The wuzetka is a pastry cake cut into squares: two layers of chocolate sponge cake with a thick layer of whipped cream in the middle and a chocolate glaze on top. Many bakeries add a bit of cream and a cherry on top. Some recipes include a thin layer of fruit jam beneath the cream.
The cake appeared in Warsaw in the late 1940s. The most widely accepted explanation for the name is the Trasa W-Z, the East–West avenue (Wschód–Zachód) inaugurated on July 22, 1949, one of the first major projects in the city’s post–World War II reconstruction. According to this version, the bakery that began selling the cake stood next to the avenue. Others say the name comes from a bakery acronym; the exact origin is not documented.
The wuzetka became one of the best-known sweets in Warsaw’s bakeries in the second half of the 20th century and remains in the display cases of the city’s traditional shops. The cake is also listed on Poland’s Traditional Products List, in the Masovia entry.
