Cream butter and shortening, adding sugar gradually. Add eggs, one at a time, and continue beating well after each. Blend in flavoring, flour and Sun Drop. Turn into a large, greased and floured tube pan. Bake in a 325 degree oven for one hour and 15 minutes or until tests done. Turn out on rack.
Glaze by melting 2 tablespoons butter and blend with 2 cups confectioners' sugar and 2 tablespoons Sun Drop. Spoon glaze over hot cake on rack over waxed paper, spooning glaze that slides off cake back up over cake.
