Graham Cracker Crust Ingredients

Graham cracker crumbs are essential for the crust.
You’ll need 1 1/2 cups.
You can buy pre-made crumbs or make your own.
Granulated sugar sweetens the crust.
Butter binds the crust and adds richness.

Filling Ingredients

Key lime juice is critical.
You can use fresh or bottled.
Sweetened condensed milk thickens and sweetens the filling.
Egg yolks add richness to the pie.
Whipped cream is used for topping.
You may use store-bought or homemade whipped cream.

Crust Preparation

To prepare the crust, start by mixing the ingredients.
Stir together the graham cracker crumbs, sugar, and melted butter.
Ensure all crumbs are fully coated.
Press the mixture into a 9-inch pie plate.
Use a measuring cup to firmly pack the crust.
Bake the crust for 8 to 10 minutes.
Let the crust cool slightly before adding the filling.

Filling Preparation

Making the key lime filling is straightforward.
Whisk together sweetened condensed milk, key lime juice, and egg yolks.
The mixture should be thick.
Pour the filling into the pre-baked crust.
Bake it for 20 minutes.
The pie should be set but still jiggly.
Let it cool completely.
Then chill for 5 to 6 hours.
