A New Years Eve show-stopper of a cake!
This is luxuriously rich and chocolatey yet is surprisingly simple and quick to make (apart from the chilling time).
You will need a 25 cm springform cake tin, with the base and sides lined with non stick baking paper
Oven 180 degC, 160 deg fan
For the cake:
25g cocoa mixed into a paste with 3 tablespoons boiling water
add to this:
2 large eggs
100g caster sugar
100g self raising flour
1 level teaspoon baking powder
100g soft butter
Whisk using an electric mixer for 1 minute. Spread the mixture into the lined tin and bake for 20 minutes. It will have shrunk away from the sides of the tin a little.
Sit the tin on a wire rack to cool, don't remove the cake from the tin! Sprinkle over 2 tablespoons of rum or brandy while the cake is still warm and let it soak in.
While your cake is cooling melt 300g of dark chocolate (I do this in the microwave in 1 minute bursts, reducing to 10 second bursts) allow to cool a little.
Whip 450 ml cream to a softly peaking stage, then gently fold through the melted chocolate, do this thoroughly until there are no streaks. Spoon the chocolate mousse on top of the cake, smoothing the surface carefully to get a neat finish. Chill for at least 6 hours or overnight in the fridge to firm.
Release the springform clip of the tin and remove the ring. The cake on the pic is straight after the tin was released and sometimes the sides may look a little rough, you can use a hot, wet palette knife and run it around the outer edge in one quick movement to neaten it, but you have to be confident to do this in one action and it helps to put the cake on a turntable.
Dust the top of the mousse with cocoa powder, pile on some berries of your choice. Give it a final flourish of icing sugar over the top of the berries.
Serves at least 12 people, small slices are best. Enjoy!
