Preheat oven to 180°C/350°F/gas mark 4. Grease an 8” baking or lasagne dish.
Blend all the ingredients in a mixer until it forms a smooth batter. Pour into the prepared dish and bake until golden brown and just set (approx 50 minutes). Check by gently inserting a knife blade or skewer and if clean on withdrawing, this indicates the pudding is cooked.
Cool slightly and serve.
