I have been asked to make a whipped cream icing wedding cake. Two-tier, not huge. I cannot talk the bride out this choice. The cake will be refrigerated and it is a small, indoor reception. My problem is I have never piped whipped cream icing and am not familiar with its properties. Can I pipe in detail? Should I pipe using royal icing instead? Can I color as usual? Any help/suggestions will be greatly appreciated.

Depending on the type of whipped cream frosting you are using, sure you can pipe with it like BC frosting. So far I've only used Bettercreme. With this you have to be careful how you whip it, if it is over whipped it thickens up and look curdled, this can easily be fixed by adding more. However, there are some good forums on Bettercreme with how to prepare and decorate with it here on CC. There are others whipped cream frostings that can do the same thing. I've was able to smooth it, pipe roses and leaves, basic flowers. Search the internet for more references. HTH

Thank you so much for the help. I have heard of Bettercreme and may give it a try. Will this hold up better as well? I have to deliver the cake the day before the wedding therefore preparing it 2 days prior.
Say a prayer all goes well!

To frost and pipe with whipped cream for this far ahead is going to require the use of gelatin to stabilize. But that also makes the piping easier.

When i make fresh whipped cream. i use gelatine to stablize it and also piping gel. I can pipe flowers , etc. with this. hth

I use Pastry Pride which is about the same as Bettercream. I use that 100%, no one around here ever asks for fondant or even buttercream! If you look thru my gallery, you can see what can be done with a non dairy stabilized whipped cream topping.
