These were tasty, I enjoyed the chewy butterscotch and chocolate. I have to agree that I liked them just as much without any chocolate at all. I think if I were to do it again, I'd get some orange-infused bittersweet chocolate for them - my 66% bittersweet/33% milk choc. was too sweet IMO -- I liked the Mohn bars better.
Panning these up required every flat cooking surface I owned. Fortunately, it was really cold and windy outside, so I could put an (empty) fresh-out-of-the-oven sheet pan on the back porch, and it was cold within 3-4 minutes.
I ended up adding an extra half cup of flour to get the batter out of the 'runny' stage
Don't put them in a sealed container for the wife to take to school, or they end up adhering to one another...
