Kate Middleton Jokes About Prince William Being ‘Fussy’ About Brownies

Despite a somber occasion, Kate Middleton and Prince William were in good spirits while sharing some sweet treats.

The Prince and Princess of Wales, both 43, paid a visit to the National Federation of Women’s Institutes in London on Monday, Sept. 8, the third anniversary of Queen Elizabeth‘s death. The late monarch was an enthusiastic member of the WI for 80 years and served as its president from 2003 until her death.

During their visit, Prince William and Princess Kate chatted with WI members over some baked goods, like Campari cake and brownies, of which William is a particular fan.

“I know my brownies,” he said during the visit, as seen in a video shared on social media.

His wife noted, “William is very fussy about it,” to which he agreed.

The future king’s rule for a good brownie? “Never put nuts in a brownie,” he said.

Kate then quipped, “I had to learn the hard way,” drawing laughs from the group.

According to the Daily Mail, William was told by Hilary Fraser that he couldn’t join the WI “unless you can put on a skirt.”

He joked in response, “Well, for a chocolate brownie, Hilary, you never know what I’ll do.”

The Prince and Princess of Wales also shared some sweet stories about their children, Prince George, 12, Princess Charlotte, 10, and Prince Louis, 7, with the women. When asked if Louis is “a bit of a handful,” William admitted that appearances can be deceiving.

“He’s a character, but he’s a very good boy. He likes to wind his brother and sister up,” the prince said, according to the Daily Mail.

The proud father joked that Prince George only appears to be the more sensible one in public.

“When George is behind closed doors, it’s completely different. George just knows how to behave,” Prince William said with a smile.
