Does frosting go hard?

Yes, frosting can harden, especially buttercream and sugar cookie icings, but it depends on the type: Royal Icing (egg whites/meringue powder) hardens completely, while Buttercream (butter/sugar) forms a slight crust and firms up, and Store-bought frosting usually stays soft but can get a dry crust. Hardening is caused by sugar drying and setting when exposed to air or refrigerated, but you can help it along with chilling or specific ingredients like egg whites for a firm finish.

How long does it take for frosting to harden?

Icing setting time varies, but generally, a thin crust forms in 15-30 minutes, while full hardening can take 6-24 hours, depending heavily on the icing type (royal vs. glaze), thickness, and humidity. Royal icing needs 6-8 hours for a firm crust, but 12-24 hours to fully harden for stacking. Thicker icings or high humidity slow drying.
