The carrot cake presented to the duchess and husband Prince Charles read: 'Happy birthday ma'am.'
Twitter couldn't help laugh at the creative concoction.
The duchess celebrated her 71st birthday with a huge day of events during a Royal Tour of Cornwall alongside husband Prince Charles. The Duchess of Cornwall greeted locals at St Mary's and St Martin's in the Isles of Scilly and looked lovely in a floral gown.
Camilla was even gifted a a beautiful bouquet of flowers from a young boy, and excitedly petted a puppy.
