Melt the 5 oz (150g) of chocolate over bain marie. Chop the 2 oz (60g) of dark chocolate and set aside.
Place the eggs and sugar in a heatproof bowl. Place over a saucepan of simmering water and, using a hand-held electric mixer, beat for 6–8 minutes or until thick and pale. Remove from the heat and allow to cool slightly.
Mix in the mascarpone into the egg mixture. Fold the melted chocolate until well combined.
Whisk the cream until stiff peaks form. Add the cocoa powder and gently fold through the egg mixture until well combined.
Fold in the chopped chocolate. Cover and freeze for at least 4 hours or overnight.
