John Boa, a Gaelic singer and student, fought off competition from 17 other challengers to take the top spot in a hotly contested final at Carrbridge, Inverness-shire.
Mr Boa, a student at Scotland's Gaelic College, Sabhal Mor Ostaig in Skye, said he was delighted to regain the main title at the World Porridge Making Championships.
He was previously champion in 2011, and the "people's choice" winner last year. The main 2012 competition was won by Benedict Horsburgh, originally from London, now living in Germany.
Mr Boa said: "All I can say is that practice makes perfect. I am absolutely delighted to win, and I'm sure that I'll get a great reception from fellow students and staff at the college when I go back to Skye."
The prize is given for the best traditional porridge using oatmeal, water and salt. Mr Boa's secret was to use medium oatmeal, Carrbridge tap water and ordinary kitchen salt Nick Barnard was crowned speciality champion for his recipe for fruity date porridge, using dried apricot, dates, apple and cinnamon.
