Recipe - Kifle Cookies

Kifle (Polish Cookie Recipe)
My Mom and I would make these every year for Christmas. I couldn't get enough of these cookies. You can use a wide variety of fillings for these cookies... My Mom and I liked Poppy Seed and Nut fillings the best.

INGREDIENTS
1 lb. butter
6 c. flour, unsifted
1 c. sour cream, 8 oz.
12 egg yolks
Few grains salt


FILLING: Baker brand dessert fillings


1. Cut shortening into flour until mixture seems crumbly.
2. Beat egg yolks slightly and add to flour-shortening mixture 
3. Add sour cream and mix this into flour and shortening thoroughly, making a dough.
4. Divide the dough in half and store it overnight in the refrigerator.

5. Next day take each dough ball and roll out on a floured board, making them thin.
6. Cut into 2"x2" squares, using as much of the dough as possible. (re-ball edges of dough and repeat steps 5 & 6 as needed)
7. Spread 1 teaspoon filling in the center of each square. Fold opposite corners of the dough squares into the middle.
8. Bake in 350 degree oven for 12 minutes until straw colored.
9. Cool, then sift confectioners' sugar over all the kifles. (OPTIONAL)
