I made this lovely, fluffy, creamy, beautiful, white buttercream. Lovely. But then...
I put it in the fridge - with the 9 cake layers (oh thankfully the H wasn't home this weekend...). And then!
I btrought it back to room temperature, and beat it a bit more. And then I was shocked. Just shocked by what I saw!
Here is a cake layer that I had crumb-coated the previous day. Same frosting. Next day. It's YELLOW!
So strange! Goods news -- i decided to be more patient, let it warm a bit more and beat it a bit more, and it was fine. Interesting, no??
