Preheat your oven to 350°F (177°C).
In a large mixing bowl, combine the mashed bananas and unsweetened applesauce. Stir until well mixed.
Mix in the vanilla extract and ground cinnamon until evenly distributed.
Add the oats to the banana mixture and stir until fully combined.
Pour in the almond milk to moisten the oats. Incorporate raisins or nuts along with dark chocolate chunks.
Line a baking sheet with parchment paper or lightly grease it.
Spoon out portions of the mixture onto your prepared baking sheet and flatten slightly.
Place the baking sheet in your preheated oven and bake for 15-20 minutes, or until firm and lightly golden.
Once done, remove the cookies from the oven and let them cool on the baking sheet for a few minutes before transferring them to a wire rack.
Once cooled, these Healthy Cookies Without Sugar are ready to be served.
