I know, I know, Key lime pie is already amazing, but trust me, that little bit of mango? It takes it to a whole new level of YUM.
I stumbled upon this flavor combo totally by accident, actually. I was making a Key lime pie for a BBQ (you know, trying to be all domestic and impressive), and I realized I was short on limes. But I had a ton of ripe mangoes from my neighbor’s tree practically begging to be used. So, I thought, “What the heck?” and threw some mango puree in there. Wow! Mind. Blown.
The tartness of the Key lime with the sweet, almost creamy mango? It’s like a party in your mouth! This Mango Key Lime Pie recipe is now my go-to for potlucks, summer dinners, or, let’s be honest, just a regular Tuesday when I need a little pick-me-up. It’s seriously that good. And easy? Oh honey, it’s SO easy. You’re gonna love it!

Ingredients for Your Mango Key Lime Pie
For the Graham Cracker Crust
Alright, let’s gather our goodies! For the crust, you’ll need:
- 1 1/2 cups graham cracker crumbs (That’s about 10-12 full graham crackers, crushed. I just throw ’em in a zip-top bag and whack ’em with a rolling pin – super therapeutic!).
- 1/3 cup sugar (Plain ol’ granulated sugar is perfect!)
- 6 tablespoons melted butter (Unsalted is best, but if you only have salted, just skip adding a pinch of salt later.)
For the Mango Key Lime Filling
Now for the star of the show – the filling! You’ll need:
- 2 (14 ounce) cans sweetened condensed milk (Make sure it’s *sweetened condensed milk*, not evaporated milk – big difference!).
- 1 cup Key lime juice (Freshly squeezed is always best! It’s about 30-40 Key limes, but honestly, bottled Key lime juice works in a pinch. Just try to get a good quality one!)
- 1 cup mango puree (Okay, you can buy this, but it’s SO much better if you just blend up a ripe mango! Just peel and chop about 2 large mangoes and whiz them in a blender or food processor until smooth. Trust me, you’ll taste the difference!)
- 1 teaspoon lime zest (Just grate the outer green part of a lime – be careful not to get the white pith underneath, it’s bitter!)
For Garnish
And finally, to make it pretty:
- Whipped cream, for serving (Store-bought is totally fine, but homemade is even better! A little vanilla extract in there? Mwah!)
- Mango slices, for serving (Grab a ripe mango, slice it up, and arrange them prettily on top. Or, you know, just throw ’em on there. Whatever works!)
How to Make Mango Key Lime Pie: Step-by-Step Instructions
Preparing the Graham Cracker Crust
Okay, first things first, let’s get that crust going! Preheat your oven to 350 degrees F (175 degrees C). This is important, don’t skip it! In a bowl (any bowl will do, I usually grab my biggest!), toss together those graham cracker crumbs, sugar, and melted butter. Mix it all up until it looks like wet sand. Now, press that mixture into the bottom of a 9-inch pie plate. You want it nice and even, so use the bottom of a measuring cup to really pack it in there. Bake for 8-10 minutes. Keep an eye on it – you want it lightly golden, not burnt! Let it cool COMPLETELY. I’m serious, completely. Otherwise, you’ll have a melty mess later.
Making the Mango Key Lime Filling
While that crust is cooling, let’s whip up the filling! Grab a large bowl (a clean one, of course!) and whisk together the sweetened condensed milk, Key lime juice, mango puree, and lime zest. Whisk it good, until it’s nice and smooth. It’ll be pretty thick, and that’s exactly what you want. Now, gently pour that lovely filling into your cooled crust. Doesn’t it look pretty already?

Baking and Cooling Your Mango Key Lime Pie
Alright, into the oven it goes! Bake for 15-20 minutes, or until the filling is set. You’ll know it’s ready when it doesn’t jiggle too much when you gently shake the pie plate (careful, it’s hot!). Let it cool completely on a wire rack. Seriously, don’t rush this! Then, cover it with plastic wrap and refrigerate for at least 2 hours. The longer, the better, honestly. This is where the magic happens and the filling sets up perfectly.
Garnishing and Serving
Okay, the moment we’ve all been waiting for! Time to make it look extra fancy. Dollop some whipped cream on top (as much as your heart desires!), and arrange some pretty mango slices. And there you have it – a gorgeous, delicious Mango Key Lime Pie ready to wow everyone! Slice it up and watch it disappear!
Tips for the Perfect Mango Key Lime Pie
Using Fresh Key Lime Juice
Okay, so listen, fresh Key lime juice REALLY makes a difference. I know, I know, squeezing all those tiny limes is a pain, but trust me, it’s worth it! Bottled juice just doesn’t have the same zing. To juice ’em, just roll the limes on the counter with your palm – this helps release the juice. Then, cut ’em in half and squeeze away! A citrus juicer definitely helps speed things up, but even just using your hands works fine. Careful, those little guys can squirt!
Ensuring a Cool Crust
I cannot stress this enough: your crust needs to be COMPLETELY COOL before you pour in the filling. Seriously! If it’s even a little bit warm, the filling will melt and you’ll end up with a soggy mess. Nobody wants that! So, be patient. Let it cool on a wire rack until it’s totally room temperature. You can even pop it in the fridge for a few minutes to speed things up (shhh, don’t tell anyone I said that!).
Setting the Filling Properly
Patience, my friend, patience! This Mango Key Lime Pie needs time to chill in the fridge so the filling can set up properly. Two hours is the minimum, but honestly, I like to let it sit overnight. It just gets better and better! If you try to slice it too soon, it’ll be all runny and sad. So, resist the urge to dig in right away and let that filling do its thing!
Mango Key Lime Pie Variations
Adding a Coconut Crust
Ooh, wanna take this pie to the next level of tropical deliciousness? Try adding some shredded coconut to your graham cracker crust! Just mix about 1/2 cup of sweetened shredded coconut in with the graham cracker crumbs, sugar, and butter. It adds a little extra sweetness and a lovely chewy texture. My favorite part is the subtle coconut aroma while it bakes. Trust me, it’s divine!
Using Different Fruits
Okay, so mango is amazing, but don’t be afraid to experiment! Pineapple would be a fantastic substitute – it has that same tropical vibe. Or, if you’re feeling adventurous, try adding some passion fruit pulp to the filling. Just strain out the seeds first, unless you like a little crunch! A mix of mango *and* pineapple? Now we’re talking! Just make sure you keep the total amount of fruit puree the same (about 1 cup) so the filling sets properly.
Making Mini Mango Key Lime Pies
How cute would it be to make individual mini Mango Key Lime Pies? Super cute! Just press the graham cracker mixture into muffin tins instead of a pie plate. You’ll want to reduce the baking time – start checking them after about 8 minutes. These are perfect for parties or when you just want a little personal-sized treat. Plus, you don’t have to share!
Serving Suggestions for Your Mango Key Lime Pie
Complementary Desserts
Okay, so you’ve got this amazing Mango Key Lime Pie… what else could you possibly need? Well, if you’re going all out, a little something chocolatey would be a perfect contrast! Think fudgy brownies or dark chocolate truffles. My personal favorite is a scoop of vanilla bean ice cream right next to the pie. The creamy vanilla really complements the tartness of the Key lime and mango. Yum!
Drink Pairings
Alright, let’s talk drinks! For a daytime treat, you can’t go wrong with a refreshing glass of iced tea. A fruity herbal tea would be especially delicious. If you’re feeling a little fancier, a crisp white wine like a Sauvignon Blanc or Pinot Grigio would pair beautifully with the pie’s tropical flavors. And for a truly indulgent treat? A Mango Margarita! Just sayin’ . Careful, they’re addictive!
Storing Your Delicious Mango Key Lime Pie
Refrigerating Leftover Pie
Okay, so you’ve managed *not* to eat the entire Mango Key Lime Pie in one sitting? Wow, I’m impressed! To keep those leftovers fresh and yummy, just cover the pie tightly with plastic wrap or foil. You can also pop it in an airtight container if you have one big enough. It’ll keep happily in the fridge for up to 3-4 days. Though, let’s be real, it probably won’t last that long!
Freezing Mango Key Lime Pie
Want to save some of this tropical goodness for a rainy day? You can totally freeze your Mango Key Lime Pie! The key is to wrap it *really* well to prevent freezer burn. I like to wrap it in plastic wrap first, then in a layer of foil. For extra protection, you can even put it in a freezer-safe bag or container. It’ll keep in the freezer for up to 2-3 months. When you’re ready to eat it, just thaw it in the refrigerator overnight. The texture might be *slightly* different after freezing, but it’ll still be delicious!
Frequently Asked Questions About Mango Key Lime Pie
Can I use regular limes instead of Key limes for Mango Key Lime Pie?
Okay, so here’s the deal: Key limes have a *totally* unique flavor – they’re more tart and aromatic than regular limes. But, if you can’t find Key limes (they can be tricky!), you *can* use regular limes. Just know that the flavor will be a little different. You might want to use slightly less juice, since regular limes can be a bit more intense. Taste as you go and adjust to your liking! No biggie!
How do I prevent the graham cracker crust from becoming soggy in my Mango Key Lime Pie?
Ugh, soggy crusts are the WORST! Luckily, there are a few tricks to avoid them. First, make sure you pre-bake your crust! That helps it get nice and crispy. Also, make sure you’re using enough melted butter – it acts like a sealant! Press it in really firmly, too. Some people even brush the cooled crust with a little melted chocolate before adding the filling – genius, right?!
Can I make Mango Key Lime Pie ahead of time?
Oh, absolutely! This Mango Key Lime Pie is actually *better* if you make it a day or two in advance! It gives the flavors time to meld together and the filling to set up perfectly. Just keep it covered tightly in the fridge. It’ll be ready and waiting whenever you need a little slice of tropical paradise!
