Both.
Frosting is what you put on a cake. It doesn't dry out and retains the same consistency with age.
Icing is what you put on a cookie. It dries and creates almost a glaze.
This is correct... because you can't separate cake and frosting. It's like Penn and Teller, Romeo and Juliet, peanut butter and jelly... one isn't the same without the other. The frosting brings out the best parts of the cake and vice versa. They should never be parted or pit against one another for the sake of sport, Samantha, and frankly I am saddened you would do such a thing.
Signature by rubah. I think.
Noo! I'm so shocked by the results of this!! Don't get me wrong, ideally I would have both. But icing/frosting is amazing!! I could probably eat a whole bowl of just icing. Buttercream-especially chocolate- is just the best thing ever! Mmm!!!
