If you're going to quit your job to pursue your dream job of making cakes for a living, then writing your resignation letter on a cake is definitely the right move.

On his 31st birthday, Chris Holmes — now known to the public as "Mr. Cake" — decided it was time to quit his job as a Border Agency official at London's Stansted Airport to do something he's passionate about and would allow him to spend more time with this family. For Holmes, this meant pursuing a cake business called Mr. Cake and notifying his employers with actual icing on a cake.

Holmes' sweet resignation letter quickly went viral when his brother-in-law tweeted a picture of it to the world. Note the bottom of the cake has a nice plug for his business, so this is great marketing as well:

In an interview with Elodie Harper at Sawston's local news station ITV news, Holmes said that his deision "seemed like the obvious choice."

"... Having set up a cake company, I thought I would leave them with a memento that would be a nice way of remembering me. I had the idea six months ago so I've kept it to myself since then."

"I think [my boss] was pleasantly surprised, of all the resignations businesses get, I think that's probably a nice way for an employee to leave and I hope they enjoyed the cake as well as the resignation."

Holmes' employers told Harper that they wished him "all the best" in his new business venture.
