For the crust:
Preheat oven to 350 degrees F. In a small bowl, combine the crumbs and sugar; add butter and blend well. Line a 9-inch pan with aluminum foil. Press cruss onto the bottom of the lined pan. Bake for 8 minutes; cool on wire rack.
For the filling:
In a medium bowl, combine condensed milk, sour cream, lime juice, and lime zest. Mix well and pour onto graham cracker crust.
Bake in preheated oven for 5 to 8 minutes, until tiny pinhole bubbles burst on the surface of pie. DO NOT BROWN! Allow to cool to room temperature. Chill pie thoroughly before serving (at least 3 hours). Cut into 16 bars; garnish with whipped cream and toasted coconut.
