Creamy and rich with just the right amount of zing, this Key Lime Pie is simply the best! You’re only a few ingredients away from this American classic.




  • 1 1/2 cups graham cracker crumbs
  • 1/3 cup sugar
  • 6 tablespoons butter, melted


  • 2 cans (14 oz each) sweetened condensed milk
  • 3/4 cup key lime juice
  • 1/2 cup sour cream
  • 1 1/2 teaspoons key lime zest
  • Whipped cream, optional


  1. Preheat the oven to 350ºF.
  2. In a large bowl, combine the graham cracker crumbs, sugar and butter. Stir until the mixture is combined and has a sandy texture.
  3. Pour the mixture into a deep-dish pie pan. Press the crumbs evenly along the bottom and up the sides of the dish. (I like to use a flat bottomed cup or measuring cup to make sure the crumbs are firmly pressed in and even.)
  4. Bake the crust in the preheated oven for 7 minutes. Remove and allow to cool.
  5. In a large bowl, whisk together the sweetened condensed milk, lime juice, sour cream and lime zest until smooth.
  6. Pour the filling into the cooled graham cracker crust. Smooth out the top.
  7. Return the pie to the oven to bake for an additional 10 minutes, or until just set.
  8. Allow the pie to come to room temperature before covering and refrigerating until completely chilled, several hours or overnight.
  9. Served topped with whipped cream, if desired.
