1      C             Whole-Wheat Flour
   1      C             All-Purpose Flour -- Unbleached
     1/2  C             Cocoa Powder
   1 1/2  C             Sugar
   2      Tsp           Baking Soda
     1/4  Tsp           Salt -- Optional
   1 1/2  C             Banana -- Very Ripe, Mash,
                        -- About 3 Lg
     1/2  C             Buttermilk -- Nonfat
   2                    Egg Whites
   1 1/2  Tsp           Vanilla Extract
                        Glaze:
   1 1/2  C             Confectioner's Sugar
   1      Tbsp          Cocoa Powder -- Plus
   1 1/2  Tsp           Cocoa Powder
   3      Tbsp          Skim Milk
   1      Tsp           Vanilla Extract
     1/4  C             Chopped Walnuts -- Plus
   2      Tbsp          Chopped Walnuts -- Optional
Combine the flours, cocoa, sugar, baking soda, and salt, if desired, and
stir to mix well.  Add the banana, buttermilk, egg whites,a nd vanilla
extract, and stir to mix well.
Coat a 9 x 13" pan with nonstick cooking spray.  Spread the batter evenly in
the pan.  Bake at 350 deg F for about 35 min., or just until a wooden
toothpick inserted in the center of the cake comes out clean.  Cool the cake
to room temp.
To make the glaze, combine the glaze ingredients in a small bowl.  If using
a microwa e oven, microwave the glaze, uncovered, at high power for 35
seconds, or until runny.  If using a conventional stove top, transfer the
glaze to a small saucepan and place over medium heat for 30 seconds,
stirring constantly.  Drizzle the glaze over the cake, and let harden before
cutting into squares and serving.
This is quick and really excellent tasting.
