Ingredients
- Almond sponge cake: 100g (3.5 oz) ground almonds
- Flour: 60g (2.1 oz) all-purpose flour
- Eggs: 3 large eggs (about 150g or 5.3 oz)
- Sugar: 100g (3.5 oz) granulated sugar
- Coffee syrup: 200ml (6.8 fl oz) espresso or strong brewed coffee
- Chocolate ganache: 200g (7 oz) dark chocolate (70% cocoa)
- Butter: 100g (3.5 oz) unsalted butter
- Buttercream: 150g (5.3 oz) unsalted butter, softened
- Heavy cream: 200ml (6.8 fl oz) for the ganache and buttercream
- Vanilla extract: 1 tsp (5ml)
Step-by-Step Instructions
- Prepare the Almond Sponge Cake: Preheat your oven to 180°C (350°F). Beat the eggs with granulated sugar until pale and fluffy (about 5-7 minutes). Gradually fold in the ground almonds and flour.
- Bake the Cake: Pour the batter into a lined baking dish and spread evenly. Bake for 20-25 minutes. The cake should spring back when gently pressed. Allow to cool completely.
- Make the Coffee Syrup: Simmer the brewed coffee and sugar until dissolved; let cool.
- Prepare Ganache: Heat heavy cream until just boiling and pour over chopped dark chocolate. Stir until smooth and glossy, then add butter. Let it cool until it thickens slightly.
- Make Buttercream: Beat the softened butter until creamy; gradually add powdered sugar and vanilla extract. Finally, mix in a couple of tablespoons of cold ganache to smoothen the buttercream.
- Assemble the Opera Cake: Slice the sponge cake into three equal layers. Place the first layer on a platter and brush generously with coffee syrup. Spread a layer of ganache, followed by buttercream. Repeat for the second layer.
- Final Assembly: Place the top layer of sponge, cover it entirely with ganache, and chill for 2-3 hours to set.
- Garnish and Serve: Trim the cake edges to give a clean finish and decorate with gold leaf or chocolate shavings before presentation.
Variations & Substitutions
Consider creating a vegan version using almond milk and aquafaba instead of eggs. For a gluten-free alternative, substitute the flour with almond flour. If you’re looking for flavor variations, incorporate orange zest or raspberry puree into the buttercream. For a modern twist, try layering with fruit compote or different flavored ganaches, like matcha or white chocolate.
Make Ahead, Storage & Reheating
Opera Cake can be made up to two days in advance, allowing the flavors to meld beautifully. The sponge and ganache can be prepared and stored separately in the fridge for up to 3 days. Once assembled, the cake can be wrapped tightly in plastic wrap and preserved in the refrigerator for up to a week. For optimal texture, it is best served chilled and brought to room temperature before serving.
