Preheat oven to 350F. Have an 8" x 8" pan lightly greased, dusted with cocoa powder, and lined with parchment paper at the bottom. Set aside
In a medium to large bowl, whisk well: mashed avocado, honey and/or maple syrup, and coconut oil. Set aside.
Place chocolate chips in a bowl. Heat coconut milk until hot (just before it boils) and pour over chocolate chips. Stir until chocolate completely melts. Then pour melted chocolate into the avocado mix, and whisk very well until you get it as smooth and silky as possible.
In another large bowl, sift together flour, cocoa, baking soda, and salt.
Add avocado mix to dry mix, and using a spatula or a wooden spoon, stir until combined.
Pour batter into prepared baking pan, and place in the oven to bake for 30-35 minutes. See NOTES for times.
Remove and allow to slightly cool before diving in.
