I wanted a moist recipe for a tray bake for my son to take to school. I doubled the quantity and cooked for 70 minutes. After 55 minutes I dropped some packet marshmallows around the edge to stop burning. It was delicious, and fed two classes with some to spare! Thank you for the recipe. I'm going to use it again as part of a chocolate cherry flavour wedding cake today. - 15 Sep 2016
