Magic Cookie Bars
Melt the margarine in the microwave. In a small bowl, add the graham cracker crumbs and the melted margarine. Stir well, and then use the mixture to cover the bottom of a buttered 9 x 13 x 2 cake pan. Top with a layer of coconut, then a layer of chocolate bits, then a layer of nuts if desired. Pour the cup of condensed milk evenly over the whole top. Bake at 350 degrees for 30 minutes. Let it cool before cutting into squares.
