I've seen these kind of cozy-ass photos of hot chocolate on tumblr, even reblogged them, I love 'em, BUT I've never drank it that way.

Well, I did try to add marshmallows to my drink once but as your post suggests, I should have started adding them while heating the milk. My cup was more like cocoa gone from hot to warm and huge marshmallow just floating there in the way of me drinking.

Will try out your way some day for sure.
