Beat together all ingredients in a large bowl with an electric mixer at medium speed until just combined, about 1 minute.

Increase speed to high and continue to beat until icing holds stiff peaks, about 3 minutes in a stand mixer or 10 with a handheld. If not using icing immediately, cover surface with a dampened paper towel, then cover bowl with plastic wrap.
                                         
                                    
                                
                             
                        
                    
                    Cooks’ note:  Icing can be made 1 day ahead and chilled, its surface covered with a dampened paper towel and bowl covered with plastic wrap.
