This Key Lime Pie captures everything I crave in a summer dessert creamy tangy filling and a buttery graham cracker crust with a crown of fresh whipped cream It is the ultimate Florida classic and my go to for potlucks and birthdays alike since it is ridiculously easy and always disappears fast
Last Fourth of July we brought this pie to a family BBQ and not a crumb was left The kids tried to sneak a second piece before the adults even sat down
Ingredients
- Graham cracker crumbs: makes the perfect crisp base look for ones that are fresh and not stale
- Granulated sugar: adds sweetness and structure use pure cane sugar for best result
- Unsalted butter: binds and flavors the crust choose high quality butter for a rich taste
- Egg yolks: create a thick silky custard select large fresh eggs for best color
- Sweetened condensed milk: the backbone of that creamy filling opt for good quality brands for smoothest results
- Key lime juice: gives the signature bold citrus tang fresh squeezed makes a difference but bottled can work in a pinch
- Lime zest: adds fragrant oils and punches up the lime flavor finely grate for best texture
- Heavy whipping cream: whips up light and airy for the topping use very cold cream
- Powdered sugar: sweetens the whipped cream and helps it hold its shape sift to avoid lumps
- Vanilla extract: brings an extra layer of depth real extract has the best flavor
Step-by-Step Instructions
- Make the Crust:
- Mix graham cracker crumbs sugar and melted butter in a bowl until the mixture looks like wet sand Each crumb should feel moistened but not soggy
- Form and Bake the Crust:
- Press the mixture firmly into a nine inch pie dish Make sure to press up the sides evenly Use the flat bottom of a measuring cup to help pack it tightly Bake it at three hundred fifty degrees Fahrenheit for eight minutes then let it cool slightly
- Prepare the Filling:
- Whisk egg yolks and lime zest together for about two minutes The mixture will become paler and thicker which creates a richer texture Gradually whisk in the sweetened condensed milk until fully combined then slowly add key lime juice until smooth
- Fill and Bake the Pie:
- Pour the filling into the prepared crust Smooth the top gently Bake for twelve minutes The edges should look set and the center should still jiggle slightly This ensures a creamy pie that is not overcooked
- Cool and Chill:
- Let the pie cool completely to room temperature then refrigerate for at least three hours preferably overnight Chilling sets the filling for clean slices
- Whip and Top:
- Beat cold heavy cream with powdered sugar and vanilla until soft peaks form Spoon or pipe the whipped cream over the pie just before serving

My favorite part is zesting those key limes The smell just fills the whole kitchen and reminds me of tropical vacations as a kid My family always fights over who gets to lick the beaters after I whip up that sweet creamy filling

Key Lime Pie stores beautifully in the fridge for up to four days Just cover it tightly with plastic wrap or foil so it does not absorb other fridge odors If you want to freeze it do so without the whipped cream topping Wrap well and thaw overnight before serving then add freshly whipped cream
