Double Stuffed Vanilla Key Lime Pieโ€ฆwith double the crust too. This is not your average key lime pie, itโ€™s super easy, creamy, and made with an extra amount of tang. The filling is made with just a few simple ingredients, plenty of fresh lime, and a touch of sweet vanilla bean. The crust is thick, buttery, and hinted with cinnamon. Put the two together and you have the most mouthwatering pie. Just sweet enough, incredibly luscious, super creamy, tangy, and swirled with vanilla. Finish with lightly whipped cream and lime zest for a tropical summer pie that everyone will love!

There was once a period of time when I said I would never make key lime pie. It just wasnโ€™t a pie that interested me when I was growing up. I never understood why key lime pie was one of my grandpaโ€™s (and brother Brendanโ€™s) personal favorites. If youโ€™re going to enjoy a slice of pie, why not make it a slice of chocolate chip cookie pie? Yes, that was my thinking as a kidโ€ฆand really, just until a couple of years ago.

I never got key lime pie, it just seemed weird to me. Limes are for tacos, not pie. I mean, right?

Wrong. Wrong. So very wrong.

Limes can be used in both sweet and savory recipes. And while I canโ€™t say key lime pie is my absolute favorite pie, I will say itโ€™s incredibly delicious. A chilled pie is perfect for low key hot summer nights. Just be sure to add lime zest and an extra dollop of whipped cream!

So where did the inspiration come from?

Well, I had two sources of inspiration for this pie.

First and foremost, my sister in law, Lyndsie. Lyndsie has been telling me to make key lime pie since the day I met her. Itโ€™s her favorite pie and she has always been annoyed with me that I refused to make it for so many years. So when I told her I was making key lime pie? She just said, โ€œI mean, finally, Iโ€™ve only been telling you to make key lime pie since the day I met youโ€.

And thenโ€ฆshe went on to tell me all the things my key lime pie needs to be. The crust needs to be thick. It needs to be not too sweet, extra tangy, and of course, extra creamy. And for the topping? Well, she actually required me to keep it simple. Whipped cream and lime zest only.

I had some interesting topping ideas, but letโ€™s just say that Lyndsie didnโ€™t quite approve. She said, donโ€™t over-mess with key lime pie! Itโ€™s good as is, but you can make it better with more crust, more filling, extra lime, and a hint of sweetness.

So, thatโ€™s what I did.

My second source of inspiration is my grandpaโ€™s eightieth birthday next week! To celebrate, I thought it would be fun to finally make one of his favorite pies. Yeah, he loves all pie, but he loves Key Lime Pie the most. So happy (early) birthday grandpa! Someday, when traveling is a thing again, Iโ€™ll be making this pie for you the very first chance I get.

Now, onto the details.

So whatโ€™s the most awesome thing I learned about key lime pieโ€ฆother than the fact that itโ€™s actually really delicious?

That itโ€™s such an EASY pie to make, Iโ€™m talking so easy. Just about anyone can make this key lime pie.

Start with your crust. As I mentioned, I made a thick crust using sweet graham crackers, a touch of cinnamon (graham crackers and cinnamon together is my absolute favorite), and salted butter (always salted butter). Then I baked it up in a deep-dish pie plate. All done, super easy. That touch of cinnamon and the use of salted butter are key.

Now, while the crust is baking, make the key lime filling. I listened to Lyndโ€™s and went with an extra tangy and just sweet enough filling. This means heavy on the lime and lighter on the sweetened condensed milk. Instead of more sugar, I used vanilla to really add a layer of flavor and sweetness to the pie. Itโ€™s an unexpected but delicious flavor when paired with the tangy lime.

Then just bake the filling in the crust and in less than thirty minutes youโ€™ll have key lime pie. So easy right? I was shocked this wasnโ€™t a more complicated pie to make, but very pleasantly surprised.

Remember, itโ€™s summer, so simple is the name of the game.

And for serving, whipped cream and just a touch of lime zest. Nothing fancy at all, but sometimes you donโ€™t mess (too much at least) with a classic.

A note on the pie plate.

For my pie plate, I used a deep dish style pie plate. Iโ€™m recommending something similar to this glass pie plate or this stoneware pie plate. You need something a bit deeper to fit the thicker crust and thicker filling.

Loving the idea of serving this pie at your next summer picnic or backyard dinner. Itโ€™s the perfect tropical pie to end a summer night. And my only other suggestion? Add double the whipped cream. If you have double the key lime pie, you need doubles on the topping too!

Oh and maybe add your favorite fruity cocktail as well. Tropical pie, tropical drink. Iโ€™m recommending my creamy coconut lime mojito, or maybe just a fun blackberry margarita.

    i LOVE this recipe, it’s my go-to for key lime pies, but I also often use it as a jumping-off point for other baking experiments. most recently, I added ginger powder to the crust, fresh ginger to the filling, & swapped out the lime juice/zest for lemon juice/zest – & made a lovely lemon-ginger pie perfect for thanksgiving!

    it’s so reliable – you can essentially use any citrus in place of lime to really experiment with the flavors ๐Ÿ™‚

      Hi Anna,
      Love to hear this! Thanks so much for making this recipe so often and your comment! Happy Thanksgiving! XxT

    Such a big hit! I am making two of these pies for my family dinner this evening. I made one last year and everyone was looking for a second slice! I am new to pie making and happy with easy recipes. I would like to see a more fancy pumpkin pie recipe from you to try! Maybe something citrus or currant?

    This is the best pie. Seriously my favorite. I didnโ€™t have key lime pie for 30 years of my life, like you, I thought key limes are not supposed to be in pie form ( so I thought). Iโ€™ll never get that 30 years back but I make this often and itโ€™s always a favorite!!

    Thank you for sharing your recipe and your story!

    1. Tieghan says:

      Thank you so much, Brittany:) So glad to hear you love this pie so much, I appreciate you making it so often! Have the best weekend! xT
