Preparation Time: 4 hours including cooling and cooking
For the cake:
- 335g plain flour
- 525g soft brown sugar
- 125g cocoa Powder
- 2 tsp baking Powder
- 2 tsp bicarbonate of soda
- 3 eggs
- 185ml coconut oil or vegetable oil
- 2 tsp vanilla Extract
- 375ml whole milk
- 2 tsp instant espresso coffee
- 375ml boiling water
For the milk chocolate ganache covering/filling:
- 600g milk chocolate
- 300ml double cream
For the marble shards:
- 150g dark chocolate
- 75g white chocolate
- 100g white chocolate chunks
For the drip topping:
- 150g dark chocolate
- To make the marble shards, line a 30 x 20cm baking tray with greaseproof paper. Break 150g of dark chocolate in a heatproof bowl. Place the bowl over a pan of barely simmering water and stir until melted. Melt 75g of white chocolate as above.
- Pour the melted dark chocolate into the lined baking tray. Spread the chocolate to the edges of the tray with a pallet knife and tap the tray on your surface to smooth.
- Spoon blobs of the white chocolate randomly over the dark chocolate and using a cocktail stick or wooden skewer create a marble effect by swirling the two chocolates in a figure of eight pattern repeatedly.
- Sprinkle the white chocolate chunks over the melted chocolate.
- Place the chocolate in the fridge and allow to chill for 3 hours or until completely set.
- Once set break the chocolate into shards by hand.
- Whilst the marble shards are setting make the ganache. Put the cream in a saucepan and heat gently over a low heat, until the cream is bubbling. Keep stirring whilst the cream is heating.
- Once boiling, remove the cream from the heat and break the milk chocolate into squares.
- Add the milk chocolate to the cream and stir until melted.
- Chill in the fridge for 2 hours until set and thickened.
- Meanwhile make the sponge cake, preheat the oven to 180c 170C (150C fan oven, 325F, gas 3) 170C (150C fan oven, 325F, gas 3)(160c fan oven, 350F, gas 4). Grease and line 4 x 7inch round cake tins. Do not use loose bottomed tins as the cake batter is very liquid.
- Put all the ingredients for the cake except the hot water into a bowl and fold carefully until all the ingredients is mixed.
- Add the boiling water and with a hand whisk, mix until you have a smooth consistency.
- The cake batter will have a very liquid consistency. Pour the mixture into a jug and divide the mixture evenly between the cake tins
- Bake for 30 minutes until cooked and a cocktail stick or skewer comes out clean. Leave to cool.
- Once the cake is cooled, use a small amount of ganache to stick the base tier of the cake to the cake board.
- Spread the ganache on each layer of cake using a pallet knife and stack the cake together. Then spread a thin amount of ganache on the outside of your cake, starting from the base and working up the cake.
- Chill for around 30 minutes in the fridge until set.
- Add another layer of ganache around the whole cake and once covered, use a hot palette knife (you can dip this in a cup of boiling water) to get a smooth finish.
- To make the chocolate drip, break 150g of dark chocolate in a heatproof bowl. Place the bowl over a pan of barely simmering water and stir until melted.
- Leave to cool slightly for around 5 minutes
- Pour the melted chocolate onto the top of your cake and using a palette knife, spread over the top of the cake and push to the edges of the cake so that it starts to drip over the edge.
- Whilst the chocolate drips are still setting, insert your shards, by making some incisions in the top of the cake (around 1inch depth) using a small sharp knife to help the shards stay upright.
- If your ganache is too stiff to spread, warm it slightly in the microwave for about 20 seconds, then stir.
- Fresh berries add a great finishing touch to the cake, try placing onto of the cake when adding the chocolate shards.
- Try spraying the berries and white chocolate chunks with gold shimmer spray for a festive finishing touch.
