This is a good substitute for 'real' meringue buttercream frosting. I am a semi-professional baker and use this on occasion to make a quick filling for cakes at home. I don't always have the time to make a true meringue buttercream. Liquors, fruits, etc. can easily be added to achieve a special filling. My favorites include Grand Marnier, Chambord or Bailey's Irish Cream. Yummmm!
