Holmes’ brother-in-law posted a picture of the cake to his Twitter account. The message reads:
“Today is my 31st birthday, and having recently become a father I now realize how precious life is and how important it is to spend my time doing something that makes me, and other people, happy.
“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”
Holmes had worked at the Border Force as an immigration officer for the past four years.
As brother-in-law Stuart Jackson wrote in his Twitter photo caption: “So, my brother-in-law has resigned from his 9-to-5 job in spectacular fashion. Jerry Maguire meets Masterchef.”
The now-former employer has taken the resignation graciously.
"Chris handed in the cake, along with a more formal letter, yesterday,” Bill Form, Border Force assistant director at Stansted, told the BBC. "He leaves with our very best wishes and we wish him well for the future."
The picture of the cake resignation letter has gone viral since first being posted on Monday. For his part, Holmes says he has been "overwhelmed by the positive response" from the public.
