Preheat the oven to 350°F (180°C) and line a baking sheet with parchment paper or a silicone baking mat.
Mix the dry ingredients: In a large bowl, combine the oats, flour, baking soda, and salt. Stir well until all dry ingredients are evenly mixed.
Add the wet ingredients: In a separate bowl, whisk together the melted coconut oil, coconut sugar, maple syrup, and vanilla extract until smooth.
Combine the mixtures: Pour the wet ingredients into the dry mixture and stir until a dough forms. Fold in the chocolate chips and nuts (if using) until well distributed.
Shape the cookies: Use a spoon or your hands to scoop small portions of dough and form into balls. Place them on the prepared baking sheet, leaving space between each cookie as they will spread slightly.
Bake: Bake the cookies for 10-12 minutes, or until the edges are slightly golden but the center remains soft. The cookies will firm up as they cool.
Cool and enjoy: Let the cookies cool on the baking sheet for a few minutes before transferring them to a wire rack to cool completely.
