Add milk, cocoa powder, and sugar to a medium saucepan and mix well.
Cook over medium heat until the mixture comes to a boil, stirring frequently to avoid scorching at the bottom of the pan.
Add Oreos cookies and stir until they are dissolved and the hot chocolate is creamy.
Pour into 2 serving mugs and top with whipped cream. Sprinkle some crushed ores on top and serve.
