1. To prepare cookies, weigh or lightly spoon flour into dry measuring cups; level with a knife. Combine flour and next 7 ingredients in a large bowl, stirring with a whisk.
2. Place granulated sugar and butter in a large bowl; beat with a mixer at medium speed until smooth and well blended. Add molasses and egg; beat until well blended. Stir flour mixture into granulated sugar mixture until well blended. Divide dough in half; shape each dough portion into a flat disk. Wrap dough portions separately in plastic wrap; chill 1 hour or until firm.
3. Preheat oven to 350°.
4. Remove 1 dough portion from refrigerator; remove plastic wrap. Roll dough to a 1/8-inch thickness on a floured surface. Cut with a 3-inch boy or girl cookie cutter. Place cookies 1/2 inch apart on parchment paperlined baking sheets. Repeat procedure with remaining dough portion. Bake at 350° for 11 minutes or until edges of cookies are lightly browned. Remove from pans; cool completely on wire racks.
5. To prepare decorations, combine powdered sugar and milk, stirring until smooth. Spoon mixture into a heavy-duty zip-top plastic bag. Snip a tiny hole in 1 corner of bag. Pipe onto cookies. Decorate as desired with sugar sprinkles.
