1Heat oven to 350°F. Let dough stand at room temperature 10 minutes to soften.
2In large bowl, break up cookie dough. Add cooled chocolate and flour; stir with spoon or hands until well blended.
3Shape dough into 36 (1 1/4-inch) balls. Roll balls in sugar. Place balls 1 inch apart on ungreased cookie sheet.
4Bake 7 to 9 minutes or until edges are set. Immediately top each cookie with 1 candy, pressing down firmly so cookie cracks around edges. Cool 2 minutes; remove from cookie sheets to cooling racks. Cool completely, about 30 minutes.
