Zingers are an American snack cake sold under both Dolly Madison and Hostess, snack food brands owned by Interstate Bakeries Corporation. Zingers are similar to Twinkies and come in devil's food, vanilla, and raspberry flavors. Chocolate and vanilla Zingers have a thick layer of icing on top with cream filling in the middle. Raspberry Zingers do not have icing on top but are instead covered in a mixture of shaved coconut and raspberry flavored frosting. A series of commercials for Zingers used the Peanuts characters, with Snoopy playing the part of the mysterious 'Zinger Zapper', the thrust of the ads featuring the other characters attempting to discover his true identity by tempting him with Zingers. Zingers later introduced the Ecto-Cooler flavored in conjunction with the release of The Real Ghost Busters cartoon series. It featured a vanilla filling topped with a thick orange flavored icing. The entire cake was colored green to match the character Slimer from the series.
