This popular Polish dessert is a variation of the classic cremeschnitte, a treat known under different names in many central and eastern European countries. In its simplest form, kremówka couples vanilla-flavored pastry cream that is placed between two layers of thin and crisp puff pastry.
While it is usually dusted with a layer of powdered sugar, some variations adapt the cake with an additional layer of whipped cream. In Poland, kremówka is also known as Napoleonka, named after a similar French dessert consisting of three layers of puff pastry coated with pastry cream.
