For the ganache
150g (5oz) dark chocolate, at least
70% cocoa solids, chopped
125ml (4½fl oz) double cream

1 For the hazelnut truffles: Combine
the chocolate and butter in a heatproof
bowl. Warm together the cream, golden
syrup and vanilla extract in a saucepan
until just boiling. Carefully pour over the
chocolate and butter.
2 Let stand for 1 minute before stirring
until the mixture is smooth and even.
Cover the bowl and chill until the
mixture is set, about 1½ hours.
3 Using a melon baller, take scoops of
the truffle mixture and roll into rough
walnut-sized balls between oiled palms.
4 Roll them in a shallow dish of the
chopped hazelnuts, arranging them on a
baking tray. Chill for a further 30 minutes.
5 After chilling, melt the milk chocolate
in a heatproof bowl set over a half-filled
saucepan of simmering water, stirring
until smooth. Line a baking tray with
greaseproof paper.
6 Remove the truffles from the fridge
and add them, one by one, to the
melted chocolate, turning to coat with a
tablespoon. Arrange on the greaseproof
paper and chill until needed.
7 For the sponges: Preheat the oven
to 180°C/Gas Mark 4. Grease and line
three 15cm (6in) round cake tins with
greaseproof paper.
8 Combine all the ingredients for the
sponges in a large mixing bowl. Stir a
few times to roughly combine before
beating with an electric mixer until
smooth, about 3-4 minutes.
9 Divide the batter evenly between the
cake tins. Smooth the tops of the batter
with the back of a damp tablespoon
and tap on a flat surface to help
settle them.
10 Bake for about 20-30 minutes,
rotating halfway through, until risen
and springy to the touch; a cake tester
inserted should come out clean.
11 Remove to wire racks to cool. Once
cool, turn out from the tins and trim the
tops flat with a serrated knife, if needed.
12 For the buttercream: Melt the
chocolate in a heatproof bowl set
over a half-filled saucepan of
simmering water, stirring occasionally.
Remove from the heat.
13 Beat together the butter, icing
sugar, cocoa and vanilla with 2-3 tbsp
hot water in a large mixing bowl until
smooth and creamy. Fold through the
melted chocolate, then spoon one-
third of the buttercream into a piping
bag fitted with a star-shaped nozzle.
14 Stir the chopped cocoa nibs into the
remaining buttercream. Chill the piping
bag until ready to use.
15 Place one sponge cake on a cake
stand or cake board. Cover with a thin
layer of buttercream, spreading it out
evenly, then sit a second sponge on
top. Top with a layer of buttercream,
then sit the third sponge on top,
pressing down gently to adhere.
16 Cover the top and sides of the cake
with a thin crumb-coat layer of
buttercream. Chill for 15 minutes.
17 Remove from the fridge and cover
with a thicker layer of buttercream.
Return the cake to the fridge.
18 For the ganache: Place the
chocolate in a heatproof bowl. Warm
the cream with the coconut oil in a
saucepan set over a moderate heat
until it just approaches boiling point;
don't boil the mixture.
19 Pour the hot cream mixture over
the chocolate and let stand for
2 minutes. Gently whisk until the
ganache is smooth and even, letting it
cool for 10 minutes
20 Pour the ganache over the top of
the cake, letting it run down the sides.
Pipe swirls of buttercream on top of
the cake around the perimeter, sitting
the truffles on top.
