Despite the name of its best-selling product, Chattanooga Bakery is no pie-in-the-sky outfit. It is the one and only maker of the MoonPie, a four-inch-round sandwich cookie made of marshmallow fluff layered between graham crackers and coated with chocolate. In addition to the original iteration, MoonPies are available in double-decker and mini versions -- and with banana or vanilla coating. Its most recent variation is the crispy-shelled MoonPie Crunch, which comes with mint or peanut butter filling. The company also makes pecan and coconut pie snacks under the LookOut! name. Chattanooga's treats are sold nationwide at food retailers, mass merchandisers, convenience stores, and through vending machines.
