Mix all dry ingredients- oat flour through baking soda in a large bowl.
In a small bowl mix wet ingredients- buttermilk through melted coconut butter. Stir well with a whisk.
Pour wet ingredients into dry ingredients and whisk until few lumps remain (it's ok to have some).
White batter rests, preheat griddle to medium heat and spray with cooking spray.
Using a 1/4 cup measure, scoop out some batter onto grilled. Cook for ~3 minutes or until underside is lightly browned, flip and cook another 2 minutes. Serve with pure maple syrup.
