Ptasie mleczko

Ptasie mleczko (Polish: [ˈptaɕɛ ˈmlɛt͡ʂkɔ] ^ⓘ) or bird's milk is a confectionery originating in Poland as well as the name for a Soviet cake that was derived from the original Polish invention. It is a small, chocolate-covered bar with a soft marshmallow-like interior.

E. Wedel is one of the most recognized chocolate confectioneries in Poland, having exclusive rights for the name Ptasie mleczko. Its owner created the original "bird's milk" in 1936. Other confectionery producers also make similar candies named differently (e.g., Alpejskie mleczko, "Alpine milk"). Nonetheless, Ptasie mleczko is often used to refer to similar candies with vanilla, cream, lemon or chocolate flavour.

In Russia, ptichye moloko (птичье молоко) is both a popular candy and a famous soufflé cake derived from the Polish candy. The brand was introduced in the 1960s during the Soviet era, and continues to be used by companies operating the factories which produced these candies and cakes since that time. The confectionery is also produced in other post-Soviet states, such as Ukraine.
