Opera cake: Bake a classic French dessert at home with this detailed recipe shared by Mir Hasibul, pastry chef at DoubleTree by Hilton, Gurugram, Baani Square, ahead of World Chocolate Day. This elegant French dessert features almond sponge layers soaked in coffee syrup, layered with coffee buttercream and dark chocolate ganache, all finished with a glossy chocolate glaze. It’s a rich treat perfect for impressing guests, and you can try it at home with simple ingredients.
To start, preheat your oven to 220°C and line two baking trays. For the joconde sponge, whisk almond flour, icing sugar, and whole eggs until pale. In another bowl, whip egg whites with sugar to stiff peaks. Fold flour, meringue, and melted butter into the almond mix. Spread the batter thinly on trays and bake for 6-8 minutes. Cool the sponge and cut it into three equal layers.
Next, make the coffee syrup by boiling water and sugar, then stirring in instant coffee. For the buttercream, cook sugar and water to 118°C, slowly pour into whipped egg yolks, then beat in softened butter and dissolved coffee. For the ganache, heat heavy cream, pour over chopped dark chocolate, let it sit, then stir in butter until smooth.
Assemble the Opera cake by placing a sponge layer on a tray and brushing it with coffee syrup. Spread half the buttercream, add a second layer brushed with syrup, spread all the ganache, and chill for 15 minutes. Top with the final sponge layer brushed with syrup, spread remaining buttercream, and chill for 30 minutes. Melt dark chocolate with neutral oil for the glaze, pour it over the chilled cake, and spread evenly. Chill for 10 minutes, then trim edges and slice into neat portions.
This Opera cake recipe offers a delightful blend of coffee and chocolate flavors, making it a standout dessert for any occasion. Give it a try at home and enjoy a classic French pastry experience.
