Preheat the oven to 350*F (177*C). Line a baking sheet with parchment paper and lightly brush with coconut oil.
In a large bowl, combine the oat flour, whole oats, baking soda, cinnamon and salt. Add the remaining ingredients, except the chocolate, and mix well. Once the coconut oil is well combined, add the chocolate.
Using clean hands, form 1-inch (25-mm) balls and place on baking sheet. Once you have finished using all the dough, use a fork and lightly press down on each cookie.
Bake for 10 minutes. Remove from the oven and let cool for at least 15 minutes. Do not over-bake these cookies, especially if you prefer a chewier texture.
How do I make oat flour?One of the easiest healthy substitutions you can make in your baked recipes is to replace plain white flour with oat flour. Oat flour is essentially finely processed ground oats and here is how to make it: To replace 1 cup (125 g) of white flour, you will need 1 heaping cup (80 g) whole rolled oats, certified gluten-free if necessary. Pulse oats in food processor/ blender/coffee bean grinder until oats resemble fine crumbs/flour.
