For icing, in large bowl beat 1/4 cup vegan buttery spread, shortening, 1-1/2 teaspoons zest and 1-1/2 tablespoons juice with electric mixer at medium speed until light and fluffy. Add confectioners’ sugar, 1 cup at a time, beating well after each addition. If icing appears dry, gradually add 2 tablespoons milk; beat at medium speed until light and fluffy. Tint icing with rose icing color, if desired.
