Make sugar syrup, by mixing (and boiling if you’re not lazy like me) water and sugar in a food processor, until sugar completely dissolve. If you have a powerful blender, add them to the blender instead processing separately.

Drizzle sweetened condensed milk generously on the inside of serving glasses (this recipe makes 2 giant glasses/mugs)

Pour sugar syrup into a blender, add in the rest of the ingredients. Blend until super smooth and creamy.

Pour smoothie into prepared glasses/mugs, serve immediately. If wanted, drizzle more sweetened condensed milk on the smoothie, just before serving.
