I love vanilla pudding but mostly on top of warm bread pudding OR a mix of vanilla pudding and custard.
Other than the rare banana pudding, I don't recall it being served much when I was a kid. Nor have I made it as an adult. Nor have I made Jell-O.
You gotta wait a month. National Chocolate Pudding Day is June 26. It falls on a Monday this year. I could send you a reminder on the Friday before so you could whip up a big batch of it over the weekend. There's liable to be a run on the ingredients as everyone celebrates the day.
