From the kitchen of Grandma Barkwell (maiden name
Josephine Mackzo).  If you ask someone from the
Polish-American community of Binghamton what a Kolachki
is, they'll tell you it's a rolled cookie that contains poppy
seed, lekvar, nut or apricot filling.  Nuts seems to be the
most popular.  The other fillings are sold in the baking aisle
of grocery stores.
3/4 c milk
4 c flour
4 egg yolks (save the whites)
1 c butter
1 envelope yeast dissolved in a little bit of warm milk

Cut the butter into the flour.
Add remaining ingredients.
Work until incorporated.
It will be stiff for awhile.
Put in refrigerator for several hours.

Roll out small amounts of dough at a time.
Roll to 1/8" thickness.
Cut into 1 1/2" squares.
Spread 1/2 tsp filling over each square.
Roll up & place on cookie sheet.
Bake 15-20 minutes.

Nut filling:
1 1/2 lb ground walnuts
1 c sugar
1 Tbsp butter, melted
4 egg whites
Slowly heat on the stove so the sugar disolves.
If you use too much filling, it will ooze out the ends.
