These Mini Key Lime Pies are the perfect bite-sized version of traditional Key Lime Pie.
I don’t typically take the easy road on things, unfortunately. In hindsight I always wish I had – like, what was I thinking?? In this case, I had it set in my mind that I wanted to make mini key lime pies, and I wanted them to be in mini tart pans, NOT in cupcake liners and tins like I’d seen in so many recipes online. Learn from my mistakes people, just use the damn lined cupcake tins like everyone else does. So. Much. Easier.
I didn’t own a mini tart pan, so initially I was on the hunt for those aluminum foil pie plates you can buy in the grocery store, mini ones, but I couldn’t find any. My ideal, obviously, was an actual mini tart pan, but I didn’t think I’d find one, especially since I was not willing to pay full price for something I’d use maybe a handful of times.
Trips to a couple grocery stores left me empty handed — why are mini aluminum foil pans so hard to find?? Probably because I live in Canada and it’s virtually impossible to find anything here. Or at least that’s how it seems when you’re on a mission for a very specific thing and can’t find it in the two stores you go to.
I figured I would pop into Homesense to see if I could find anything, though my hopes were not high. If you’ve been to Homesense before, you know it’s a total crapshoot. It’s rare that they have the exact thing you’re looking for at the exact time you’re looking for it.
Well in this case, there it was. One lone mini tart pan staring me right in the face. Just one, and exactly what I was looking for. I figured it was fate. In hindsight, it was actually a test to see if I’d be foolish enough to spend the whole $12 instead of using the perfectly good cupcake tin that was waiting for me at home. I caved and bought it, obviously.
Now, this tart pan likely works perfectly if you’re using a standard pie crust that you trim and press into each tart so it fits. But using a graham cracker crust was a pain in the ass. I had a pretty good makeshift stamper that I could use to press the crust into the bottoms, but the sides were a HUGE pain. It was awkward to press the crust into the sides and get it to stick to the bottom crust.
Halfway through, I gave up and decided that I would just do a bottom crust. I didn’t have the foresight to think that the ones with only the bottom crust may not come out of the pan. They didn’t. The filling totally just glued itself to the sides of the tart pan and wouldn’t budge, even though I placed tinfoil “lifts” under each of the tarts. So those 6 little guys did not get their time in the photo spotlight.
I had extra graham crust and filling, so guess what I did? I got out my cupcake tin and lined it with cupcake liners. Those ones came out perfectly (except that I should have used a bit more filling in each).
Now aside from the whole crust fiasco, I should mention that this is not the easiest recipe. Again, I could have taken the easy route like many recipes out there and used cream cheese or condensed milk. Except that I don’t like cream cheese and I don’t want my key lime pie to taste cream cheese-y, and I didn’t have any condensed milk. But the real reason is that I wanted to modify a recipe we made in school – the lemon sabayon tart – which is, to this day, one of the best things I’ve ever had.
The ingredients for these mini key lime pies are simple — there are only 5. It’s the method that is a bit painful and requires some elbow grease, namely whipping the living daylights out of the filling over a water bath for about 10 minutes. Again, I probably could have used a hand mixer to do this and saved myself both time and energy, but nooooo. In school we used a whisk and did it manually, so I did it that way. Stupid. I now have a blister to show for it. I had flashbacks to school while I was whipping the damn thing, sweating and cursing. Thankfully the end product is worth it.
Perfectly smooth key lime filling with a crunchy graham cracker crust. Heaven.
I do like the look of the tart ones better, but next time I would 100% use the cupcake tins and liners – tastes just as delicious with minimal effort!
If you love Key Lime Pie, you will love this mini version!
Mini Key Lime Pies
Ingredients
Crust:
- 1 1/2 cups graham crackers
- 6 Tbsp unsalted butter melted, 85g
- 1/3 cup granulated sugar
Filling:
- 2 large eggs
- 1/3 cup granulated sugar
- 5 Tbsp key lime juice 6-7 key limes
- zest of 1 key lime
- 4 Tbsp unsalted butter melted, 57g
Instructions
Crust:
- Preheat oven to 350F and line a standard 12 cupcake tin with paper liners.
- In a medium bowl, combine graham cracker crumbs, sugar, and melted butter.
- Divide crust evenly amongst the 12 liners, approx. 1 heaping Tbsp in each. Press firmly into the bottom of each liner.
- Bake for 5-7 minutes. Set aside on cooling rack.
Filling:
- Preheat oven to 300F.
- Prepare a bain marie (water bath) on the stove.
- Once the water is boiling, place eggs, sugar, key lime juice and zest into a large bowl and begin whisking.
- Whisk vigorously over the boiling bain marie until thick and light (approx. 5-10mins). Take on and off bain marie every once in a while to prevent setting/cooking eggs. Alternatively, try using a hand mixer. The mixture is ready when it’s light, thick (like pudding), and ribbons form when you run your whisk through it.
- Remove from heat and whisk in melted butter.
- Pour into pre-baked tart crusts and bake for 5-7minutes until set. The center of the pies should jiggle just slightly the pan is nudged.
- Cool completely on a wire rack, then place in fridge for at least 2 hours.
- Serve cold, topped with whipped cream if desired.

Hi Olivia!
This is the only recipe I’ve found so far that doesn’t call for condensed milk! I hate using that stuff. What do you think about making this in a larger tart pan? I have 5 inch ones, a 9 inch, and an 11 inch. What do you think would work??
Thank you!
Olivia says
Hi Alyssa! I actually have no idea which one would work best. It’s been a couple years since I made this and I wouldn’t want to steer you wrong. My gut says 9″ though, but don’t hold me to it!! Haha. Let me know if you try it 🙂
Alyssa says
Thanks for your response! I’ll keep you updated if I decide to try it in the 9” 😊
Cookiegirl says
Since what the baking step dues is set the filling, and tarts are basically disks so height (top to bottom) doesn’t change no matter the diameter of the pan or volume of filling, you could probably just bake for the same amount of time.
Linda says
This is exactly how you learn when young that proper utensils are worth the price. Some reasearch online will help to know the shortcomings of different things.
I bought my tart pans with removable bottoms from Amazon at a very good price and throughout the years I have used them often.
Your tarts look wonderful and your perseverance is admirable!
Olivia says
Thanks so much Linda! And it’s so true — investing in high quality tools is the way to go!!
Giselle says
I will not bake anything with sweetened condensed milk in it, so I was happy to find this recipe. These are delicious. Thank You.
Olivia says
So glad you liked them Giselle!! 🙂
Elizabeth Federman says
Olivia, I’m so happy that I happened upon this recipe. I had way too many limes and found this. Hands down, it’s the best Key Lime filling I’ve ever tried. I almost shed a tear imagining you wisking this by hand. The electric mixer was most definitely my friend today. Can’t wait to try some of your cakes. Thanks for spreading joy!
Olivia says
Hi Elizabeth! I think I till have PTSD from that whisking by hand, haha! Never again. The filling was delicious though and I am so glad you liked it 🙂 You’ll have to let me know which cakes you try!
Deanna says
These look amazing!! Do you use salted or unsalted butter?
Olivia says
Hi Deanna! I use unsalted butter. Will update the recipe!
Pam says
This dessert is the bomb. I have an indoor keylime tree that produced enough this year to make this yummy dessert. My husband has celiac disease so I used a gluten free shortbread cookie and we both loved. They also freeze well. Thank you for sharing this recipe.
Olivia says
Hi Pam! I’m so glad you liked these and I love the shortbread cookie idea! I’ll have to try that 🙂
Lindsay says
Is it imperative to use bain marie? I assume that it is. But I just wanted to know if anyone has done it without?
Olivia says
Hi Lindsay, for this particular recipe, yes. There may be other Key Lime Pie recipes out there that use different ingredients though!
Ella J says
Hi! The person I am making this for doesn’t eat processed sugar and so I was wondering how I should alter the recipe/what sugar I should use? Thanks
Olivia says
Hi Ella, you could try using honey or something similar, though I haven’t tried it so can’t guarantee the results.
Cindy says
also try coconut sugar, or agave nectar, even though nectar would liquefy it more.
Lori says
Made these for a party and they were delicious. I used a regular pie crust because I dont like graham cracker crust but the pie custard is yummy. Cant wait to make them again.
Olivia says
Hi Lori! So glad you liked them 🙂 I love the custard too!
Brandy says
Love your site – just found it. I made this recipe today, but I only had enough filling for 10 tarts. I followed the directions exactly except for using regular lime juice in stead of key lime (I have some I need to use). Any ideas? Maybe more lime juice?
Thanks!
Olivia says
Hi Brandy! As long as you used the same amount of line juice 5Tbsp, it shouldn’t make a difference. The only thing that comes to mind is maybe you had slightly smaller eggs or you could have whipped the filling a bit more to incorporate more air. I hope you liked them!!
Brandy says
Thanks for the response! I haven’t eaten them yet…..they’re still chilling 🙂 Maybe I will try with a hand mixer next time. After all, I have a box of graham crackers and a bottle of juice.
Olivia says
I am for SURE using a hand mixer next time. Hand whipping is too much of a work out! haha
Jacquie Favrin says
Hi Olivia!
So my husband has asked me to find a key lime pie recipe with a meringue top! Could I use this recipe with a 9″ graham cracker crust?
Olivia says
Hi Jacquie! You could totally use this recipe, but I would suggest doubling it to ensure you have enough to fill a 9″ pie. Let me know how it turns out 🙂
Crystal says
I love your blog! Your pictures are amazing! I am from Vancouver, BC, born and raised! I now live in Edmonton, AB. I just started my blog in March, having so much fun learning the food photography portion!
Olivia says
Thanks Crystal!! So funny, I grew up in Edmonton! Going to peek at your blog now 🙂
Laureen Fox says
Those Mini Key Lime Pies look delish! I had the idea rolling around in my head to make some gluten free (for me!). Gluten free flours are notorious their baking pan stickability. I will def use the cupcake liners!
Olivia says
Thanks Laureen! DEFinitely go with the cupcake liners! Haha.
Shareba @ In Search Of Yummy-ness says
I hate when things stick to baking pans! I agree though, the tarts are super cute! I’m sure it tastes great no matter what shape they are 🙂
Olivia says
Thanks Shareba! 😀
Sofia // From the Land we Live on says
I love the crust technique and the cupcake ones are also cute! I’m with you on the filling…it sounds like one of my favourite lemon tarts. Way better than cream cheese or condensed milk!
Olivia says
Thanks Sofia! I think I’ll try it with condensed milk next time just to see how it turns out 🙂
Melissa says
I had a mini key lime pie at rustique pies in Montreal in May and i was hooked! Yours are even prettier and i bet that cream filling is just divine!
Olivia says
Thanks Melissa!! That’s so nice of you to say. I love a good key lime pie!
Manila Spoon (Abby) says
Perfect little bites of delicious key lime pie for portion control! Not that I will be able to exercise self-control as these pies look totally scrumptious!!!
Olivia says
I know, right? Portion control means having 2-3 minis, haha.
Rachel @ Simple Seasonal says
What a beautiful dessert. It looks like your hard work and patients paid off. Key Lime Pie I associate with some amazing college spring break memories. Not the wild kind… More the sitting on a boat eating a key lime pie while watching the sunset kind. Looking at your cute little pies, aside from making me want one, takes me back to that memory!
Olivia says
Aww, thanks so much Rachel! That sounds like a pretty awesome memory! 🙂
allie @ Through Her Looking Glass says
Ha Ha! you bought the tart pan. YAY for Olivia. I love it when I do a simple splurge I know I shouldn’t. It’s just delicious, especially when we’re talking tart pans. Wish you lived (pun intended) around the corner. I have a beaucoup of little tart pans with removable bottoms. I was lucky enough to score them at yard sale years ago for something like $3. I’ve definitely gotten my money’s worth. I love anything key lime and that includes your adorable tarts here. The photos are just beautiful. Wish I could sample one….
Olivia says
Thanks Allie!! That’s exactly what I need, mini tart pans with removable bottoms! They are now on my list. I have since returned the pan I bought (shhh!), it just wasn’t worth it, even for only $12.
Cali @ Cali's Cuisine says
Heaven indeed! Sometimes it is fun to get in the kitchen to have fun working on a more complicated recipe. Looks like this was a smashing success. I L-O-V-E key lime anything and wish I could reach through my computer screen to grab one of your tasty mini key lime morsels! YUM!
Olivia says
Thanks Cali! Key Lime is one of my fave desserts too 🙂
