In a food processor or blender, process/blend the almond milk and spinach together until smooth and no chunks of spinach is left. Then add the coconut oil, bananas and vanilla and process/blend until smooth. Pour mixture into the bowl of dry ingredients.
Pour or scoop batter evenly between muffin tins. They should be 3/4 of the way full. Top each muffin with an optional banana slice.
Bake until firm and slightly golden or until a toothpick inserted in the middle comes out clean, about 25-30 minutes. Let cool and enjoy!
