Hi all,

So I'm making a cake for Saturday. Friday I'll be assembling the cake. It's a ganache covered cake (no fondant), with a perishable mousse filing. Which is why I'll have to refrigerate it.

Now my question is: Does ganache sweat as it thaws? I know buttercream and fondant do, but don't have much experience with ganache. I want to be able to refrigerate my fully decorated cake, which will also have gum paste/wafer paper flowers on top. Any tips on how to do that? Or if that even is a good idea?

I have never, ever refrigerated my cakes before this because I've always believed they taste better otherwise. But this mousse filling has been requested so I'll have to.

This is a series of firsts for me. So please any insight would be soo helpful.

Thank you xxx

The ganache will more than likely condensate at about the same rate as fondant or buttercream under the same circumstances.  I refrigerate all three without any problems.  To avoid condensation, put your cake in a box and seal it well with plastic wrap.  When ready for delivery, let it come to near room temperature before opening the box.  Any condensate should form on the box and not the cake.  That being said, I've refrigerated my ganache covered cakes without being covered and they were still fine.

Do not refrigerate gum paste and wafer paper.  Moisture of any kind is the enemy of both.  Wait until just prior to delivery to add the details.

Thank you so much Sandra!! You're always such great help! xoxo


One more question :

So what you're saying is I put the ganache covered cake in the fridge and add the details once I've taken it out for delivery. Is that right?

I'll be delivering the care and asking them not to put it in the refrigerator until served so it comes to room temp in that time. (roughly 2 hours)

Will the condensation play a part in making the details soggy. Or that should be ok? Silly question I know. But I don't want to take any chances. Thanks!

To be on the safe side, I would take the cake out of the refrigerator and let it set at room temperature for maybe 1/2 hour before applying the decorations.  Both gum paste and wafer paper are super susceptible to moisture.  A ganache cake is quite sturdy, so unless it is going to be in a really warm environment, there is no need to refrigerate it again before the party.
