How to Make Opéra

Tap a step to highlight it, or turn on Cook Mode for large type and step-by-step focus.

  1. Whisk the ground almonds, icing sugar and whole eggs for 8 minutes until pale and tripled. Fold in the flour, then the whites whipped with the caster sugar, then the melted butter.

  2. Spread thinly over two lined 30 x 40 cm trays and bake at 220°C / 425°F for 7 minutes only. Cool, then cut into three equal rectangles.

  3. Boil the espresso and sugar, cool, and add the liqueur.

  4. For the buttercream, boil the sugar and water to 118°C / 244°F, pour onto the whisking yolks, and beat until cool. Beat in the butter and the coffee.

  5. Melt the ganache chocolate into the hot cream, add the butter, and cool until spreadable.

  6. Layer in a frame: sponge, soak with syrup, half the buttercream, sponge, syrup, ganache, sponge, syrup, the rest of the buttercream. Chill 60 minutes between each layer.

  7. Melt the glaze chocolate with the oil, pour over the chilled cake, tilt to level, and chill 120 minutes. Trim all four edges with a hot knife.

Worth Knowing

  • Chill between every single layer. This is a two-day cake.
  • Seven minutes for the sponge — it must stay flexible.
  • Trim the edges with a hot knife for the stripes.

Behind the Recipe

Everything depends on each layer being genuinely flat and each one being set before the next goes on, so this is a dessert made over two days and chilled between every stage. The joconde sponge is baked thin and fast — seven minutes — so it stays flexible enough to layer without cracking. Trim the edges with a hot knife at the end, which is what gives the clean striped section the cake is judged on.

Serving Ideas

Quick Answers

How long does Opéra take to make?

1 hour 15 minutes of preparation and 25 minutes of cooking, plus 3 hours of chilling between every layer, so allow 4 hours 40 minutes from start to finish. The method also needs time for cooling the sponge, which it does not time, so treat that as a minimum. The recipe serves 12.
