Preheat oven to 350°F. Line muffin pan with paper liners. Set aside.
In a medium bowl, whisk together flour, baking powder, baking soda, salt, and cocoa powder. Set aside.
In a large, bowl, smash your ripe avocado with a fork or pastry blender. With a spatula, mix in applesauce, vanilla extract and sugar with your mashed avocado. Pour bowl of dry ingredients into your bowl of wet ingredients. Combine flour and avocado mixture until there are only a few streaks of flour left. Fold in the chocolate chips.
Use a cookie scoop to scoop and divide batter evenly into the muffin cups. Bake at 350°F for 40 minutes. Once muffins are cool enough to remove from the pan (about 5 minutes), place them on a wire rack so that the moisture can evaporate from the bottoms and they can continue to cool.
