Ingredients for publix mango key lime pie
Tropical flavors meet buttery crust in this crowd-pleasing pie—just like Publix's but better.
| Ingredient | Amount | Notes |
|---|---|---|
| Graham Crackers 🍪 | 2 cups | Crushed into fine crumbs |
| Unsalted Butter 🧈 | ½ cup | Melted, full-fat preferred |
| Key Lime Juice 🍋 | 1 ½ cups | Freshly squeezed, tart variety |
| Sweetened Condensed Milk 🥛 | 14 oz | Standard can size |
| Ripe Mango Puree 🥭 | 1 cup | No added sugar, fresh preferred |
| Granulated Sugar 🍚 | ¼ cup | White or raw preferred |
| Large Eggs 🥚 | 2 whole | Room temperature |
| Heavy Whipping Cream 🥛 | 1 ½ cups | Full-fat, cold for whipping |
| Unsweetened Shredded Coconut 🥥 | ¼ cup | Toasted for crunch |
| Vanilla Extract 🌿 | 1 tsp | Pure vanilla preferred |
| Salt 🧂 | ½ tsp | Fine sea salt |
| Lime Zest 🍋 | 1 tbsp | Freshly grated |
The graham crackers make or break the crust. Honey Maid or Keebler are my go-tos—they crush perfectly. For the butter, Land O'Lakes unsalted melts beautifully without adding saltiness. Fresh key lime juice is non-negotiable here—Florida Keys brand if you can find it, but any tart lime works. The mango puree should be smooth with no chunks, and Trader Joe's has a great no-sugar-added version. If you're using canned mango, drain it well to avoid a watery filling.
No sweetened condensed milk? Evaporated milk plus sugar (1:1 ratio) works in a pinch, but it won't be quite as rich. The whipped cream needs to be cold and full-fat—none of that light stuff. For the coconut, toast it in a dry pan for 3-4 minutes until golden and fragrant. The eggs should be at room temperature to blend smoothly into the filling. If you're short on time, pre-made pie crust works too, but the graham crust is what makes this taste like the Publix version.
The crust keeps best in the fridge for 2 days if you make it ahead. The filling can be prepped a day early and stored in the fridge—just bake when ready. The whipped cream should be added fresh before serving, but you can make it a few hours ahead and keep it chilled. This pie tastes even better the next day once the flavors meld. For a tropical touch, serve with toasted coconut flakes on top—it adds that bakery-style finish.
Why You'll Love This Recipe
- No Crust Fuss: I crush the graham crackers in my food processor—literally 30 seconds—then mix in melted butter until it’s like wet sand. No rolling, no baking, no stress. That buttery crumble just sticks to the pan, and honestly? It’s foolproof.
- Tropical Twist: The mango puree cuts through the tartness of the key lime juice like a bright summer breeze. Sweet, tangy, and creamy all at once—it’s the kind of flavor combo that makes you want to eat it straight from the bowl before it even hits the pie dish.
- Party in a Box: This is my go-to for potlucks because it travels well (no spills!) and feeds a crowd without looking like a last-minute disaster. Plus, the mango flavor feels fancy enough for a dinner party, but the ingredients are simple enough to keep costs low.
- Leftovers? Better: The filling keeps perfectly in the fridge for days, and the crust stays crisp if you store it separately. I’ll be real: I’ve reheated slices for breakfast—yes, really—and they’re just as good cold. Budget-friendly, no-waste, and always satisfying.
Step-by-step instructions for Publix mango key lime pie
This tropical twist on classic key lime pie delivers vibrant flavors and a perfect balance of textures.
👨🍳 Step 1: Make the Zesty Crust
Preheat your oven to 350°F and melt the 0.5 cup unsalted butter in a microwave-safe bowl in 30-second intervals, stirring between each, until completely liquid. In a separate large bowl, combine the 2 cups graham crackers (crushed into fine crumbs) with the melted butter, 0.25 cup granulated sugar, and 0.5 tsp salt.
Mix everything together until you have a moist, sandy texture that holds together when pressed. Press this mixture firmly into a 9-inch pie dish, using the back of a measuring cup to create an even, compact crust. Bake for 10 minutes to set the crust—it should be lightly golden around the edges but still firm to the touch. Let it cool completely before adding the filling.
🍳 Step 2: Prepare the Tropical Filling
In a large mixing bowl, whisk together the 1.5 cups key lime juice, 14 oz sweetened condensed milk, 1 cup ripe mango puree, 1 tbsp lime zest, and 1 tsp vanilla extract until fully combined. The mixture should be smooth with no visible lumps. Here's the thing—this filling is what makes the pie truly special, so don't rush this step.
In a separate bowl, lightly beat the 2 whole large eggs until they're just combined. Slowly pour the eggs into the lime mixture while stirring constantly to create a silky, creamy filling. The texture should be like a thick custard—if it looks too thin, let it sit at room temperature for 5 minutes to thicken slightly before proceeding.
🥘 Step 3: Assemble and Bake the Pie
Pour the filling into the cooled crust, spreading it evenly with a spatula. The filling should come almost to the top of the crust—don't worry if it doesn't fill it completely. Bake in the preheated 350°F oven for 50-55 minutes until the filling is just set but still slightly wobbly in the center. You'll know it's ready when the edges are set and the center has a gentle jiggle—this ensures a creamy texture rather than a firm one.
Remove the pie from the oven and let it cool completely at room temperature for at least 2 hours. This cooling period is crucial—it allows the filling to fully set and develop its signature silky texture. Real talk: Patience here makes all the difference in the final result.
🍦 Step 4: Whip the Cream and Assemble
While the pie is cooling, chill the 1.5 cups heavy whipping cream in the refrigerator for 15 minutes. Using a stand mixer or hand mixer, whip the cream on high speed until it forms soft peaks. In a small bowl, combine the 0.25 cup unsweetened shredded coconut with 1 tablespoon of the lime zest—this adds a beautiful texture contrast and extra zing.
Spread the whipped cream evenly over the set filling, then sprinkle the coconut mixture on top. Use a spatula to gently swirl the cream into the filling if you prefer a marbled look. Chill the pie uncovered in the refrigerator for at least 4 hours or overnight to allow the flavors to meld completely. The coconut will toast slightly as it sits, adding another layer of texture to this already impressive dessert.
Pro Tips For Making Publix Mango Key Lime Pie
- Toast Crumbs Properly: Pulse graham crackers in a food processor until you get fine crumbs—no larger than coarse sand. Toast them in a dry skillet over medium heat for 3-4 minutes, stirring constantly, until they’re golden and smell nutty. I learned this the hard way: skipping the toasting makes the crust soggy within hours, no matter how much butter you add.
- Melt Butter Slowly: For the crust, melt the unsalted butter just until it’s liquid—no browning, no steam. Pour it over the toasted crumbs while they’re still warm, then press firmly into the pie dish. Cold butter pockets won’t distribute evenly, and hot butter can scorch the crust before it sets.
- Strain the Mango: Blend your ripe mango puree, then strain it through a fine-mesh sieve to remove seeds and fibrous bits. The filling will be smoother and set better—no grainy texture ruining the creamy texture. (Yes, even if you’re impatient like me, take the 30 seconds to strain.)
- Chill the Filling: Whip the key lime juice, condensed milk, and mango puree together, then refrigerate the mixture for at least 2 hours before pouring into the crust. This lets flavors meld and prevents the filling from sliding out when you cut slices—trust me, your first slice won’t stick otherwise.
Best sauces and condiments for this publix mango key lime pie
Coconut Whipped Cream
This is my go-to topping for this pie—it adds a tropical crunch that perfectly complements the mango and key lime flavors. Whip 1.5 cups heavy whipping cream with 1 tablespoon powdered sugar until soft peaks form.
Fold in ¼ cup toasted unsweetened shredded coconut and 1 teaspoon lime zest for that extra zing. The coconut should be toasted in a dry pan for 3-4 minutes until golden and fragrant. Spread this mixture over the pie just before serving for that bakery-style finish. 🥥
Lime Curd Drizzle
For an elegant touch, drizzle a lime curd glaze over the pie before adding the whipped cream. Simmer ½ cup sweetened condensed milk, ¼ cup fresh lime juice, 1 tbsp cornstarch, and 1 tbsp butter in a saucepan over medium heat until thickened.
Strain through a fine-mesh sieve to remove any lumps, then drizzle over the pie while it's still chilled. This adds a glossy sheen and intensifies the citrus flavor. 🍋
Mango Caramel Sauce
To enhance the tropical vibe, add a mango caramel sauce drizzle. Blend ½ cup ripe mango puree, ¼ cup heavy cream, and 2 tbsp brown sugar in a blender until smooth. Heat in a small saucepan over low heat, stirring constantly until it thickens to a glossy consistency.
Let it cool slightly before drizzling over the pie. This sauce balances the tartness with a sweet, fruity note. 🥭
Garnish with Fresh Fruit
Fresh fruit adds a vibrant, healthy touch and keeps the pie looking fresh. Top with thinly sliced mango, lime wheels, or kiwi slices arranged in a circular pattern. For extra flair, add a sprinkle of edible gold leaf or a dusting of powdered sugar.
The fruit not only looks stunning but also provides a refreshing contrast to the rich filling. 🍍
Spiced Rum Swirl
For a boozy twist, add a dark rum swirl to the filling before baking. Mix 1 tablespoon dark rum with 1 teaspoon cinnamon and ½ teaspoon vanilla extract, then swirl it into the filling before pouring it into the crust.
The rum adds depth and warmth that pairs beautifully with the tropical flavors. Be sure to bake the pie at 350°F for 50-55 minutes to allow the alcohol to cook off safely. 🍹

Frequently asked questions
Can I make this pie without fresh mango?
Use 1 cup unsweetened mango puree from a can (drained well) or blend 1.5 cups frozen mango chunks with a splash of water until smooth. For extra authenticity, add 1/4 teaspoon mango powder (available online) to enhance the tropical flavor. The texture will be slightly thicker but still delicious.
How do I prevent the crust from getting soggy?
Bake the crust for 10 minutes before adding filling to create a moisture barrier. For extra insurance, sprinkle 1/4 cup crushed graham crackers on top of the baked crust before pouring in the filling. Chill the pie completely before slicing—this helps the filling firm up and keeps the crust crisp.
Can I use store-bought key lime juice?
Store-bought juice works in a pinch, but fresh is ideal for that bright, tangy flavor. If using bottled juice, choose a 100% pure key lime juice with no additives. For extra zing, add 1 extra tablespoon lime zest to compensate for the less intense flavor. The filling will still taste amazing, just slightly less vibrant.
How long can I store this pie?
The pie keeps well in the fridge for 4-5 days when properly stored in an airtight container. For longer storage, freeze the baked (but un-topped) pie for up to 3 months. Thaw overnight in the fridge before adding whipped cream and serving. The texture remains creamy when properly stored.
Why did my filling turn grainy?
Graininess usually happens when eggs cook too long or the mixture isn't smooth enough. For next time, whisk the eggs and lime mixture together gently to avoid incorporating air bubbles. Bake until the center is just set (with a slight jiggle) rather than fully firm. If it happens, blend the filling briefly before baking to restore smoothness.
