In a medium bowl, whisk together the 0 calorie brown sugar, applesauce, vanilla and oil until well combined. Fold in the flour and baking soda, combine to form a dough.
Make the cinnamon sugar by mixing together the sweetener and cinnamon until well combined. Divide the dough into 3 equal balls and roll each ball in the cinnamon sugar until well coated.
Place the cookies onto a prepared baking tray. Flatten them slightly before placing in the oven.
Bake for 8 minutes, the cookies may look underdone but they will bake as they cool so make sure you don't over-bake them.
Let the cookies cool on the tray for 5 minutes before transferring to a cooling rack to cool completely. Enjoy!
