It turns out that Bailey's really, really works. I wound up using Ghirardelli milk baking chocolate as well as 60% dark, because I thought the dark might not jive so well with the Bailey's flavor-- it turns out that a bag of white chips and a bag of milk chips thrown in as chips, a bar of dark melted into the batter, and a milk ganache is Precisely Correct.

Thank you so much for the recipe!
