I made this buttercream and it is really great and fluffy!!! It has a great taste to it. I have not iced my cake yet so I am not sure how it will smooth. It did start looking weird but as I let the mixer go it looked a lot better. I used the whisk attachment and it worked great. I will use the recipe again. My only concern is not cooking the eggs.
I iced my cake and it was great. It does not crust but will hold up when making drop flowers. I am not sure if it will hold when making roses.
