A round, party-sized opera torte: four thin layers of almond sponge brushed with coffee syrup and filled with a whipped coffee and dark chocolate ganache, then covered in a smooth chocolate glaze. It is a simpler cousin of the rectangular opera cake, with no buttercream.

Cross-Contamination Warning for Gluten-Free Opera Torte: When preparing this desserts recipe, instant espresso powder and some chocolate are made on shared lines with products that contain gluten, so check those labels. Flour dust travels. Bake this on a day the kitchen is not also handling flour that contains gluten, use clean bowls, beaters and baking sheets, and keep the gluten-free flour blend in its own sealed container.

Gluten-Free Notes for Gluten-Free Opera Torte: The sponge is built on almond flour with a little gluten-free all-purpose flour blend instead of flour that contains gluten. Use almond flour, chocolate, instant espresso, baking powder and a flour blend labeled gluten-free.

Instructions

1 Make the whipped ganache first: heat 2 cups cream with the espresso powder until steaming, pour over 6 oz chocolate, wait 2 minutes and stir smooth. Cover and refrigerate for at least 4 hours, until very cold.
2 Preheat the oven to 350°F (175°C). Grease two 8-inch round cake pans and line the bottoms with parchment.
3 Beat the egg yolks with 6 tbsp of the sugar until thick and pale, about 3 minutes. Whisk the almond flour, gluten-free flour blend, baking powder and salt together.
4 Whip the egg whites to soft peaks, add the remaining 6 tbsp sugar and whip to firm, glossy peaks.
5 Fold a third of the whites into the yolks, then fold in the dry ingredients and the remaining whites in alternating additions. Fold in the melted butter and divide the batter between the pans.
6 Bake for 20-24 minutes, until golden and a toothpick comes out clean. Cool for 10 minutes, turn out and cool completely. Split each cake in half horizontally to make 4 thin layers.
7 Whip the cold ganache on medium just until it holds soft peaks, about 1-2 minutes. Do not overwhip, or it turns grainy.
8 Place one layer on a cake board, brush with coffee syrup and spread with a quarter of the whipped ganache. Repeat with the remaining layers, finishing with a thin coat of ganache over the top and sides. Chill for 1 hour.
9 For the glaze, heat 1/2 cup cream until steaming, pour it over 4 oz chocolate and stir smooth. Cool to about 90°F (32°C) and pour it over the chilled torte, letting it run down the sides. Chill for 1 hour before slicing.

Tips & Notes

Chill the ganache for the opera torte until it is completely cold before whipping. Warm ganache will not hold peaks and slides off the layers.
Use a long serrated knife to split the sponge layers and turn the cake as you cut. Even, thin layers keep the opera torte level.
The opera torte slices best after an overnight rest in the fridge. Take it out 20 minutes before serving so the ganache softens slightly.
