Simple Ingredients
These simple pantry staple ingredients are all things I keep on hand, they don’t go bad (except milk) making this recipe super easy to whip up anytime.
- 3 cups of powdered sugar
- 4 tablespoons of milk
- 1 ½ tablespoons of light corn syrup
- ½ teaspoon of vanilla, peppermint, or orange extract.. Which ever flavor you prefer.
- A dash of salt.
- *Optional – Food coloring, if you want colors. (Place small amounts of icing into separate bowls to make multiple colors)
- Plain cooled sugar cookies for decorating!
Store icing in an airtight container. The icing will keep in the refrigerator for up to 2-3 weeks, or at room temperature for 4-5 days.

Consistency Tips
For a smooth, even spread, the icing should be slightly thicker than a thick syrup. If it’s too thin, it may run and pool on the cookies. If it’s too thick, it will be difficult to spread.
To thicken: Add more powdered sugar, a tablespoon at a time, and mix well until you reach the desired consistency.
To thin: Add a few drops of milk at a time, mixing well until you reach the desired consistency.
For Piping
For delicate piping, the icing should be thick enough to hold its shape but still flow smoothly. If it’s too thick, it will be difficult to pipe. If it’s too thin, the lines will be blurry and uneven.
To thicken: Add more powdered sugar, a teaspoon at a time, and mix well until you reach the desired consistency.
To thin: Add a drop of milk at a time, mixing well until you reach the desired consistency.
Remember to:
- Mix thoroughly: Ensure that the powdered sugar and milk are fully incorporated to prevent lumps.
- Start with a small amount: It’s easier to add more powdered sugar or milk than to try to take it away.
- Test the consistency: Pipe or spread a small amount of icing on a cookie to see if it’s the right consistency.
Sugar Cookie Icing & Royal Icing
These simple ingredients make a sugar cookie icing rather than true royal icing. Here’s the difference:
Sugar cookie icing:
- Thinner consistency, ideal for spreading and basic piping on sugar cookies.
- Sets to a soft texture that hardens slightly but remains somewhat flexible.
- Made with ingredients like milk, which prevents it from hardening completely like royal icing.
Royal icing:
- Thicker consistency, ideal for detailed piping and precise designs.
- Sets hard and dries to a rock-like finish.
- Traditionally made with powdered sugar, meringue powder, and water.
While this recipe can be used for piping, it might not hold super intricate details due to its softer consistency. But, it’s perfect for general piping and spreading and covering cookies smoothly!
If you want a harder icing for detailed piping, I recommend checking out a true royal icing recipe that includes meringue powder!
The best choice of icing depends on what you want. This recipe is great for creating beautiful sugar cookies with classic spread and basic piping, and royal icing is best to intricate designs and have that hard, crisp finish;)

Decorative Sugar Cookie Icing
Ingredients
- 3 cups powdered sugar
- 4 tablespoons milk
- 1 1/2 tablespoons light corn syrup
- 1/2 teaspoon vanilla peppermint, or orange extract
- Dash of salt
- *Optional food coloring Place small amounts of icing into separate bowls to make multiple colors
- Plain cooled sugar cookies for decorating
Instructions
- Add Powdered sugar, 3 tablespoons of milk, corn syrup, and extract of your choice in a medium-sized bowl and whisk together till well combined.
- If coloring the icing with different colors, divide it into bowls and color as desired at this point.
- Put icing in a piping bag with a piping tip.
- Decorate! If using sprinkles add them before the icing starts setting.
- Allow icing to completely harden for 3 hours. Share & Enjoy!
Notes
- Sifting the powdered sugar: This is crucial to remove any lumps and ensure a smooth, silky icing.
- Adding milk gradually: Start with less milk than the recipe calls for and gradually add more until you reach the desired consistency. You want the icing to be thick enough to hold its shape but thin enough to spread and pipe easily.
- Corn syrup vs. invert sugar: While corn syrup works in this recipe, using invert sugar (available online or at some baking stores) will prevent the icing from crystallizing and give it a more professional shine.
- Extracts: Choose an extract that complements the flavor of your cookies. Peppermint extract pairs well with chocolate cookies, vanilla is classic, and orange extract goes well with lemon or citrus-flavored cookies.
- Food coloring: Use gel food coloring for vibrant, concentrated colors. Avoid adding too much, as it can thin the icing.
- If you want a thinner consistency for spreading over large areas, add a little more milk until it flows easily but doesn't drip off the spoon.
- Use a spatula or offset knife to spread the icing evenly over the cookies.
- If you want a thicker consistency for piping designs, add less milk until the icing holds its shape and doesn't run.
- Transfer the icing to a piping bag fitted with a small tip ( Wilton #2 or #3). Practice piping on a piece of parchment paper before decorating your cookies.
- This icing will set to a soft texture that hardens slightly but remains somewhat flexible. If you prefer a harder icing, consider adding more powdered sugar until it reaches the desired consistency.
- The icing can be stored in an airtight container at room temperature for up to 24 hours. If it hardens, whisk in a few drops of milk to return it to its original consistency.
