Preheat your oven to 350°F and line a 12-cup muffin tin with liners.
In a high-speed blender, combine eggs, banana, applesauce, carrots, spinach/kale, avocado oil, honey, vanilla extract, and apple cider vinegar. Blend until smooth.
In a large bowl, whisk together almond flour, baking soda, baking powder, chocolate protein powder, and cinnamon sugar.
Pour the blended wet mixture into the dry ingredients and mix until just combined.
Fold in chocolate chips if using.
Divide the batter evenly into the muffin tin. Sprinkle extra chocolate chips on top if desired.
Bake for 25-28 minutes or until a toothpick inserted into the center comes out clean.
Let muffins cool in the pan for 5 minutes, then transfer to a cooling rack. Allow to cool completely before adding icing or storing.
