While Guinness World Records does not have an official category for most pancakes eaten in one day, Australian Hayden Wilson unofficially made his mark by eating 80 pancakes in just over 17 minutes. The challenge took place on International Pancake Day 2013, according to the Huffington Post.
Guinness World Records recognizes accomplishments in many other pancake categories, from the most people flipping pancakes at one time to the tallest stack of pancakes ever. The International Federation of Competitive Eating maintains a list of current record-holders in the competitive eating field. Currently, they list Patrick Bertoletti as holding the record for eating the most 3.25-oz pancakes in 10 minutes. He managed to eat 50 in that time frame in September of 2012.
