"This really a scrumptious cake, though it is true, as some reviewers have noted, that the frosting just barely covers all three layers. You could double the recipe, as some people have done, or you could make a batch and a half. Your call. To make a batch and a half, the measurements would then be: 3/4 cup butter; 1-1/2 cups dark brown sugar; 1/4 + 2 tablespoons milk; and 3 cups of confectioner's sugar. Hopefully, this will give you enough frosting without having too much left over in your bowl, which, if you're anything like me, you will then be forced to eat at least *some* of, so as not to have to wash it all down the sink. ; )..."
