Place dough on lightly floured surface; knead 5 min. or until smooth and elastic. Shape into ball. Place in bowl sprayed with cooking spray; turn. Cover tightly with plastic wrap. Let rise in warm place 1 to 2 hours or until doubled in volume. Meanwhile, combine chopped chocolate, cinnamon and remaining sugar.

Punch down dough; place on floured surface. Roll out to 16-inch square. Reserve 1/4 cup chocolate mixture; sprinkle dough with remaining chocolate mixture to within 1 inch of edges.
