Kiev cake

Kyiv cake is a dessert cake produced in Kyiv, Ukraine since December 6, 1956 by the Karl Marx Confectionery Factory which is now a subsidiary of the Roshen corporation. It quickly gained popularity throughout the Soviet Union. The cake has emerged as a symbol of Kyiv, largely due to its brand name and packaging featuring the depiction of a horse chestnut leaf, which was present on the Coat of Arms of Kyiv during the Soviet era. The cake consists of two light layers of meringue with hazelnuts covered in a chocolate glaze, and filled with a buttercream-like filling.
