One of my coworkers bakes coffee cake that is made with pistachio pudding every year when it's her turn to do dept meeting snacks. Sounds iffy at best, I know, but it's divine. I dream of that coffee cake all year.
Sadly, I don't have the recipe to pass along, as I've never asked her for it. If I made it, DH wouldn't like it and I'd end up devouring the whole thing within about 24 hours...
