your help! I made the recipe using 1/2 package of silken tofu in place of the soaked cashews and it turned out WONDERFULLY! (I also replaced half of the graham crackers in the crust with crushed almonds, sunflower seeds, and pumpkin seeds for a little extra nutrition, and that worked perfectly as well). I will be making this again and again!
Yay! We’re so glad they turned out well with those modifications. Thank you for sharing, Megan! xo
Moira says
Hi Megan! What was the size of the 1/2 pkg of silken tofu you subbed with?
Alanna says
I made this with the walnut date base. SO GOOD. Creamy, delicious, citrusy, just the right amount of sweet. LOVE IT!
Yay! Thanks so much for the lovely review, Alanna!
Megan says
We love your gluten free vegan recipes, but my kids are allergic to cashews! Could I maybe replace the soaked cashews in your recipes like this one with something like silken tofu or almonds? I’m sorry to ask, I’m sure it’s hard to come up with a substitute for a substitute but thought I’d try!
Hi Megan, sorry to hear your kiddos can’t have cashews! The next best alternative would be macadamia nuts, but they don’t get quite as thick and creamy, so we’d suggest using less liquid or more macadamia nuts. Blanched almonds would be similar to macadamia nuts, but not quite as creamy. Silken tofu could work, but may require more adjusting to get the texture and flavor right. We’d suggest taking a look at this and this recipe for inspiration. Hope that helps!
Holly says
Hello, I’m so excited to try this recipe! However, I do not consume any type of sugar. I plan on substituting agave with my favorite granulated Stevia, Allulose, erythitol blend. That said, I’m new to baking so how would that work with volume since your recipe calls for a liquid and I want to use a solid? Any adjustments to the liquid ingredients in this recipe? Thank you so so much!
Hi Holly! You want the filling mixture to be creamy, smooth, and pourable. We’d suggest blending it up without adjusting any liquid ingredients first (just omitting the agave), and then adding a bit more coconut milk as needed to make it pourable. Hope this helps!
Alex says
I made this recipe with gluten-free scotch fingers, and I didn’t have as many biscuits crumbs as it called for (only 1 cup) but it turned out great still! When I tasted the mixture I exclaimed out loud “minimalist Baker never misses!”
It’s not as rich as keylime pie, but it hits just about all the same notes.
All your recipes are amazing! Keep up the good work :)
Aw, so kind, Alex! Thank you for the lovely review and for sharing your modifications! xo
Nina says
I am here to report that while I have had this recipe in my internet bookmarks for years, today, Pi Day 2022, is the first time I have made these. I wanted to celebrate the day without feeling compelled to finish a whole pie in a week. Saw several comments about sweetened condensed coconut milk, which I only saw recently in a store and picked up out of curiosity. I used it in place of the agave, and it turned out fine. I didn’t stir the can quite thoroughly before measuring a scant ⅓ cup, but I like things on the less-sweet side. I also used Biscoff cookies in place of graham crackers, which provide some sweetness. I waited the minimum 2 hours before I consumed 3 of the frosty snacks in .14 hours. Happy Pi Day!
Love that you made it for Pi Day, Nina! Thank you so much for the lovely review and for sharing your modifications! xo
Shanda says
Do you think you could leave out the coconut oil without a problem? Or would I need to add something in it’s place? I don’t like to cook with oil for health reasons…
Hi Shanda, It adds creaminess, but you can omit it. We also have an oil-free version for the filling here. Hope that helps!
Scot Granger says
We planted a key lime tree several years ago and they now are producing so I wanted to try a key lime pie recipe. I’ve never made this before and it came out wonderful! Our little key limes are very acidic with a powerful taste. I juiced 6 of them for this first time but we all felt that 6 of them was just not enough lime. I would suggest starting with at least 7 to get more of the key lime taste into the finished product. Everyone wanted the recipe! These are great for an after dinner treat or with coffee in the am! It is hard to stop at just 2 at a time. This recipe is a keeper!
We’re so glad you enjoyed it, Scot! Thank you for sharing!
Sarah says
It tastes great if you focus on the amount of key lime juice rather than the number of limes. The 1/2 cup mentioned in the recipe is perfect. I had tiny key limes and juiced my fingers off to get enough lime juice! I probably used at least ten limes.
So glad you are enjoying them, Sarah. Love your tips as well! Thanks!
Eden says
So great! I used two smaller limes and it was still deliciously limey. Definitely go generous on the butter for the crust. Thanks for the wonderful recipe!
Yay! Thanks, Eden!
Joanna says
I have an allergy to cashews. Do you have any alternative ingredient suggestions?
Hi Joanna! We haven’t tried this recipe without cashews so we cannot guarantee results, but perhaps macadamia nuts or silken tofu would be worth trying? Hope this helps!
Rebecca Amis says
I want to use this recipe to make a pie… Can you help?
Hi Rebecca, other readers have reported making it into a whole pie with success. As written the recipe should make enough for an 8-9 inch pie pan. Hope that helps!
Jaii says
Does this have to stay in the freezer once the until freeze is done? Or can it be moved to the fridge?
They keep best in the freezer, not the refrigerator, thawed for 15-20 minutes before serving. Hope this helps!
