This Easy Cookie Icing is a total game-changer for Christmas cookie decorating!
Since I love to bake and have made a career out of it, many people also assume that means I love to decorate. I actually learned a fair amount about cake, cookie, and pastry decorating in culinary school, but I have a big secret…
I actually hate decorating. Hate might be too strong a word – but seriously, I usually find it extremely tedious, boring, and pointless. It’s just going to get eaten and there’s nothing worse than people NOT eating something because it’s too pretty!! I guess I’m practical in that way.

Lately, however, some of my favorite bloggers have convinced me that sometimes making something beautiful is worth the extra time and effort. That doesn’t mean I’m not going to try to find a way to make it easier, though!

And that’s how I came to this method for Easy Cookie Icing. Royal icing may be beautiful, but it’s a huge pain and doesn’t even particularly taste good.
This easy cookie icing takes the same basic approach as royal icing. You make a thick border icing and then a thinner flood batch to completely decorate the surface of your cookies.

How to Make Easy Sugar Cookie Icing
How to Get the Perfect Consistency for Cookie Icing
This comes down to the powdered sugar:
- Be sure to use finely ground powdered sugar. Some brands are 5x ground and some are 10x. You want the latter to avoid any grittiness. For best results, use organic powdered sugar (which is made with tapioca starch) for a thicker, sturdier consistency and better flavor.
- Sift the powdered sugar first to make it completely smooth both in terms of texture and appearance.
- You will need to adjust the sugar and liquid to the right consistency for YOUR kitchen. Different brands of powdered sugar, different methods of measuring (cups vs. scale), water vs. milk, humidity, etc. will all affect how thin or thick your icing will turn out. Just keep adjusting the ratio until it’s right for you, adding a little more sifted powdered sugar to thicken, and a tiny splash more water/milk to thin.
How to get Perfect Cookie Icing Designs
You can always practice icing on a piece of parchment paper to test the consistency and to practice your decorating. You can even scrape the designs back into your bowl to avoid waste.
What Kind of Food Coloring is Best For Decorating Cookies?
I 100% prefer to use gel food coloring for icing cookies. Americolor or Wilton gel food coloring are my favorites. Gel coloring packs a powerful punch without adding extra liquid to the mixture. Start with just a drop of two and work from there.
How to Pipe Cookie Icing
Either squeeze bottles or pastry bags fitted with small plain tips. That’s all you really need! I personally prefer squeeze bottles as I find they’re easier to hold and handle, and you could even get the kids involved with those!
Do You Need Corn Syrup to Make Cookie Icing?
Nope, not for this recipe! If you want to add some to get that shine and more viscous consistency, start with a teaspoon.
Can Cookie Icing be Made Ahead of Time?
Yes! It can be made a day ahead of time and stored in a sealed squeeze bottle or resealable container. Remix or pop in the microwave very briefly until it’s workable again.
How Long Before Cookie Icing Hardens?
You kind of want to think of this icing like paint “curing.” It needs a full 24 hours sitting out untouched before it’ll be completely hardened enough to stack or transport without smearing anything.

For the border icing:
-
1
cup
(4.4 ounces) powdered sugar
(or more - see note), sifted
-
1/2
teaspoon
vanilla extract
-
2
tablespoons
water or milk
-
Gel food coloring,
if desired
For the flood icing:
-
1
cup
(4.4 ounces) powdered sugar,
or more, sifted
-
1/2
teaspoon
vanilla extract
-
3
tablespoons
water or milk
-
Gel food coloring,
if desired
For the border icing:
-
In a small bowl, use a fork to beat together all the ingredients except the food coloring. Beat in the food coloring, a few drops at a time, until colored to your liking. The mixture should be very thick but still pourable. Add more powdered sugar as needed.
-
Transfer the border icing to a squeeze bottle using a funnel. You can also scoop into a pastry bag fitted with a small plain tip. Before you begin icing any cookies, take a few moments to practice on a piece of parchment paper to get the feel of the icing.
-
Holding the bottle or bag tip directly over one corner of a cookie, begin tracing an outline of the cookie, squeezing gently and using both hands if needed to maintain consistent pressure. I prefer to allow a little slack in my icing line as I go. If you mess up, simply wipe the icing off and start again. Allow the icing to dry slightly before continuing with the flood icing.
For the flood icing:
-
In a small bowl, use a fork to beat together all the ingredients except the food coloring. Beat in the food coloring, a few drops at a time, until colored to your liking. The mixture should still be pretty thick, but will drizzle more freely than the border icing. If needed, add a splash of additional water or milk to loosen until the consistency is pourable. Or, add more powdered sugar as needed to thicken. Pour the flood icing into a squeeze bottle or into a pastry bag fitted with a small plain tip.
-
Prepare as many batches and colors of flood icing as you need to decorate your cookies.
-
Begin filling the interior of the border drawn on each cookie with the flood icing, being careful not to add too much that it overflows the border icing. Use either the nose of the bottle or a small toothpick to push the icing evenly over the cookie and up against the corners.
-
Leave the iced cookie to dry for 24 hours. The cookies are dry when the surface is completely smooth and resists smudging when touched. Store the dried cookies between sheets of parchment paper in an airtight container at room temperature for up to 10 days.
The amount of powdered sugar needed for the icing will depend on whether you use milk or water, the sugar brand used, and the humidity of your kitchen. Adjust until you get the desired consistency.
For best results, use organic powdered sugar, which is made with tapioca starch, for a thicker sturdier consistency and better flavor.
The iced cookies will need to dry for 24 hours before they can be safely moved or packaged without damaging the icing.
I can’t wait to get your book!!
We can’t wait to hear what you think of Tessa’s book, Linda! 🙂
I want to make Winnie-the-Pooh face. This is my first time using this type of icing. After the base layer of icing, how long do I need to wait to put the eyes, nose, and mouth on with an icing pen or more of this icing piped onto the cookie? Thanks.

Hi Rose! You’ll want to allow the icing to dry between layers, which, depending on your location, can take a couple of hours. I’d suggest using a gentle fan (lowest setting) to help speed up the process if needed. You could also create a “test cookie” where you can lightly tap the top to see if it’s dry enough (if it’s not, it may smudge, but this way you aren’t ruining your other cookies). I hope that helps!
Used the icing recipes yesterday and no problems.
I’d make 2 small batches – border and flood – and color them (flood being a bit lighter in color) and then use them. This took hours. My wife and I decorated 30 cookies and it took 6.5 hours to mix icing and bake.
I’d love to make one big batch of non-colored icing and then grab what I need and color it. The problem is the icing thickens and gets hard. How can we get past this?
Hi there! If your icing hardens too quickly, add additional water or milk to loosen the icing until you reached the desired consistency, about a teaspoon at a time. Make sure to keep the icing covered as well while it’s not being used as that can dry it out. I hope that helps!
This was VERY runny when made as directed. I needed about twice as much powdered sugar to make it usable.
Do you have to let it set in the fridge?
Can you tell me which funnel you use for the border icing in your video? Would love to order it. I think mine is too tiny for the thicker icing. Thanks!
This is A question. How do you store unused icing? In the refrigerator? How long can it sit out? Thank you!
The border icing recipe is entirely too loose to work with, you should really work on it before claiming to the entire world that it’s the best. Used it when I was in a pinch and out of egg whites, and it bled atrociously. Couldn’t get a good border unless I added almost three times the amount of powdered sugar you suggest. Again, tweak this. Not good.
I agree with Sarah. The icing was so runny. We added an extra cup of sugar to make it even a bit thick. Still not pipable.
Can you pre make, store icing? Having a cookie decorating party and really want to make add much add I can ahead of time.
Tessa, where can I find a “snowflake” cookie cutter. I want to make those with my grand children this year?
And, I see for this icing with the cookies you use food coloring, but for the different colored icing for decorating cupcakes with flowers, what do you use for coloring your icing? I read where using liquid food colors thins your icing too much and changes the taste. Can you advise me?
Love this site! Am planning and plotting a way to spend more time with my grandchildren. They love to decorate cookies and I want to introduce them to decorating cupcakes too. Am ordering things online to make it all easier. Any tips you ca share to help make this easier, what all I really need and how to cut costs, by not buying something I really don’t need?
This frosting looks pretty and is easy to work with but the taste is just not there for me. it’s just not a good flavor and i will never use it again on my cookies.
I just thought of another question,…..once the cookies are decorated and completely dry, do you think they could be frozen that way until you need them? I’d be making quite a few and being able to freeze them saves a lot of last minute work. Thanks again
I’m w/ you about decorating! Tedious and boring. But I might give it a try this year. I was wondering though does this icing dry shiny? If not, should I just add a few drops of corn syrup to the icing or completely replace the milk w/ corn syrup? Btw, I really enjoy this site and all the recipes and tips you share. Very nicely done! Thanks.
Hi Tessa, I would like to ask if doing the icing on cookies whereby we need to let it dry about 24 hrs, will the cookie turn soft ?
Hey Tessa! This is absolutely wonderful! But I am wondering… while I wait for my cookies to dry is it okay to just leave them out the way they are? Will the cookies get too hard or dry over that 24 hour period? Anyway, thanks for the great tips!
I love Christmas cookies! It just makes Christmas, well, Christmas!
I’m in the middle of editing the photos of mine.
Yours look amazing!
