Shape is cut from a sheet cake. Base for side and center "engines" are cut from the unused cake pieces. "Engines" are iced ice cream cones. "Flames" from inside and below center engine are iced bits of cake. "Flames" from side engines are cut up tissue paper (non-edible obviously). Whole cake is allergen free - no nuts, dairy, eggs or gluten. Thanks to Cherrybrook mix! When I used to make eggless cakes w/ my own ingredient substitutions I always had trouble w/ consistency and maintaing shape.
