I’m trying to do much the same thing, only I need to convert the White Chocolate Whisper Cake to a full sheet version, and I can’t find that type of conversion anywhere in my edition of TCB (1988, a first edition that won’t ever be worth anything to anyone but me, as it’s full of my notes.). Can someone help me? My main problem is time. I need to make it for a photo show opening reception on the afternoon of the 8th March, but, because of when my payday hits, I can’t get all of the ingredients I need until the 6th March. Therefore, I’d like to know all of my conversions by the middle of the week, if at all possible. Any saviours out there? Thanks in advance!!
