Oven 160ºC Mix butter and sugar until creamy. Add sifted dry ingredients. Chill until easy to handle. Roll out to 1 cm thickness on lightly-floured board or wax paper.
Cut into desired shapes (I have a bird cutter and Christmas tree). Bake on ungreased sheet at 160ºC for 10 to 15 minutes. Cookies may be sprinkled with colored sugars before baking, if desired.
