I'm feeling stumped. Going to a friends on Saturday night for dinner and I'm bringing dessert. Originally I was going to make gingerbread but hubby doesn't want that.

I've brought the CI peach and blueberry gallette with homemade ice cream to these friends before, and an assorted tray of biscotti and toffee.
4 adults, 4 kids but all the kids have adult tastes pretty much, just nothing boozy. I don't know what the hostess is serving but she's a great cook and hostess so we are typically not all too hungy by dessert anyway.
I have to make it Friday night or Saturday morning/late afternoon. But won't have time before then.
I just saw the peanut butter cupcakes on SE and they look good, but I'm not great with cupcakes normally. They sink, or puff up too much, or they are too dry.
Any suggestions?
