Heat oven to 350°F. Line cookie sheet with parchment paper.
With fingers, press each of 6 of the cookie dough rounds into 2 1/2-inch circles (return remaining 6 cookie dough rounds to refrigerator).
Place 1 candy bar in center of each cookie dough circle. Wrap dough circles around candy bars, leaving a little of the candy bar exposed on the top. Place at least 2 inches apart on cookie sheet.
Bake 13 to 15 minutes or until edges are golden brown. Cool 2 to 3 minutes; remove from cookie sheet to cooling rack. Place clean sheet of parchment paper on cookie sheet; repeat with remaining 6 cookie dough rounds.
