How to Make It

Start your baking adventure with these simple steps.

Preheat

Preheat the oven to 350°F (175°C).
This ensures your crust bakes evenly and crisply.

Mix

Combine graham cracker crumbs, sugar, and melted butter in a mixing bowl until well blended.
You want a uniform texture that holds together when pressed.

Press

Press the mixture firmly into the bottom and up the sides of a 9-inch pie pan.
Make sure it is even for consistent baking.

Bake Crust

Bake the crust for about 8-10 minutes until lightly golden, then remove and allow to cool.
This step is crucial for developing flavor and texture.

Whisk

Whisk together the egg yolks, condensed milk, key lime juice, and lime zest in another bowl until smooth.
Make sure there are no lumps for a creamy filling.

Pour

Pour the filling into the cooled crust and bake for an additional 15-18 minutes.
Watch for a slight jiggle—this indicates it’s set but not overcooked.

Cool

Allow the pie to cool at room temperature, then refrigerate for at least 3 hours before serving.
Chilling enhances the flavors and texture.

Whip

Whip the heavy cream with powdered sugar until soft peaks form.
This fluffy topping complements the tanginess of the pie.

Spread

Spread the whipped cream on top of the chilled pie and garnish with lime slices.
The lime adds a fresh look and extra zestiness.

How to Store It

Fridge: Keep covered in an airtight container for up to 3 days.
Freezer: No, as cream may separate.
Reheat: N/A, serve chilled.

Tips for Best Results

• Use freshly squeezed key lime juice for the best flavor.
