Leftover Bread Cake is a delicious and creative way to use up stale bread. This moist and flavorful cake is made by soaking the bread in a mixture of milk, eggs, sugar, and spices, then baking it until golden and fragrant. The result is a tender and moist cake with a hint of cinnamon and vanilla. It's perfect for breakfast or as a dessert, and can be served warm or at room temperature.
