Christmas Cathedral Windows Treat

Makes about 60

1/4 pound butter or margarine
12 ounces semi-sweet chocolate chips
1 cup chopped walnuts
12 ounces colored mini marshmallows
7 ounces sweetened grated coconut

Heat butter and chocolate chips in top of a double boiler over low heat, stirring occasionally, until melted and smooth. Cool slightly. Toss marshmallows and nuts in a large bowl; stir in chocolate. Tear five 9-inch sheets of waxed paper and sprinkle each generously with coconut. Divide dough into fifths and place each fifth on a sheet of waxed paper. Roll tightly into 2-inch diameter logs and refrigerate overnight or until firm. Before serving, unwrap from waxed paper and cut into 1/2" slices.
