Fondant petals on a buttercream cake?

It will be fine on a crusting buttercream. Let it set for a few hours. I would add wire to the petals back end and allow to dry, Will make it easier and cleaner look when inserting. GL

Thanks for your reply SeaCakes! I appreciate it :)

I use italian meringue buttercream for almost all my cakes and you should see some of the stuff I stick to the sides, LOL. Go for it, just make sure the petals are rolled thin so they will be lighter in weight. ;) Good luck!

I agree, I think it will work with Italian Buttercream

Absolutely! I’ve done a couple, one with buttercream & one with whipped cream (in the winter!) and the only part I needed to wire was the very center of the rose, the petals stuck quite nicely on their own :)
