Mash the bananas in a medium bowl. Add the egg and milk and mix everything together well.
In a separate bowl, mix all the dry ingredients together.
Add the dry ingredients to the wet ingredients and fold the mixture until just combined.
Cook pancakes in a greased pan on low-medium heat, ~2-3 minutes per side or until cooked through.
Notes
You can substitute the 100% white flour with 50% white flour and 50% whole wheat flour, or 75% white flour and 25% almond flour! I suspect this recipe will work well with other flour types and combinations, but these are the ones I've tried so far.
