The Duke and Duchess of Cambridge's wedding day was a grand affair and their incredible eight-tiered fruit cake was equally magnificent.
Leicestershire baker Fiona Cairns created the confectionery masterpiece, which took five weeks to make and was covered in cream and intricate white icing and decorated with up to 900 delicate sugar-paste flowers!
While much of the impressive cake was eaten at the couple's wedding reception, William and Kate decided to save the top two tiers for future use – and the reason is so sweet.
Did you know that the Cambridges' wedding cake was served at all three of their children's christenings?!

There were up to 900 individually iced flowers and leaves of 17 different varieties decorated on the cake.
"A garland design around the middle of the cake matched the architectural garlands decorated around the top of the Picture Gallery in Buckingham Palace, the room in which the cake was displayed during the wedding."
