One baker resigned from his job in the sweetest of ways. Chris Holmes, a former immigration officer for Border Force at Stansted Airport in the U.K., resigned Monday with a perfectly written letter on a 12-inch-by-12-inch size sheet cake.

Known as Mr. Cake, Holmes, 31, had worked at the airport for four years while running his cake business on the side. Baking on evenings and weekends, his business had been gradually picking up since he started it three years ago. After the birth of his 5-week-old son, Ben, Holmes decided it was time to set an example for his son and pursue his passion full- time.

"If he hears about this when he's older, I think it'd be nice for him to know if you have a dream even if it seems unrealistic … if he's got the confidence to go out and take a risk to take the risk," Holmes told ABC News.

He prepared a spiced-carrot-and-orange buttercream "passion cake" and spent several hours covering and writing the letters in icing. The cake was such a secret, his wife, Emma, didn't even know about the plan until 24 hours before.

"I think she thought it was a nice idea," he said.

Before presenting it to his employer, Holmes' brother-in-law, Stuart Jackson, tweeted out a photo of cake.

"So, my brother-in-law has resigned from his nine-to-five job in spectacular fashion. Jerry Maguire meets Masterchef," Jackson tweeted. The photo also went viral on Reddit.

"Today is my 31st birthday, and having recently become a father, I now realise how precious life is and how important it is to spend my time doing something that makes me, and other people, happy," the letter read.

"For that reason I hereby give notice of my resignation, in order that I may devote my time and energy to my family, and to my cake business, which has grown steadily over the past few years."

"I wish the organisation and my colleagues the best for the future and I remind you that, if you enjoy this cake, you can order more at www.mrcake.co.uk." It was followed by his signature and nickname.

Since then, Holmes has been bombarded with interview requests and orders. He's even had a request for the famous resignation cake, which he said would cost about $150 to $230.
