Preheat oven to 350° (use 325° if using glass mould). In 13 x 9 inch baking mould, melt butter. Sprinkle crumbs over butter. Pour sweetened condensed milk evenly over crumbs. Top evenly with chocolate morsels, coconut, and nuts; press down gently. Bake 25 to 30 minutes or until lightly browned. Cool thoroughly before cutting. Loosely cover any leftovers.
