Key Lime Tartlets

This post may contain affiliate links. Please read my disclosure policy.

This weekend I had — not one — but two good friends turn 30!!!

Actually, it will be my turn next May. (Which I am strangely really excited about!)

But for my friend Christy’s 30th, which coincided with my monthly rockin’ book club, the birthday girl requested some sort of key lime pie dessert to celebrate. I was going to go with a traditional pie, but after passing by one of my favorite ingredients at the store (these adorable mini phyllo cups), thought it would be fun to try “bite-sized”.

And sure enough, these were SO delicious! Seriously. I’m pretty sure I may have accidentally eaten a handful when garnishing them. :)  There was something about the smooth, citrusy custard paired with the flaky, crispy shells that just seemed like the perfect combination. And thankfully, it looks like the birthday girl and friends thought so too, as they totally dug in at our book club bday celebration.

So for those of you who love key lime pie, or those who love a quick 20-minute dessert, you really, really, really should try these.

  10. You make the cutest things ever! And I just love how beautifully you garnished these!

  11. these are just so darling!! i love it, this is such a great party treat :)

  12. Mmmmmm…I’m trying this with lemon juice instead. I shouldn’t have to change the amounts of anything should I? I’ve never been a huge fan of lime.

  13. Key lime is one of my absolute favorite summer desserts. And I love mini food. This is right up my alley!

  14. I always admire cute little finger bites and these looks fancy pretty :) Your friend is lucky to have you.

  15. Hi Ali,

    Happy b-day to your friends and to you next week:) I wish I had a birthday coming up so I can celebrate with these. I’m not going to wait until next year, have to try these very soon. Beautiful photos and recipe.

  16. I was also excited to turn 30. Life just keeps getting better so why not be excited to see what else it has in store!

    I’ve been thinking about making some yummy little bite sized dessert and you’ve just given me the perfect inspiration. Thank you!

  17. These look so delicious. Going to have to try them soon.

  18. Could these be any cuter?! I bet they delish!

  19. these are the CUTEST bite-sized treats! And even though they are portion-controlled…I so would not be able to stop at just one.

  20. Oh my gosh! So cute — there’s just something so fascinating about little foods! I just tossed a package of those phyllo cups that had gotten lost in my freezer some (very long) time ago. I’m not even sure I had a plan for them when I brought them home. Now I need to go get some again, but I have a plan this time!

  21. Love these…so cute!!!!! I could eat ten of them!

  22. i LOVE key lime pie! i can’t wait to try these!!

  23. these sound amazing!!! do the tarts need to be eaten right away as the package suggest to EAT IMMEDIATELY, or can it be made the day before? i don’t want to serve soggy tarts…thanks ;)

    • Did you end up making these in advance? I’m hosting a baby shower tomorrow and I was hoping to make them tonight. Were they soggy?

  26. I’m wondering about the soggy tarts too… can they be made ahead of time, refrigerated and still stay crispy? thanks. Lyndie

  29. Hi Ali, any thoughts on whether or not these can be made a night in advance? I see that the question has been asked, but I’m not finding an answer. Thanks!

  30. These tartlets looks extremely adorable1!!

  31. Can these be made ahead and frozen? I have a family thing in a few weeks and it’s about 4 hours away. I have a few other things I need to make and would love to make these a few night ahead and then thaw them the day of the event and add whipped cream and line garnish.

  32. I made these for a teacher’s luncheon, and I made them that morning. They were a hit! I kept a few at home for later and the tart shells did get a little soft. I kept the remaining in the fridge over night, and they did get softer that I would want to serve them. They were still delicious but a little on the soggy side! Hope this helps those asking about making them in advance! I will definitely make them again, just serve them soon after!

  33. Hi there! I just wanted to stop over and let you know that I’ve shared this post in a Lemon and Lime Summer Dinner Party inspiration / idea board on my blog
    I hope you can check it out and enjoy the event! <3 The Sparkle Queen

  36. Can you pre-make these fillo tartlets a day ahead?

  37. Has anyone tried to make these a day in advance? Can’t wait to try them but would love to make them the night before

  38. My friend and I made these tarts just a few days ago – but the store was out of the mini phyllo-dough tart shells, so we used small tart pie shells. The amount of custard we had was enough for 8 of those small tart shells. We just had to cook them a bit longer to set, but other than that, they were PERFECT. Great recipe. I love citrus recipes that are still tart, and these were perfect. So perfect that I’m making more tonight. (Using small tart pie shells again because… oh my god, so many minis would be insane! hehe)

  39. This looks wonderful and must try for me! Love keylime! Hugs and blessings, Cindy

  41. Oh my, these look like lovely, tastey treats. I am hoping to make them soon… refreshing for summertime :)

  42. i love this idea my daughter does not want a traditional wedding cake.
    These key lime Tartlets could be the trick. Thanks for the idea

  43. These were so light and yummy! I made them for a girls night dinner this summer. They did take a little longer to “set” which to me means they were semi-firm to the touch. I’d say they took about 18 minutes. I didn’t account for how long it would take to cool so I stuck them in the fridge for a few minutes to cool down. Everyone loved them! They’re a perfect size to have one, or four!

  45. Can i make these the night before without the cream and garnish…. im worried the phyllo will get soggy from the custard?. 

    • Hey Gina, I would make the custard and cream and just assemble everything all together, the day you plan on serving, otherwise I do think the custard might make the phyllo soggy. Good luck, and I hope you enjoy! : )

  46. I plan to make 120 of these today for a party. I’ll take pics. =0
