This was done for a 40th birthday of an avid bike rider. The cake is covered in MMF and crushed cookies and cake crumbs that were leftover from sculpting the cake. The spiral was made by cutting an 8 and 10 inch round. I eyeballed it and played with it until I liked the shape and then covered it with whipped ganache and MMF. The grass was made with royal icing and the trees, bicycle, and figurine are made with Fondant mixed with CMC.
