If you plan to freeze these cookie bars, for all crumble type cookies, I always thaw them on a wire cake rack and never in a closed container. There's a lot of humidity in some freezers that gets trapped inside and can start to make baked goods soggy as they thaw. My method always avoids that problem for me.
