Preheat the oven to 350°F.
In a small bowl combine the flax and water and mix well. Let it sit for 5 minutes until it gets thick to create two flax eggs.
Whisk together the oat flour, almond flour, salt and baking powder in a bowl. Add in the coconut sugar, almond butter and vanilla. Add in the flax egg and mix well until a dough forms.
Roughly chop the chocolate chips and add them to the dough.
Bake the cookie on a parchment-lined baking sheet and bake at 350°F for 15-18 minutes or until the top cracks. This cookie won't spread, it will just puff up, so be sure to shape it in the shape you want it when it comes out!
Serve warm :) This will serve 1-2 people.
