Make a dough like for a yeast cake. When the dough "rises", roll it out with a rolling pin for the thickness of an inch, cut out circles of 3-4" in diameter, place them on a cookie sheet and leave covered in a warm place. When they "rise", make a hole (with your thumb) and fill it with whatever filling you want: poppy seed, cheese, jelly. Brush Kolaczek with mixed egg and place it in the 350F oven for 25-30 minutes.
