Melt the butter and chocolate in a saucepan over a bain-marie. Remove from the heat and add the cocoa powder. Allow to cool.
Whisk the egg yolks with 200g of caster sugar until light and fluffy.
Whisk the egg whites with 15g caster sugar to a very soft meringue, taking care not to whisk it too dry.
Fold the egg yolk mixture into the cooled chocolate mixture until marbled.
Fold the soft meringue into this mixture, in two batches, taking care not to over mix.
Weigh 660g of batter into each tin.
Bake at 160°C in a fan assisted oven for 45 minutes, until a skewer inserted into the center of thecake comes out almost dry.
Let the cakes cool completely before spreading each cake evenly with 350g of the left-over batter.
Bake for a further 10 minutes.
Once out of the oven, allow the cakes to cool. When the cake has cooled, dust with cocoa powder and icing sugar.
