A highly rated recipe for Polish kolache from Epicurious calls for a dough made from flour, cream cheese, butter and sugar. Poppy seed paste or fruit jam are suitable fillings for Polish kolache.
To prepare the dough for Polish kolache, place 6 ounces of softened cream cheese, 2 sticks of softened butter and 1 tablespoon of granulated sugar in a mixing bowl. Switch an electric mixer to the medium-speed setting, and beat the ingredients for approximately two minutes, or until they are light and fluffy. Adjust the speed to the low setting, and progressively incorporate 2 1/2 cups of all-purpose flour to form a sticky, flexible dough. Divide the dough into two thick pieces, and protect each piece with plastic wrap before chilling them in the refrigerator for one hour, or until they are firm.
Roll out each piece of dough onto a lightly floured surface to make a 1/8-inch-thick rectangle. Cut out squares that measure 2 1/2 inches, and add 1 teaspoon of poppy seed paste or fruit jam onto the middle of each square. Pinch the opposing corners of each square to create the appearance of a half-opened parcel, and arrange the parcels on greased cookie sheets. Bake the kolache at 350 F for 12 minutes, or until they develop a golden hue. Allow them to cool just slightly before decorating them with a sprinkling of powdered sugar.
