Low Fat Cream Cheese Brownies

Preheat oven to 350 degrees F. Coat bottom of a 13- x 9-inch baking pan with cooking spray.

For Batter: Place butter in a large bowl. Beat with a mixer at medium speed until fluffy. Add sugar and 1 teaspoon vanilla. Beat until well blended (about 5 minutes). Add egg white and egg, 1 at a time, beating well after each addition.

Add cocoa and fat-free milk. Beat well (mixture will appear curdled).

Lightly spoon flour into dry measuring cups. Level with a knife. Combine flour, baking powder, and salt. Stir with a whisk. Add to cocoa mixture. Beat at low speed just until blended. Spoon batter into prepared pan.

For Topping: Place cream cheese in a large bowl. Beat with a mixer at medium speed until smooth. Gradually add cornstarch and remaining ingredients. Beat until smooth.
