This Australian retro classic is cosy, fun and affordable! A chocolate sponge sits on top of a pool of chocolate custard. You simply make a thick batter, then pour over the custard ingredients... something magic happens in the oven, and the sauce sinks to the bottom! Serve immediately out of the oven to get that satisfying scoop of runny sauce underneath - sure to delight kids, it's a great family friendly dessert. Serve with vanilla ice cream.
