Blend all the ingredients in a blender for a short amount of time (20-30 secs depending on your blender strength). If you don't have a blender then whisk together the dry ingredients in one bowl (oat flour, baking powder, cinnamon). Whisk together the wet ingredients (mashed banana, milk and eggs) Fold dry mixture into wet mixture but don't overmix.
Heat a medium skillet on high heat and add a teaspoon of coconut oil. Once heated, bring the heat down to medium, take a tablespoon of batter and portion out 4 pancakes across the skillet and let them cook for about 3 minutes until the sides are golden and have firmed.
Flip them (they should flip super easily) and cook for another 2 minutes.
Serve with some nut butter, fruit, yogurt, syrup.
Notes
if batter too runny add a tbps more oat flour
if batter too thick add tablespoon by tablespoon of milk
keep the gluten- free - make sure you buy gluten-free oats or gluten-free oat flour
make them vegan by using a flax egg or chia egg (for 1 egg mix a tablespoon of flaxseeds in 3 tablespoon of water and wait ten minutes then use it as a substitute for egg in the recipe)
keep them dairy-free - you can use oat milk as suggested, or almond milk
add more sugar - add another teaspoon of honey or regular sugar to the batter if you want them sweeter
add mix ins - you can add chopped strawberries, blueberries or some nuts in the mix
