1½cupsgraham cracker crumbs
6tablespoonsmelted butter
¼cupsugar
Filling
3large egg yolks
1can14 oz sweetened condensed milk
½cupfresh Key lime juiceabout 20–25 small limes
1tablespoonlime zest
Topping
1cupheavy cream
2tablespoonspowdered sugar
½teaspoonvanilla extract
Instructions
Prepare the Crust
Preheat your oven to 180°C (350°F).
In a medium bowl, combine graham cracker crumbs, melted butter, and sugar. Stir until the mixture resembles wet sand.
Chef’s tip: Press a handful in your palm — if it holds its shape, it’s perfect.
Pour the mixture into your pie pan. Use the bottom of a glass or measuring cup to press it evenly along the bottom and sides.
Bake the crust for 8–10 minutes until lightly golden and fragrant.
Remove and let it cool completely while you prepare the filling.
Separate and Beat the Egg Yolks
Separate the egg yolks from the whites (save the whites for meringue if you like).
In a large bowl, beat the yolks on medium speed for 2–3 minutes, until slightly thickened and pale.
Tip: You’ll know it’s right when the yolks lighten in color and leave soft ribbons when whisked.
Add Sweetened Condensed Milk
Pour in the can of condensed milk.
Beat again for 2 minutes until the mixture is smooth and creamy.
The texture should look glossy — that’s when you know it’s ready for the lime juice.
Slowly Add Lime Juice and Zest
With the mixer on low, gradually pour in the Key lime juice while whisking continuously.
Important: Don’t dump it all at once. The acid in the juice thickens the mixture, and adding it too quickly can make it curdle.
Stir in the lime zest for extra aroma and flavor.
Mix just until smooth and combined.
Fill and Bake the Pie
Pour the filling into the cooled crust and smooth the top with a spatula.
Tap the pan gently on the counter to release any air bubbles.
Bake for 15–18 minutes, just until the edges are set but the center still has a slight wobble.
Chef’s note: Overbaking causes cracks, so pull it out even if it feels slightly underdone. It’ll finish setting as it cools.
Cool and Chill
Remove the pie from the oven and cool it on a rack for 1 hour.
Then refrigerate for at least 4 hours, or overnight for the best texture.
Tip: Don’t rush this part. The chill time lets the flavors settle and gives that perfect creamy texture.
Whip the Cream
Just before serving, beat heavy cream, powdered sugar, and vanilla until soft peaks form.
Soft peaks: The cream should hold its shape but still look smooth and pillowy.
Spread or pipe the whipped cream over the chilled pie.
Sprinkle a little lime zest or toasted coconut for garnish if you like.
Slice and Serve
Use a warm knife (dip it in hot water and wipe dry) for clean slices.
Serve cold, ideally with a cold brew or a mojito on the side.
Notes
Key Lime Substitute: Mix equal parts regular lime and lemon juice if real Key limes aren’t available.
Extra Tangy Version: Add an extra teaspoon of zest to the filling.
No Mixer? A whisk works fine — it’ll just take longer to blend.
Make-Ahead Tip: The pie keeps beautifully for up to 3 days in the fridge.
For Meringue Lovers: Top with meringue instead of whipped cream, then toast it lightly with a kitchen torch.
