You end up in impossible situations way too often. The problem with mystery dungeon like games is always this.

not really. You have 84 max hp, and you can basically 1-shot every enemy with your 35 damage sneak attack (breaking line of sight right before attacking).
Even if you don't know about that, you can still fight enemies one at a time, making sure not to let the cake attack. Don't bother eating enemies unless your health is getting low. Prioritize eating cakes. This situation is not only possible, but easy.
