How to Make It

Follow these steps to create a delectable Key Lime Pie.

1. Make the crust

Preheat your oven to 350°F (175°C). In a mixing bowl, combine graham cracker crumbs, granulated sugar, and melted butter. Mix until well combined before pressing the mixture firmly into the bottom and up the sides of a 9-inch pie dish. Bake in the preheated oven for 8 minutes, then remove and allow to cool.

2. Make key lime filling

In a large bowl, combine sweetened condensed milk, key lime juice, and egg yolks. Whisk the ingredients together until smooth and fully mixed. Pour the filling into the cooled crust and spread evenly.

3. Bake the pie

Place the pie in the oven and bake for 10 minutes. Once baked, remove it and let the pie cool to room temperature. Then refrigerate for at least 3 hours or until fully chilled and set.

4. Make whipped cream

In a mixing bowl, beat heavy whipping cream until soft peaks form. Gradually add powdered sugar, vanilla extract, and a pinch of salt while continuing to whip until stiff peaks form.

5. Serve the pie

Once chilled, slice the pie and top each slice with homemade whipped cream. Garnish with slices of fresh lime if desired.

How to Store It

Fridge: Store for up to 3 days in an airtight container.
Freezer: No, it affects the texture of the pie.
Reheat: Not required; serve chilled.

Tips for Best Results
