If royal icing feels fiddly, this shortcut delivers a very similar result without the fuss. Made with confectioners’ sugar, butter and milk, it creates a glossy, flavorful finish that sets semi-firm and works for dipping, flooding or spreading. It contains no corn syrup and comes together in minutes.
Is Cookie Icing the Same as Royal Icing?
This cookie icing isn’t true royal icing, which relies on egg whites or meringue powder. Instead, it uses confectioners’ sugar, butter and milk. The texture is comparable once it sets, and you can use it the same ways: dip cookies, pipe details or “flood” cookie tops. It won’t dry rock-hard like royal icing, but it firms up nicely—about 10 minutes at room temperature for a semi-firm finish.
3 Simple Ingredients
What makes this icing so reliable and easy:
- Confectioners’ (powdered) sugar: The base of the icing. Sift for a silky texture—do not substitute granulated sugar.
- Unsalted butter: Adds richness and helps the icing set. Use unsalted to control the sweetness.
- Whole milk: Gives a creamy consistency. Add gradually to reach the desired thickness for spreading or dipping.
Kelly’s Note: For extra flavor, stir in a splash of vanilla or almond extract. Add a little at a time so it doesn’t overpower the delicate cookie taste.
You can tint this icing with liquid or gel food coloring. Gel colors give brighter shades with fewer drops.
How To Make Sugar Cookie Icing
No special equipment required—just a bowl and a whisk. The steps are quick and forgiving.
- Sift the confectioners’ sugar into a bowl to remove lumps.
- Add the melted butter and whole milk and whisk until smooth.
- If the icing is too thick, add milk 1 teaspoon at a time until it reaches the right spreading or dipping consistency.
- If using food coloring, whisk it in until the shade is even.
How Do You Decorate Sugar Cookies Like a Pro?
Start with a sturdy cutout sugar cookie for best results—cookies should hold their shape and be completely cooled before decorating. Chilling baked cookies briefly can make application tidier. Follow these tips for professional-looking results:
- Make sure cookies are fully cool; warm cookies will soften the icing.
- Chill cookies in the fridge before decorating to make spreading or dipping cleaner.
Two easy ways to apply the icing:
- Dip cookies into the icing and tap off excess.
- Use a small spoon or an offset spatula to spread a thin, even layer.
Color and Customize
- Use squeeze bottles or piping bags with small tips for detailed work and borders. Squeeze bottles are beginner-friendly.
- Keep multiple bowls of colored icing and your sprinkles within reach for faster decorating.
- Cover bowls with plastic wrap or stir occasionally to prevent a thin skin from forming.
Sprinkle Like a Pro
- Add sprinkles immediately after icing—this icing firms up quickly, so waiting will prevent sprinkles from sticking.
Allow Time to Set
- The icing becomes semi-firm in about 10 minutes. For fully hardened icing suitable for stacking or shipping, allow up to 24 hours.
With these steps, you’ll have beautiful iced cookies that taste as good as they look.
Can I Make This Icing In Advance?
This icing is best when made and used the same day. It begins to set as it sits, but you can gently reheat it in the microwave in short bursts (5–10 seconds), stirring between intervals, to restore spreadability. Avoid making it too far ahead, or it may become overly firm and difficult to apply smoothly.
Can You Freeze Iced Sugar Cookies?
Yes—iced sugar cookies freeze well. Once the icing is fully set, arrange cookies in a single layer on parchment and freeze until firm. Transfer to an airtight container, separating layers with parchment or wax paper. Thaw at room temperature before serving; they’ll retain their appearance and flavor.

Sugar Cookie Icing Recipe
Ingredients
- 2 cups confectioners’ sugar
- 2 Tablespoons unsalted butter, melted
- 3 Tablespoons whole milk, plus more as needed
- Food coloring (optional)
Instructions
- Sift the confectioners’ sugar into a medium bowl.
- Add the whole milk and melted butter and whisk until smooth. If the icing is too thick, whisk in additional whole milk 1 teaspoon at a time until thinner. If desired, whisk in food coloring.
- Dip cookies into the icing or use a spoon to spread a thin layer on the tops. Let cookies sit at room temperature until the icing sets, about 10 minutes.
Kelly’s Notes
- This icing is best used right away. If it thickens while standing, gently warm in the microwave in 5–10 second bursts and stir until spreadable.
- Iced sugar cookies freeze well. Once icing is set, freeze in a single layer until firm, then store in an airtight container with parchment between layers. Thaw at room temperature before serving.
