4-5 ounces 100% dark chocolate bar (Found in the baking section in the grocery store. I suggest Baker’s chocolate or Ghiradelli unsweetened)
Preheat oven to 350*. Mash the bananas, and mix in the other wet ingredients. Then add the dry ingredients and mix until well-incorporated. Next, chop the chocolate bar into small chunks and mix into batter. Drop Tablespoons-full of dough onto a cookie-sheet about 1/2 inch apart. Bake for 15 minutes, or until the bottoms of the cookies are golden brown.
