I plan to take a pineapple upside down cake to dinner at a friends tomorrow. It seems like a way to make this a day ahead and keep it fresher, would be to use parchment in the bottom of the pan and leave it in the pan until just before departure, then flip it and peel off the parchment.
I'm sure someone else has tried this before. What were the results? Any other advice?
