The Keebler Company is an American cookie and former cracker manufacturer. Founded in 1853, it has produced numerous baked snacks. Keebler had marketed its brands such as Cheez-It (which have the Sunshine Biscuits brand), Chips Deluxe, Club Crackers, E.L. Fudge Cookies, Famous Amos, Fudge Shoppe Cookies, Murray cookies, Austin, Plantation, Vienna Fingers, Town House Crackers, Wheatables, Sandie's and Munch'Ems.
A Reddit user mentioned, "Munch ‘Ems were nothing but a hybrid between a potato chip and a cracker, and that basically sums up the concept of the salty snack. It was artificially flavored and gave you an extreme dry mouth."
