Add in the corn syrup, vanilla extract, and milk or water. Stir vigorously until the mixture is smooth and well combined.

Common Mistakes to Avoid
Avoiding common mistakes will help ensure your sugar cookie icing turns out perfectly every time. Here are some pitfalls to watch for:
- Bold consistency issue: If your icing is too runny, it won’t harden properly. To fix this, gradually add more powdered sugar until you achieve a thick but pourable texture.
- Bold skipping the sifting step: Not sifting powdered sugar can lead to lumps in your icing. Always sift it before mixing to ensure a smooth finish.
- Bold neglecting color mixing: When adding food coloring, do so gradually. Too much at once can lead to dark colors that don’t match your vision. Start with a drop and mix thoroughly before adding more.
- Bold rushing the drying time: Icing needs time to set properly. Don’t store cookies until the icing has fully hardened; otherwise, they may smudge or stick together.
- Bold overcomplicating flavors: While you might want to add extra flavoring, too much can alter the icing’s consistency. Stick with vanilla extract for best results.
