However, the 33-year-old from Dunfermaline has changed his eating challenge to After Eight mints for the 2010 series.
Boyd failed to break the Ferrero Rocher world record at last year's auditions, only managing to eat four of the chocolates in a minute. Host Ant McPartlin easily beat him, swallowing five.
His 2009 challenge sparked several imitators, with Britain's Got More Talent host Stephen Mulhern hosting a competition to find someone who could break the Guinness World Record of seven Ferrero Rocher in under 60 seconds.
Britain's Got Talent returns on Saturday at 8pm on ITV1.
