Peel white chocolate away from Magnum® stick but do not chuck the white chocolate away. Place ice-cream in blender, if blender not applicable use a container that has a secure lid. Add in milk, and if you're a big fan of thick milkshakes, add some cream or even another dollop of Magnum® ice-cream.

If using a blender, now place the white chocolate that you peeled from the Magnum® ice-cream in too. Blend and serve. If using a container, place the lid onto the ice-cream-milk mixture and shake vigorously. Once shaked, pour into drinking cup. Crumble white chocolate and sprinkle on top. Add whipped cream on top of shake.
