Place a large, non-stick skillet on the stove over medium low heat.
Add the ingredients into a high speed blender in order as listed (bananas first, then eggs, water, etc.). Don't add the vinegar yet.
Blend everything until smooth for about 10-20 seconds.
At the end of blending, add in the vinegar and briefly blend the mix again (about five seconds), just to incorporate it.
Add a pat of butter to your pan and let it melt.
When you see tiny bubbles begin to form in the butter, begin adding the batter into the pan.
Cook the 'cakes until you see bubbles form on the surface.
Carefully flip the pancakes over. Go slow to determine if they are going to hold together.
Cook the opposite side for 15-30 seconds or until cooked through.
Place the pancakes onto a plate and repeat the process with the remaining batter.
Top as desired and enjoy!
