Cut your banana in half.  Mash one half until smooth-ish consistency in a small bowl, then add egg whites.  Whisk in cinnamon, stevia and vanilla extract if desired (makes it a bit sweeter and more flavorful.)

Grease pan with cooking spray or butter.  Pour mix into the pan and then turn on the heat to medium (careful not to turn it up too high or pancake with char before it's set).  Let pancake set while the pan and pancake heat up.  I usually put away dishes or do something else so I don't have the urge to flip it too early!  After about 5 minutes (when the pancake is almost set), spray with cooking oil spray and flip.  Flipping takes a bit of practice but the great thing is if you miss your first couple tries this is just as delicious as a scramble.  You can then flip back and forth until fully cooked, top with the rest of the banana and desired other toppings! I LOVE it as a mode for different types of nut butter.
