Go piccolo - Box-wrap tightly-freeze -thaw- unwrap. Don't deviate. No problems. Relax. Now you are done way ahead of time and can relax.

Thank you guys so much! You're all so great! Where else can you come and ask a question from people who know just what you're going through? I did box it up and I wrapped the whole thing in cling wrap too. I'm going to hope I don't have to make too many repairs. Does anyone know how long it takes to come back to room temp and dry out?

I just make my own MMF. It's just a big bag of mini marshmallows 2 TBS of water and a 2 lb bag of PS. I don't even sift the sugar. I throw the MM in the microwave for thirty second and stir, then thirty more and stir and then about 20 more. I dump the whole thing of PS in my KA with the dough hook and then pour in the MMs. it's soooo easy. It's best if you let it cool completely before working with it. Also, this cake was so big, in order to transfer it in one piece, I taped 2 mats together and then flipped it onto the cake and peeled it off. So, the cake actually showed the underside of the MMF, which I don't prefer. But, I think it came out okay, for an ingot cake ; )

If possible, I would take it from the freezer Monday afternoon to the fridge...Tuesday afternoon, remove from fridge to countertop 'til Wednesday morning. Change out boxes and send DH and cake on their way.

I agree with Picolo send hubby to the store or tell him this is gonna cost him BIG TIME.
Let's see it should be worth at least, a shopping trip to the mall for ohh, a new Michael Khors purse, then a new outfit, a mani-pedi and a massage you will need after you remake this cake.

Thanks for sharing. I use the same recipe and sometimes it comes out great and some times it doesn't, but I am still learning.

Win has obviously been in my house the few times I've let a frozen cake thaw. LOL

Crossing my fingers that this works for you, OP!

Last summer I froze fondant covered mini cakes in aluminum tins. When I took them out of the freezer I removed the covers and did not touch them until the condensation was gone. A/C helped to minimize the condensation. Worked out fine.

I don't know if it's been said but DO NOT make this cake again, seriously! It will not be appreciated at all. Your time is better spent!

I would do as a pp suggested and box it, wrap it and go from there. It'll be fine. Most cakes in stores, etc are days old. Plus, you have fondant on it which helps to keep cakes fresh so you could even just leave it out provided it's not warm in your home. I would box it to keep 'stuff' away from it.

BTW...it's an awesome cake, you did a great job! I'm pretty lucky that my hubby sells my stuff to his boss/friends...even if it is at a discount.

Well, I uncovered the cake this evening, after letting it sweat all day in its box in an air conditioned room. It looked perfect! Thank you all so much for your help! Now, we'll see tomorrow how it tastes...

Thanks again! ~Mindy
