1. Preheat the waffle iron according to the manufacturer's instructions.
2. In a bowl sift together flour, baking powder, salt, and cinnamon. Set aside.
3. In a second bowl use whisk (I use small from the electric mixer) to beat together the egg yolks and sugar until sugar is completely dissolved and eggs have turned a pale yellow.
4. Add oil, and milk to the eggs and whisk to combine very well. Combine the egg-milk mixture with the flour mixture and whisk just until well blended. Do not over mix.
5. In the third bowl, beat the egg whites with an electric mixer until soft peaks form, few minutes or so.
6. Gently fold egg whites into the waffle batter.
7. Add finely chopped or shredded apple in the mixture and fold again.
8. Lightly brush butter on the waffle iron and pour enough batter in iron to just cover waffle grid, about 1/2 cup, of course, this depends on the size of your waffle maker.
9. Close and cook as per manufacturer's instructions -until golden brown.

Apple Syrup

1. In the sauce or frying pan add butter and coat it well over the medium-high heat.
2. Add chopped apples, and saute apples for about 3-4 minutes turning them so they could get a nice color on all sides.
3. Add Maple Syrup and cinnamon. Cook for a couple of minutes or until the sauce is thick and all diced apples are coated well with the sauce.
4. Drizzle over the waffles and scoop apples and use as a topping. You can also add nuts. I used almonds, but you can add walnuts or hazelnuts.
