1/3 cup butter
2/3 cup sugar
1/3 cup milk
1/2 cup flour
1 teaspoon baking powder
1 teaspoon cinnamon
Cream the butter and sugar together. Sift the dry ingredients and add alternately with the milk, using more flour if necessary to make a stiff dough. Roll on a floured board and cut in 2 inch squares. Bake on greased cookie sheets at 350-F about 10 minutes. Source: Pennsylvania Dutch Cook Book - Fine Old Recipes, Culinary Arts Press, 1936.
