There is a reason that whoopie pies have sweet sugary icing and not cream cheese icing. I've bought these twice here (two different flavors--for $2.50 each), each time disappointed to find cream cheese inside. This is wrong. I can't stand it--I have to push it off on my husband because there is no point in eating it at all as far as I'm concerned. Don't tempt me with my favorite dessert and then try to improve on it, ruining it entirely.
(The reason is, I think, that the cookies aren't as sweet as normal cookies, so the blast of sweetness comes in the icing. And cream cheese just doesn't cut it. Bleh.)
