Why I Love Making Opera Cake

This creamsicle opera cake holds a special place in my baking repertoire. While traditional opera cake features coffee and chocolate, this orange-kissed version turns the French classic into something unexpectedly nostalgic – like those beloved orange creamsicle pops from childhood, but elevated into an elegant layered dessert.

I won’t lie – this is an ambitious project. But that’s exactly why I love it. The joconde sponge bakes up impossibly light, the orange buttercream spreads like silk, and that white chocolate ganache adds the perfect creamy contrast. Each component can be prepared ahead, making the final assembly feel less daunting.

What really wins me over is how this cake tastes even better the next day. Those layers of almond cake soaked in orange syrup, buttercream, and white chocolate mousse get a chance to settle together in the refrigerator, creating something truly spectacular. It’s become my signature dessert for special celebrations.

What is Opera Cake?

Opera cake is a traditional French cake made by layering almond sponge cake with buttercream frosting. On top is a shiny glaze. 

The almond sponge cake is also called joconde. It’s light and airy and gets most of its flavor from a simple syrup that you’ll brush over the top of the cake.  

Most traditional Opera Cakes are flavored with chocolate ganache and vanilla buttercream. We made a twist by adding orange flavor and white chocolate mousse. 

Ingredient Notes

Almond flour: Use finely ground blanched almond flour, not almond meal. The texture difference is significant for achieving a smooth, refined joconde.

Grand Marnier: This orange liqueur enhances the creamsicle flavor. Substitute with additional orange juice and ½ teaspoon orange extract if avoiding alcohol.

Orange gel food coloring: Just 1-2 drops in the glaze creates that signature creamsicle look. Liquid food coloring can thin the glaze too much.

Heavy cream (35%): Essential for proper ganache consistency. Lower fat content won’t whip properly or set correctly.

How to Make Orange Creamsicle Opera Cake 

To easily pull off this cake, I recommend making the joconde first and letting that cool. Then make the sugar syrup, the buttercream and the white chocolate mousse. 

Joconde

Before making the almond sponge cake, make sure you’re using fresh almond flour. Instead of a leavener like baking powder or soda, the cake rises from foamed egg whites. That’s why it’s important to very gently fold the egg whites into the batter to avoid deflating all that air. 

When pouring the batter into the baking sheet, make sure it’s lined fully with parchment paper. For good measure, give the parchment a good spray with nonstick spray too.  

Note: The cake bakes up quickly, so keep your eye on it. Ours was done in eight minutes.

How to Cut Almond Sponge Cake

To cut your cooled joconde for this opera cake, you’ll want two squares and two rectangles. The rectangles will be placed together to form a square, the middle layer. 

Simple Syrup

Prepare orange syrup by boiling water, sugar, orange juice, and extract.

Marshmallow Buttercream

The layers of almond sponge cake get spread with creamy marshmallow buttercream. This recipe is similar to a Swiss meringue buttercream. You will warm the egg whites and sugar until the sugar is dissolved, then let it cool. 

Note: The egg white mixture must be at room temperature before you add the butter or the butter will melt. You can either let it sit before whipping into a meringue or make the meringue and let it sit until at room temp.

When you add the orange juice, it’s normal that the buttercream doesn’t easily absorb the liquid. Just keep mixing until it is fully incorporated, it will come together.

White Chocolate Mousse

To make a light and fluffy white chocolate mousse layer for your opera cake, make sure your white chocolate ganache is cooled to room temperature before folding into the whipped cream. And make sure not to beat the white chocolate ganache into the whipped cream or it will separate and become unusable. Instead, gold it gently. 

Opera Cake Glaze

The glaze on this cake is a simple, but very pretty, white chocolate ganache tinted orange. 

When you add the glaze, make sure your cake is at room temperature and the glaze is at a nice pourable temperature. If it’s too warm, the glaze will melt your mousse. If it’s too cold, it will stiffen and won’t pour or spread easily.

Assembling the Opera Cake

Here is the order in which to build your creamsicle opera cake:

1. Square cake layer
2. Simple syrup
3. Buttercream
4. Layer (2) rectangle layers to create a square
5. Simple syrup
6. Buttercream
7. Square cake layer
8. Simple syrup
9. White chocolate mousse
10. Glaze

Once the cake is assembled and chilled, you’ll want to trim off some of the messy edges. Use a nice sharp serrated knife to true things up. 

For garnish, I like a sprinkle of shaved white chocolate and an orange slice.

Serving 

The cake itself cuts pretty easily with a sharp knife. For best results, run the blade under hot water before slicing. 

What to Serve With Opera Cake

This rich, elegant dessert pairs beautifully with espresso or cappuccino to balance the sweetness. For a French-inspired coffee service, offer small cups of strong coffee alongside thin slices of cake.

Fresh berries – especially raspberries or strawberries – provide a tart contrast that cuts through the buttercream richness. A simple berry compote spooned alongside each slice works wonderfully.

Champagne or sparkling wine makes this feel like a true celebration dessert. The bubbles and acidity complement the creamy layers perfectly.

For a lighter accompaniment, serve with unsweetened whipped cream or crème fraîche on the side.

Storage & Reheating Tips

Refrigerator Storage

Store covered in the refrigerator for up to 1 day. The cake actually tastes better after the layers have time to meld together overnight.

Freezing

Not recommended once assembled, as the buttercream and ganache textures change when frozen. However, you can freeze the unfrosted joconde layers wrapped tightly for up to 1 month.

Room temperature

This cake must stay refrigerated due to the buttercream and fresh cream components. Remove from refrigerator 10-15 minutes before serving for best flavor.

Make ahead

Bake joconde layers 1 day ahead and keep wrapped at room temperature. Prepare buttercream and ganache the same day and refrigerate until assembly. Assemble and glaze the cake up to 1 day before serving.

Serving temperature

Serve slightly chilled for the best texture – the buttercream should be firm but not hard, and the ganache should be creamy.
