Hedgehog slice

A hedgehog slice is an uncooked flat, square or bar-shaped chocolate snack/ dessert, similar to a fudgey chocolate brownie but with alternating lighter and darker areas. The darker areas are chocolate flavoured. The lighter areas are crushed biscuit,[1] rice puffs, or similar. Nuts may also be added.[1] It usually has a topping of chocolate icing on which may be sprinkled coconut, hundreds and thousands, or other kinds of sprinkles (e.g. chocolate or coffee flavoured, etc.).

The dish goes by a variety of names. In German it's called Kalter Hund (cold dog), Kalte Schnauze (cold snout) or Kellerkuchen (cellar cake). In some languages it's named after its appearance, such as Swedish radiokaka (named for both its resemblance to old-time radios and its ability to be eaten soundlessly so as to not disturb radio broadcasts), Turkish Mozaik Pastası or Greek Mosaico. The Danish kiksekage and Serbo-Croatian keks torta simply mean biscuit cake. The Dutch name Arretjescake comes from a promotional recipe book published by Calvé and is named after its mascot character,[2] while the Norwegian Delfiakake refers to the Delfia deep-frying fat mentioned in this recipe.

The dish is derived from chocolate salami which was invented in the beginning of the twentieth century and which in turn traces its heritage to various kinds of fake sausage confectionery without chocolate from the start of the nineteenth century.
