An intricate, pure white pattern against a chocolate background makes a fancy, but easy-to-do cake design. To guarantee success, use a double-thick doily, sift the confectioners´ sugar and apply sugar heavily. Lift doily off carefully!
Ice cake and let icing crust about 30 minutes. Position doily on cake top.
Using a fine mesh strainer, sprinkle confectioners' sugar over doily openings until filled in.
Carefully remove doily.
