Roll half of dough to a 10- x 6-inch rectangle on a lightly floured surface. Cut into 12 rectangles, and place 2 inches apart on a lightly greased or parchment paper-lined baking sheet. Score each rectangle in the center crosswise with a knife. Gently press semisweet chocolate morsels, points down, into dough, forming domino dots. Repeat with remaining dough.
Bake at 325° for 10 to 15 minutes or until edges are golden. Slightly cool on baking sheets; remove to wire racks and cool completely.
