Place the full-cream milk, chocolate ice cream, vanilla ice cream, hot chocolate powder, vanilla powder, and ice in a blender.
Turn the blender on and blend the ingredients on high until it is a completely smooth texture. It should be thick but not too thick. If it is not the right consistency, add a splash of milk and blend. Adjust accordingly until it is at the perfect consistency.
Pour the blended mixture into the serving cups or mugs.
Top with whipped cream if you please.
You can also top with chocolate sprinkles.
The iced chocolate is best served chilled. Enjoy!
