Sorry the whole pic uploaded. I'm just looking at the pink smash cake. Can anyone help?? I love the looks of this but have never done the ruffles before! Please and thank you for your help!!! :)
definitely looks like fondant to me.
Here is one done in butter cream which shows you how to move your wrist when piping. At least this is another option for you if you prefer butter cream like I do. The below looks like she filled the piping bag up too much but never the less will show you the method of how. She is using the rose tip for doing this. If you want a bigger ruffle you can go up to the rose petal tip 125.
Here is another one done a different way.
If you prefer fondant I am sure you will be able to find many videos on youtube pertaining to fondant also.
Good Luck/ You can do it!!!
I made a video piping buttercream ruffles with the giant rose tip #127 D.
(I'd use a 124-127 for multiple layers of ruffles.)
That's definitely buttercream...Just use a big petal tip and wiggle it in a wavy shape while piping. Start a the bottom and work your way up.
AI've seen that exact cake on Facebook and its done with fondant.
