This traditional Greek Vasilopita is a rich, aromatic sweet bread essential for New Year's Eve celebrations. Infused with warm cinnamon and delicate mastiha, it features a soft, tender crumb and a golden, glossy crust. The dough is enriched with melted butter and eggs, creating a luxurious texture that pairs beautifully with coffee or tea. Traditionally baked with a hidden coin, the person who finds it in their slice is said to have luck in the coming year. While it requires patience for rising, the result is a fragrant, comforting loaf that brings family together. Serve it fresh from the oven or stored for a few days, as the flavors deepen with time. This recipe captures the authentic taste of Greek holidays, making it a memorable centerpiece for your festive table.
