First, prepare the flax egg by combining the flaxseed and warm water in a small bowl, stir and set aside. Peel and mash banana and baking powder together with a fork.
Add in milk, flax egg, and vanilla and stir.
Next add salt, oats, and cinnamon and stir. And then add flour and stir until just combined. Fold in chocolate chips.
Preheat waffle iron and let batter rest for 5 minutes.
Once iron is ready, spray generously with cooking spray (this is key for the batter not to stick) and cook according to instructions.
Serve with pure maple syrup and whatever toppings your heart desires.
Enjoy!
