Take dry ingredients (all purpose flour, whole wheat flour, sugar, salt and baking powder) in a bowl. Mix it well using whisk or just shift it.
Make a well in the middle. add water, oil and vanilla extract.
Mix it using wire whisk till incorporated. Make sure there are no lumps in the batter.
Making eggless waffles:
While you are making batter, preheat the waffle iron.
Pour the batter in the pre-heated waffle iron. Read your waffle maker’s manual and pour required batter as directed. If your waffle maker needs then grease it with cooking oil spray before pouring the batter. Mine did not require.
Cook it as per your waffle maker’s direction + few more minutes. Why? Always keep in mind that, waffles made without eggs takes more time to cook then one with eggs.
For example, my waffle maker takes 5 minutes for normal waffle. So I usually cook any eggless or vegan waffles for 7 minutes.
Eggless waffles always need some more time to crisp up.
