it looks piped to me, but im not a 'piper' so im sure some one else can give you better advice on it, but to me it looks as thought its sort of , melted into the cake to give it a smooth join
My question would be, why would you want to?
Sorry, but it doesn't look great to me.
Yes, it looks piped. But it also looks like royal icing to me but you wouldn't want royal on a cake like that. It can't be more liquidy of BC, otherwise it would slip off.
Unless its a royal iced/fondant cake and its supposed to have a 'melted' snow look over the sides?
what does the whole cake look like?
It has to be some sort of winter cake. Cause that has to be snow. It kind of looks to me like they just used a coupler (with no tip) and swirled it around.
I agree with the others that said it looks like royal icing, but you wouldn't want to ice your cake with that. Royal gets hard. Although, if it was a "winter cake" it might also be just whipped topping piped on also, to give it a snowy look. It looks like maybe they may have just cut a small hole in the corner of a ziploc baggie and piped on.
I did a similar look on one of my cakes. Just pipe it with royal icing. Layer it to get the desired effect.
Looks like they used a curved tip and then wiggled it as they piped.
Thanks for all your replies. I believe it is suppose to be the look of snow. I thought maybe it was very thin buttercream.
it actually looks like marshmallow frosting to me. I use it a lot, and it gives that wonderful shiny effect... it's called a 7 minute frosting. I add a cup of mini marshmallows at the end for the marshmallowy flavor.
