An ice cream cone, poke or cornet is a dry, cone-shaped pastry, usually made of a wafer similar in texture to a waffle, which enables ice cream to be held in the hand and eaten without a bowl or spoon. Various types of ice cream cones include wafer (or cake) cones, waffle cones, and sugar cones.
Many styles of cones are made, including pretzel cones and chocolate-coated cones. A variety of double wafer cone exists that allows two scoops of ice cream to be served side by side. Wafer cones are often made with a flat bottom instead of a pointed, conical shape, enabling the ice cream and "cone" to stand upright on a surface without support. These types of wafer cones are often branded as "cups".
