Step-by-Step Instructions

Prepare the Crust:

Mix graham cracker crumbs sugar and melted butter until the mixture resembles wet sand. The texture is crucial here press a small amount between your fingers it should hold together without being overly wet. Press the mixture firmly into mini pie tins or muffin liners using the back of a measuring cup for an even layer. Chill for 15 to 20 minutes until the crust feels firm to the touch.

Create the Filling:

Beat the softened cream cheese until completely smooth with no lumps whatsoever. This typically takes about 2 minutes of beating. Add sweetened condensed milk gradually while continuing to mix. The mixture should become silky and slightly thicker. Pour in the lime juice and fold in the zest watching as the mixture magically thickens before your eyes.

Assemble the Pies:

Spoon the lime filling onto each chilled crust dividing it evenly among all shells. Fill each one about three quarters full to leave room for garnishes. Use the back of a spoon to create a smooth surface on each pie gently pressing down and swirling to eliminate air bubbles.

Set and Chill:

Refrigerate the mini pies uncovered for at least 3 hours. The filling needs this time to properly set and develop its flavors. You will know they are ready when the center is firm to a light touch and no longer jiggles when gently shaken.

My absolute favorite part of this recipe is the moment when lime juice hits the sweetened condensed milk mixture. It creates this magical chemical reaction that naturally thickens the filling without any heat. Every time I make these I find myself watching in wonder as the filling transforms before my eyes.

Perfect Crust Techniques

Creating the ideal graham cracker crust makes all the difference in these mini pies. The secret lies in the pressure you apply when forming the crusts. Too gentle and they will crumble when served too firm and they become hard to bite through. I find that pressing with moderate pressure using the flat bottom of a shot glass creates the perfect thickness and density. Let the crusts chill completely before adding filling for best results.

Key Lime vs Regular Limes

While authentic key limes create the classic flavor if you cannot find them standard Persian limes work beautifully too. Key limes are smaller more aromatic and slightly more floral in taste with a higher acidity that cuts through the sweetness of condensed milk. If using regular limes reduce the amount by about one tablespoon to prevent overwhelming tanginess. In either case fresh squeezed juice makes an enormous difference compared to bottled varieties.

Storage Solutions

These mini pies maintain their fresh taste and texture beautifully when properly stored. Keep them in the refrigerator in an airtight container where they will last up to 5 days though the crust may soften slightly over time. For longer storage freeze the pies without any whipped cream topping on a flat surface until solid then wrap individually in plastic wrap and place in freezer bags. They will keep for up to 2 months frozen. Thaw overnight in the refrigerator and add fresh garnishes before serving.
