When King Frederick and Queen Gwen have triplet daughters, they're delighted. However, there's a bit of a muddle when they're born, and no one knows which one is the eldest, and therefore the heir. So when King Frederick wants to retire, he has to decide who will be Queen. Will it be Princess Hazel, Princess Apple, or Princess Cherry? He sets his daughters a test--whoever can bake a cake, following the instructions but also adding their own flourish, will rule after him. The princesses all have their individual qualities--but who has the right ingredients to be Queen?
