Okay so I have to make the fire truck from movie cars. He isn’t your normal long fire truck. He’s more squarish in the back. Need to feed 30 people. Anyone ever made this cake and have any pointers. I haven’t done a carved 3d cake so I’m nervous. My guess was using a 12×18 and cutting in thirds. Stacking two on top of each other and then using 3rd slice in portions to build up front cab part. Then somehow carve! If anyone has suggestions, input, any help that would be greatly appreciated!!!
