Nigel Slater's Chocolate Muscovado Banana Cake

It really is worth making yet another banana bread. The combination of the brown sugar and the dark chocolate ( I chopped up some pastilles of very dark 85% cacao) and banana is just wonderful. And what a pleasure to line the pan with parchment--no greasing, easy release and easy clean-up. I mixed it all in my stand mixer. It took a little longer than the suggested 50 minutes, but it's easy to tell when it's done as the top browns up nicely and the bread becomes firm. A very big hit among all tasters.
