Cake Decorating

sheet cake conversion?

Hi. I want to make a 3D car cake and the tutorial I have calls for 4 sheet cakes to be made and then stacked and carved. I have only ever made Victoria sponge or madeira cakesin round or square. I know sponge is not good for stacking so was going to use madeira recipe but I have no idea how much mixture for each sheet cake, how long to bake or even if madeira would work in this instance. The sheet cake will be 9×13 inches. Or do I need a different recipe?
Thanks in advance

It usually takes me one cake mix for a 9×13 but it depends on how much your mix yields..i would think if it yields at least 2- 8" rounds it would be enough for a9x13 if that helps 😊

Hi I made this cake from a 9×13 rectangle pan, I did 3 layers which were 2inch in height and using a template of the car I wanted held against it. I used a 4 egg mix for each layer using a sponge mix
