I am planning on making these for a party Saturday but I have a lot to do and get ready and I want to have as much done ahead of time as possible. Does anyone know if these can be made up ahead of time and if so how far ahead. Can you do the whole thing filling and all or just have the puffs and filling made and put them in closer to serving time. I've never made them before and I'm going to have to make a couple batches, so any tips or words of wisdom would be welcome! TIA!!!
