Method
 

Prepare the Almond Joconde Sponge Cake
  1. Preheat oven to 425°F (220°C). Line one 12×17 inch (30×43 cm) baking sheet with parchment paper.
  2. In a stand mixer with the whisk attachment, beat egg whites until foamy. Gradually add 1/4 cup (50g) granulated sugar and beat until stiff, glossy peaks form. Transfer to a separate bowl and set aside. Clean the mixer bowl and whisk.
  3. In the clean mixer bowl, combine whole eggs, almond flour, powdered sugar, and all-purpose flour. Beat on medium-high speed for 5-7 minutes, until light, airy, and tripled in volume.
  4. Gently fold in the melted butter and vanilla extract into the almond mixture.
  5. Carefully fold in about one-third of the whipped egg whites into the almond mixture to lighten it, then gently fold in the remaining egg whites until just combined, being careful not to deflate the batter.
  6. Spread the batter evenly onto the prepared 12×17 inch baking sheet. Bake for 8-10 minutes, or until light golden brown and springy to the touch.
  7. Immediately invert the cake onto a clean sheet of parchment paper, peel off the baking parchment, and let cool completely on a wire rack. Once cooled, use a ruler and sharp knife to trim the edges, then cut the large cake into three equal 8×12 inch (20×30 cm) rectangles. Set aside.
Prepare the Coffee Syrup
  1. In a small saucepan, combine brewed coffee and granulated sugar. Bring to a simmer over medium heat, stirring until sugar dissolves completely. Remove from heat and stir in coffee liqueur (if using). Let cool completely.
Prepare the French Coffee Buttercream
  1. In a stand mixer bowl, whisk egg yolks until pale and thick.
  2. In a small saucepan, combine granulated sugar and water. Bring to a boil over medium-high heat. Cook without stirring until the syrup reaches 240°F (115°C) on a candy thermometer (soft ball stage).
  3. With the mixer running on low speed, slowly and carefully pour the hot sugar syrup in a thin stream into the egg yolks. Increase speed to high and beat for 8-10 minutes, until the mixture is very thick, light in color, and the bowl is cool to the touch.
  4. Reduce mixer speed to medium-low. Add the room temperature butter, one cube at a time, beating well after each addition until fully incorporated. The mixture may look curdled at first, but keep beating until it comes together into a smooth, fluffy buttercream.
  5. Stir in the dissolved espresso powder and vanilla extract. Beat until fully combined. If the buttercream is too soft, refrigerate for 15-20 minutes, then re-beat. If it’s too firm, let it sit at room temperature for a bit, then re-beat.
Prepare the Chocolate Ganache (First Layer)
  1. Place chopped dark chocolate in a heatproof bowl.
  2. Heat heavy cream in a small saucepan until simmering (just before boiling). Pour hot cream over the chocolate. Let sit for 5 minutes, then whisk until smooth and shiny.
  3. Stir in the unsalted butter until melted and fully incorporated. Let the ganache cool slightly at room temperature until it thickens to a spreadable consistency (about 30-45 minutes), but is not too firm.
Assemble the Opera Cake
  1. Place one 8×12 inch Joconde cake layer on a serving platter or a sturdy cardboard base. If using a cake ring, place it around the cake layer.
  2. Brush the cake generously with about one-third of the cooled coffee syrup.
  3. Spread half of the chocolate ganache evenly over the syrup-soaked cake layer. Chill in the refrigerator for 15 minutes to set the ganache slightly.
  4. Once chilled, spread half of the coffee buttercream evenly over the ganache layer. Level with an offset spatula.
  5. Place the second Joconde cake layer on top. Brush generously with another one-third of the coffee syrup.
  6. Spread the remaining coffee buttercream evenly over the second cake layer. Level with an offset spatula.
  7. Place the third and final Joconde cake layer on top. Brush generously with the remaining coffee syrup.
  8. Spread the remaining chocolate ganache evenly over the top of the third cake layer. Level smoothly.
  9. Refrigerate the entire cake for at least 1-2 hours, or preferably overnight, to allow the layers to set firmly and flavors to meld. This is crucial for clean cutting.
Prepare the Chocolate Glaze (Glaçage Opéra)
  1. Place chopped dark chocolate in a heatproof bowl.
  2. In a small saucepan, combine heavy cream, water, granulated sugar, and corn syrup. Bring to a boil over medium-high heat, stirring until sugar is dissolved. Continue to boil for 1-2 minutes.
  3. Remove from heat and pour the hot syrup mixture over the chopped chocolate. Let sit for 5 minutes, then whisk gently from the center outwards until completely smooth and shiny. Stir in vanilla extract.
  4. Let the glaze cool slightly until it reaches about 95-100°F (35-38°C). It should be fluid but not hot.
Glaze the Cake
  1. Remove the chilled cake from the refrigerator. If using a cake ring, carefully warm the sides with a hot towel or blow dryer to release, then remove the ring.
  2. Place the cake on a wire rack set over a baking sheet (to catch excess glaze).
  3. Pour the slightly warm chocolate glaze evenly over the top of the cake, starting from the center and working outwards, allowing it to drip down the sides. Use an offset spatula to gently guide the glaze to cover all sides if needed, but avoid overworking it.
  4. Allow the glaze to set for about 15-30 minutes at room temperature, or briefly in the refrigerator until firm to the touch.
  5. Trim any excess glaze from the bottom edges using a thin, hot knife.
  6. For a classic finish, pipe “Opéra” in melted white chocolate or apply edible gold leaf onto the center of the glaze.

Notes

For the cleanest slices, ensure the cake is very cold before cutting. Dip a sharp, thin knife in hot water and wipe clean between each slice. Opera cake is best served chilled. Store leftovers in an airtight container in the refrigerator for up to 3-4 days. The Joconde sponge is delicate; handle with care. Ensure your eggs and butter for the buttercream are at room temperature for the best emulsion. Achieving the correct temperature for the sugar syrup in the buttercream is crucial for stability; a candy thermometer is highly recommended.

Pro Tips for Making This Opera Cake

Crafting an exquisite Opera Cake is truly a labor of love, and over the years, I’ve gathered a few treasured tips that make the process smoother and the results even more spectacular.

My Secret Trick: When making the almond joconde sponge, I always separate my eggs while they’re cold, but then let them come to room temperature before whipping the whites. This helps them achieve maximum volume, giving you that wonderfully light and airy cake base that’s essential for a perfect Opera Cake.

Don’t rush the chilling process between layers. I know it’s tempting to speed things up, but allowing each layer of buttercream and ganache to firm up in the refrigerator makes assembly so much easier and prevents the layers from sliding. Patience truly is a virtue in this kitchen!

For the coffee syrup, make sure your coffee is strong and freshly brewed. A robust coffee flavor is key to balancing the sweetness of the cake and really makes the coffee elements sing. I often use instant espresso powder mixed with hot water for a consistently intense coffee flavor.

When it comes to the chocolate glaze (Glaçage Opéra), ensure your melted chocolate and cream mixture is smooth and at the right temperature before pouring. I like to strain mine through a fine-mesh sieve to catch any tiny lumps, ensuring a flawlessly shiny finish that makes your Opera Cake look professionally made.

Fun Variations for Opera Cake

While the classic Opera Cake is a masterpiece on its own, I adore finding ways to add a personal touch or a fun twist! It’s all about making a dessert truly your own, and these variations are sure to delight.

Zesty Orange Infusion

For a refreshing change, try infusing your coffee syrup with a hint of orange zest. Just add the zest of one orange to the hot coffee syrup and let it steep for 10-15 minutes before straining. The citrus brightens the rich coffee and chocolate beautifully. My friend Sarah absolutely adores this version, saying it reminds her of sophisticated chocolate oranges!

Nutty Almond Bliss

Instead of just plain almond flour, consider adding a tablespoon of finely ground pistachios or hazelnuts to your joconde sponge for an extra layer of nutty flavor. This adds a delightful complexity and a subtle color variation that makes each bite of Opera Cake even more intriguing.

Raspberry Swirl

For a touch of fruitiness, warm a few tablespoons of good quality raspberry jam and gently swirl it into one of the chocolate ganache layers before chilling. The tartness of the raspberry cuts through the richness and adds a lovely surprise element. It’s a wonderful option for those who love a bit of fruit with their chocolate.

What to Serve With Opera Cake

An elegant dessert like Opera Cake deserves accompaniments that complement its rich flavors without overshadowing it. Think simple, delightful pairings that enhance the experience.

I love serving a slice of Opera Cake with a strong, freshly brewed cup of espresso or a dark roast coffee. The coffee notes in the cake are beautifully echoed, creating a harmonious and truly grown-up treat. It’s my go-to pairing for an after-dinner indulgence.

For something a little lighter, a small scoop of good quality vanilla bean ice cream or a dollop of unsweetened whipped cream on the side adds a lovely, cooling contrast to the rich chocolate and coffee. It’s a simple addition that feels wonderfully luxurious.

Fresh berries, like raspberries or a few small strawberries, can also be a delightful accompaniment. Their natural tartness and freshness cut through the richness of the Opera Cake, offering a bright counterpoint that cleanses the palate. My mom always pairs it with a few fresh raspberries from her garden, saying it’s like a little jewel on the plate!

How to Store Opera Cake

Once you’ve poured your heart into creating a beautiful Opera Cake, you’ll want to ensure it stays fresh and delicious! Proper storage is key to preserving its delicate flavors and textures.

Refrigerator Storage

Your Opera Cake can be stored in an airtight container in the refrigerator for up to 3-4 days. Because of the buttercream and ganache, it’s essential to keep it chilled. I like to place it on a flat plate and then cover it with a cake dome or plastic wrap, ensuring no air can get to it. This keeps the layers moist and prevents any strong odors from the fridge from affecting its delicate taste.

Freezing for Later Enjoyment

Yes, you can absolutely freeze Opera Cake! For longer storage, wrap individual slices or the entire cake tightly in several layers of plastic wrap, then an additional layer of aluminum foil. It will keep well in the freezer for up to 1 month. When you’re ready to enjoy, simply transfer it to the refrigerator to thaw overnight.

My Personal Tip: To enjoy frozen Opera Cake at its best, allow it to come to room temperature for about 15-20 minutes before serving after thawing in the fridge. This brings out the full intensity of the coffee and chocolate flavors and softens the buttercream to perfection.

Nutritional Benefits

While the Opera Cake is a decadent treat, it also offers a few pleasant surprises. Made with almond flour, it provides a good source of healthy fats and a touch of protein, making it a satisfying dessert. The dark chocolate contributes antioxidants, offering a little extra goodness to this rich creation. It’s a lovely example of how a treat can be both indulgent and made with simple, wholesome ingredients.
