Use an electric mixer to cream butter and sugar until fluffy. Beat in eggs and vanilla.
Add flour mixture; mix on low speed until thoroughly combined. Divide dough in half; wrap in plastic. Chill at least 1 hour.
Heat oven to 350 degrees. On a floured surface, roll dough to 1/8 inch thick. Cut into desired shapes. Transfer to ungreased baking sheets; refrigerate until firm, 15 minutes. Bake for 8 to 10 minutes, until crisp but not darkened. Cool on wire racks; decorate as desired.
