Just a quick question and thanks in advance! I plan on using whipped ganache on a cake tonight which will be served after lunch tomorrow. I have fridge space at home, but does it need to be refrigerated until it is served?

Thanks for your help!

No it does not

How long could it stay out? Also I've never used it as icing before, can you do this or is it better as a filling?
Thank you!!

No it does not

I have used whipped ganache as frosting before and it was perfect.

I've always assumed that it needed to be refrigerated. With all of that heavy cream, how can it be safe? Just curious...

The recipe I use is Dede Wilson's and she suggests to refridgerate. Maybe it depends on the recipe.

I'd recommend refrigeration, there's a lot of cream in it. It can be out for several hours without problems, but...
