Creating these delightful No-Bake Mini Key Lime Pies involves several easy steps. Here’s a simple guide to help you prepare them:

1. Make the Crust: In a medium bowl, mix the graham cracker crumbs, melted butter, and sugar until well combined.
2. Press into Cups: Spoon the mixture into mini pie cups or a muffin tin, firmly pressing it down to form an even crust.
3. Chill the Crust: Place the crusts in the refrigerator for about 15 minutes to set.
4. Prepare the Filling: In a large mixing bowl, beat the softened cream cheese until smooth and creamy.
5. Add Condensed Milk: Gradually add the sweetened condensed milk and continue to beat until well mixed.
6. Incorporate Lime: Pour in the fresh key lime juice and zest, mixing until everything is blended and smooth.
7. Fill the Cups: Remove the crusts from the refrigerator, then fill each cup with the lime filling, smoothing the tops.
8. Chill Again: Return to the refrigerator and chill for at least 2-3 hours to let the filling set.
9. Serve: Once set, top with whipped cream if desired, and garnish with lime slices and additional zest.
