SOUTHGATE, Mich. —  A Detroit area restaurant owner believes he broke the Guiness World Record for "largest hamburger commercially available."

After 12 hours of preparation and baking, the 134-pound burger emerged at Mallie's Sports Bar and Grill on Saturday.

The Detroit News and the Detroit Free Press report the "Absolutely Ridiculous Burger" made with beef, bacon and cheese was delivered on a 50-pound bun. It sells for $350. Orders require 24 hours notice.

Flipping the burger required three men using two steel sheets.

Owner Steve Mallie tells The News he wanted to show he has the biggest and best burgers.

Mallie's unofficial record outweighs the 123-pound burger made last year by Denny's Beer Barrel Pub, of Clearfield, Pa. Authenticating Mallie's claim could take a few weeks.
