Chocolate milk stout

[KingBeer]

I am planning on brewing a Chocolate milk stout in the next few weeks. I want to add something extra to it but can't decide on what would be good. I was thinking about adding a coconut flavor or a vanilla flavor. Any other ideas on what to add to make it more than just your everyday chocolate milk stout?

Vanilla can often come through as chocolate notes, so I think that would help kick it up a notch.

I'm planning to brew a chocolate raspberry porter in the next couple weeks, so that could be something to consider.
