Pre-heat oven to 350 degrees and line a baking sheet with parchment paper or Silpat.
In a large bowl, combine mashed banana with oats, applesauce, maple syrup, flaxseed meal, and dried cranberries.
Drop 1 ½ Tbsp of dough on prepared baking sheet. If you want more "cookie-like" cookies, flatten dough a bit with the palm of your hand.
Bake for 20 minutes. Let cookies cool on baking sheet for a few minutes before moving to racks to cool completely.
