Kate Middleton, Prince William's Wedding Cake Baker Shares Awkward Encounter With Queen Elizabeth II

Kate Middleton and Prince William will be celebrating their 10th wedding anniversary later this month and their wedding cake baker revisited the time they set up the cake for the royal couple's big day.

Fiona Cairns, who led the team behind the Duke and Duchess of Cambridge's three feet-tall fruit cake appeared on ITV's new documentary "The Day Will and Kate Got Married" and shared what happened when they transported the cake into the reception venue — Buckingham Palace, Queen Elizabeth II's royal residence in London.

To bring the cake inside the Picture Gallery in Buckingham Palace, the team had to remove a door. When Her Majesty visited them while they were putting the finishing touches on the dessert she made, they heard an unexpected remark about the team's work.

"I can remember her saying, 'I hear that you've been dismantling my house,'" Cairns was quoted by People as saying in the documentary. "And I said to her, 'Well, we had to take a door down from the room below for the trolley to go through with the cake.' But it was all put back so in the end, it was fine.”

In another interview in 2018 with Town & Country, Cairns said it was a huge privilege when they were considered to make the wedding cake for the future king and queen. In fact, it was "an enormous responsibility" for them right from the very beginning.

"As soon as we were commissioned, from the time of the phone call, I had sleepless nights," the pastry chef said. "We had to keep pinching ourselves. It's a very important part of the royal wedding, and it was the biggest, most important commission that we as a business had ever received."

Prince William and Middleton's wedding cake was a traditional fruitcake adorned with 900 leaf and floral touches and topped with the couple's cipher. It lasted beyond the wedding reception with pieces of the fruitcake served at their children Prince George, Princess Charlotte and Prince Louis' christening.

Prince William and Middleton's wedding at Westminster Abbey was followed by two Buckingham Palace receptions — the first was hosted by Queen Elizabeth II for 650 guests and the second gathering for 300 people was hosted by Prince William's father, Prince Charles. The bride and groom mingled with the visitors freely while keeping a watchful eye on the other with one observer saying they were "definitely a team."

"They're definitely a team," said Christopher Warren-Green, the music director of the London Chamber Orchestra that played at the Duke and Duchess of Cambridge's royal wedding. "They ask each other, 'Should we do so-and-so?' You can just see it."

Prince William and Middleton will be celebrating their 10th wedding anniversary on April 29.
