Can I ask what size pan you used for this cake??? I have to make “Red” the firetruck from the movie cars. He isn’t as long as a normal firetruck. I was thinking of using a 12×18 sheet pan cause I need to feed 30 so need plenty of cake. Not sure if I should cut in 1/3 or 1/4 and stack…hmmmm. I was actually trying to measure the toy my son has and double the size of him. So hard to know how to do this. Just seeing if anyone had any suggestions.
