I used wholemeal spelt flour in this recipe and instead of chocolate, used 25g of fine cocoa powder powder with slightly more sugar and two pinches of salt. Was very easy to make, the cooking was perfect (cooked for 30 mins) and the brownies rose beautifully. I cut the cake into sixteen squares and ate two, warm, with cream! They were so delicious, with a chewy topping and perfectly light and tasty texture that I had to have another two squares. Just to die for!!
