I just put together a recipe for Mudder's Milk this evening, before I looked and found this thread!
I've got a 14-grain-pound oatmeal stout, mixed with 4.5 pounds of dark brown sugar and honey in a small beer, pitched under some high-gravity ale yeast. BeerSmith thinks this will yield 15.1% ABV if I do it right.
Obviously I haven't tried making it yet, it's possible my brew setup isn't capable of handling this much grain. But if I do, and it works, I'll happily post the recipe for other lunatics to try it themselves.
