An easy, smooth royal icing recipe for sugar cookies that requires no corn syrup, using simple pantry ingredients and delivering a glossy, pipe-friendly finish.
Do not skip sifting powdered sugar to avoid lumps. Use meringue powder instead of raw egg whites for safety and consistency. Whip until stiff peaks form. Adjust water gradually to achieve desired consistency. Store leftover icing covered tightly and refrigerate up to 3 days. Let decorated cookies dry at room temperature overnight for best results.
