1 1/2 cup Powdered sugar (sifted)
1 cup Butter or margarine (softened)
1 tsp Vanilla extract
2 1/2 cups All purpose flour
1 tsp Baking soda
Mix powdered sugar thoroughly with butter, the egg, and vanilla extract. Blend in the flour and baking soda. Form dough into ball and wrap in plastic wrap. Chill in freezer for several hours or overnight in refrigerator. When ready to bake, preheat the oven to 375 degrees F. Divide dough into three equal portions. Refrigerate any dough you are not working with. On a floured surface, roll out dough to 1/8″ or 1/4″ thickness. Cut with cookie cutters and place on lightly greased baking or cookie sheets. Decorate with colored sugar if desired, before baking. Bake 1/8″ thick cookies for 6-8 minutes, bake 1/4″ thick cookies for 8-10 minutes. Cookies are done baking when the tops look dry and edges begin to turn light golden brown. Avoid overbaking. Remove cookies from baking sheets immediately and allow to cool on wire racks. Frost with cookie frosting if desired.
