King cakes are usually baked for Mardi Gras, but the absolute king of king cakes showed up in September 2010 to raise funds for the Susan G. Komen Breast Cancer Foundation. Fashioned to wrap twice around the New Orleans Saints' Superdome, this enormous snake of a cake measured 5,300 feet in length and is believed to weigh 8,000 pounds. The folks at family-owned and -operated Haydel's Bakery baked for three days to get the cake to size. It took six hours to assemble it around the Superdome. There was no report on how much plastic wrap was used to cover the mile-long cake.
