Ingredient Notes

See recipe box below for ingredient amounts and full recipe instructions.

  • Graham cracker crumbs: Use these along with a little melted butter to make a graham cracker crust (you may also use digestive biscuits, shortbread cookies, or vanilla wafers).
  • Butter: I use salted butter in this recipe but you can use unsalted if you'd like.
  • Egg yolks: Egg yolks are a key ingredient in a key lime pie. See below for ways to use up the leftover egg whites.
  • Lime juice: A traditional key lime pie is made with key limes but you can use the juice from regular limes or bottled lime juice if necessary.
  • Sweetened condensed milk: Used to sweeten and thicken the filling.

Expert Tips

  • Key lime juice is wonderful if you can find key limes and if you can, by all means use them. When I can't find key limes, regular limes will do just fine or use bottled key lime juice.
  • Be sure to let the crust cool for at least 15 minutes before pouring in the filling.
  • In order for the pie to properly set up, it needs to cool in the refrigerator for at least 1 hour before eating.
