Hi! Does anyone have some pointers or tutorial to suggest to achieve a marbled effect that looks lile the one in this picture with buttercream? I know there's the watercolor technique, but with this, all the colors blend "horizontaly". Any way to have more movement without painting on the buttercream, I certainly do not have the talent to do that!

Never having done it I'd guess one would ice it white 1st, then put some dots of the colors on and using a cake spatula smooth it upward at an angle.  I can picture doing it in my mind  -- hope you can :)

You can use an airbrush....

although, that kinda looks like fondant!!

I know this is fondant, but I was wondering if something similar could be achieve with buttercream. Unfortunately, I do not own an airbrush. I'll do some testing I guess with kakeladi's suggestion and one tutorial I found online where you used a parchement paper on wich you've applied your buttercream. Almost like a buttercream transfert.

Oh, gotcha! Yeah  - that could probably work!

My thinking is the same as kakeladi's, but I have not tried it either.  It also entered my mind that a buttercream transfer, made into a collar might work.
