Cheez-It crackers are an American snack food manufactured by the Kellogg Company. They are roughly 26 by 24 mm (1.0 by 0.95 inch) square-shaped crackers made with wheat flour, vegetable oil, sharp yellow cheese, salt, and spices. The color comes from oleoresin (a plant derivative) According to the United States Patent and Trademark Office trademark records, the first "Cheez-It" Cheese Crackers were sold by Green & Green Company of Dayton, Ohio in May of 1921. After the stock market crash, The Green & Green Company was acquired by The Sunshine Biscuit Company, founded in 1902 as the Loose-Wiles Biscuit Company. The Keebler Company acquired Sunshine in 1996, and Keebler was in turn acquired by Kellogg in 2001. Cheez-It crackers are still sold under the Sunshine label. So how do they pack that much cheese flavor in...chemicals, well that and magic of course. Maybe Peter Gossamer or Kirby VanBurch would know.
