Add the oatmeal to a blender and shred until you obtain a fine powder to make oatmeal flour. Then, mix the powders well (Matcha, Baking Soda and Oatmeal flour). On a different recipient, mix the moist ingredients (eggs, milk, apple vinegar and vanilla).
Crush half a banana (ripe banana) and mix it with the moist ingredients. After that, mix the moist ingredients with the powders until fully integrated (do not over-mix to prevent from hardening).
Preheat a pan with ghee, butter or coconut oil. Pour the mix little by little and turn it when you see bubbles and the edges are golden.
