How long can you freeze cake layers for?
I was thinking of making a red velvet cake for DH for Valentine's Day. I want it to be a surprise so I thought I would make the cake layers one day, freeze them, and then on Vday frost it while he is at work. I also wanted to freeze the layers because I recently saw on ATK that it makes frosting easier if you frost the cake while the layers are still frozen.
How far in advance can I make my layers?
