1Heat oven to 350°F. In medium bowl, beat butter, brown sugar, 1/2 teaspoon vanilla and egg with electric mixer on medium speed until smooth. On low speed, beat in flour, salt, cardamom and cinnamon. Refrigerate dough about 1 hour or until firm.
2Shape dough into 1-inch balls. On ungreased cookie sheets, place balls 2 inches apart. Gently press bottom of drinking glass onto dough to grease, then press into granulated sugar and onto dough balls to flatten to about 1 1/2 inches in diameter.
3Bake 7 to 9 minutes or until edges are just beginning to brown and centers of cookies are set. Immediately remove from cookie sheets to cooling racks. Cool 10 minutes.
4In small bowl, mix powdered sugar, 1 teaspoon vanilla and enough of the milk until glaze is smooth and thin enough to drizzle. Drizzle glaze over cookies; sprinkle with sugar crystals.
