The pie is baked for a short time and then refrigerated to thicken up. Top with whipped cream and garnish with slices of Key limes before serving this sweet and tangy lime pie recipe. This is the official Florida state pie.
Preheat oven to 350 F. degrees. Place the unbaked graham cracker crust on a cookie sheet or baking sheet.

Pour the Key Lime Pie filling into the graham cracker crust, scraping the bowl.
