This easy Gingerbread Icing recipe uses just 3 simple ingredients–egg whites, powdered sugar, and cream of tartar– to create the perfect royal icing ‘glue' for assembling and decorating gingerbread houses.

My Go-To Gingerbread Royal Icing
If you need icing that's going to glue together a gingerbread house fast, this is the recipe for you! We use it for our homemade gingerbread house and it's quick and easy to make, easy to pipe and decorate and strong enough to hold the pieces together if you want to use it for that instead of our sugar method.
Be sure to keep a damp cloth over the bowl while decorating to prevent it from drying out! Also don't use a plastic bowl to make royal icing! Use a glass or metal mixing bowl!

My Go-To Gingerbread Royal Icing
Can I make this icing a day in advance or will it deflate because of the whipping of the egg whites or will it harden too much that we won’t be able to pipe it on?
Royal icing doesn’t store well made in advance. The egg whites will deflate and it will harden too much to pipe easily. It’s best to make it fresh when you need it since it only takes about 7 minutes. If you absolutely must make it ahead, you can store it in an airtight container in the fridge for a few hours and re-whip it briefly before using, but it won’t be as good as fresh. Keep a damp cloth over the bowl while working to prevent it from drying out.
