Blood Orange Cake

"Blood orange cake with olive oil - this cake sounded appealing: the olive oil in the mix and the blood orange zest, with chunks of orange baked in the mix. But the chunks made the cake impossibly soggy; the blood oranges lost their blush and turned plain orange colour for some reason; and the olive oil? Meh. I’ve made corrections to the recipe below so it’s a nice enough cake now. Not a patch on brownie though."
