In a small bowl, mix flour, cinnamon, baking soda, baking powder, and salt.
In a medium bowl, beat egg and egg white; add sugar and oil and beat until well blended.
Stir in vanilla and the flour mixture. The batter will be thick.
Toss in the chopped apple and walnuts and give it a good stir. Now you’re ready to waffle it.
Preheat your waffle iron and coat it lightly with oil.
Pour some batter onto the hot iron, close the lid, and bake until done.
Drizzle with a little melted butter and this bread will simply melt in your mouth.
This may easily become your favorite way to make quick bread!
