What is royal icing?
Royal icing is an easy-to-make icing that’s made from just 3 simple ingredients: meringue powder, water, and powdered sugar. (Some recipes call for egg whites instead of meringue powder, but I prefer to use the powder because the results are more consistent and it’s safer to eat.)
As it dries, it hardens to the consistency of candy, similar to like button candy or a smarty. Hard enough to not smear, but not so hard you can’t bite it easily.
It’s perfect for piping on cookies. Pipe out your image, flower, or whatever, then set it out to dry for a few hours or overnight.
What makes this the best royal icing recipe
- Consistent results: You can count on this to work well, time and time again.
- Few ingredients: You only need 3 ingredients.
- Easy to make: It only takes a few minutes to whip this up.
- Versatile: It can be tinted and flavored with all sorts of different extracts.
What does royal icing taste like?
Royal icing mostly just tastes like sugar. It’s very sweet, and most meringue powders will also give it a subtle vanilla flavor.
You can jazz up the taste by adding lemon juice or any other kind of extract, but just be aware of how liquids can affect the consistency. Decorating with royal icing is ALL about the consistency!
Ingredients
Meringue powder: This ingredient can usually be found in craft stores, in the cake decorating section. You can also order it online: Meringue Powder. It’s safer to eat than raw egg white and it gives a more consistent result since the size of eggs can vary.
Water: To reconstitute the meringue powder.
Powdered sugar: Because it’s so finely milled, powdered sugar dissolves easily and ensures a smooth, lump-free icing. Granulated sugar won’t work because it’s too crystalline.
Special equipment
- Measuring cups and spoons: For measuring out the ingredients. Use this guide: How to Measure Ingredients for Baking.
- Mixing bowl: In which to mix up the icing.
- Electric mixer: A stand mixer or a powerful handheld mixer, fitted with the whip attachment.
- Gel paste food coloring: Optional, for tinting.
- Piping bags and tips: For applying the icing decorations to your baked goods.
How to make royal icing for sugar cookies
This recipe for royal icing comes together in just 2 simple steps.
Step 1: Dissolve the meringue powder
Place the meringue powder and the water in your bowl and give them a quick stir to get them combined.
Step 2: Add powdered sugar
Next, add the powdered sugar, and whip.
Start the mixer on a low speed, so that the ingredients don’t fly out of the bowl, and gradually increase the speed all the way up to high.
Allow the mixture to whip until it’s very stiff. It should hold a stiff peak.
Even if you prefer to work with a thinner consistency, you want to start it out stiff. You can always thin it out later.
How to tint royal icing
You can tint royal icing in all sorts of colors.
Use any kind of food coloring you like, but I have a strong preference for gel paste icing colors. They are highly concentrated, so not only do you not need much, but you don’t have to worry about them diluting the consistency.
How to get the right consistency
Like I said, when it comes to royal icing, the consistency is so important!
You want to start out by making your icing as stiff as possible. Whip it for a long time so it gets lots of air in it.
Then, scoop a little into a small bowl, and tint it with your icing colors.
Finally, thin it down to the consistency you need.
If you are making a gingerbread house, you probably want it to be very stiff so that it can hold the structure together. Same goes for piping roses or any other kind of flower.
If you are making a royal icing transfer or decorating cookies, it’s nice to have 2 different consistencies: one that’s pretty thin for flooding (or filling in), and one that’s a little stiffer for outlining.
The flood icing will sort of self-level. In other words, when you pipe it out, it will naturally spread and smooth over perfectly flat.
The outline consistency icing will hold the flood icing within its barriers, so it doesn’t spill over the sides of the cookie. You can also use it for accents here and there, to give the decorated cookies a little more dimension.
Stir a few drops of water at a time into the bowl of tinted cookie icing, until you get the thickness you’re after. If you’re not sure, take a peek at the video (in the recipe card) to see what flooding icing and outlining icing should look like.
Go really slow here and add the tiniest amount of water at a time. Once you’ve added it in, it can’t really be taken out.
As you stir, take up a spoonful of icing and allow it to drizzle off the spoon. Look carefully at what it does as it falls into the bowl.
Does it immediately disappear into the puddle of icing? Or does it hold its shape for a few minutes and then melt?
The picture above shows a good consistency for flooding. It’s thin enough that it melts into the puddle after a few seconds, but thick enough that it will stay on the cookie without running over the sides.
How to dry royal icing
Once your royal icing has been piped on, you can set it out to dry. After just 15 to 30 minutes, it will form a thin crust on the surface, but it generally will stay wet underneath for several hours.
I usually set my cookies out (in a single, flat layer, on parchment-lined baking sheets) overnight to dry. They won’t get stale that quickly, because the royal icing actually serves almost like a barrier from the air.
I would not recommend drying royal icing in the refrigerator or freezer. The humidity levels can be funny in there, so room temperature is best. If you need to speed up the process, just set up a fan nearby.
How long will it last?
Royal icing really won’t ever spoil, because the sugar content is so high that bacteria can’t grow. It’s really a lot like candy. But having said that, you will notice the quality will degrade over time.
After 24 hours, the royal icing will become more thin and watery. You can thicken it back up with a little more powdered sugar if needed.
After 36 hours, it may start to separate. You can stir it though, and it will come back together.
After about 48 hours, you might start to notice a grainy texture. I don’t think there’s any way to recover it from that state, so I generally try to either use up or throw away any leftover royal icing after 2 or 3 days.
Can you freeze it?
I probably wouldn’t recommend freezing leftover icing, since it’s so easy to just make a fresh batch, and fresh is always best.
However, if you want to make and decorate your sugar cookies ahead of time and keep them in the freezer until they’re ready to be eaten or gifted, you absolutely can.
I’d suggest placing decorated sugar cookies (completely dried) in a single layer in an airtight container, with sheets of parchment in between each layer. This way, if the color bleeds at all, it won’t mar the other cookies above it.
And when you are ready to thaw, take the lid off and make sure there’s lots of airflow around every cookie. So any condensation that may occur doesn’t disturb the design.
Can I make this recipe with real egg white instead?
I don’t like to do it this way, but it is possible.
You can use 3 large egg whites in place of the meringue powder and water, or about 120 grams of egg white.
Expert tips
Keep it clean: I like to reuse my piping bags (even the disposable plastic ones sometimes), so I included a little trick in the video below that makes cleanup a snap! Basically, you just enclose the icing in plastic wrap before placing it into the piping bag. That way, when you’re done you can just slide out the wrapped-up icing, and you really only have to clean your tips.
Close it tight: I also like to twist the end of the bag and secure it with a rubber band or twisty tie. It keeps everything together nicely and if any cookie icing comes up the top, it doesn’t harden and scatter dried icing crumbs everywhere.
Wet the end: If you’ve ever used royal icing before, you may remember feeling frustrated when it hardens at the tip. It only takes a few minutes for the icing in the little pinhole of your piping tip to harden, and then you can’t squeeze it out at all. You can break it up with a toothpick, but then sometimes you’re forcing hardened icing into your tip and creating a clog. So, try placing a damp towel in the bottom of a drinking glass, and keep your bags (tip side down) in there. That little bit of moisture in the paper towel will prevent those clogged tips from happening.

Can I use a stiff constancy of royal icing to pipe out names on chocolate lollipops?
And how long I advance to the bridal shower can I pipe them?
Also how would be best to store them ?
Thanks! 🙏🏻
I can’t imagine why it wouldn’t work?? The further in advance you pipe them, the more time they’ll have to dry and harden. Good luck!
Does this icing dry dull? I don’t see any Karo syrup or glycerin so how do you get the shiny look?
It dries with a matte finish.
I found a trick for rolling cookies with all cookies having the exact same depth by creating a ‘rolling alley’!!
Place parchment paper on your rolling surface. Tape 2 paint mixing, wooden strips (with a width of your rolling pin minus 1/2”). over the parchment paper (make sure they are taped to your rolling surface and not the paper). Put a portion of your dough in the center between the paint sticks and place a piece of parchment paper over the whole shebang. Keeping your rolling pin on the wooden slats, roll out your dough. Want a thicker cookie? Tape two paint sticks together for each side of your rolling surface. Perfect cookies every time!!
Is there a concern that leaving them out overnight will cause the cookie to be stale?
I have not really had that problem with any of my cookie recipes.
Hi! I made this recipe and it worked as described. Only issue is that it tasted incredibly chalky! Like inedible. I researched and it could have been over mixed, but I followed your instructions exactly! What speed do you use at each stage of whipping? Do you try to not mix the colours in that much? Any thoughts or tips? I’m needing to get the next batch just right the first time for a virtual baby shower. Thanks!!!!
Sorry to hear you had trouble! I typically mix it quite a lot. As noted in the recipe directions, I do it on medium speed until the icing holds a stiff peak. The color just gets mixed in until incorporated. You can see what the consistency looks like when you watch the video (embedded in the recipe card).
Thanks for the reply. When you say medium what number on your mixer is it? The video looks like you clicked it into the second gear. Is this right? Just don’t want to waste more ingredients. Can you also say about how long you beat the comb with the sugar to get stiff peaks? Thanks.
My mixer doesn’t have numbers on it- I just switch it so it’s about halfway. It probably needs to whip for at least 5 minutes. If you’re having trouble getting it to stiff peaks, make sure your bowl and whisk don’t have any traces of grease- this will prevent meringue from whipping properly. Good luck!
I bake sometimes to clear my head in these time and i ran into your website when i was looking for a bread recipe using wholemeal flour and from there i keep at least checking your recipes when i’m fancying trying a new thing.
And i’m writing just to say that what really sets you apart from other sources i have seen is that you advise times for mixing and whisking and even mention the prefered speed at times! For the latter i would love it if you cold specify that even more in other recipes as well!
Mostly i seen recipies going kinda like “just do it until mixed well”! And God please believe me i’m not even confident at knowing this so i’m always afraid ending up over-mixing or not mixing enough!
Thanks for the great feedback, I will definitely try to keep this in mind!
Consistency was horrible if you’re thinking of writing names.
Please be sure to whip the icing until it holds stiff peaks, as noted under the heading “How to get the right consistency,” as well as in step 2 of the recipe directions. Also, if you’re looking for a stiffer consistency, then don’t thin it with additional water.
Thank you for this tutorial! I have a hard time working with royal icing and I feel confident my next attempt with go more smoothly after reading this post!
You’re welcome! Thanks for the excellent feedback!
Is it possible to use royal icing as glue for butter cookie structures? I made a colossal mess back in the last century and haven’t tried it since!
I can’t imagine why not? It works well for gingerbread houses so I would think you could do the same for any type of cookie. Good luck!
What’s the best number tip used for outline and the number tip use for filling. Can I use the same tip number for outline and filling. Thanks Kristin
It all depends on the design you’re trying to create. You just want to choose the best size tip for the image you’re making… it doesn’t matter if you use the same one for outline and filling, as long as it gets you the look you’re after.
Just discovered your site today. Am very impresses with your complete information, tips and processes included with each recipe. Truly showing patience and sharing knowledge of tips and processes not necessarily known by everyday cooks such as myself. Thank you for showing how to line pans for lemon bars, etc; how to thin royal icing; using regular royal icing as an outline to “fill”. Your recipes include the methods to produce recipes from my kitchen that not only taste good but also look well done the very first time you attempt the recipe. Thank God I found you!
That is so nice to hear Tina! I’m so happy you’re enjoying my content. This really means a lot to me!
Allie – can you add extract flavoring to the icing recipe?
Hey Dawn! You can, but usually the meringue powder already has vanilla flavoring added, so just keep that in mind. Good luck and enjoy!
Very nice recipie. Love it
So happy to hear it. Thanks Veronica!
Unfortunately I cannot get my whisk to make this amount because it’s too small it seems. My whisk just skims over the top of it all. I have a kitchenaid pro, so maybe the bowl is deeper? I’ll need to double the recipe I think! I typically mix it by hand, so I was curious to try this method but it doesn’t seem to be working as well for me
If you look under the top part of the mixer, you should see a screw. Turning this screw will raise/lower the whisk. I think that should help bring the whisk down to the level it should be at. Good luck!
Thank you for that tip! I’ve had my Kitchen Aid for…ahem…….FIFTEEN YEARS and never knew about the screw adjustment! I made this icing yesterday and had a similar issue just initially with the meringue powder/water, so I stopped it a few times and just whipped that together with a hand whisk; once I put the sugar in, there was enough volume for the whisk to catch and pull everything off the bottom. This will be so helpful for next time, though!
So glad I could be of help!
If I want to make the cookies 4 to 6 weeks ahead of time can I freeze them or is that just not possible with royal icing?
You can try it, but there’s a chance the colors could run after the cookies have thawed. It would probably be better to save the decoration until a few days before you plan to serve the cookies. Good luck!
Can I add any vanilla extract to the icing to flavor? If so, how much?
Most meringue powders already contain vanilla flavoring, but you can certainly play around a little bit if you’d like.
What a perfect icing! Thank you for sharing the recipe, video and tricks. I just had a hard time trying to get dark brown with a fluid consistency but it took so much water and dried uneven. It was a figure with many colors and dark brown the largest part of it. It worked for the other colors though… Could not find out what went wrong with dark brown, mabe to much gel colors to get it dark… I’ll definetely try your recipe!
I tried this, the icing never set completely hard, I am not sure what I did wrong
I cannot seem to get the flooding consistency. About how much water from the original recipe do you add to reach flooding? It takes me a lot of water to get there and then I have an issue of the royal icing never drying although the cookies look good, it doesn’t dry.
The amount of water needed can vary quite a bit based on your environment. It could be anywhere from a few drops to a tablespoon or more. It will usually take at least 8 hours for the icing to dry- and it could need even longer if it’s a very humid day.
Attn: Allie – Can you please remove my previous comment with my full name; I didn’t realize that would be posted….
Thank you for your awesome recipes! I’m going to try making the Vanilla Cutout Cookies that don’t spread with royal icing for my sons party! I’m just worried about how to make/store them prior. I understand that I should not put a completed cookie in the freezer/fridge because you mentioned that the icing should be left at room temp. Being a beginner, I want to give my self sometime to do steps so it’s not so overwhelming. But at the same time, I dont want stale cookies (especially if I’m giving them as favors). If a party is Saturday – when is a good time to start and what would you do if it were a party? Would you start say – Wednesday? How long can a completed (with royal icing) be good for if left out? Do you have information on this (how to properly store, etc.)? Thank you!
No problem Chelsea, I’ve deleted your previous comment so your last name will not display. To answer your question, I think if you start on a Wednesday you should be good for a Saturday party. There is no need to put them in the freezer or fridge. The icing will “seal” the cookies and keep them from drying out. Once the icing has hardened, you can pop them into zip top bags or an airtight container, and they should stay good for a few weeks at least. Good luck!
Hi – wondering if you use the same tip for piping and flooding?? I see that the consistency in the icing is changed but can you use the same tip? Thank you!
It doesn’t matter what tip you use. Use whatever tip you need to create the design you’re after.
