Add the flour, sugar, baking powder, baking soda and salt to a large mixing bowl and mix until fully incorporated. Set it aside.
Blend the spinach, banana, egg, coconut oil, vinegar and milk together until smooth.
Add the blended wet ingredients to the bowl of dry ingredients and gently mix until it just comes together. Do not over mix it. (A few lumps are fine!)
Heat a skillet over medium low-heat. Add a little coconut oil, then scoop the batter into the skillet. (I use 1/8 cup of batter for baby pancakes or 1/2 cup for adult sized pancakes.) Cook for about 2 minutes, or until a few bubbles start to form on the top of the pancake.
Flip the pancake over and cook for another 1-2 minutes, until fully cooked through.
Repeat until you’ve used all the batter. Serve immediately. Enjoy!
