Melt gula melaka and water in a saucepot over medium heat, until all the gula melaka has melted.

In a blender, add avocados, milk, ice cubes and gula melaka syrup. Blend until smooth and all the ice cubes have been crushed. If you want to adjust the sweetness level of each cup, don't blend the gula melaka syrup with the rest of the ingredients. Instead, add gula melaka to each cup individually after blending the avocados, milk and ice cubes.
