Detailed Directions and Instructions

Prepare Coffee Syrup

In a small saucepan, combine coffee, sugar, and water. Heat over medium until the sugar dissolves. Allow it to cool, then set aside.

Make the Jaconde Sponge

Preheat your oven to 220°C (428°F). In a mixing bowl, beat the egg whites until stiff peaks form. In another bowl, whisk the almond powder, icing sugar, and whole eggs until light and fluffy. Carefully fold the whipped egg whites into the almond mixture, and then fold in the melted butter. Finally, mix in the flour until well incorporated.

Bake the Sponge

Spread the batter onto a parchment-lined baking sheet, smoothing it into an even layer. Bake in the preheated oven for approximately 8-10 minutes. Once baked, remove it from the oven and cool before cutting into three equal parts.

Prepare the Ganache

Heat the cream in a saucepan until just boiling. Pour it over the chopped dark chocolate and let it sit for a minute. Stir until smooth and glossy. Allow the ganache to cool until it thickens.

Make the Buttercream

In a mixing bowl, beat softened butter until light and creamy. Gradually add the sugar and cooled coffee. Mix well, then incorporate the cooled ganache until smooth.

Assemble the Cake

Place the first layer of Jaconde onto a serving plate and brush it generously with coffee syrup. Spread a layer of coffee buttercream on top, followed by a layer of ganache. Repeat this process with the second layer and then place the final layer on top. Use the remaining buttercream to coat the sides and top of the cake.

Chill the Cake

Refrigerate the assembled cake for several hours or overnight to allow the flavors to meld and the cake to firm up.

Finish with Glaze

Prepare a chocolate glaze by heating cream and mixing with chocolate until smooth. Pour over the chilled cake, allowing it to drip down the sides. Allow the glaze to set before slicing.

Notes

Storage

The Opéra cake can be stored in the refrigerator for up to 3 days.

Serving Tip

Flavor Variation

Cook techniques

Making Coffee Syrup

To create a rich coffee syrup, brew strong coffee and combine it with sugar over heat until it thickens. This syrup adds depth to the cake layers.

Preparing Ganache

Heat cream until simmering and pour it over chopped chocolate. Stir until smooth to create a glossy ganache that will be used for frosting and filling.

Layering the Cake

Alternate layers of almond sponge cake, coffee syrup, and buttercream, ensuring even distribution. This technique helps achieve a balanced flavor profile in each slice.

Frosting Techniques

Apply a thin layer of ganache to the outer layer of the cake. Use a spatula to create a smooth finish, which will enhance the final presentation of the dessert.

Chilling the Cake

After assembling, refrigerate the cake to allow the layers to set properly. This helps in producing clean slices when it’s time to serve.

Garnishing

Decorate with chocolate shavings or a dusting of cocoa powder for a refined touch. This finishing technique enhances visual appeal and adds texture.
