How to Make It

Prepare the crust

Combine graham cracker crumbs and granulated sugar in a bowl. Add melted butter and mix until well combined. Press the mixture into the bottom and up the sides of a pie dish. Bake at 350°F (175°C) for 8-10 minutes until golden. Allow it to cool.

Make the filling

In a mixing bowl, whisk together sweetened condensed milk, egg yolks, key lime juice, and lime zest until smooth. Pour the filling into the cooled crust. Bake for an additional 15 minutes, then remove from the oven and cool.

Prepare the whipped topping

In another bowl, beat heavy whipping cream until it begins to thicken. Gradually add powdered sugar and vanilla extract, continuing to beat until stiff peaks form. Spread the whipped topping over the cooled pie.
