We've eaten on it for a couple days in a row and it was still good.

 

I don't see why you couldn't make the filling ahead. It is mostly pudding.

 

I think it's better at least overnight... it sets up a bit.

 

I made this recipe when my husband was out of town and it was just my daughter. I realized how yummy they were and went to my neighbors and told them to take one or two of them. They gladly accepted the treat, and I even got a couple of orders from it! One neighbor told me that they kept meaning to ask for a catalog but kept forgetting when she'd see me. This was a great way to remind my neighbors of my business and how yummy the eating can be when you book a show!
