My mother freezes cookies and stuff for months. And they are just fine, never had a problem with them.
My mom makes what are called poorboys, its a cake type bar with a creamcheese icing, we love it and it's a tradition. Of course rum balls, peanutbutter cookies, sugar cookies, all the usual stuff. And I carry on those for my family.
I may grow older, but I refuse to grow up.
