The term "cake" has a long history. The word itself is of Viking origin, from the Old Norse word "kaka".
In their oldest forms, cakes were modifications of bread. The ancient Greeks called cake πλακοῦς (plakous), which was derived from the word for "flat", πλακόεις (plakoeis). It was baked using flour mixed with eggs, milk, nuts, and honey. They also had a cake called "satura", which was a flat, heavy cake. During the Roman period, the name for cake became "placenta", which was derived from the Greek term. A placenta was baked on a pastry base or inside a pastry case. Early 14th century cakes in England were also essentially bread: the most obvious differences between a "cake" and "bread" were the round, flat shape of the cakes and the cooking method, which turned cakes over once while cooking, while bread was left upright throughout the baking process.
