This royal icing recipe is the key to building sturdy, beautiful gingerbread houses. It dries hard and strong, holds even the heaviest candy decorations, and comes together in just 10 minutes with simple ingredients.
Start with a stiff consistency for gluing gingerbread walls. Let the icing rest for 5 minutes after whipping to allow air bubbles to rise. Keep a damp paper towel over the bowl of icing at all times to prevent crusting. Practice on parchment paper before piping on the gingerbread house. Work on one side of the house at a time and let the icing dry completely before moving to the next side.
