1 cup confectioners sugar
3 cups unbleached all purpose flour, sifted
1/2 t salt
1/2 t vanilla extract
Blend butter and sugar in a mixer fitted with the paddle attachment. Sift flour and salt together and add it to the butter and sugar in a few additions. Add vanilla and blend well. Gather dough into ball and flatten slightly on waxed paper. Place in the refrigerator and chill 4-6 hours.
Roll dough to 5/8 inch thickness and use cookie cutters to cut desired shapes. Place on ungreased cookie sheets and refrigerate for 20 - 40 minutes before baking. Bake for 20 minutes, until just starting to color lightly - do not brown. Cool completely on racks before frosting.
