In a large bowl, prepare flax egg by combining water and flaxseed and letting it rest for 5 minutes to achieve an “eggy” texture.
Add the maple syrup, applesauce, oil, brown sugar, baking powder, salt and cinnamon and whisk. Add almond milk and stir once more.
Next add flour and oat flour and whisk gently until just combined. Let batter rest while preheating your waffle iron, preferably to a high “crispy” setting. (I like mine crispy)
Once preheated, generously spray the waffle iron with non-stick cooking spray and spoon about 1/2 cup of the batter onto the center of the iron and cook according to manufacturer’s instructions.
Once done, place on a cooling rack briefly to let steam roll off and crisp up a bit. Then transfer to serving plates in a 200-degree oven. Serve warm with maple syrup and whatever toppings you wish.
