Easy Icing for Sugar Cookies
One of my favorite things to do around the holidays is decorate Christmas sugar cookies. I love to use Christmas-shaped cookie cutters, festive sprinkles and different types of cookie icing. So fun!
It’s simple, hardens quickly, has a glossy look and tastes delicious. It’s basically an easier version of royal icing without the added egg whites or meringue powder. Plus it works for all types of cookies too, such as butter cookies, shortbread cookies and gingerbread man cookies.
Sometimes frosting your own cookies with homemade cookie icing can be intimidating, but trust me, this recipe couldn’t be any easier! It’s perfect to make for a holiday cookie exchange and will leave your friends and family raving over how cute your cookies turned out!

4 Simple Ingredients
This recipe requires only 4 simple ingredients. These ingredients are staples for me around the holidays, so I already had everything I needed to get started.
Find the full printable recipe with specific measurements below.
- Powdered sugar: This is how the icing gets it’s sweet flavor. I don’t usually sift my powdered sugar, but you can if yours is super lumpy.
- Light corn syrup: This gives it a nice gloss and keeps the icing from losing it’s shine after it dries.
- Milk: You don’t need a lot…just enough for it to thin out the consistency a little.
- Vanilla extract: I love adding in vanilla for a boost of extra flavor. You could always switch up the flavoring and use almond or lemon extract.
How to Make Sugar Cookie Icing
Before getting started, use my favorite sugar cookie recipe to bake your cookies. Then let them cool completely before adding the icing.
- Combine. Stir together ingredients in a bowl until smooth and glossy.
- Color. If desired, tint with gel food coloring of choice.
- Frost. Spread on cookies using a knife, spoon or frosting bag or bottle.
PIPING TIP: If you are piping around the edges of your cookies, the icing should be thick (like toothpaste). Then when filling the center, add 1/2 teaspoon more milk at a time to reach the right consistency.
- Consistency. For the outer edge, the consistency should be thicker, like toothpaste. The center should be the consistency of honey.
- Icing method. You can dip the cookies into the icing or use a frosting bag or bottle. You could also use a knife or spoon. Whichever method you prefer.
- Extra decorations. If adding sprinkles, make sure to add them immediately after you frost your cookies. The sugar cookie icing dries quickly!
- Keep them shiny. It helps to dry the cookies in front of a heater fan to keep the icing shiny.
- Freezing. The icing sets up really nicely once dried and you can easily stack or freeze them.
The main ingredients are powdered sugar, milk and corn syrup. You can also add vanilla or other flavorings.
Frosting such as a classic buttercream is typically made with the addition of butter to make it thick and creamy with a richer taste.
This cookie icing does not contain butter and has a drippier consistency from the corn syrup and milk, which makes it ideal for decorating sugar cookies.
Royal icing is a popular choice, but I love this cookie icing because you don’t need meringue powder. It’s much easier to use. If I want a soft frosting and don’t need to stack the cookies, I’ll go for a cream cheese frosting.
It usually takes about 30 minutes to an hour for this sugar cookie icing to set completely.
You can speed up the process by placing the cookies in front of a heater fan to dry. This will help keep the icing extra shiny too.
How to Store Cookies with Icing
The best thing about using cookie icing that hardens is that you can easily stack and store your cookies. Once it dries completely (usually takes around 30 to 60 minutes), add a piece of parchment in between each cookie and then store in a covered container for up to 3 days. The cookies will also stay fresh in the freezer for up to 3 months.
Make Ahead Instructions
You can easily make this icing ahead of time to frost your cookies later. Simply prepare as directed, then store in the fridge in an airtight container with no air leaking in. I recommend filling the container completely, sealing with plastic wrap and then the lid.
Let it come to room temperature before using (about 30 minutes). You may also need to add a little more milk and corn syrup if it has thickened too much.
