I baked, iced and froze a cake last week to help me save time for a cake due today. I had the cake on the cake board, wrapped in saran wrap, wrapped again in saran, then again in tin foil.

When I unwrapped the saran, a lot of the colour in my icing seemed to go with it. It was iced in blue buttercream. Now it has white splotches all through it. Kind of looks like the imprint of saran wrap on the cake, only it's not imprinted..the icing is still smooth, instead it's white and blue instead of all blue.

Any idea why my colour seemed to vanish?? Nothing on the saran wrap.. no icing or any lingering blue. Has this happened to anyone before? Can you not ice in colour then freeze??

I've lost some faith in freezing now

some colors are notorious for fading. blues, pinks, lavendars are all prone to fading. It may or may not have been caused by freezeing. The places where the wrap touched the cake were changed or protected, depending on which spots faded.
