Chocolate cake has chocolate in it. Carrot cake contains carrot. At a birthday party, I was really enjoying a slice of cake and asked the birthday child's mother what sort of cake it was. She said "sponge cake". I didn't eat the rest. I didn't know whether it was made from sea sponges or kitchen sponges, but neither seemed very appetising.
