Used different ingredients:
I have made this today and I used Demerara sugar instead of dark brown sugar plus I added 1 tablespoon of set honey and a generous handful of roughly chopped walnuts to the mixture. I cooked it in my fan oven on 140c for 1hr 30mins.... It is truely delicious, so much so that I have just popped a 2nd one in to bake, i'm pretty sure cake no.1 will not last long!
