Quick and easy key lime pie recipe starts with a graham cracker crust and filling of egg yolks, sweetened condensed milk, key lime juice & zest.
Preheat oven to 350 degrees F.
Make the Crust: In a medium bowl, stir together the graham cracker crumbs, brown sugar, and salt, ensuring no lumps of brown sugar remain. Drizzle the melted butter over the graham cracker mixture and toss to combine with a fork, ensuring that the mixture is evenly moistened. Press the crust mixture evenly into the bottom and up the sides of a 9-inch pie plate, and pack tightly using the back of a measuring cup. Bake for 10 minutes; transfer to a wire rack to cool to room temperature.
