I prefer chocolate malts to chocolate milkshakes -- the maltier, the better. I've always liked malted milk, too, and malted milk balls? Yum!
I'm not sure why I have such a thing for malted milk and malts in general, but I don't ever remember not liking malted milk. Any time I've been somewhere that sold hand-dipped milkshakes, I've always ordered a chocolate malt. And don't just wave the chocolate syrup over the cup. Have the decency to actually put some chocolate syrup in there, at least enough to taste! It irks me to get a chocolate malt and not be able to taste either chocolate or malt!
