Preheat your oven to 350°F (175°C) and line a baking sheet with parchment paper.
In a large mixing bowl, combine the rolled oats, whole wheat flour, baking soda, cinnamon, and salt. Mix well to ensure the dry ingredients are evenly distributed.
In a separate bowl, whisk together the melted coconut oil, maple syrup (or honey), applesauce, and vanilla extract until fully combined.
Pour the wet ingredients into the dry ingredients and mix until just combined. Be careful not to over-mix.
Gently fold in the raisins, walnuts, and dark chocolate chips, if using.
Scoop out tablespoon-sized portions of the dough and place them onto the prepared baking sheet, spacing them about 2 inches apart. Gently flatten each cookie slightly with the back of the spoon.
Bake in the preheated oven for 12-15 minutes, or until the edges are golden brown.
Once baked, remove the cookies from the oven and let them cool on the baking sheet for about 5 minutes before transferring them to a wire rack to cool completely.
Notes
Serve these cookies on a colorful plate alongside a glass of cold almond milk for a delightful breakfast spread!
