In a medium bowl, combine the flours, cocoa, baking soda, and salt.
In a standing mixer bowl, blend the brown sugar and Truvia. Slowly beat in the coconut oil. Add in the mashed or blended avocado, egg whites, and vanilla. Blend on low speed until smooth.
Add the flour mixture and chocolate chips and blend on low speed until the dough is just combined. Dough will be crumbly. Refrigerate for about 1 hour.
Preheat oven to 300º F. Spray a cookie sheet with cooking spray. Roll the dough into small balls and place on cookie sheet. Flatten slightly and bake for 17-19 minutes (do not over bake!) Transfer the cookies to wire racks to cool. Enjoy!
