Set to 350°F (175°C). Line your baking sheet with parchment paper.

In a medium bowl, combine oats, flour, baking soda, baking powder, cinnamon, and salt. Stir well.

In a large bowl, whisk together melted coconut oil, brown sugar, applesauce, and vanilla extract until smooth and creamy.

Gradually add the dry mixture to the wet ingredients. Stir until a soft dough forms.

Fold in chocolate chips, raisins, or nuts if using.

Drop tablespoon-sized balls of dough onto the prepared baking sheet, spacing them about 2 inches apart. Flatten slightly with your fingers or the back of a spoon.

Bake for 10–12 minutes, or until the edges are golden brown.

Let cookies rest on the sheet for 5 minutes, then transfer to a cooling rack.
