This sugar cookie frosting recipe creates a smooth, pipeable frosting that hardens perfectly for crisp edges and clean lines, ideal for decorating cookies with confidence.
Use meringue powder for best hardening results; substitute with pasteurized egg whites cautiously. Let frosting dry at room temperature for several hours or overnight for a firm finish. Use gel food coloring to avoid thinning the frosting. Store unused frosting covered tightly or refrigerated up to one week, stirring before use.
