Preheat oven to 365 degrees F. In a bowl combine all the wet ingredients and mix until well combined.
Whisk oat flour, baking powder, salt, and almond meal. Add to the wet ingredients. Add in the oats and mix until well combined. Fold in the chocolate chips and walnuts to distribute evenly. The dough will be somewhat sticky. (Add more flour if too wet, or a dash of non dairy milk if too dry).
Cover and chill in the refrigerator for 15 minutes. Dampen your hands with water to prevent dough from sticking to your palms. Take 2 to 3 Tbsp of the dough and make large cookies. Flatten lightly on the sheet. Press the leftover chocolate chunks (there will be few towards the end), into the shaped cookies. (I had to get my hands wet a few times because the dough kept sticking to me and it was difficult to shape them.)
Place baking sheet on the center rack. Bake for 10 to 12 minutes. Careful not to overcook because they harden as they cool. You want the middle to still be soft.
Cool for 10 minutes before serving.
Enjoy!
