Method:
Preheat oven to 350°F. Lightly oil or spray a 9-inch springform pan or 9-inch round cake pan; set aside. Lightly heat soy milk in a small pot, then add coffee substitute; set aside. In a large mixing bowl, cream oil with applesauce and sugar, then add eggs and beat well. Add vanilla and soy milk-coffee mixture. Set aside 2 tablespoons of the ground walnuts for garnish. Mix remaining walnuts, flours, baking powder and salt together in a bowl, then add to applesauce mixture and beat well. Pour batter into prepared pan and bake for 30 minutes, or until done. Cool on a rack. Garnish cake with reserved walnuts and a dusting of powdered sugar, if desired.
