According to the Hostess website, Zingers are a cream-filled snack cake brand manufactured by Interstate Bakeries Corporation (IBC). Hostess Zingers are snack cakes with both icing and a cream filling. Three flavors are available: devil's food cake with chocolate icing, vanilla cake with vanilla icing and vanilla cake with raspberry icing topped with coconut flakes. The products are available packaged as three-cake packs and in larger family-sized multipacks. Zingers' popularity and ingredients probably preclude having to worry about an expiration date, however, this information is prominently displayed and easily located.
Look on the front of the family-size box in the top far right corner. The last day a store is allowed to sell this product is printed on the top right with the month and date, such as "JUL 21," for example.
Look on the front of the three-cake-size package in the bottom far right corner. The last day a store is allowed to sell this product is printed on the bottom right corner with the month and date, such as "APR 14," for example.
