Chocolate Mousse Brownie Dessert

Heat oven to 350°F (325°F for dark or nonstick pan). Grease bottom only of 9-inch square pan with shortening or cooking spray. Make brownie batter as directed on box. Spread in pan.

In 1-quart saucepan, heat 1/2 cup whipping cream and the chocolate chips over medium-low heat, stirring constantly, until chocolate is melted and mixture is smooth; cool 5 minutes.

In medium bowl, beat 2 eggs and the sugar with electric mixer on medium speed until foamy, about 1 minute. On low speed, beat in cream-chocolate mixture until blended. Pour evenly over batter.

Bake 30 to 34 minutes, or until topping is set and toothpick inserted in center comes out almost clean. Cool completely on cooling rack, about 2 hours. Refrigerate 1 hour or until chilled. Cut into 4 rows by 4 rows. Sprinkle cocoa on top and serve with whipped cream. Store loosely covered in refrigerator.
