Hi! I made this cake for my son's 3rd birthday. I used a 3D train cake on top and decorated it with buttercream stars and fondant face. I then used a 9 x 13 cake on the bottom and decorated it with buttercream and used fondant for the tracks and oreo cookie crumbs for dirt. The train is a pound cake and the bottom is a vanilla cake with cookies and cream filling. Overall I was happy with my first attempt with Thomas! Thanks for looking.
