Toss first 7 ingredients together; mix in butter. Mix with your hands to form a dough. Add water if dough feels too dry. On a floured surface, roll out half the dough to 1/4-inch thickness. Cut with a 2 1/2-inch star-shaped cookie cutter and place on an ungreased baking sheet. Reroll scraps and repeat with the remaining dough. Bake at 375 degrees for 10 to 12 minutes. Remove to a rack to cool.
