Bake a round cake the size that you need.
With an icing filled bag and round tip, size #5, draw the superman
emblem on the cake surface. You can either draw S for Superman or the
child’s first letter of their name. For example, the cake in the
picture is for a little boy named Ryan, so I drew an R instead of the
S.
You will use a star tip, size #18 to do the entire cake.
Make a red colored icing and do the letter and the border and the sides of the cake.
Make yellow icing and fill in the background areas.
