Now, British amateur baker Lara Mason has taken it one step further and created a life-sized replica of the couple out of sponge cake, which is decorated with chocolate, ganache, and buttercream.
The cake was sponsored by Cake International, a cake competition that is held in the UK and celebrating its 25th anniversary this year.
"We wanted to combine the two special occasions and make something epic," Mason told Business Insider. The cake will be on display at the show in November and is currently being stored at Mason's studio in England.
"The cake is wrapped in sugarpaste so is airtight," she said. "This will keep it in good condition as long as it doesn’t get too hot!"
Sadly, this cake was only ever intended to be artwork, and it won't be eaten.
"I imagine after three days of people taking selfies, it might be a little worse for wear," Mason said.
The cake is modelled off of a photograph that was taken of the couple when they announced their engagement in November.
It took Mason 250 hours over six weeks to create the cake.
She told Business Insider the cake is made of around 15kg of eggs, 15kg of sugar, 15kg of flour, 15kg of butter, 50kg of icing, 20kg of modelling chocolate, 20kg of ganache, and 15kg of buttercream.
Mason was sponsored to make the cake. But, she told Business Insider, that it would cost around $4,000 (just shy of R50,000) to buy the ingredients and tools needed to make the cake.
The sponge was made by a company that sponsors Mason. She then put the structure together and decorated the cake.
Mason said she didn't do a practice run. "I just went for it!" she told Business Insider. A heatwave in the UK caused Harry's face to melt, which meant she had to remake it. "I actually think it turned out better the second time around so I guess we can call the first head my practice go," she said.
The royal wedding takes place at St George's Chapel, Windsor Castle on Saturday, May 19. It will begin at midday. More than 2,000 members of the public have been invited into the grounds of Windsor Castle to watch the couple and their guests arrive, and millions of adoring fans are expected to tune in to watch it live on television.
