Creating an Easy Lemon Icebox Pie is straightforward if you follow these simple steps:

1. Prepare the Crust: In a mixing bowl, combine the graham cracker crumbs, granulated sugar, and melted butter. Stir until well combined.
2. Form the Crust: Press the mixture into the bottom and up the sides of a 9-inch pie dish. Ensure it’s packed evenly.
3. Pre-Bake the Crust (Optional): If you prefer a firmer crust, pre-bake the crust in a 350°F (175°C) oven for about 8-10 minutes. Allow it to cool completely.
4. Mix Filling: In another bowl, whisk together the sweetened condensed milk, lemon juice, lemon zest, and vanilla extract until smooth.
5. Whip the Cream: In a separate bowl, whip the heavy cream until stiff peaks form.
6. Combine: Gently fold the whipped cream into the lemon mixture until well combined, being careful not to deflate the whipped cream.
7. Fill the Crust: Pour the lemon filling into the prepared crust and spread it evenly.
8. Chill: Cover with plastic wrap and refrigerate for at least 4 hours, or until set.
9. Serve: Once set, slice the pie and serve garnished with additional lemon slices or whipped cream if desired.

These steps ensure that you create an amazing Easy Lemon Icebox Pie that everyone will enjoy!
