HEAT oven to 325 degrees F. Mix brownie mix, 6 tablespoons melted butter and water in large bowl; beat 50 strokes with spoon (mixture will be thick). In small bowl, beat egg whites with electric mixer on high speed 1 to 2 minutes or until soft peaks form. Add to brownie mixture; beat with electric mixer on low speed just until blended, about 30 seconds (batter will appear lumpy).
