Preheat your oven to 350°F (175°C) and line a baking sheet with parchment paper.

In a large bowl, whisk together the flour, baking soda, baking powder, salt, cinnamon, and nutmeg.

In another bowl, mix the melted coconut oil, brown sugar, maple syrup, and vanilla extract until well combined.

Gradually add the wet ingredients to the dry ingredients, stirring until just combined.

Fold in the diced apples, rolled oats, walnuts, and raisins if using.

Using a tablespoon, scoop the dough onto the prepared baking sheet, spacing them about 2 inches apart.

Bake for 12-15 minutes, or until the edges are lightly golden and the cookies are set.

Allow the cookies to cool on the baking sheet for 5 minutes before transferring them to a wire rack to cool completely.
