2 cups all purpose flour

1 cup firmly packed brown sugar

1 teaspoon salt

1 cup (2 sticks) real butter, melted

Filling: 

1/2 cup all purpose flour

1 (14 oz.) can sweetened condensed milk

2 tablespoons granulated sugar

3 eggs

1/4 cup real butter, melted

2 teaspoons vanilla extract

1 teaspoon salt

4 cups sweetened shredded coconut, divided

Preheat oven to 350*F and lightly grease a 9x13 baking dish, or line with parchment paper.

In a medium bowl, combine all crust ingredients thoroughly until they form a dough. Transfer dough to the prepared baking dish and use a spatula or your hands to press into an even layer. 

Bake crust for 13-15 minutes or until just golden.

As crust is baking, prepare the filling. In a large mixing bowl, add all filling ingredients except for 1 cup of coconut saved for topping. Combine well and pour over baked crust, spreading into an even layer. Top with remaining 1 cup of coconut.

Bake for an additional 25-28 minutes or until set in the middle and coconut begins to brown. Remove pan from oven and place on a wire rack to cool before cutting.
