I am very new to baking, so this may be a bit of an obvious question, but: My daughter wants an airplane shaped chocolate cake for her birthday. I have seen various ideas where you bake a cake, then cut it into pieces and assemble them. But I was thinking, could I make an airplane-shaped mold, put the mixture in, and bake it whole? Would I have a problem with the thin parts like the tail & wings being overdone while the middle of the fuselage is still uncooked? Would there be any other issues I need to be aware of? Cheers!
