I have some cake that I froze then defrosted with the intention of using it for a birthday cake. I started working on the cake when the top layer began to fall apart because it was to moist and the buttercream was to heavy. I got frustrated and dumped it all in a bowl and decided that i would make cake balls with it for christmas gifts for my co-workers.
My question is: Can I re-freeze the cake and icing mixture and defrost when I am ready to assemble and decorate the cake balls.
I would. I think I would first form all of the cake balls then freeze them like that though. You would end up handling everything less and it would be less work when you dip the cake balls.
I don't see any issue with re-freezing cake.. especially when you are mixing it with buttercream or ganache
