Instructions
Preheat the oven to 170°C and line a 25cm cake tin with baking paper.
2. Sift the flour, cocoa powder, bicarbonate of soda and baking powder
together in a bowl.
3. Beat the butter and castor sugar together in a separate bowl. Add the eggs
one at a time. Add the vanilla extract, buttermilk and water.
4. Combine the wet and dry ingredients, and mix until smooth.
5. Pour the batter into the prepared cake tin and bake in the preheated oven,
30 minutes.
6. For the dark-chocolate mousse, place the water, sugar and glucose or
golden syrup in a pan and bring to a boil over medium-high heat. Remove
from heat, add the chocolate and stir until smooth. Beat the cream and fold
into the chocolate. Place the mousse mixture in a large bowl.
7. For the milk-chocolate mousse, repeat step 6, using the milk chocolate.
8. To construct the mousse, line twelve 6cm ring moulds with cling film. Cut the
chocolate cake with a 6cm round cutter and place in the bottom of each
mould. Top with a layer of dark chocolate mousse. Add a layer of milk
chocolate mousse, then refrigerate, 30 minutes.
9. While this is in the fridge, make the ganache. Warm the cream and coffee
bean over a double boiler (do not allow the water to touch the bottom of the
bowl). Remove the coffee bean and add the dark chocolate. Stir until
smooth and shiny.
10. Remove the mousse cakes from the fridge, top with the ganache and
refrigerate for a further 2 hours to set. Remove from fridge and serve
immediately, dusted with cocoa powder.
