In a large bowl, mash bananas with a fork until soft and broken down.
Add the rest of the ingredients and mix well. Place in refrigerator 20-30 minutes to firm up.
Scoop 1-2 tablespoons mixture and form into a ball.
Enjoy immediately or refrigerate leftovers.
Notes
Refrigerating will help firm dough up and make forming into balls much easier. It will also give the whole grain oats time to absorb moisture from the banana and stick together.
