Princess Diana was a huge fan of this Cadbury classic

To this day, Princess Diana's life and interests remain a topic of great interest to royal audiences. From the late princess's favorite beauty products, to her incomparable style, favorite dishes and more, everything still fascinates fans of the "People's Princess" around the world. In an interview with Bustle, former royal chef Darren McGrady, who cooked for the royal family for more than 15 years, revealed some little-known details about Princess Diana's daily life, including her favorite snacks.

Chef McGrady served Her Majesty the Queen at Buckingham Palace for 11 years before moving to Kensington Palace to cook for Princess Diana in 1993 following her split from Prince Charles. In an exclusive interview on behalf of British coffee retailer Coffee Friend, chef McGrady revealed that in addition to lychees, Princess Diana also "enjoyed" chocolate bars, with Cadbury Twirls being her favourite.

"That's her real weakness," Maddie revealed. "We had a small team at Kensington Palace and I would often drive her Mercedes and BMW to refuel. When driving back I would sometimes notice a lot of chocolate wrappers in the side compartment," he added.

The former royal chef also recalled that when Diana was asked about a chocolate bar wrapper found in her car, she would jokingly blame it on her two young sons, Princes William and Harry, They had been away from Ludgrove School for a few weeks. "They were her wrapping paper and she was kidding," Maddie explained.

He added that Princes William and Harry inherited their mother's love of sweets and have a special fondness for chocolate and banana desserts.

"The kids were all bananas, and they loved bananas," Maddie recalled. "Things like banana pie and chocolate ice cream are some of their favorite foods. William absolutely loves chocolate biscuit cake, which is also a favorite of the Queen. We do it all the time at Buckingham Palace," he added. Very sweet indeed.
