Preheat oven to 350°F. Line a baking sheet with a silicone baking mat or parchment paper.

In a large bowl, add applesauce and oats. Mix with a spoon until evenly combined and all oats are moistened.

Stir in mix-ins.

Use a 1.5 tbsp cookie scoop and scoop dough balls, placing them onto the prepared baking sheet, spaced 2 inches apart.

Press down on dough balls to form thick round disks (about 3/8 inch thick).

Bake cookies for about 13-15 minutes or until they are set.

Let cookies cool before removing and eating. Store cookies in an airtight container at room temperature for 1-2 days or in the fridge or freezer for longer.
