Cut the avocado vertically into half. Twist the fruit so that the pulp gets loosened from the pit. Remove the pit and with a spoon, scoop out the flesh.
Put the avocado flesh in a blender. Add the sweetener. Add half a cup of milk and blend well. Now, add the remaining milk and blend again. This ensures a rich, creamy texture. You can add a couple of ice cubes and give it a whiz.
Serve chilled and enjoy!
You can substitute cow's milk with any kind of nut milk such as coconut milk, almond milk, or cashew milk. Coconut milk will give it a creamy texture. However, if you use almond or cashew milk, the drink will be thinner in its consistency.
