The Ding Dong is a chocolate cake produced and distributed in the United States by Hostess Brands and currently owned by private equity firms Apollo Global Management and Metropoulos & Co; it remains in production and distribution in Canada from Saputo Incorporated under the name King Don. Ding Dong production resumed in the United States on July 15, 2013 after an absence from American store shelves. It is round with a flat top and bottom, about three inches in diameter and a little more than an inch high, similar in shape to a hockey puck. A white creamy filling is injected into the center, and a thin coating of chocolate glaze covers the entire cake. The cake was originally wrapped in a square of thick aluminium foil, enabling it to be carried in lunches without melting the chocolate glaze.
