Preheat your oven to 350 ℉ and line a 12-hole muffin tin with liners. Set aside
In your blender, combine eggs, banana / applesauce, carrots, spinach/kale, maple syrup/ honey, oil, vinegar, and vanilla.
Blend until mixture is smooth.
Add flour, baking powder, baking soda, salt, cocoa powder and cinnamon. Process until just mixed. If you do not have a high speed blender, combine everything in a bowl and mix by hand.
Finally, fold in chocolate chips (if using).
Portion batter into prepared muffin tin and top with extra chocolate chips if desired.
Bake for 20-22 minutes or until a toothpick inserted into the middle comes out clean.
Let cool in pan for 5 minutes before transferring to a cooling rack. Enjoy and let cool completely before storing leftovers in an air-tight container in fridge or freezer.
