Step-by-Step Instructions

Step 1: Prepare the Muffin Tin

Preheat oven to 350°F (175°C).

Line a 12-cup muffin pan with paper liners or lightly grease the cups.

Step 2: Make the Graham Cracker Crust

In a bowl, combine:

Graham cracker crumbs
Melted butter
Sugar

Mix until evenly moistened.

The mixture should resemble wet sand.

Step 3: Form the Crusts

Divide the crumb mixture evenly among the muffin cups.

Press firmly into the bottoms and slightly up the sides using the back of a spoon or a small glass.

Bake for 5 minutes.

Allow to cool slightly.

Step 4: Prepare the Filling

In a medium bowl, whisk together:

Sweetened condensed milk
Egg yolks

Whisk until smooth.

Add:

Key lime juice
Lime zest
Salt

Continue whisking until fully combined.

The mixture will begin to thicken slightly.

Step 5: Fill the Crusts

Pour the filling evenly into the prepared crusts.

Fill each cup almost to the top.

Step 6: Bake

Bake for 10-12 minutes.

The centers should be just set but still slightly jiggly.

Do not overbake.

Step 7: Cool and Chill

Allow pies to cool at room temperature for 30 minutes.

Transfer to the refrigerator.

Chill for at least 3 hours or overnight.

Step 8: Make the Whipped Cream

Just before serving, beat together:

Heavy cream
Powdered sugar
Vanilla extract

Whip until medium-stiff peaks form.

Step 9: Decorate

Pipe or spoon whipped cream onto each mini pie.

Garnish with:

Lime zest
Thin lime slices
Crushed graham crackers
Fresh mint

Step 10: Serve

Serve chilled for the best flavor and texture.

Chef’s Tips

Use Fresh Lime Juice

Freshly squeezed juice provides the brightest flavor.

Don’t Overbake

The filling should still have a slight wobble when removed from the oven.

Chill Thoroughly

Proper chilling creates the perfect creamy texture.

Zest Before Juicing

It’s much easier to zest limes before cutting them.

Pipe Whipped Cream Just Before Serving

This keeps the presentation fresh and beautiful.
