Can I use whipped cream for a filling of a cake covered in fondant? Also can I use whiped topping under the buttercream? My client really wants whipped topping, but my understanding is you can only use buttercream under fondant.

I often fill my cakes with whipped cream or mousse...
On my blog is a tutorial for my way

Happy caking!

Whipped topping under fondant will not work. The whipped topping breaks down the fondant and makes it a sticky gooey mess!

Yes, it will work

Maybe I misunderstood the OP's question. Of course whipped topping will work as a filling, I use it all the time. I thought she was asking if it could be used under the fondant. In that case no, it cannot.

I agree doramoreno, whipped cream directly under fondant is a no go.
Possibly I misunderstood the question...

Neither of you misunderstood
I askeds both questions. I was told you cannot use whipped topping under fondant rather than bbuttercream and I wasw also told you cannot do whipped cream filling with fresh strawberries under fondant so thats what i'm wondering. Do you have a recipe for the whipped filling and instructions on how to do it?

Sorry for the confusion! Yes you can use it as a filling, no matter if you are frosting with buttercream or using fondant. However I use a whipped TOPPING not cream with my fresh strawberries. It holds up much longer than real whipped cream. I use Pastry Pride non dairy whipped topping. I also frost all my cakes with it. In my area, no one asks for fondant and very rarely do I get a request for buttercream.
