I am making my first stacked cake for my daughter's birthday party and I'm trying to make sure I have enough time to get it done. I work full time so I have only a few hours after she goes to sleep to do everything. I was thinking of baking the cakes on Wednesday night, filling and frosting them on Thursday, chilling them overnight and covering them with fondant and decorating Friday night so I don't have to do anything the day of the party. I dont have the freezer space to freeze the undecorated cakes and I don't want the cake to be stale come the party. Is baking Wednesday night for Saturday too far ahead of time?

you'll be alright if you wrap each tier tightly and refrigerate them.
