Key Lime Pie made with lime juice, sweetened condensed milk, and an easy graham cracker crust. It’s perfectly tart, creamy, smooth-the BEST key lime pie recipe!
Preheat the oven to 350 degrees F. In a medium bowl, stir together the graham cracker crumbs, sugar, and melted butter with a fork. Mix until graham cracker crumbs are moist. Press mixture into a 9-inch pie plate or dish. Use a measuring cup or glass bottom to make sure the crumbs are pressed in firmly. Pat down the bottom and sides. Bake for 12 minutes or until golden brown. Let the crust cool.
While the crust is almost cool, prepare the filling. In a medium bowl, whisk together the sweetened condensed milk and egg yolks. Whisk until well combined. Add in the lime zest, and lime juice. Whisk well.
When the pie crust has cooled to slightly warm or room temperature, pour the lime filling over the pie crust. Bake for 15-17 minutes. Remove from oven and cool on a cooling rack. When cool, chill the pie in the refrigerator. The filling will set up as it cools. Chill completely before cutting and serving.
Cut into pieces and serve cold or at room temperature. Can serve with whipped cream, If desired.
