Heat oven to 350°F.


Microwave chopped chocolate and cream in microwaveable bowl on HIGH 1-1/2 min. or until chocolate is melted and mixture is well blended, stirring every 30 sec. Cool 15 min., stirring occasionally.


Meanwhile, line 15x10x1-inch pan with foil; spray with cooking spray. Prepare brownie batter as directed on package; spread onto bottom of prepared pan.


Bake 10 to 12 min. or until toothpick inserted in center comes out with fudgy crumbs. (Do not overbake.) Top with marshmallows; bake 2 to 3 min. or until marshmallows are puffed and softened. Immediately top with wafers; press gently into marshmallow topping.


Spread chocolate sauce over dessert, completely covering wafers; sprinkle with nuts. Cool completely.
