Hate to break into the Illinois fest going on, but this Okie would never vote for freezing baked cookies, either decorated or not. I make the dough up ahead of time and freeze it, but that's as far as I go.
I'm assuming you're talking sugar cookies mostly. I'm not sure it would really change the taste if frozen properly, but I like nice crisp sugar cookies and I just think you lose that fresh baked crispy taste with freezing.
What about making the dough, rolling, cutting and freezing? That would save some time and not affect the quality at all.
Oh and Boomer Sooner!
