My daughter is a huge fan of The Beatles! For her 13th birthday she requested a yellow submarine cake.
I made two cakes from bread loaf pans. The cakes were stacked with frosting in between, and then cut into the submarine shape. I then frosted the cake and used red Twizzlers, Smarties and M&M’s for the windows. The look-out on the top was also Twizzler rope, but a straw would work as well.
