12th night cakes were very elaborate with firm (royal) icing and many decorations. In the 1870s, Queen Victoria outlawed the celebration of Twelfth Night as a day of partying, because the celebrations had become too riotous and out of control. Consequently, Twelfth Night cake morphed into a dried fruit Christmas Cake.
In France they have the Kings’ cake, which also has a token inside. Being French it is an elegant fève, a tiny ceramic figure. The cake is traditionally bought together with a cardboard crown, so the finder of the fève can be crowned King or Queen for the day.
