These were yummy!
I found the recipe from here:
http://freshfitnhealthy.com/2014/01/pumpkin-banana-breadmuffins-with-protein-chocolate-chips/

I used semi sweet chocolate chips, and more pumpkin that I had left over from a pie I made that was in the freezer. Also rather than making a loaf or a full batch of muffins I used these little silicone baking cups to get the shape and have less dishes! My son put his in hearts and gave me one, swoon! He also ate two muffins for dinner, none the wiser that it was a healthy treat!
