I am making a cake for a friends birthday on Thursday.. I made the cake tonight. It is a sour cream french vanilla cake . I am filling it with a vanilla cream filling and then frosting with buttercream. I want to put MMF over this and then decorate it with MMF flowers and bows.. When should I put the MMF on the cake.. Right now the cake is wrapped and in the fridge.. I was thinking of filling and frosting tomorrow night but not sure when I should do the MMF. I read that its not a good idea to put MMF in the fridge but with the filling in the cake it will need to be refrigerated. I did refrigerate a small practice cake this week that was covered in MMF and it seems ok..but it didnt have a cream filling, only buttercream made with crisco and butter..Also I was planning on attaching the MMF flowers to the MMF fondant with buttercream frosting.. Is this strong enough to hold fairly large flowers on the sides of the cake?
Appreciate any suggestions you can send my way..

Should be ok to do tomorrow although I am not a fan of refrigerating this kind of covering. Hard to say about the flowers. Fondant flowers don't always hold up well when refrigerated, they do tend to slime. I tend to do them up on toothpicks so that they are easy to stick in the cake sides. I have never just attached large fondant flowers with buttercream to the sides of a cake, unless you mean at the bottom border. I don't refrigerate fondant flowers at all. I would likely attach them as close to delivery time as possible.
I would also bag the boxed cake if you are going to refrigerate it.

I agree you should be ok to cover tomarrow....as the flowers and decorations should be done right before and make sure that its room temp before adding so just in case the colors dont bleed.

Thanks Squirrelly I can count on your to know the answers to the most perplexing problems.
Thanks to you too lastingmoments..
I have a tiny practice cake in the fridge that has MMF on it with a MMF bow on top.. everything looks ok but then I havent cut into it yet.. It is wrapped in saran wrap so maybe thats why it hasnt started to wilt..LOL
I think I will wait till the last moment to add the flowers , just in case they soften and start to sag or fall off.
Thanks for your help..

Good luck! A lot depends on how thin the fondant flowers or decorations are, the thinner, the slimier usually, once refrigerated.
