Preheat oven to 350 degrees F. Line a 8×8 square baking pan with parchment paper.
In the bowl of your stand up mixer (I used my KitchenAid), make your flax eggs by combining the ground flaxseed and water. Stir and set aside for 5 minutes to thicken.
Once flax egg has thickened, add the coconut oil, coconut sugar, and vanilla extract to the mixing bowl. Mix with paddle attachment until well combined.
Then add the almond flour, baking powder, and salt. Mix until combined. Add the macadamia nuts and chocolate chips. Mix until combined.
Pour batter into the prepared pan and smooth it out evenly. Sprinkle extra macadamia nuts and chocolate chips on top if you would like. Bake for 25-28 minutes or until golden brown and the top is set. Let it cool in the pan on a wire rack completely before slicing. They are supposed to be fudgy. Enjoy! Store in the fridge. They will firm up in the fridge so when you want to eat them, heat it up in the microwave for just a few seconds to soften them again.
