Dark chocolate/walnut oatmeal cookies

A humongous thank-you to my sister in Ohio for this base recipe. I altered it just a tad and added some extra ingredients and voila! The best (and easiest) oatmeal cookie of all time.

Original Ingredients:
Slow-cook oats
Banana
Brown sugar
Melted Earth Balance
Vanilla
Baking Soda
Whole grain flour

I added few treats:
Bran
Flax seed (ground)
Dark chocolate chips
Chopped walnuts
