Preheat oven to 350 degrees F. Grease a 12 muffin tin pan.
In a large bowl, mix the olive oil, coconut sugar, eggs, vanilla, mashed bananas, and almond milk together. Whisk until well mixed.
In another bowl, combine the almond flour, tapioca flour, coconut flour, baking soda, salt, and cocoa powder together. Mix with a fork until blended.
Pour the bowl of dry ingredients into the bowl of wet ingredients and mix until just combined. Fold in the dairy-free chocolate chips.
Bake for 25-30 minutes, or until a toothpick comes out clean.
