In another bowl, cream butter till it is pale yellow and fluffy. Gradually beat in sugar and spices, then egg. And finally, gradually beat in flour.
Knead dough on floured surface a few times. Divide it into 3 pieces and roll each piece to 1/8" thickness. Cut with cookie cutters and place onto ungreased (or parchment-lined) baking sheet. Bake until edges are golden, about 10-12 minutes. Cool on wire rack.
