Designer Protein made a couple (not sure if they still do) that weren't bad taste-wise.
One was called Detour Bar and I forget the other, but they had peanuts and caramel, etc.
Pure Protein made a S'mores bar that was pretty tasty.
I don't remember the label content of any of these, nor do I know if they're even still made, but most of the halfway decent-tasting bars are loaded with sugar and I haven't bought any bars in years.
