Ingredients

Almond Sponge (Joconde)

• 3 large eggs
• 3 egg whites
• 2 tablespoons granulated sugar
• 3 tablespoons all-purpose flour
• 2 tablespoons melted butter

Coffee Syrup

• 1 cup water
• 1 cup granulated sugar
• 2 tablespoons instant espresso powder

French Coffee Buttercream

• 3 large egg yolks
• 1 cup granulated sugar
• 1 4 cup water
• 1 cup unsalted butter softened
• 1 tablespoon instant espresso dissolved in 1 tablespoon hot water

Chocolate Ganache Layer

• 1 cup heavy cream
• 1 12 cups chopped dark chocolate

Chocolate Glaze

• 12 cup heavy cream
• 1 cup chopped dark chocolate
• 1 tablespoon light corn syrup

Step-By-Step Instructions

1. Line a baking sheet with parchment and preheat the oven to 400°F (200°C).
2. Make the almond sponge by whisking almond flour, powdered sugar, and whole eggs until thick and pale.
3. In a separate bowl, whip egg whites and granulated sugar until stiff peaks form.
4. Fold the whipped egg whites into the almond mixture, then fold in flour and melted butter.
5. Spread the batter evenly on the baking sheet and bake for 8–10 minutes until lightly golden.
6. Prepare the coffee syrup by simmering water, sugar, and espresso until fully dissolved. Cool completely.
7. For the buttercream, whip egg yolks in a stand mixer. Heat sugar and water to a soft-ball stage, then pour over yolks while mixing.
8. When the mixture cools, add softened butter a little at a time until creamy. Mix in dissolved espresso.
9. Make the ganache by heating cream until steaming, then stirring in chopped chocolate until smooth.
10. Trim the sponge into three equal rectangles.
11. Place the first layer on a tray and brush generously with coffee syrup. Spread on half the buttercream.
12. Add the second sponge layer, brush again with syrup, and spread the ganache. Chill 10 minutes to set.
13. Add the final sponge layer, brush lightly with syrup, and spread the remaining buttercream.
14. Chill for 20 minutes.
15. Make the glaze by heating cream and stirring in chocolate and corn syrup. Pour evenly over the top.
16. Chill at least 3 hours or overnight before slicing.

Tips & Variations

• Cool each layer fully before assembling to ensure clean, sharp edges.
• Use high-quality chocolate for the richest flavor.
• Replace espresso with decaf if desired.
• Chill the cake between layers to prevent shifting.
• Add a thin line of gold leaf on top for a professional pâtisserie look.

Storage & Freezer Instructions

• Store the assembled Opera Cake in an airtight container in the refrigerator for up to 4 days.
• Keep the cake chilled until ready to slice; this helps maintain clean layers.
• Avoid storing the cake at room temperature because the buttercream softens quickly.
• For freezing, wrap individual slices in plastic wrap, then place them in a freezer-safe container.
• Freeze for up to 2 months without affecting texture or flavor.
• Thaw overnight in the refrigerator before serving to preserve the layered structure.

Serving & Pairing Ideas

• Serve with espresso, cappuccino, or strong black tea.
• A small scoop of vanilla ice cream complements the richness.
• Add fresh berries for color and brightness.
• Serve chilled for the cleanest layers and best texture.

Frequently Asked Questions

Can I make opera cake ahead of time?

Yes, this cake benefits from resting time. The flavors deepen and the layers firm up, making slicing easier. Prepare it up to two days ahead and store it covered in the refrigerator.

Do I have to use almond flour for the sponge?

Almond flour is essential for the traditional texture. It gives the sponge its tender crumb and signature flavor. Other flours will change the structure and may not hold up to the layered design.

Why did my buttercream separate?

This usually happens when the butter or syrup mixture is too warm or too cold. Keep mixing; it often comes back together as the temperature evens out. You can briefly warm the bowl sides with your hands if needed.

Can I replace the coffee flavor?

Yes, you can swap the espresso with cocoa powder dissolved in water. This creates a chocolate-forward version while keeping the structure intact.
