Can anyone give me some advice on airbrushing a stacked buttercream cake? Is it best to do the airbrushing once it is stacked or before stacking? I will be using different colors/design on each tier.
Never ever airbrush a stacked cake unless you are purposely wanting the color to be on both tiers. Like if you are starting off black on top and fading down to white at the bottom of the bottom tier. Don't underestimate overspray and gusts of air from an air conditioner that suddenly kicks on.
I have never airbrushed on buttercream but with when I have airbrushed fondant stacked cakes I airbrushed them when they were not stacked and then let them dry and then stacked them. because i did black, white, black.
You tend to get alot of overspray so i wouldnt trust myself to airbrush a stacked cake if i was using differant colors.
Yes, I was afraid of the overspray, but I also don't trust myself to do a perfect stack without mucking up the airbrushing-what to do!
Some one had posted earlier today, that shen she puts her dowel rods in she leaves them a couple inches out of the cake, then allows the next layer to push them al the way in. This might help to keep from smudging your tiers. Good luck HTH
