I haven't made it before but am anxious to. I have a few questions though. Can this be piped like buttercream? Will it hold it's shape? Would it work for the ruffle cake piped with the 104 tip? If not I might go with SMBC again, but it's for our anniversary cake and I know my husband would love the whipped ganache.

Yes, whipped ganache will pipe like buttercream and will hold its shape. I haven't tried the ruffle with the 104 tip, but I'm sure it would be ok. Hopefully someone else can speak up with any experiences that they may have.

Thanks for the answer. I went with the whipped ganache and it pipes beautifully. I opted not to attempt the ruffle cake though. The whipped ganache is super intense and I think that would have been way too much frosting. My husband will be very happy tonight.
