Preheat the oven to 325°F and grease an 8x8 oven safe pan with coconut oil.
In a mixing bowl, combine the dry ingredients. In a separate mixing bowl, stir together eggs and mashed avocado until combined.
In a small sauce pan add the butter and chocolate chips and slowly melt.
Gradually mix the dry and wet ingredients, followed by melted butter and dark chocolate.
Use a spatula to evenly spread the batter into the prepared pan. Bake for 30-35 minutes. Cool the brownies to room temperature before cutting.
