The Greek New Year's cake containing a hidden coin is called vasilopita.
Vasilopita is traditionally served at New Year in Greece and in Greek communities elsewhere. A coin is baked into the cake, and slices are distributed to family members, guests, or symbolic recipients such as the household, the church, or the work of the family. The person who finds the coin is said to receive good luck for the year.
The name means “Basil's pie” and is connected with Saint Basil the Great, whose feast day is celebrated on January 1 in the Greek Orthodox tradition. One popular legend says that Basil arranged for valuables to be returned to their owners through baked loaves, although historical versions of the story vary.
Recipes differ by region and family. Some vasilopitas resemble a sweet bread, while others are cake-like and flavored with citrus, vanilla, or aromatic spices. The hidden coin is the defining feature, not one universal recipe.
