Equipment
Ingredients
- 1.6kg (3lb 8oz) dark chocolate (60–70% cocoa), chopped
- 30 extra-large eggs, separated
- 8 extra-large eggs, whole
- 1.25kg (2lb 12oz) caster sugar
- 840g (1lb 13½oz) almond flour
- 7½ tsp strong black coffee, cooled
- 225g (8oz) apricot jam, sieved, for brushing under the frosting
- 1.25kg (2lb 12oz) dark chocolate, chopped (for frosting)
- 450g (1lb) unsalted butter, softened (for frosting)
- Fresh edible flowers and foliage (to decorate – optional)
Customise
- Scale down: Use just one or two tiers to match your crowd.
- Boozy twist: Add 1 tbsp brandy or orange liqueur to the frosting for extra depth.
- Dairy-free: Use dairy-free chocolate and vegan butter in the frosting (results may be a little less glossy).
- Decorate differently: Top with gold leaf, berries, or sugared herbs instead of flowers.
Method
- Prepare the tins:
Grease and line 6”, 9”, and 12” round cake tins with parchment. Preheat your oven to 190°C (375°F). - Melt the chocolate:
Gently melt 1.6kg (3lb 8oz) dark chocolate over a bain-marie or in short bursts in the microwave. Allow it to cool slightly but not set. - Whisk eggs and sugar:
In a very large bowl, whisk 30 egg yolks and 8 whole eggs with 1.25kg (2lb 12oz) caster sugar until pale, thick, and fluffy. - Combine dry mix:
Stir in melted chocolate, almond flour, and black coffee. Mix until just combined. - Whisk egg whites:
In a separate, clean bowl, whisk 30 egg whites until stiff peaks form (but not dry). Gently fold the whites into the chocolate mixture in three additions, taking care not to knock out the air. - Bake each tier:
Divide the batter evenly between the tins. Bake as follows: 6-inch: 45 mins; 9-inch: 1–1¼ hrs; 12-inch: 1½–1¾ hrs (cover with foil after 1 hr). Cakes are ready when a skewer tests clean and the centre is 95°C. - Cool the cakes:
Cool cakes in their tins, then transfer carefully to wire racks to cool completely. - Prepare the cakes for frosting:
Push sieved apricot jam evenly over the tops and sides of cooled cakes. This sharpens the flavour and helps the frosting to adhere. - Make chocolate frosting:
Melt 1.25kg (2lb 12oz) dark chocolate, allow to cool slightly, then gradually stir in 450g (1lb) unsalted butter until smooth and glossy. - Frost the cakes:
Set cakes on wire racks above trays. Pour over the frosting, smoothing tops and sides with an offset palette knife for a silky finish. Let the ganache set before moving the cakes. - Assemble and decorate:
Transport tiers separately. Stack at the venue using support boards if needed. Decorate with edible flowers or your chosen toppings.
What can you serve with this
- Fresh berries or berries compote: Their tartness brightens the chocolate richness.
- Lightly whipped cream: A cool, airy complement to the dense, fudgy cake.
- Strong black coffee or espresso: Enhances the chocolate and balances the sweet richness.
