This is a family recipe. Around Christmas and Easter, I usually think "oh, we should make Kolachkies, or Moctobabucta."
Kolachkies are a bit more complex to make than, say, coffee cake. But the unique taste of these pastries - which can be filled with absolutely anything - is definitely worth it!
Scald your cup of milk on the stove. You want to get the milk to froth, but not boil. Once the milk is frothy, take it off the heat and let it cool a bit.
Dissolve yeast in lukewarm water. Once the milk has cooled, add the yeast mixture to the scalded milk.
Cream butter, sugar, and salt in a small bowl.
Add 1 1/2 cups flour to the yeast / milk mixture. Mix well.
Add the sugar and butter mixture, plus one egg, to the flour and yeast mixture. Beat well. Gradually add the remaining flour until the dough becomes smooth enough to handle.
Knead your dough until it is smooth and elastic. Place it in a greased bowl, covered, in a warm place. Let it rise until doubled.
Place the dough on a warm floured board and cut into 2 1/2 inch squares, 1/4 inch thick. Put a spoonful of filling in the center of each.
Place your kolachkies 2 inches apart on a cookie sheet. Let them rise until doubled (about 45 minutes).
