Place all ingredients in a blender and pulse until smooth, scraping down sides with a rubber spatula if necessary.
Heat a non-stick skillet over medium heat and spray with cooking spray. Pour batter on heated skillet, about ¼ cup at a time, and cook until bubbles begin to form.
Flip pancakes and brown on second side. Continue until all batter is gone.
Serve with banana slices and maple syrup if you wish although they are delicious plain.
