Granny's Old-Fashioned Sugar Cookies

These cookies have been a hit with my family and friends for about 40 year.

3 cups self-rising flour
1 1/2 cups sugar
1 cup shortening
2 large eggs
4 tablespoons milk
1 tablespoon vanilla

Mix ingredients, form dough into a log, wrap in wax paper, chill, cut into quarter inch thick slices, place on an un-greased cookie sheet, bake in pre-heated 350 to 375 degree oven for about 7-9 minutes, cool, frost with confectioners sugar and water or milk mixture. Then sprinkle with red or green sugar and enjoy. The dough may also be cut into shapes!
The original recipe for these cookies came from the pages of an old cook book, a wedding gift in 1969. I changed it a bit over the years. Still I'd like to thank Mrs Kenneth G Mang of Trenton, NJ, the inspiration for these cookies. She entered her original recipe in the North Central Missouri State Fair and won a Blue Ribbon. Thank you Mrs Mang.
