Preheat oven to 350° (325° for a glass dish). In a 13x9 inch pan, melt butter in oven. Sprinkle crumbs over butter; pour sweetened condensed milk evenly over crumbs. Layer evenly with remaining ingredients; press down firmly. Bake 25 minutes or until lightly browned. Cool. Chill if desired. Cut into bars. Store loosely covered at room temperature.
