STEP 8/10

Use an adjustable sponge cake slicer to level the top of each cake by removing a very thin layer.
Using the cake slicer, cut each cake in half.
Place the cake board or drum in the centre of the cake turntable.
Add a small amount of chocolate buttercream to the board to help the cake stick to the board.
Place the first chocolate sponge on top of the cake board, ensure it is central.
Top with a thin layer of chocolate buttercream.
Use an angled spatula to level the surface.
Place the second chocolate sponge on top.
Top with a thin layer of chocolate buttercream.
Use an angled spatula to level the surface.
Repeat this layering process on top with the coffee cake layers and coffee buttercream.
Then repeat this process with the white chocolate layers and white chocolate buttercream.

STEP 9/10

Once the cake is assembled use the remaining buttercream to create the ombre effect:
Transfer the remaining buttercream into three separate piping bags.
Start at the bottom of the cake with the chocolate buttercream.
Pipe two rings of chocolate buttercream around the outside of the chocolate cake layer.
Then pipe two rings of coffee buttercream around the outside of the coffee cake layer.
Repeat this process with the white chocolate buttercream, then continue up on top of the cake with the white buttercream.
Dip an angled spatula into a jug of hot water, remove the excess.
Hold the spatula flat against the side of the cake so it touches the buttercream.
Use the spatula to scrape round the side of the cake, turning the turntable as you work.
Remove the excess buttercream from the spatula, save it for later – you can re-use for piping decoration if you are careful.
Clean the angled spatula in the hot water.
Repeat this scraping method until you have a smooth straight surface.
Clean the angled spatula again.
Scrape across the top of the cake to create a smooth, flat top.
Remove any excess buttercream from the spatula and repeat until smooth and flat.
Transfer the cake to the fridge for 30 minutes – 1 hour until the buttercream is set and firm.
Transfer any remaining buttercream into piping bags fitted with your choice of decorative tip (plain tip, star or open star) and set aside.

STEP 10/10

To finish
Add the whipping cream into a clean heatproof bowl.
Microwave in 20 seconds intervals until steaming, be careful not to boil the cream.
Set aside and let cool slightly – if too hot, it will split when the chocolate is added.

 

Add the dark chocolate into the cream.
Stir occasionally until melted and smooth.
Transfer the chocolate ganache into a piping bag and set aside.

 

Retrieve the cake from the fridge.
Place on the cake turntable.
Use scissors to cut the piping bag open by approx. 5 mm.
Start piping the ganache along the top edge of the cake so that it drips down the side – test a small area first to check the consistency.
If it is too runny, allow the ganache to cool slightly and try again.
Create the drip effect around three quarters of the top of the cake, leaving the rest plain.
Place the cake in the fridge for 30 minutes to set the ganache.

 

Remove the cake from the fridge
Pipe the remaining buttercream on top of the cake, alternating between flavours.
Finish with your choice of chocolate decorations.
