For icing, whip meringue powder, water and 1/4 cup sugar in large bowl with electric mixer on high speed for 5 minutes. Gradually add remaining sugar and continue whipping at high speed 5 minutes or until meringue is stiff and dry. Pipe a 1M swirl of meringue on each cupcake. Place back in muffin pans or on cookie sheet. Broil 30-45 seconds, or until meringue is lightly toasted.
