Combine graham cracker crumbs and melted butter in a mixing bowl. Stir until the mixture resembles wet sand.

Divide the crust mixture evenly among jars, pressing it firmly to create a solid base.

In a separate bowl, beat the cream cheese until completely smooth and creamy.

Add sweetened condensed milk, key lime juice, and Vanilla Extract (Alcohol-Free). Mix thoroughly until fully blended.

In another bowl, whip the heavy whipping cream until stiff peaks form.

Gently fold the whipped cream into the cream cheese mixture, using a spatula to maintain a fluffy texture.

Spoon or pipe the filling into the jars over the crust layer, distributing evenly.

Smooth the tops with a spoon or spatula for a clean finish.

Cover the jars and refrigerate for at least 4 hours, or overnight for best results.

Before serving, garnish with fresh lime zest.
