Preheat your oven to 350°F (175°C) and line a baking sheet with parchment paper.
In a large mixing bowl, combine the almond flour, rolled oats, baking soda, and salt. Stir until well mixed.
In another bowl, whisk together the melted coconut oil, maple syrup, and vanilla extract until smooth.
Pour the wet mixture into the dry ingredients and mix until a dough forms.
Fold in the dark chocolate chips and crushed walnuts, if using, until evenly distributed.
Scoop tablespoon-sized balls of dough onto the prepared baking sheet, spacing them about 2 inches apart.
Flatten each ball slightly with the back of a spoon or your palm.
Bake for 10-12 minutes, or until the edges are golden and the centers are slightly soft.
Remove from the oven and let the cookies cool on the baking sheet for 5 minutes before transferring them to a wire rack to cool completely.
Notes
Serve the cookies on a wooden platter with a sprinkle of sea salt on top and a few extra chocolate chips for a delightful finish. Enjoy with a glass of almond milk for the ultimate treat!
