Preheat oven to 160°C (320ºF). Place the chocolate and butter in a small saucepan over low heat and stir until melted and smooth. Place the sugar and eggs in a bowl and stir to combine. Add the chocolate mixture and stir to combine. Add the cocoa, flour and baking powder and stir to combine. Fold through the extra dark chocolate.

Pour the mixture into a lightly greased 22cm-square cake tin lined with non-stick baking paper. Bake for 50 minutes or until cooked when tested with a skewer.
