In a saucepan, warm up the whole milk and cream together. Once tiny bubbles appear on the side of the pan, the milk is hot enough to remove.
Add the white chocolate to a small bowl. Pour in the hot milk, whisking slowly to allow chocolate to dissolve. Keep whisking until all of the chocolate has been combined with hot liquid thoroughly. Alternatively, you can add the white chocolate to a blender and pour in the warm milk. Cover blender and pulse until chocolate has dissolved into the milk. The blender method would also create froth on the hot white chocolate. Serve.
You can put toppings on the hot white chocolate including marshmallow, cinnamon, nutmeg or even biscotti.
