This fluffy gingerbread house icing is the only icing I use to build and decorate our houses every December. I’ve made countless batches over the years for our annual gingerbread house parties, and it works so well! It’s made with just three ingredients, pipes beautifully, and dries hard enough to hold walls, roofs, and plenty of candy in place.
Use it for gingerbread houses, mini gingerbread houses, gingerbread Christmas trees, and gingerbread cookies.

Why This Gingerbread House Icing Works
Dries hard: It sets firm enough to hold walls, roofs, and plenty of candy in place.
Easy to pipe: The thick, fluffy texture holds its shape exactly where you pipe it.
Makes plenty: One batch makes about 3 cups, enough for 2 to 3 standard houses or 6 to 8 mini houses.
Gingerbread House Icing Ingredients
Powdered Sugar: Also called confectioners’ sugar. This is what makes the icing thick enough to pipe and eventually dry hard.
Egg Whites: Give the icing its structure and help create that thick, fluffy texture. If the house will be eaten, I prefer pasteurized egg whites.
Cream of Tartar: Helps stabilize the whipped egg whites so the icing holds its structure.
How to Make Gingerbread House Icing
1. Beat the egg whites: In the bowl of a stand mixer, with the whisk attachment, beat egg whites and cream of tartar on high speed until stiff peaks form.
2. Add the sugar: Turn the mixer to low speed and add powdered sugar one spoonful at a time.
3. Finish the icing: Once all of the powdered sugar is in the mixer, turn it to high again and beat until the icing is fluffy.
Test it: Pull a knife straight through the icing. The line should stay open and not run back together. That’s how you know it’s ready to hold a wall.
How to Know It’s the Right Consistency
This is the most important part of the recipe. Gingerbread house icing should be much thicker than icing you’d use to decorate cookies.
Too runny: The line from the knife test closes back up. Add powdered sugar a little at a time.
Too thick: It’s difficult to squeeze through your piping bag. Add water 1 teaspoon at a time until it’s pipeable.
Just right: It holds a stiff peak, the knife line stays open, and it pipes easily without spreading.
How Much Icing Do I Need?
One batch makes about 3 cups of icing, or roughly four small piping bags. The exact amount you’ll need depends on the size of your houses and how much decorating you plan to do.
- Standard gingerbread houses: 2 to 3
- Mini gingerbread houses: 6 to 8
- Graham cracker houses: 4 to 5
If you’re hosting a gingerbread house party, I always make extra. The recipe doubles or triples easily, and I’d much rather have leftover icing than run out halfway through decorating.
Easy Way to Fill a Piping Bag
A friend taught me this years ago and I’ve never filled a bag any other way since.
- Grab a tall glass or jar with a wide mouth
- Set the piping bag inside and fold the edges over the rim
- Spoon the icing in, pushing it down as you go
- Fill about three quarters full, then lift the bag out
- Twist the top and secure it with a rubber band
How to Use It to Build a House
- Whip the egg whites: Add 4 large egg whites and 1 teaspoon cream of tartar to the bowl of a stand mixer fitted with the whisk attachment. Beat on high until stiff peaks form.
- Add the powdered sugar: Turn the mixer to low and slowly add 4 cups powdered sugar, one spoonful at a time.
- Whip until fluffy: Once the sugar is incorporated, turn the mixer back to high and beat until the icing is thick, glossy, and fluffy.
- Check the consistency: Pull a knife straight through the icing. The line should stay open instead of running back together. If it’s too loose, add more powdered sugar, up to the additional ½ cup, a little at a time.
- Color if desired: Divide the icing into bowls and tint with a small amount of gel food coloring.
Full step by step is in my gingerbread house recipe, including the dough and the templates.
Eden’s Tips
Fill the piping bags right away. Once the icing is ready, I spoon it into piping bags and close them up so the icing isn’t exposed to air. Royal icing starts to crust as it sits, so keeping it sealed in the bags keeps it fresh and ready to use when we build and decorate.
Use gel food coloring. Liquid coloring can thin the icing. Gel gives you beautiful deep colors without changing the consistency, and you only need a tiny amount.
Build first, decorate later. I usually assemble our houses the day before a party and let the kids do the fun part the next day. Nobody has the patience to wait for walls to set and then decorate!
Skip the icing that comes in the kit. Even when I buy a boxed gingerbread house kit, I make this icing instead. There’s never enough icing in those little packets; it never holds the houses, and squeezing it out is usually a wrestling match.
Making houses with little kids? Graham crackers are great, and a small milk carton or box can act as support inside the house.
If Your Icing Isn’t Holding
- The whites weren’t whipped enough. They need to hold genuinely stiff peaks before the sugar goes in. Under-whipped whites make a loose icing that no amount of sugar quite fixes.
- There’s not enough sugar in it. Add more, a quarter cup at a time, until the knife test passes.
- It’s humid. Damp weather means more sugar. Just keep adding.
- You froze it. Frozen icing loses some structure on thawing. Bring it fully to room temperature, re-whip, and add a little powdered sugar to bring it back.
- You’re rushing the set time. Walls need 15 to 20 minutes before the roof goes on. Every single time.
Storage
Room temperature. Sealed piping bags or an airtight container will hold overnight. Make it the day before a party and let it come back to room temperature for a couple of hours before you use it.
Refrigerate. Up to three days in an airtight container. It firms up in the cold, so it needs a few hours out and usually a quick re-whip.
Freeze. Up to three months. Thaw in the fridge overnight, bring fully to room temperature, then re-whip. Expect to add a little powdered sugar to get it back to glue consistency.
Gingerbread House Icing FAQs
Yes, as long as you use pasteurized egg whites. They come in a carton in the dairy aisle and they whip up just like fresh. Fair warning though, royal icing dries rock hard and doesn’t taste like much once it sets. It’s glue first and dessert a distant second.
You can, but I don’t. I’ve made this with egg whites every year for as long as I’ve been building gingerbread houses and it’s what I trust. If you’d rather skip raw eggs entirely, use pasteurized egg whites from a carton. They whip up exactly the same and they’re completely safe to eat.
It’s set to the touch in about 30 minutes. Walls are stable enough to add a roof after 15 to 20 minutes of holding. For a house that’s truly rock solid, give it overnight before you start piling on candy.
Pipe a thick line of this icing along the edges, press the pieces together, and hold for about 60 seconds. Thick lines, not thin ones. This is where most houses fail.
Yes. It stabilizes the egg whites and keeps them from deflating while you build. It lives in the spice aisle at the grocery store.
Absolutely. Make it the day before, store it in sealed piping bags or an airtight container, and let it come back to room temperature before you build.
Gingerbread pieces or graham crackers, this icing, piping bags and tips, a lot of colorful candy, and a sturdy base like a cake stand or a pretty platter.
Yes, and I’d recommend it. Use the kit for the gingerbread pieces and candy, and make this icing instead of the packet that comes with it.
I wouldn’t. Buttercream stays soft, while this royal icing dries hard enough to hold the walls and roof in place. Save the buttercream for the cake!

Question:
Sounds like a great recipe from the reviews and I’d like to use it. But, can this frosting be made in advance? How would you store it if made ahead of time?
Thank you!
The best icing for building a gingerbread house. Hardens very fast and holds its form. Highly recommend.
How long does this frosting last once applied? At what point do you think it will be bad? Days? Weeks?
It honestly stays a very long time! I toss them after Christmas, but it doesn’t go bad, and I think it would last another 3 months!
How much meringue powder do you substitute for the egg whites
Hi Barbara, I haven’t tested this! Bit, maybe try one and see if that works. If not add another.
how much does your recipe make? How many piping bags would this fill? I’ve got 10 gingerbread decorators and they’ll each need their own piping bag. Just wondering how many batches I’ll need to make. thanks!
You will get about 4 small piping bags. You can double the recipe to fill more.
This is the very BEST icing I’ve ever used. So soft, creamy and stiff yet extremely easy to pipe and hardened quickly and beautifully! I’ll never use anything else. Thank you for this awesome recipe.
Isn’t it the best!! It works SO well and it’s so fluffy. We use it several times a year! I am so happy it worked for you!
I had a gingerbread decorating party for 7 kids aged 7-9. This was perfect for decorating and easy for the kids to work with. The flavor wasn’t important for this project so it’s a 5 star recipe.
Yay! So glad you liked it Diane! We use it every year and it works SO well!!
I haven’t made this yet, but was wondering how much should I use to frost 24 cookies?
Hi Ashlee, this recipe is for gingerbread house. I wouldn’t recommend it for cookies.
I just made this last night for an Easter-themed house. In south Louisiana, it’s quite humid and it was made even more so by 5 straight days of rain. (Yes. Really. Non-stop rain.) Even so, I made this recipe, added a little more powdered sugar due to the humidity and it was AMAZING. I was a bit nervous because it seemed so soft, but it piped like a dream, held color beautifully, and it really held that house together! Even with the humidity, I left the roof go after only 30 seconds and it stayed!
The frosting was so supply and pliant, that we actually used it like buttercream for some areas, but it hardened like a rock and it didn’t take that long. I will never use any other icing but this. Thank you!
Thank you for this beautiful review Meagan! What a cute idea to make an Easter themed house too! There is much fun Easter candy to decorate with!!
I was wondering how far ahead this recipe can be made and how long it could be stored? It looks so good can’t wait to try!
Hi! The icing can be made a few days ahead but has to be stored completely sealed or it will dry out. It also needs to be brought back to room temp before using. I do like it fresh better as it’s the perfect consistency.
