Prepare flax "egg" by whisking flax meal (or ground flaxseeds) with water. Let it sit to thicken.
In a preheated sauce pan, heat coconut oil to a low until it is fully melted. Turn off heat and allow it to cool for 2 minutes.
Mix in sugars, black coffee, and vanilla. Whisk until fully combined. Stir in flax egg until smooth.
In a large mixing bowl - add the flours, cocoa powder, salt, baking soda & powder. Stir until well combined.
Pour in liquid ingredients to the dry little by little. Stir until it forms into a very soft dough.
Fold roughly chopped dark chocolate and chocolate chips to the dough. Let it chill for 1 hour in the refrigerator.
Preheat oven to 375°F.
Line parchment paper on a baking sheet. Scoop each cookie dough (using a cookie scooper) and place on sheet. Space apart as they will spread. If you don't have a cookie scoop, use a tablespoon and form a cookie dough ball about 1-1.5" in diameter.
Bake for 12-13 minutes. You will know if it's ready if edges are a darker brown. They may seem underdone but it will firm up once it's cooled down.
Place on a cooling rack for about 15 minutes before indulging. Enjoy!
