Holy crap, these are terrible. The ice cream texture is icy, the ice cream flavor is artificial, the cookies taste like some kind of floury mess with fake chocolate chips in them.
The chocolate chips are NOT fake, though. They just taste terrible and waxy. The cookie is the way it is, I assume in an attempt to prevent them from becoming too hard when frozen. So, instead of just using real cookies that taste good and accepting that people might have to chew a bit, we have this mess. It tastes and feels like a cookie in which the baker accidentally added too much flour and then also baked the cookie for about half the necessary time.
Everything about this sandwich is bad. It's only redeeming quality is that it is not poisonous.
