Oh my, the different layers of flavors in these blondies are simply outstanding. Browning the butter adds a nutty flavor to the blondies. They have a toffee-like flavor. The blackberries, though, steal the show. They are marinated in balsamic vinegar and add a lovely tartness that pairs well with the sweet blondie and whipped cream. If you can’t find pomegranate balsamic vinegar, substituting it with regular balsamic will work too.
