Break your frozen bananas into a few pieces and put into the food processor.  Process until the bananas are completely broken down and you have a smooth texture like that of soft serve ice cream.  This will take 2-5 minutes.  Add the maple syrup and cinnamon and stir or process again until they are incorporated.  Don’t over-process or the soft serve will get too soft. Top each serving with 1-2 cookie dough balls and serve immediately.
