Welcome to the Cake Decorators Q&A

Yes, this can be done. Once you’ve iced the cake, allow the fondant to crust over before adding the chocolate drips in the usual way. Hope this helps.

I want to airbrush the buttercreamed cake, will the airbrushed colours run when I put chocolate drips on it.

I’ve never done it so not sure. I would do a test on a small section of the cake or on a small dummy to see how it behaves. If you don’t have a dummy, try it on the side of a small cake pan. ?
