Key lime pie traces its roots to the Florida Keys, where the tart fruit grew in abundance. The original dessert emerged in the late 19th century as a simple custard topped with a crust. Over time, bakers refined the balance of sweet and sour, creating a beloved American classic. This mini version captures that heritage while offering a convenient, bite‑size presentation.

Essential Ingredient Guide

- Sweetened condensed milk: Adds creaminess and balances the lime acidity.
- Butter: Melted butter binds the crust and adds richness.
- Lime zest: A little zest lifts the aroma and adds a speck of green.
- Powdered sugar: Dusted on top for a gentle sweet finish.

1 1/2 cups graham cracker crumbs
-
02
4 tbsp melted butter
-

2 tbsp sugar
Filling
-
01
1 cup sweetened condensed milk

Instructions
Preheat the oven to 350°F (175°C).
In a bowl, combine graham cracker crumbs, melted butter, and sugar; stir until the mixture resembles wet sand.
Press the crumb mixture firmly into the bottoms and up the sides of a standard 12‑cup muffin tin, creating a small crust for each pie.
Bake the crusts for 6‑8 minutes, just until they turn lightly golden; set aside to cool.
In a separate bowl, whisk together condensed milk, lime juice, lime zest, and egg yolks until smooth.
Pour the filling into each cooled crust, filling them almost to the top.
Return the tin to the oven and bake for 8‑10 minutes, until the filling is just set but still slightly wobbly.
Remove from oven, let cool to room temperature, then chill in the refrigerator for at least 1 hour.
Dust each mini pie with powdered sugar and add a lime wheel garnish if desired.
