The Greek New Year's cake that traditionally hides a coin is called vasilopita.
Vasilopita is served at New Year's celebrations in Greece and in Greek communities around the world. A coin, known as a flouri, is concealed inside the cake before it is baked or placed inside afterward, depending on the recipe. The person who finds it is traditionally thought to receive good luck for the year.
The cake is commonly cut just after midnight or on New Year's Day. Families and organizations may make a ceremonial first slice for Saint Basil, followed by slices for household members or guests. Recipes differ by region and household: some versions resemble a sweet bread, while others are closer to a citrus-flavored cake.
The name combines Saint Basil's name with the Greek word for pie or cake. Vasilopita is distinct from tsoureki, a braided Easter bread, and from baklava, a layered pastry filled with nuts and syrup.
