How to Make It

Follow these simple steps to create your delicious tart.

Preheat the oven

Preheat your oven to 160°C (320°F) with both top and bottom heat. Prepare a deep tart or pie dish, about 22-23 cm in diameter, with a minimum height of 4 cm for best results.

Prepare the crust

Crush the cookies until fine using a food processor or by placing them in a freezer bag and rolling with a rolling pin. Combine the cookie crumbs with the melted butter and let it sit for a few minutes to ensure proper blending. Press the mixture evenly into the bottom and sides of the tart dish, ensuring a height of about 3 cm, then use a spoon to compact it firmly.

Bake the crust

Bake the crust in the preheated oven for about 13 minutes, then remove it without turning off the oven. Allow the crust to cool slightly.

Make the filling

In a mixing bowl, beat the egg yolks using an electric mixer until creamy. Add the sweetened condensed milk and mix for 3 minutes. Then, incorporate the lime zest and juice, mixing for an additional 3 minutes.

Bake the pie

Carefully pour the filling into the cooled crust. Bake on the middle rack of the oven for 15 minutes.

Cool and chill

Let the Key Lime Pie cool at room temperature, then refrigerate for at least 4 hours, or ideally overnight for the best flavor.

Serve with topping

Before serving, whip the heavy cream with powdered sugar until soft peaks form. Decorate the pie with the whipped cream and garnish with lime slices and zest.

How to Store It

Fridge: Store for up to 3 days in an airtight container.
Freezer: No, cream can separate when thawed.
Reheat: Serve chilled; do not reheat.

Tips for Best Results

• Use fresh, organic limes for the best flavor.
