May I introduce you to the MVP of gingerbread houses? The glue that holds the whole house together is- drumroll please… royal icing. If you haven’t discovered the magic of Royal Icing for Gingerbread Houses you are in for a real treat!

Royal icing is made with powdered sugar, egg whites and water. However, if you are going to consume your gingerbread house instead of using it for a decoration, you can use powdered sugar, meringue powder which is pasteurized powdered egg whites, and water. It’s a personal preference, so use what feels better to you! When the icing is done can view my master gingerbread house recipe with 2 free templates here. You can also make a haunted gingerbread house for Halloween!

Royal icing is really easy to work with but more importantly is essential to the successful construction of a gingerbread house. The icing will become rock hard when it air dries. It will hold the walls and roof on as well being used to stick candy on the house too. The best way to use the icing is to transfer it to a piping bag. You will be able to be more detailed using a bag and can get into the cracks and crevices better.

How to Make Royal Icing

Royal Icing with Meringue Powder:

Step 1. Mix powdered sugar and meringue powder in a bowl with 10 tablespoons of water.

Step 2. If making with egg whites, mix egg whites and powdered sugar in a bowl with 5 tablespoons of water.

Step 3. Beat with a mixer until well incorporated and shiny, adjusting water for desired consistency.

Step 4. Keep the icing covered with a wet towel or plastic wrap to prevent hardening when not in use.

Recipe FAQs

Expert Tips

• You can have no leftover grease in your bowls, on your spoons, or in your icing bags. I keep separate icing bags just for royal icing because buttercream is so hard to clean off the plastic.
• Make sure there is no trace of egg yolk if you are using egg whites in your icing. That little bit of fat, either from the yolk or leftover on your bowls will ruin the batch of icing and keep it from setting up properly.
• You can use raw egg whites or pasteurized eggs whites depending on what you are comfortable with.
• The icing should be thick enough to hold its shape but still manageable to stir with a spoon. If the icing is too thick, add water gradually; if too thin, add more powdered sugar.
• When you are ready to put your house together, put about 2 cups of your royal icing in a piping bag or a good quality freezer zipper-topped plastic bag. Use a frosting tip that is about ½ inch wide circle or cut about ½ inch off the tip of one corner of your baggie. If the hole is too small it’s really hard to get the icing to come out. I do this bigger tip for assembling the house and move to a smaller tip when I’m ready to add decorations and candy.
• When not in use, cover the icing with a wet dish towel or press plastic wrap directly onto its surface to prevent it from hardening.

Instructions 

To make royal icing with meringue powder:

• Add your powdered sugar and meringue powder to a large mixing bowl. Add 10 tablespoons of water to the bowl.
• Use a stand mixer or a hand mixer to beat until well incorporated. If the icing is very crumbly, add more water, 1 tablespoon at a time until it creates a thick but smooth icing. I normally end up adding 4 more tablespoons of water and sometimes the full 5, it’ll depend on how you measured your powdered sugar though.
• Beat until the icing is shiny, about 6-8 minutes with a stand mixer and 8-10 minutes with with a hand mixture. 
• The icing should be thick but not so thick you can’t stir it with a spoon. Adjust the constancy as needed. 
• When you aren’t working with your royal icing place a clean wet dish towel over the top of the icing so that it doesn’t start to harden. You can also press a piece of plastic wrap against the top of the icing. 

To make royal icing with egg whites: 

• Add your egg whites and powdered sugar to a large mixing bowl. Add 5 tablespoons of water to the bowl.
• Use a stand mixer or a hand mixer to beat until well incorporated. If the icing is very crumbly, add more water, 1 tablespoon at a time until it creates a thick but smooth icing. I normally end up adding 4 more tablespoons of water and sometimes the full 5, it’ll depend on how you measured your powdered sugar though.
• Beat until the icing is shiny, about 6-8 minutes with a stand mixer and 8-10 minutes with with a hand mixture. 
• The icing should be thick but not so thick you can’t stir it with a spoon. Adjust the constancy as needed. 
• When you aren’t working with your royal icing place a clean wet dish towel over the top of the icing so that it doesn’t start to harden. You can also press a piece of plastic wrap against the top of the icing. 

Notes

• You can have NO LEFTOVER GREASE in your bowls, on your spoons, or in your icing bags. I keep separate icing bags just for royal icing because buttercream is so hard to clean off the plastic. You can also have NO TRACE OF EGG YOLK if you are using egg whites in your icing. That little bit of fat, either from the yolk or leftover on your bowls will ruin the batch of icing and keep it from setting up properly. You’ll only make this mistake once!
• The goal for the icing is for it to be thick but not so thick that you can’t get it to pipe out of your bag. If it’s too thick you can’t work with it, and if it’s too thin it doesn’t work either. I go for an icing that I can stir relatively easy with a metal teaspoon but the spoon will also stand up in the icing in the bowl. 
• When you are ready to put your house together, put about 2 cups of your royal icing in a piping bag or a good quality freezer zipper-topped plastic bag. Use a frosting tip that is about ½ inch wide circle or cut about ½ inch off the tip of one corner of your baggie. If the hole is too small it’s really hard to get the icing to come out.
