Timing

Making Opera Cake takes about 30 minutes for preparation, 30 minutes for baking, and additional time for assembling and chilling.

Instructions

Step 1: Prepare the Joconde

1. Preheat Oven: Preheat your oven to 375°F (190°C). Line a half-sheet pan (18×13 inches) with parchment paper.
2. Mix Dry Ingredients: In a bowl, sift together almond flour, all-purpose flour, and powdered sugar.
3. Whip Eggs: In a separate bowl, whisk together the eggs until frothy. Gradually add the dry mixture and mix until combined.
4. Beat Egg Whites: In another bowl, beat the egg whites until soft peaks form. Gradually add granulated sugar and continue beating until stiff peaks form.
5. Combine Mixtures: Gently fold the beaten egg whites into the almond mixture. Finally, fold in the melted butter and vanilla extract.
6. Bake: Spread the batter evenly in the prepared pan and bake for 10-12 minutes, or until golden and springy to the touch. Let it cool completely.

Step 2: Make the Coffee Syrup

1. Combine Ingredients: In a small saucepan, combine brewed coffee and granulated sugar. Heat over low heat until the sugar dissolves. Stir in the coffee liqueur (if using) and let it cool.

Step 3: Prepare the Coffee Buttercream

1. Beat Butter: In a mixing bowl, beat the softened butter until creamy.
2. Add Sugar and Coffee: Gradually add powdered sugar, followed by brewed coffee and vanilla extract. Beat until smooth and fluffy.

Step 4: Make the Dark Chocolate Ganache

1. Heat Cream: In a saucepan, heat the heavy cream until it just begins to simmer.
2. Melt Chocolate: Pour the hot cream over the chopped dark chocolate and let it sit for 5 minutes. Stir until smooth.

Step 5: Assemble the Cake

1. Cut the Joconde: Once the Joconde has cooled, cut it into three equal rectangles.
2. Layering: Place one layer of Joconde on a serving platter. Brush generously with coffee syrup. Spread a layer of coffee buttercream over it.
3. Repeat Layers: Add the second layer of Joconde, brush with coffee syrup, and spread a layer of ganache over it. Add the final layer of Joconde, brush with syrup, and spread the remaining coffee buttercream on top.
4. Chill: Refrigerate the assembled cake for at least 1 hour to set.

Step 6: Glaze the Cake (Optional)

1. Make Glaze: In a saucepan, heat the heavy cream until simmering. Pour it over the chopped dark chocolate and let it sit for 5 minutes. Stir until smooth.
2. Glaze Cake: Pour the glaze over the chilled cake, spreading it evenly. Let the glaze set before slicing.

Step 7: Serve

1. Garnish: Optionally, decorate with chocolate shavings or coffee beans.
2. Enjoy: Slice and serve your beautiful Opera Cake!
