The cans of dessert exploded "like fireworks" after the a blaze broke out on his HGV.
The driver was unaware that his lorry, carrying 26 tonnes of Ambrosia custard and rice pudding to a local supermarket, was on fire and motorists were forced to flag him down.
He eventually stopped on the A382 in Chagford, Devon, and fled the truck seconds before 60,000 cans began exploding "like thousands of gunshots".
