The reason why seven-year-old cake was served at Prince Louis' Christening

Prince Louis was christened on Monday, surrounded by his close family and some of his parents' friends, who were chosen to be his godparents.

The youngest of Kate and William's brood was peacefully asleep both when going in and out of The Chapel Royal, at St James’s Palace in London, while his brother and sister also behaved in a very polite manner and greeted guests as they came in, all while never letting go of dad William's hand.

The ceremony was an intimate affair, with about twenty guests invited to attend, including grandfather Prince Charles and uncle and auntie Prince Harry and Meghan Markle.

As they didn't have many guests, we're guessing the budget was kept low and it turns out they didn't even have to splash out on money for the cake.

After the celebration, the small group of guests headed to Clarence House for a private tea and they were served a tier of cake that was made for Kate and William's wedding.

A tweet from Kensington Palace official Twitter account read: 'One of the three top tiers of The Duke and Duchess of Cambridge's eight-tier wedding cake will be used for the Christening cake.'

But while serving seven-year-old cake could funnily be mistaken as a way to keep costs low, it's actually done for a very sweet reason.

It's tradition for couples to keep some of their wedding cake - which is usually fruit cake - and serve it each time a child of the couple is christened, as the Cambridges have also done the same for their first child, Prince George, and their second, Princess Charlotte.

Kate and William's wedding cake was designed by Fiona Cairns in April 2011, and consisted of 17 individual fruit cakes and had eight tiers.

The impressive showstopper was decorated with roughly 900 flowers and leaves using cream and white icing, and the garlands around the middle of the cake were chosen to match the details of the room where the cake was displayed for the wedding, the Picture Gallery in Buckingham Palace.

With this impressive baking masterpiece, we think Prince Louis could have done a lot worse...
