Tip: To make the project more manageable, bake the cake one day and decorate it the next. Tip: The frosting may be made a few days in advance and stored in the refrigerator. Before frosting, bring it to room temperature, then re-whip. Tip: For crumb-free spreading, frost a very thin layer on the entire cake, then spread with a fluffy layer. Tip: To make the orange frosting, tint 1 cup of store-bought or homemade white frosting with orange food coloring. For a vibrant color, use food coloring paste, which is available at kitchen and party supply stores. Tip: Lay all the decorations out before you start. Show the kids our photo and allow room for their own creative additions.
