Divide each dough into 2 portions. On work surface sprinkled generously with flour, shape each dough portion into 15-inch rope. Place 1 rope chocolate chip dough and 1 rope double chocolate chunk dough side by side. Cut both at the same time into 1/2-inch pieces; shape into about 24 balls so both kinds of dough are in each ball. Place 2 inches apart on ungreased cookie sheet. Repeat with other 2 ropes of dough.
