Karpatka

Karpatka is a traditional Polish cream pie with some sort of vanilla buttercream filling - aerated butter mixed with eggs beaten and steamed with sugar (krem russel), aerated butter mixed with crème pâtissière (according to Polish gastronomy textbooks made from whole eggs) or just thick milk kissel enriched with melted butter. Professionally it is made of one sheet of short pastry covered with a layer of choux pastry with a thin layer of marmalade and a thick layer of cream in between. Nevertheless, the version with two layers of choux pastry is popular. The cake is cut into squares or rectangles and dusted with icing sugar.
