The world's oldest cake is a wedding cake baked in 1898 by a British pastry maker, and it holds the Guinness World Record as the oldest intact wedding cake. It was proudly displayed in the window of a family bakery in Basingstoke UK for more than 65 years.
When the bakery closed in 1964, the cake was moved to the attic. It remained there until 1995, when the cake was handed over to the Willis Museum of Basingstoke where it is currently on display.
The cake is still in one piece, but it has some damage: A crack on it's side is the result of vibrations from a bomb blast during World War II. The cake also now looks yellow, although that is because the white icing it was made with has been taken over by sugar seeping to the surface.
Most interestingly, tests have shown that the fruit cake behind the icing ornate is still moist! The daughter of the baker who made the cake donated it towards the end of her life because she feared someone might discover it in the attic and think she was dumped at the altar.
