Hey-o! The Sweetest Season Cookie Exchange week rolls on… and I’m sharing my favorite icing recipe.
In fact, it’s kind of a shock that I haven’t shared this with y’all before, as it’s something that is integral for so many different cookie recipes. (I’m looking at you, All-Butter Tea Cake Cookies, Greek Yogurt Cut Out Sugar Cookies, Pumpkin Spice Sugar Cookies and even these Sweet Potato Sugar Cookies, if you’d rather not have the marshmallow frosting.)

- Large glass bowl
- Sifter or a Fine Mesh Strainer to ensure there are no lumps in the sugar
- Liquid measuring cup
- Measuring spoons
- Ramekins to separate the icing for coloring
- Gel food coloring (I like this better than the drop kind because it’s a little less messy)
- Offset spatula or butter knives
- Wire cooling rack
- Parchment paper to cover the counter beneath the wire cooling rack so cookies can drip onto this instead of your countertop
How to make Frosting for Sugar Cookies
This frosting is super easy to make. In fact, you only need a few ingredients that you probably already have on hand.
Measure the dry ingredients
First and foremost, measure out the powdered sugar, and use a sifter to ensure there are no lumps in the sugar.
Season with salt, and whisk.
Pro tip: We add a pinch of salt to this recipe because it will make the icing not sickeningly sweet. Just a little bit of salt helps balance out sweet treats. 🙂
Measure the wet ingredients
In another bowl, combine vanilla extract and milk. Whisk ‘em together.
Mix all ingredients for the icing, then make it colorful
Pour them into the powdered sugar mixture, and whisk until combined.
Next, you’ll pour in the lemon juice, and whisk until smooth.
Yes, I know we’re doing lots of whisking. That’s how we roll with icing, y’all.
After that, you can divide the icing into various bowls and color them the colors of your dreams. Personally, I like gel food coloring to color this icing, but you can use the regular dropper kind, too, if that’s what you have on hand.
Decorate your cookies
Spread a thin layer on top of your favorite sugar cookie recipe, add sprinkles or additional stripes of color at your leisure.
Let the icing dry for 4-6 hours on top of the cookies at room temperature before storing in an airtight container.
Frequently Asked Questions
What kind of icing do you use to decorate sugar cookies?
Personally, I like a plain Jane frosting like this easy sugar cookie icing. It calls for minimal ingredients and adds some sweetness to a run-of-the-mill sugar cookie.
How long does this icing last?
Stored in the fridge, it’ll last for more than a week. But do you really want it to last that long? Noooooo.
Does this icing recipe harden?
Yes, but it takes a little time. Prepare for the icing to sit on the cookies for 4-6 hours before you’re able to transport them. Personally, I like to let mine sit overnight.
To make the hardening process faster, let the cookies dry on a wire cooling rack so that no icing pools around the edges. You can also pop them in the refrigerator uncovered for a little while to make the process speed up.
I see this icing recipe calls for milk. I don’t drink milk. Is there a substitute?
You can simply use non-dairy milk or you can use water.
My favorite non-dairy milks to use in this recipe are unsweetened cashew milk or unsweetened almond milk, which you would find in the refrigerated section of your grocery.
The only non-dairy milk I would not use for this recipe is coconut cream (from a can), as it would make the frosting entirely too thick.
How can I store the extra icing if I don’t have FIVE DOZEN cookies to ice?
You have two options:
- Half the recipe before making it so that you don’t have an excess amount of icing.
- Pour the extra icing into an airtight container (or multiple, depending on if they are different colors.) Pop them in the freezer and freeze up for a few months easily.
Help! I have a ton of cookies. Can I double this recipe?
Absolutely! This recipe makes a ton of icing—and it’s a thinner icing, so it goes farther than a thicker cream cheese icing—but if you need more, you can certainly double or triple the recipe without issue.
Erin’s Easy Entertaining Tips
This easy cookie icing recipe is the one I turn to, no matter the time of year, whenever I’m hosting people for cookie decorating.
Why? This icing is incredibly simple to make and easy for all to use, assuming they can hold a butter knife.
Make your icing in advance. The beauty in this recipe is that the icing can be stored in the fridge for quite some time before you use it. Let it come back to room temperature before it’s time to ice the cookies, though, or it’s going to be a little thick.
Let the kids get their hands sticky. I’ll be honest and tell you that I hate when my hands and my kitchen are sticky. But my kids l-o-v-e- being able to participate in the making of this easy cookie icing recipe. Depending on their ages, they can measure, whisk and color the icing! Let them do it, and just be mentally prepared to do the clean up and the de-sticky-ing of your kitchen. 😉
Put it in icing bags for easy application. If you’re having a cookie decorating party and are hosting a ton of people and don’t want to worry about icing being strewn across most surfaces of your home, I GET THAT. Use piping bags without tips (meaning you cut a teeeeeeeeny tiny hole on the end) to make your life easier and to make your house potentially less messy.
