Shaker-churek is a traditional cookie originating from Azerbaijan. The cookies are usually made with a combination of flour, icing sugar, eggs, butter, and vanilla extract. The butter is mixed with icing sugar and then with vanilla, egg yolks and whites, and flour.
The dough is left to chill in the fridge for about an hour. Once firm, it’s formed into small balls that are placed on a baking sheet. An indentation is made in each dough ball, and they’re brushed with egg yolks. The cookies are baked in the oven until golden brown, cooled, and then dusted with icing sugar before consumption.
