1 3/4 cup sugar
3/4 cup unsweetened cocoa powder
1/2 cup all-purpose flour
1/2 cup whole wheat flour
7 egg whites
2 (4-ounce) jars of baby food prunes or 2/3 cup unsweetened applesauce
1/4 cup buttermilk
2 teaspoons vanilla
2/3 cup chopped walnuts
Preheat the oven to 350ºF. Lightly spray a 13x9x2 baking pan with no-stick spray. Set the pan aside. In a large bowl, stir together the sugar, cocoa, all-purpose flour, whole wheat flour and baking powder. Set the flour misture aside. In another large bowl, beat the egg whites until foamy. Slowly stir in the prunes or applesauce, buttermilk and vanilla. Add the egg mixture to the flour mixture and beat with an electric mixture until thoroughly combined. Fold in the walnuts. Transfer the batter to the prepared pan. Bake about 30 minutes or until the brownies just begin to pull away from the sides of the pan (do not overbake). Cool completely on a wire rack before cutting into bars.
