Preheat oven to 350 degrees F (180 degrees C).
In a bowl, add Ground Oats (1 cup), Oats (1 cup), Chia Seeds (2 tablespoon), Baking Soda (1 teaspoon), and Salt (1/2 teaspoon). Mix well and set aside.
In a separate bowl, add Banana (1/3 cup), Coconut Oil (1/3 cup), Unsweetened Apple Sauce (1/2 cup), Pure Maple Syrup (1/4 cup), and Vanilla Extract (1 teaspoon). Mix well.
Add favorite mix-ins, such as Vegan Chocolate Chips (2/3 cup), Slivered Almonds (1/3 cup), Chopped Pecans (1/3 cup), Raisins (1/3 cup), or Unsweetened Shredded Coconut (1/4 cup) to dry ingredients and mix well. Pour dry ingredients into wet ingredients and stir well.
Form 2 to 3-inch cookies on a silicone baking mat or greased cookie sheet. Bake for 12-17 minutes, until done. (For bars, use a 9x9-inch baking dish or round baking pan and check after 20 minutes, baking until center is done.)
Once cooled, seal in an airtight container for several days or wrap individually in foil and freeze. Heat for 20-30 seconds on high in the microwave from frozen. Enjoy!
