Just Whites Viennese Brownies

Just Whites is a 100 percent all-natural, powdered egg white product. It requires no refrigeration and has a shelf life of up to five years. It is available in an 8-ounce canister that is equivalent to four and a quarter dozen egg whites. To use, just add warm water to the appropriate amount of Just Whites for real liquid egg white.

3/4 cup granulated sugar
1/3 cup vegetable oil
2 teaspoons vanilla extract
1 tablespoon plus 1 teaspoon Just Whites
1/3 cup warm water
3/4 cup flour
1/3 cup unsweetened cocoa
1/4 teaspoon baking powder
1/8 teaspoon salt
2 teaspoons sifted confectioners' sugar 

Preheat oven to 350 degrees F.

Combine first three ingredients in a large mixing bowl and blend well.

In a separate bowl whisk Just Whites with warm water; let stand 2 1/2 minutes, then add to first three ingredients.

Combine flour, cocoa, baking powder and salt in separate bowl. Add to sugar mixture, stirring until just moist.

Pour batter into an 8-inch square baking pan coated with vegetable cooking spray. Bake at 350 degrees F for 25 minutes, or until a wooden pick comes out clean. Let stand to cool and sprinkle with sugar.
