- 6 cups powdered sugar
- ¼ cup light corn syrup
- ½ teaspoon pure vanilla extract
- Pinch of salt
- 4 to 6 tablespoons milk
- Sprinkles, for cookie decorating
Whisk the powdered sugar, corn syrup, vanilla and salt to form a smooth icing. Add 4 tablespoons milk to thin out the icing, gradually adding more milk as needed. For piping, the icing should resemble the consistency of toothpaste. Transfer to a piping bag.
