In a lagre mixing bowl, combine flours, oats, brown sugar and salt.
In another bowl, whisk milk, egg replacer mixture and oil.
Add wet ingredients to dry ingredients and whisk until all the ingredients are thoroughly moistened. Let the batter rest for 5~10 minutes.
Preheat the waffle iron and follow instructions. I pour about 1 cup of batter into the center of the bottom grid and then bake for about 4 minutes or until the waffle is brown.
Serve hot with maple syrup.
