Add all the ingredients to a blender and blend on high speed until smooth, about 1 minute.
Taste and add a little bit of maple syrup or more banana if it's not sweet enough for you. Adjust consistency if needed, adding more banana to make it thicker, or milk/water to thin.
Divide into regular or shot glasses, and serve immediately. It's best enjoyed immediately but can be kept covered in the refrigerator for a few hours.
Notes
Nutrition information is calculated with full-fat coconut milk and coconut oil.
I like to use half coconut milk and half almond milk.
