1/2 cup fresh lime juice. โฃโฃโฃ3 to 4 regular limes or 20-ish key limes.

To Serveโฃโฃโฃ

1 cup of heavy creamโฃโฃโฃ
1 Tbsp icing sugarโฃโฃโฃ

Equipment Neededโฃ

  • โฃ9-inch pie plate, or a 10″ fluted tart pan. I prefer the tart pan because it’s fancier. โฃ

  • Lime zester, lime juicer, two mixing bowls, cooling rack, measuring spoons, measuring cups.

Key Lime Pie Method

Let’s get down to business.

Double Deep Graham Cracker Crustโฃโฃ

  • Preheat the oven to 350F.โฃ
  • In a medium bowl, combine the graham cracker crumbs, sugar and cinnamon.
  • Add the melted butter and blend well.
  • Use a flat bottomed glass to press the mixture evenly into the bottom and up the sides of your tart pan.
  • Bake for 10 minutes on the lowest oven rack.โฃโฃโฃ

Key Lime Pie Filling

  • In a medium bowl, whip the egg whites until they hold stiff peaks. (Pictured below).
  • โฃIn a large bowl, whisk together the egg yolks, condensed milk and lime juice. โฃMix well.
  • โฃGently fold in 1/3 of your egg whites.
  • Once incorporated, fold in the remaining egg whites.
    โ €โ €โ €โ €โ €โ €โ €โ €โ €
  • Pour mixture into pre-baked crust. 
  • Bake for 20 minutes. 
  • The filling should be just set. It will be puffed up (souffled) when it first comes out of the oven. 
  • Gently place it on a baking rack, it will deflate as it cools. 
“Stiff peaks” will not bend.


Whip your cream to soft peaks and add icing sugar to sweeten.
Serve each piece of pie with a large dollop of cream.
