For the crust:
- 1 1/2 cups crushed graham crackers (about 2/3 of a sleeve)
- 2 tbsp. sugar
- 1/3 cup butter, melted
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:
- 3 cups sweetened condensed milk
- 1/2 cup light sour cream
- 3/4 cup key lime juice
- 1 tbsp. grated lime zest
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.
