Grate and dab the zucchini between paper towels to remove excess moisture.
(You can use a food processor to grate zucchini)
Chop the walnuts and spray two 9" x 5" pans with non-stick spray.
Beat together the eggs substitutes first and set aside for 5 minutes. Add the unsweetened applesauce, vanilla, milk and sugar.
In a separate bowl, combine the flour, salt, baking soda, baking powder, cinnamon, and cocoa. Make a well in the dry ingredients, pour in the wet ingredients, and mix together. Stir in the zucchini and chocolate chips.
Pour the batter into the prepared pans. Divide the 1 cup of walnuts between both pans and pat into batter. Sprinkle with 1/4 cup of dark chocolate chips for each pan and press into batter.
Bake at 350 degrees for 60 minutes. Cool for about 20 minutes before removing from the pan.
