In this post you’ll also find several examples of consistencies used in real cookie projects. In my video you can see the fluidity of icing from stiff to 4 second consistency.
HOW TO THIN ROYAL ICING?
But how do decorators create smooth royal icing finish on their cookies?
To create a smooth royal icing finish we have to thin stiff royal icing with room temperature water to more fluid consistency.
To create a smooth, satin like royal icing finish we have to use icing that is fluid enough to cover surface of the cookies with a thin, smooth layer of icing.
Use water at room temperature. Tap water is fine. Avoid using chilled or hot water.
Though you can use a spoon or a dropper to add water to icing I recommend using a Spray Bottle.
I learned this tip from a seasoned decorator One Tough Cookie. Gail is no longer decorating cookies but her clever spray bottle spritz method is still going strong, being used by hundreds of cookie decorators.
Why Spray Bottle Works?
Spray bottle allows you to easily control the amount of water you add. Too much water added at once can yield to icing that is too runny. And runny icing can be difficult to work with.
When thinning royal icing with water add small amounts of water at a time. Whisk well, check the consistency and repeat if necessary. Little water goes a long way.
STIFF ROYAL ICING
What does this consistency look like?
When you first make royal icing it should be thick with a stiff peak. Royal icing with a stiff peak doesn’t spread. It stays in the shape you pipe or shape it. You can shape stiff royal icing with a palette knife, fork, decorating combs or with a toothpick.
STIFF ROYAL ICING USES :
- Piped flowers such as roses, succulents, leaves, pressure piped decorations
- Glue/cement for building gingerbread houses.
- Use it to create different textures, for example brick, wood grain, scales, use decorating combs to create fun textures.
- Beaded borders or brushed embroidery.
- Use it with stencils to create beautiful patterns, messages on cookies.
- It works great with specialty piping tips to create beautiful life like patterns, such as basket weave or grass.
- How to make Succulents
- 3D Easter Egg Cookie Baskets (basket weave)
- Holiday Gingerbread Birdhouse (wood grain)
- Nightmare Before Christmas Gingerbread House (roof)
- Love Shack Gingerbread House (roses)
- Mermaid Gingerbread House (sea shells)
- Graduation Cookies (tassel)
- Easter Gingerbread House (roof)
When using royal icing with stencils it is best to use thicker icing. Thin icing can leak underneath of the stencil.
- Beauty and the Beast Gingerbread House (roof rose pattern is stenciled)
- Dipped Marbled Cookies ( leaves and roses are stenciled)
- Butterfly Cookies
PIPING CONSISTENCY
What does this consistency look like?
Icing when pulled up with a spatula it forms a peak that slowly falls down. It’s flexible and soft but doesn’t become blended with the rest of the icing.
Piping / Outline consistency is used to create piped details on cookies. Such as writing, fine details, outlines and so on.
- Jiff Peanut Butter Cookies (outlines)
- Skull Cookies (black outlines)
- Pink Snowflake Cookies (white design)
- Dragon Fruit Cookies (black outlines)
FLOOD ROYAL ICING CONSISTENCY
What does this consistency look like?
Flood consistency refers to consistency that when used to decorate it results in a royal icing with a smooth, satin like finish.
Flood consistency royal icing is often referred to as 5, 10, 15 or 20, 25 seconds icing.
Seconds refer to the time it takes for the icing to become smooth after you run a spatula through it. Or you can take a spoonful of icing from a bowl and let it fall back into a bowl. Count how long it takes for the icing to become smooth again.
For example when you run a spatula through icing, it may take 20 seconds for the line to disappear. If you only need 15 second consistency this simply means you need to add little more water. And vice versa.
Depending on the project, size of the cookies, your skill, different flood consistencies can be used to achieve desired look of smoothly iced cookies.
4 SECOND ROYAL ICING CONSISTENCY
I use it to brush a thin layer of icing on cookies. This is especially useful when creating depth. This icing can also be use to create windows panes, eyes.
- Pumpkin, Vampire Cookies (black sections)
- Cookie Monster (mouth)
Notice black sections are sitting lower than the rest of the icing around it.
10 SECOND ROYAL ICING CONSISTENCY
Works great for Dipping Icing Method, general flooding, and icing larger cookies, for example gingerbread house panels.
- Star Wars Gingerbread House (roof)
- Pink Marbled Sugar Cookies (dipping method, gluten free sugar cookies)
- Marbled Dipped Hexagon Cookies
15 SECOND ROYAL ICING CONSISTENCY
In my YouTube instructional cookie decorating videos you may have heard me say “use 15 Second Consistency Royal Icing” more times than I care to count.
I mostly use 15 second royal icing consistency to flood the cookies. Slightly thicker than 10 second, it doesn’t spread too fast and works great for both : outlining and flooding the cookies.
- Pot of Gold Cookies (black and rainbow)
- Captain America Shield Cookies (red,white, blue base, star is 20second)
- Purple Heart Cookies (purple base)
- Yellow Cherry Mixer Cookies (yellow base with cherries and leaves)
- Witch Hat Cookies (blue and orange)
20 SECOND ROYAL ICING CONSISTENCY
I use this consistency to create tufted, puffy designs. It’s ideal for flooding of smaller sections. And it’s also great for adding dimension to a design.
- Soccer Ball Cookies [Template] (white and black is 20 sec)
- Succulent Cookies (borders are 20 sec)
- Dinosaur Eyes Cookies (eye lids)
- Pizza Cookies (cheese, pepperoni, peppers, olives)
- LOL Surprise Doll Cookies (dolls eyes)
WET ON WET DESIGNS
10 and 15 second royal icing consistencies, both are great for creating fun wet on wet designs. For example : marbling, wet on wet roses, polka dots, bubbles, animal prints and so much more.
- Espresso Cup Cookies
- Tomato Cookies
- Dragon Fruit Cookies
- Purple Marbled Cookies
- 3D Dinosaur Cookies
- Flower Cookies
- Heart Cookies
- Mushroom Cookies
SHOULD I USE PIPING BAGS, DECORATING BOTTLES, PARCHMENT CONES OR SANDWICH BAGS TO DECORATE?
To apply royal icing onto cookies you can use sandwich bags, piping bags, decorating bottles or parchment cones. These all can be used to pipe the royal icing.
Which you use is entirely up to you. I used sandwich bags for years before switching to disposable tipless piping bags. I think most people use piping bags.
When using a piping tip it’s definitely a good idea to use a piping bag.
There are quite a few decorators using piping bottles, too. During one of the classes, student told me that she prefers to use bottles as they cause less strain on her wrists. So, it’s definitely something to consider.
Use what feels the most comfortable for you. Be mindful of your body and if something is causing you pain try to modify either consistency or tools you use.
IT’S SO CONFUSING, I HAVE NO IDEA WHAT ROYAL ICING CONSISTENCY TO USE?
If you are beginner then this all can seem overwhelming. No need to panic.
Start with one or 2 consistencies : 15 Second consistency to flood and Piping consistency to add some piped details.
If you don’t want to invest into piping bags right away or don’t have any on hand try using sandwich bags.
- Start by flooding cookies with 15 second consistency.
- Let the icing dry.
- Then use a piping consistency royal icing to add some details.
- Or have fun with wet on wet designs : make polka dots, flowers, hearts, leopard print.
As you learn some basics about how royal icing behaves it will be much easier to determine what royal icing consistency to use for a project.
FLOOD CONSISTENCY ISSUES
- My royal icing is too thin? Add more stiff royal icing. Or you can also add little bit of sifted powdered sugar : 2tbsp per cup of icing.
- Icing starts to crust too fast. This can be caused by : ambient temperature (if you work by a heat source) or accelerated air circulation (fan running close by). Or perhaps your icing is too thick, or you haven’t yet developed a skill to flood quickly. It’s normal.

Love your website, work & ideas! Please recommend a good airbrush. Thank you!
Hi Mary,
thank you.
As far as an airbrush goes, there are several on the market that are reasonably priced and work well.
Cookie Countess Airbrush System on cookie countess website
AirGenie Basic Airbrush Kit on creative cookier website
I use Master Airbrush Cake Decorating Airbrushing System (amazon). I’ve had it for years, and it works great but it’s not very compact, so if you are looking for something smaller in size I’d go with the ones I mentioned above. Hope that helps.
I want icing that is not matte. Tried fan and it works. Just read where put decorated cookies in the oven on 170 degrees for 30 minutes. I experimented with a few cookies and I was amazed. Have you heard of this. Is this recommended?
Hi Linda,
yes, fan helps to promote quicker drying. Yes you can also dry them in the oven, just be sure not leave them in there for too long as it can dry out cookies. I usually do 10 minutes to get a quick crust on it. You can also use oscillating, portable heater to dry icing quicker, resulting in shiny royal icing finish.
What consistancy is best for stencils?
Hello Selina
in my experience thick icing works the best, it doesn’t have to be super stiff but thicker the better. If it’s too runny you are risking it will leak underneath of the stencil.
Hi Hani! I was watching one of your videos showing how to make 3D Christmas Stockings Cookies. I notice that your royal icing is so shiny in the video! May I please know how you make it shiny? Mine turns matte in color after the icing dries 🙁 Also would you be able to recommend a good airbrush to buy?
Thanks you for your time reading my comment,
Regards,
Jc
Hi Jc,
I find that when icing dries fast it maintains a nice shine to it.And also it depends on the meringue powder you use and what is an actual dry egg white ratio in the mix. My advice would be to try speed up drying process by employing fans.
WOW!!! Thank you so much for all the examples and information! You are AMAZING? Love your webpage and work…
Thank you so much.
Hi, the video doesn’t have any sound. I’ve watched it on several different internet browsers and the sound doesn’t play on any of them.
Hi Peggy, video on the blog plays without sound. You can view this video in full and with narration on my youtube channel. Ultimate Guide to Royal Icing Consistency video with narration.
Hi haniela
How do you get icing red red like you do?? What do you mix? Thanks. Love your decorating
Hello Elizabeth, when starting with white royal icing I add Super Red gel food coloring by Americolor brand until icing turns dark red with a pink hue. Let the colored icing overnight and best for couple of days at room temperature. As the colored icing matures its color get richer. After this if your icing is not desired red color you can add little more food coloring.
Any recommendations for dye free red coloring. The once’s I have tried do no come out red but nor dark pink😩
Hi Karin,
you can try freeze dry fruit, for example red beet, or red raspberries, pulverize them and use to color icing. However, with natural colors it can be difficult to achieve a true red color.
Hi Haniela!
I loved your explanation! It’s very simple to understand. When I decorate my cookies, craters appear on them. I don’t know what I am doing wrong…. can you help me?
Hi Isliana, thank you. Try to use thicker icing.
What is your technique for cutting the tipless piping bags? How much do you cut? Do you cut on angle? I get mixed results, sometimes icing will squirt out slightly sideways, etc. Any tips would be helpful! Thanks
Hi Vikki,
I show how I cut the tipless bag in the video in the post, at about 2:40.
Find the seam, flatten it in the middle, cut straight. Then, most like you might need to shape the opening so it’s not flat from the task before. Hope it helps.
