I baked my cakes and froze them. Do they need to be completely defrosted before I fill them and ice them?
I am using a strawberry filling and buttercream.
It's best to get them well defrosted; maybe not completely -- so they are room temp but can start when they are still cold. Icing them while fzn (like right out of the fzr) can cause the icing to peal off sometime down the road
I've only ever done it once but what I did was pull it out of the freezer a day or so in advance and put it in the fridge to defrost. Once it defrosted in the fridge I then iced it.
