This recipe creates a smooth, glossy frosting perfect for decorating sugar cookies, featuring corn syrup for extra shine and a stable consistency.
For best results, ensure your butter is truly at room temperature for a smooth, lump-free frosting. Sifting the powdered sugar is crucial to avoid a grainy texture. This frosting can be stored in an airtight container at room temperature for up to 3 days or in the refrigerator for up to 2 weeks; bring to room temperature and re-whip before using if refrigerated.
