⁣I call it a “double-deep graham cracker crust,” and my friends, I believe it is the only way a graham cracker crust should ever be made. ⁣⁣⁣Please don’t come at me with skimpy graham cracker crusts, ever.

Key Lime Pie Ingredients

Key Lime Pie Ingredients

Double-Deep Graham Cracker Crust

⁣⁣⁣2 cups Graham cracker crumbs⁣⁣⁣
1/4 cup brown sugar⁣⁣⁣
1 tsp ground cinnamon⁣⁣⁣
8-9 tbsp unsalted butter, melted⁣⁣⁣

Key Lime Pie Filling⁣⁣⁣

2 large egg whites, at room temperature. ⁣⁣⁣
4 large egg yolks⁣⁣⁣
1 (300 ml) can of sweetened condensed milk⁣⁣⁣
1/2 cup fresh lime juice. ⁣⁣⁣3 to 4 regular limes or 20-ish key limes.

To Serve⁣⁣⁣

1 cup of heavy cream⁣⁣⁣
1 Tbsp icing sugar⁣⁣⁣

Equipment Needed⁣

  • ⁣9-inch pie plate, or a 10″ fluted tart pan. I prefer the tart pan because it’s fancier. ⁣
  • Stand mixer fitted with the whisk attachment or a hand blender. ⁣⁣⁣
  • 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 Crust⁣⁣

  • Preheat the oven to 350F.⁣
  • 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.⁣⁣⁣

Key Lime Pie Filling

  • In a medium bowl, whip the egg whites until they hold stiff peaks. (Pictured below).
  • ⁣In a large bowl, whisk together the egg yolks, condensed milk and lime juice. ⁣Mix well.
  • ⁣Gently fold in 1/3 of your egg whites.
  • Once incorporated, fold in the remaining egg whites.
  • 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.
