Homemade Sugar Cookie Icing
I absolutely love making sugar cookies. Sure, it can be a process and require some clean up, but it’s all about making memories and eating a little sugar along the way. We always decorated cookies at Christmas time when we were kids. I loved to help my mom make the cookies and then we would decorate them as a family.
My mom always had two types of frosting, buttercream and icing. While I am partial to buttercream myself, we often used the icing recipe when we were kids.
The icing is quick & easy, and it’s thin enough that we used to paint it on our cookies with actual paint brushes, how fun is that? It’s perfect for kids because they can do it themselves, or with very little help.
You can use this icing recipe in three different ways: to dip your cookies into, pour over your cookies, or use to make marbled iced sugar cookies; this is my favorite look!
Why you’ll love this icing:
- It only requires 4 ingredients
- You can make it in 5 minutes with no special tools
- It dries completely, so they’re easy to store and share
- It easy to color this icing
- You can easily adjust the consistency
- You can create a gorgeous marble effect
- It’s the perfect icing for kids
Recipe ingredients:
- Powdered sugar: It’s important to sift this through a fine mesh colander to break up any lumps
- Corn syrup: Gives a light sheen to these but also helps to hold the icing together
- Milk: Any type of milk will work!
- Flavored extract: Vanilla, Peppermint, Almond or lemon
How to Make Sugar Cookie Icing
- Sift the powder sugar in order to avoid lumps in your icing as it dries
- Combine the powdered sugar with the corn syrup and milk and whisk until they’re well combined.
- If desired, add ¼ – ½ teaspoon of extract such as vanilla, almond, peppermint or lemon
What’s the correct consistency for icing?
The consistency should be thinner than corn syrup but thicker than maple syrup. When running off the spoon, it should hold together and slowly drip. A thicker consistency (similar to corn syrup) will work fine, it will just take longer to dry. A thinner consistency is easier for kids to use, especially if they are spreading or painting it on. The thinner the icing, the more transparent it will be once it’s dried.
How to adjust the consistency: To make the icing thinner, add additional milk 1 teaspoon at a time. You want it to be drippy but not runny. If you think your frosting is too thin, add more powdered sugar ¼ cup at a time.
Can You Color Sugar Cookie Icing?
Yes! You can easily add color to this icing. I recommend using Gel colors such as Amerigel (affiliate) or Wilton’s Color Right Color System (affiliate). Amerigel offers lots of individual colors, so you can get super specific, whereas Wilton’s is 8 basic colors that you can mix together to create over 50 different shades. You can purchase them at craft stores, cake supply stores or online.
Using Colored Sugar Cookie Icing for Marbling
If you add a couple different drops of color to your bowl of sugar cookie icing, you can use a technique called “marbling” to make pretty cookies with hardly any effort.
The key here is not to mix your icing too much, otherwise the colors you’ve added will blend together and you won’t get the swirly marbling effect when you dip your cookies in the colored icing.
Here’s how to do it:
- Prepare a batch of icing and divide into bowls for each color. Line a cookie sheet with parchment paper or a silicone baking mat (affiliate).
- Use only very small amounts of the gel color and gently swirl with a toothpick. I recommend using 1-2 colors per bowl for the best effect.
- Save some of the white icing to the side. This gives you the ability to add some white back in to your swirl. After you dip a few cookies, your icing will start to lose some of the white on the surface
- Wear some disposable gloves if you have them. These can be a little messy and the gel colors will easily stain (fingers, clothes, counter tops) unless you wash it off right away.
- Let the icing drip. When dipping your cookies, allow some of the icing to drip back into your bowl before you flip it over, otherwise it will run all over the sides of the cookie.
- Tilt the cookies: You can change the direction of marble by tilting your cookie as you pull it up from the icing
How to Store Decorated Sugar Cookies
One question I get a lot is: How do I store my sugar cookies once I’ve decorated them with icing?
The answer is super simple because the icing does dry completely, meaning you’ll be able to stack these cookies once they are fully dry. It can take anywhere from a couple hours to overnight depending on how thick your icing is. You can cover the cookie sheet with foil, but don’t let it touch the cookies. Let these dry completely on a cookie sheet before stacking and then store in an airtight container.
