Vasilopita is the Greek New Year's cake that may contain a hidden coin for the person who finds it.
The cake is traditionally cut around New Year's Day in honor of Saint Basil, whose feast day is celebrated on January 1 in Greece. A coin is baked into the cake, and receiving the slice containing it is considered a sign of good luck for the year.
Families and organizations often follow a ceremonial order when cutting slices. Portions may be dedicated symbolically to Christ, the household, absent people, or members of the group before individual slices are distributed.
Vasilopita is not one single standardized recipe. It can resemble a sweet cake or a richer bread depending on the region and family. The hidden coin is the defining feature, not a particular flavor or shape.
