This is what I do when I make this pie : Let's say I need it on a Sunday. So Saturday morning I would prepare the cream cheese layer and put it in the fridge. I would then immediately start making the raspberry layer because it needs to refrigerate the same amount of time as the cream cheese layer in the pie. After the day, about 6-8 hours in the fridge, I would spread the raspberry layer on top of the cream cheese layer and go to bed! The pie will refrigerate overnight (with both layers) and it will be ready to use the next day when I need it.
