How to Make It

Start with these straightforward steps for a flawless pie.

Prepare the crust

Preheat your oven to 350°F (175°C). Crush the graham cracker sheets into fine crumbs if using whole sheets. In a mixing bowl, combine the crumbs, melted butter, and granulated sugar until fully blended. Press this mixture firmly into the bottom and up the sides of a pie dish.

Bake the crust

Place the crust in the preheated oven and bake for 8 to 10 minutes or until golden brown. Remove from the oven and let it cool completely on a wire rack.

Mix the filling

In another mixing bowl, whisk together the fresh key lime juice, lime zest, and egg yolks until well combined. Blend in the sweetened condensed milk until the mixture is smooth and creamy.

Fill the crust

Pour the key lime filling into the cooled graham cracker crust, spreading it evenly with a spatula. Smooth the top and bake in the oven for an additional 15 minutes. Remove and let it cool to room temperature, then refrigerate for at least 2 hours until set.

Make the whipped cream

In a chilled mixing bowl, use an electric mixer to beat the cold heavy cream until soft peaks begin to form. Gradually add the sifted confectioners’ sugar and vanilla extract, continuing to whip until stiff peaks form.

Serve and garnish

Slice the chilled pie into wedges and top each slice with a generous dollop of whipped cream before serving. Enjoy the refreshing flavors!

How to Store It
