This smooth and glossy Sugar Cookie Icing is super easy to make in just 15 minutes! It hardens on top of your cookies beautifully, and it tastes as good as it looks. I recommend using my simple cut-out sugar cookie recipe with this icing!
You really can’t buy the kind of icing that hardens at a store. This type of icing must be homemade, and most versions of it are royal icing recipes. While I love my fool-proof royal icing, sometimes I want something a little less finicky, especially if I’m not trying to decorate my sugar cookies with a super intricate design.
While royal icing requires whipping, this simple alternative takes 1 minute to mix together. After that, you just have to color it! If you need a quick-fix icing for cute little cookie designs like snowmen, candy canes or Christmas trees, this recipe is the way to go.
And it’s not just a decorative topping – it also tastes delicious! You can make a classic vanilla version or switch it up with another flavor of choice. Either way, your cookies are about to get an upgrade.
Ingredients You’ll Need
You only need a handful of kitchen staples to make this icing happen. Just gather up the items below!
- Powdered Sugar: As with any icing or frosting, powdered sugar provides the base.
- Light Corn Syrup: To give your icing that shiny finish.
- Vanilla Extract: Feel free to switch it up with almond extract or another favorite.
- Milk or Water: This will thin out the icing.
- Gel Icing Color: I recommend Wilton or Americolor gels. The nice thing about Americolor is that they come in little squeeze bottles, which makes it easier.
What Can I Use Instead of Corn Syrup?
You only need a little bit of corn syrup to make your icing nice and glossy. But if you really don’t want to use it, you can substitute it for honey instead. Honey will impart a different flavor on the icing though.
Let’s go over the process of making this icing step by step. It’s simple from start to finish!
Combine Ingredients: Add the powdered sugar, corn syrup, vanilla extract and 3 tablespoons of milk or water to a medium-sized bowl. Whisk together until everything is well combined. It may seem dry at first, but it’ll come together.
Adjust Consistency: Add additional milk or cream to get the right consistency (see section below).
Add Color: Divide the icing into as many bowls as you need for the colors you want. Stir in the gel icing color a little bit at a time until you have your desired shade.
Decorate Cookies: Add the icing to squeeze bottles or piping bags with small round tips for piping.
Let Set: Allow the icing to dry. Give it at least 4-5 hours to fully harden before stacking.
There are two typical icing consistencies when it comes to decorating cookies – one for outlining things and one for “flooding” and filling in the outline. I like to bring my icing to a sweet spot that works for both! With just one consistency, you have fewer bowls of icing and fewer piping tools to deal with.
To get your icing to the sweet spot, you need it a little thinner than you’d use for outlining, but not so thin that it won’t hold in place. If you’re unsure what that looks like, there’s an easy way to test it out – once you mix everything together, pick up some icing with a spoon and drizzle it back down into the bowl. It should take 3-4 seconds to fully integrate back into the icing.
Once you have the tops of your cookies covered in icing, you’ll have to let it harden before doing any detail work with additional icing. Either let the cookies sit for 4-5 hours or leave them in an airtight container overnight. If you’d like to add sprinkles on top of the icing, do so before it sets.
Tips for Success
If you’re new to homemade sugar cookie icing, this recipe is the perfect place to start. These extra tips and tricks will help you become a pro in no time!
- Avoid Liquid Food Coloring: I recommend sticking with a gel-based food coloring for this particular icing. Liquid-based food colorings tend to mess with the consistency because you have to use a good bit to get deeper colors.
- Add Small Amounts of Milk at a Time: You need the right balance between powdered sugar and milk (or water) to get the proper frosting consistency. Start with just 3 tablespoons and add more little by little as needed. You can always add more, but you can’t remove it once you add it.
- Don’t Have Piping Tools? While piping tools or squeeze bottles make the decorating process more simple, you really don’t need them at all. You can simply transfer your icing to a Ziploc bag and cut a small hole in the corner of the bag to squeeze the icing through. Alternatively, you can spread it on with a knife or an offset spatula.
- Toothpick Trick: If you’re piping the icing onto your cookies, you can use a toothpick immediately after doing the piping to fill in little gaps, help get rid of air bubbles, or scrape off little bits of icing that aren’t doing what you want.
Storage Instructions
If you have leftover icing that you’d like to use for future cookies, you can store it in an airtight container in the fridge. Bring it back to room temperature before using it, stirring in a little more milk or water if needed. Use leftover icing within 1 week.
Can I Freeze Powdered Sugar Icing?
I don’t suggest freezing this icing by itself – you’ll have trouble getting it back to the right consistency after thawing it. However, if it’s hardened onto cookies, you can certainly freeze them if you’d like. Just don’t keep them stored for longer than 3 months.

More Easy Frosting Recipes
Want more simple homemade frostings to add to your favorite sweets and treats? I’ve got you covered.
Hi again! I need to make these ahead of time (around a week and a half). Is it ok to freeze them or should I refrigerate them instead? Thanks so much!
The only caution for freezing is that when they thaw, condensation can form and sometimes the colors bleed. If the decorations are simple and don’t use sprinkles, they might not have any issues. They could possibly bleed a bit if they sit in the fridge that long. You could honestly just leave them in an air tight container at room temperature. The icing insulates the cookies. That may be about the longest you’d want to keep them, but they might be ok that way.
This is so much better tasting than royal icing!
I’m glad you enjoy it!
Does the frosting get sticky and wet when the cookies are sealed in a Tupperware covered container?
Not in my experience. It shouldn’t.
I have been making cookies for years and every holiday. But the last couple of years after the cookies dry little white spots appear, my recipe is the same as yours. What could be wrong?
Huh. Interesting. I haven’t had that happen. Could they be tiny little air bubbles? It almost sounds like it’s crystallizing somehow. Do you use any corn syrup or do you leave that out?
I use a similar recipe using all of the same ingredients. It’s my understanding that the icing mottles when it’s too humid🤷♀️mine is called cookie glaze.
Hmm. I haven’t experienced that, but it’s possible. I would think the corn syrup would help.
What can you do to bake the cookie Without them getting soft and breaking to put them in a dish
That’s tough, because softer cookies are more likely to break. But if they are a little thicker, they are less likely to break and certainly dry, firm icing helps too.
Easiest and most delicious cookies. So many helpful hints. This is a keeper
So glad you enjoyed them!
This sounds great. Can you marble two colors before it dries?
Yes, definitely.
Can I put an edible image on top? Does it need to harden first?
I haven’t ever worked with edible images, so I’m not sure.
Hi, Can I use pure cane syrup for the corn syrup? I don’t use it. Now the one I have is dark. Can I use dark or find a light colored one? Thanks
I haven’t tried can syrup, but you could. Seems like it should be ok. I’d go with a light syrup, unless you’re coloring your icing a dark color.
