Preheat oven to 375°F and line a muffin tin with liners.
In a large mixing bowl, combine mashed banana, egg, melted coconut oil, and coconut sugar. Mix until well combined.
Sift in all-purpose flour, cinnamon, salt, and baking soda. Gently fold until just combined; avoid over-mixing.
Fold in dairy-free chocolate chips.
Use a double cookie scoop to portion batter into prepared muffin tin.
Bake for 23-25 minutes, or until golden brown and a toothpick inserted in the center comes out clean.
Allow to cool slightly before serving and enjoy!
