Directions

Preheat your oven to 350°F (175°C).
In a medium bowl, combine graham cracker crumbs, melted butter, and sugar. Mix until well combined.
Press the mixture evenly into the bottom and up the sides of a 9-inch pie dish to form the crust.
Bake the crust in the preheated oven for 10 minutes, then let it cool while you prepare the filling.
In a large bowl, whisk together the egg yolks and sweetened condensed milk until thick and creamy.
Stir in the key lime juice and lime zest until fully incorporated.
Pour the lime filling into the cooled pie crust.
Return the pie to the oven and bake for 15 minutes or until the center is set.
Allow the pie to cool at room temperature, then refrigerate for at least 3 hours before serving.
Top with whipped cream before serving, if desired.

Variations & Tips
For a crust that packs a bit more crunch and flavor, consider adding a tablespoon of finely chopped pecans to your graham cracker mixture. If fresh key limes are hard to come by, bottled key lime juice, found in most supermarkets, can be a good alternative. For a slightly different take, add a tablespoon of cream cheese to your filling for a richer texture. Experiment with a meringue topping instead of whipped cream for a more festive pie.
