In a big mixing bowl add in the flour, cornstarch, salt, 2 tbsp sugar & baking powder, Mix Well.
For the Wet ingredients ( at this stage it's best to turn on the waffle maker)
Separate the egg whites from the egg yolk.
In a separate mixing bowl add in the egg yolk, vanilla flavoring & oil.
In a separate mixing bowl add in the egg whites with the 1/4 Cup of Sugar and whip them together with a electric hand mixer or whip it up by hand, until it forms a stiff peak, (it usually takes me 3-6 minutes with the electric hand mixer but it would probably take much longer by hand)
Mix in the Wet ingredients to the dry ingredients, be very careful not to over mix, (I would add in the chocolates and nuts at this stage) and fold in the Egg white merengue in the batter, again don't over mix just 2-3 rotation.
Oil or spray the waffle maker, make sure the waffle maker is now ready and hot, add in the batter and wait (mine takes about 6 min to cook).
