Luxurious French Opera Cake With Chocolate and Coffee Layers

Opera cake is the neat rectangular stack of almond sponge, coffee cream, and chocolate ganache, each layer thin and even. I soak the sponge lightly so the coffee comes through without making it soggy.

The French Opera Cake Recipe is intricate but rewarding, offering a great way to showcase your baking skills. Each layer complements the others, creating a harmonious blend of chocolate and coffee that is truly delightful.

This Opera Cake consists of multiple layers, including Joconde (an almond sponge cake), coffee buttercream, and chocolate ganache. It typically serves around 10-12 people and requires some advanced baking techniques.

Ingredients

For the Almond Sponge Cake (Joconde):
4 large eggs
110g powdered sugar
100g almond flour
30g all-purpose flour
3 large egg whites
30g granulated sugar
30g unsalted butter, melted
For the Coffee Buttercream:
200g unsalted butter, softened
100g powdered sugar
60ml brewed coffee, cooled
For the Chocolate Ganache:
200g dark chocolate, chopped
200ml heavy cream
For the Coffee Syrup:
150ml brewed coffee
75g granulated sugar
For Garnish:
Dark chocolate shavings
Coffee beans (optional)

Instructions

Make the Almond Sponge Cake: Preheat the oven to 375°F (190°C). In a bowl, whisk together the eggs and powdered sugar until thick and pale. Fold in almond flour and all-purpose flour, then gently fold in stiffly beaten egg whites and melted butter. Spread the batter onto a parchment-lined baking sheet and bake for 10-12 minutes, until golden. Allow to cool.
Prepare the Coffee Buttercream: In a mixing bowl, beat softened butter and powdered sugar until fluffy. Gradually add the cooled coffee and mix until smooth and well combined.
Make the Chocolate Ganache: Heat heavy cream in a saucepan until just simmering. Pour over chopped dark chocolate and let sit for a few minutes, then whisk until smooth. Let it cool until it thickens slightly.

Prepare the Coffee Syrup: Combine brewed coffee and sugar in a small saucepan over medium heat. Stir until sugar dissolves, then remove from heat and let cool.
Assemble the Cake: Cut the cooled sponge cake into equal-sized rectangles. Soak each layer lightly with coffee syrup. Spread a layer of coffee buttercream over the first sponge layer, then add another sponge layer, followed by chocolate ganache. Repeat until all layers are used, finishing with chocolate ganache on top.
Chill and Decorate: Refrigerate the assembled cake for at least 4 hours or overnight. Once set, decorate the top with dark chocolate shavings and coffee beans if desired. Slice and serve!
