Makes 2, 11 x 17 pans
2 cups butter
6 cups crushed chocolate cookies (original recipe called for Hydrox; Nabisco Famous Chocolate Wafers worked well for me)
6 cups flaked sweetened coconut
6 cups chopped toasted walnuts
4 cups semi-sweet chocolate chips
4 cans sweetened condensed milk
Preheat oven to 350. In oven, melt 1 cup butter in each pan. Remove pans.
Pour 3 cups of chocolate crumbs into each pan and stir. Spread evenly, pressing down to make crust.
Sprinkle 3 cups coconut, 3 cups nuts, 2 cups chocolate chips over each crust. Drizzle with condensed milk. Bake at 350 degrees for 30 minutes. Cool in pan. Cut into bars.
