Bake 10 to 12 min. or until lightly browned. Meanwhile, microwave caramels and milk in microwaveable bowl on HIGH 3 to 3-1/2 min. or until caramels are completely melted and sauce is well blended, stirring after each minute.

Microwave reserved chopped chocolate in microwaveable bowl 30 sec. to 1 min. or until completely melted, stirring every 30 sec.; drizzle over dessert. Let stand until chocolate is firm. Use foil handles to lift dessert from pan before cutting into bars.
