This pie redefines Florida dessert traditions by blending tropical mango with tangy key lime. The combination creates a perfectly balanced sweet-tart flavor that’s pure sunshine in every bite.
The secret lies in layering fresh mango puree with classic key lime custard in a graham cracker crust. This approach maintains the creamy texture of the original while introducing vibrant fruit notes that elevate the experience.
What emerges is a dessert that honors the classic while feeling fresh and modern. The mango adds natural sweetness that complements the lime’s acidity, creating a harmony that’s unexpected yet undeniably delicious.
Serve it chilled for a refreshing finish to any meal. This version stays true to the original while making it uniquely your own.

| Ingredient | Amount | Notes |
|---|---|---|

| Fresh Mango 🥭 | 3 whole | Ripe, peeled and pitted |
| Key Lime Juice 🍈 | ½ cup | Freshly squeezed preferred |
| Sweetened Condensed Milk 🥛 | 14 oz | 1 can, full-fat for creaminess |
| Large Egg Yolks 🥚 | 3 whole | Room temperature for custard |
| Zest of Key Limes 🍈 | 1 tbsp | Finely grated for aroma |
| Heavy Whipping Cream 🥛 | 1 cup | Optional, for topping |

The mango is everything here. Publix usually has the best selection—look for Ataulfo or Tommy Atkins varieties, ripe but still firm. Graham cracker crumbs are easy to find in the baking aisle, but crushing your own (honey or cinnamon flavor works too) gives better texture. For the key lime juice, Nellie & Joe’s bottled version is a solid shortcut if fresh aren’t available.
No fresh mango? Frozen mango puree (thawed and drained) works in a pinch, though the flavor won’t be quite as bright. Short on key lime juice? Regular lime juice plus a bit of extra zest gets you close. The sweetened condensed milk must be full-fat—low-fat versions won’t set properly. Egg yolks can’t be swapped here; they’re essential for the custard’s richness.
This pie needs at least 4 hours to chill and set completely. Store leftovers covered in the fridge for up to 3 days—though it’s best the first day. The crust softens over time, so eat it quick. Freezing isn’t recommended (the custard can separate).

Step-by-Step Instructions for Mango Key Lime Pie
Here’s the method I’ve perfected for a pie that balances tropical sweetness with citrus tang.
Step 1: Create the Graham Cracker Crust
Preheat your oven to 375°F. In a bowl, combine the 2 cups Graham Cracker Crumbs with the 0.25 cup Granulated Sugar and 0.25 tsp Salt. Stir until evenly distributed—the sugar should be barely visible.
Pour in the 0.5 cup Unsalted Butter (melted and slightly cooled) and mix until the crumbs resemble wet sand. Press this mixture firmly into a 9-inch pie dish, using the bottom of a glass to create an even layer. Bake for 8-10 minutes until the edges are light golden brown.
Let the crust cool completely on a wire rack. This prevents the filling from making the crust soggy. Real talk: a fully cooled crust is non-negotiable for that perfect crisp base.
Step 2: Prepare the Mango Puree
Peel and pit the 3 whole Fresh Mango. Cut the flesh into chunks and place in a blender or food processor. Pulse until completely smooth—you should have about 1½ cups of puree.
Strain the puree through a fine-mesh sieve to remove any fibrous bits. This step ensures a silky texture in your filling. Here’s the thing—mango puree can vary in sweetness, but the Sweetened Condensed Milk balances it perfectly in the next step.
Step 3: Make the Key Lime Custard
In a large bowl, whisk together the 14 oz Sweetened Condensed Milk, 3 whole Large Egg Yolks, 0.5 cup Key Lime Juice, and 1 tbsp Zest of Key Limes. The mixture will thicken slightly as you whisk.
Gently fold in the mango puree until fully incorporated. The color should be a vibrant orange-yellow. Pour this filling into the cooled crust, smoothing the top with a spatula.
Bake at 350°F for 15-18 minutes until the center is just set—it should jiggle slightly when gently shaken. Don’t overbake; the custard continues setting as it cools.
Step 4: Chill and Add the Topping
Cool the pie to room temperature, then refrigerate for at least 4 hours (overnight is ideal). This chilling time allows the custard to fully set and the flavors to meld beautifully.
When ready to serve, whip the 1 cup Heavy Whipping Cream with the 2 tbsp Powdered Sugar and 0.5 tsp Vanilla Extract until soft peaks form. Spread or pipe this over the chilled pie. The contrast of the creamy topping with the tangy-sweet filling is what makes this dish unforgettable.
Pro Tips For Making Publix Mango Key Lime Pie
- Chill the Crust: Press the graham cracker crumb and butter mixture into the pie dish and refrigerate for at least 30 minutes before adding the filling—I learned this the hard way after my first few pies turned into soggy messes.
- Strain the Mango: After pureeing the fresh mango, strain it through a fine-mesh sieve to remove any fibrous bits, or your pie will have an odd texture that’s hard to ignore.
- Use Room-Temp Butter: Let the unsalted butter soften for about an hour before mixing with the crumbs—cold butter makes the crust clumpy, and melted butter makes it greasy.
- Zest the Limes First: Before juicing the key limes, zest them and add a teaspoon of zest to the filling; it brightens the flavor in a way juice alone can’t.
Creative Variations of This Dish
Tropical Coconut Swirl
Add ½ cup toasted coconut flakes to the graham cracker crust for extra crunch. The nutty flavor pairs beautifully with mango. I also fold ¼ cup shredded coconut into the filling for texture. 🥥
Passion Fruit Fusion
Replace ½ cup mango puree with passion fruit puree for a tangier twist. The tropical combo creates a vibrant flavor explosion. Use Nellie & Joe’s passion fruit juice if fresh isn’t available.
Spiced Rum Infusion
Add 2 tbsp dark rum to the key lime custard mixture before baking. The alcohol cooks off, leaving a warm, spiced depth. I recommend Myers’s for its rich molasses notes.
Mini Pie Bites
Use a muffin tin to create individual servings. Press ¼ cup crust mixture into each cup, then fill with the custard. Bake for 12-15 minutes at 350°F. Perfect for parties! 🎉
Mango Glaze Drizzle
Simmer ½ cup mango puree with 1 tbsp honey until thickened, then cool and drizzle over the whipped cream topping. This adds a glossy finish and extra mango intensity.
Citrus Zest Boost
Add 1 tsp orange zest to the filling for a brighter citrus profile. The orange complements the lime beautifully. Use a microplane for the finest texture.

Frequently Asked Questions
Can I use store-bought mango puree?
Yes, but choose unsweetened to control the sugar content. You’ll need about 1½ cups. Fresh puree delivers the best flavor, though.
Why does my filling look runny after baking?
It needs time to set. Chill for at least 4 hours before serving. Overbaking can also cause separation, so stick to 15-18 minutes.
Can I make this pie ahead of time?
Prepare it up to 1 day in advance. Store covered in the fridge, but add whipped cream topping just before serving.
What’s the best way to zest key limes?
Use a microplane for fine, fluffy zest. Wash limes first and avoid the bitter white pith. 1 tbsp is perfect for this recipe.
