Either a couple days before, or to freeze.
We are holding a coffee morning type affair on Saturday so of course cakes are obligatory. Our target demographic is older so new dangled nonsense like cupcakes aren't a big hit, good old fashioned slices are definitely the preferred mode of serving.
I am working all week and won't get home till 5ish, Friday night will be mostly spent arranging the other elements of the event so baking time will be limited.
I have felt my opposite number in this venture has doubted my abilities in the fundraising department in the past bitch so the pressure is on to make sure I provide several wonderful cakes that don't taste like cardboard
