How do you maintain the freshness of your cookies while waiting for the icing to harden so you can package them?
I have just left them on the cooling grids lined with parchment. The humidity keeps them soft but the icing dries, almost oxymoron like I know, but it works for me. I can usually package the cookies within 6 hours shorter if I use a heat lamp. HTH
I usually package them within one day of icing them, and I have never had a problem with the cookies not staying fresh. I usually let them dry on a cookie sheet or a cooling grid and they are uncovered....You should be fine.
I just leave them on the cooling racks to dry. I take them off the parchment they baked on when cool, put them onto sheet pans with fresh parchment, ice and decorate, then leave out to dry. They can't be covered or in a tupperware because the icing won't dry. My cookies stay moist, especially in warmer weather with humidity, and absorb moisture/butter from the icing (depending on what icing is used). I then package them the next day -making sure the icing is set. I usually make scrap cookies with the remaining dough -taste testers and for trial decorating and testing for dryness.
It's so weird. I have never had my cookies soften no matter how long they sat out to dry. Yet today, my iced cookies were so soft. It is humid today but it's been humid before when i had cookies out drying. Go figure. I'm not thrilled about this softness cuz now i'm nervous they will break easily while packaging and in transit..........
