Frozen Waffles were invented in San José, California in 1953 by the three Dorsa brothers. They eventually settled on the name Eggo waffles for their invention because of its eggy taste. While the Eggo waffle company was eventually sold to Kellogg, the Eggo factory continues on in San Jose near Julian Street and Hwy 101.
