Simple. Healthy. Vegan. The indulgent part here is the mini chocolate chips, otherwise only whole plant foods! So of course you could make the chips optional or suns for raisins or something, but what can I say? Chocolate.
You need:

2 very ripe Bananas

1.5 cups rolled Oats

1/3 cup mini chocolate chips (I like Enjoy Life brand)

Yields about 14

Combine all ingredients in a bowl, mashing banana and oats before adding the chocolate chips, and drop by sooonfuls on lined cookie sheet. 

Bake at 350 x 15min.
That is it! Store in sealed container in the fridge, but the texture is best when fresh.

Enjoy!!
