Method:
1 Preheat oven to 180°C fan-forced. Grease a six hole, 1/3-cup capacity muffin pan.
2 Place flour and sugar in a bowl. Add milk, butter, egg, and chocolate, stir until just combined.
3 Divide mixture evenly among muffin holes. Bake for 15-20 minutes, or until a skewer inserted into the centre of muffin comes out clean.
4 Stand in pan for 5 minutes. Transfer to a wire rack. Dust with icing sugar and serve warm.
