Combine all ingredients except flour in large bowl. Beat at medium speed until creamy. Reduce speed to low; add flour. Beat until well mixed.
Divide dough in half. Wrap each half in plastic food wrap; flatten slightly. Refrigerate until firm (30 minutes or overnight).
Heat oven to 350°F Roll out dough on lightly floured surface, one-half at a time (keeping remaining dough refrigerated), to 1/8-inch thickness. Cut with 3-inch cookie cutters.
