Just wondering how long prior to delivery I can put a chocolate image on buttercream.

Basic worry is: will the chocolate melt with the moisture of the buttercreme.

Hope this makes sense. New technique and very curious.

Thanks for your help.

In my experience with chocolate transfers, they stay very firm...and I have placed them on the cake the day before serving. (Room is air conditioned, or else not warmer than 72 degrees or so).

When I did this technique recently, I put the chocolate image on the night before I delivered the cake. They didn't eat the cake until about 24 hours after I put the image on and there were no problems. The cake was in A/C the whole time, but not refrigerated. Good luck!

I use them all of the time and have no problem with them melting. My only advice is to put it on BEFORE the icing firms up otherwise it won't stick and you'll definitely have to put a glob of icing behind it.
