Ingredients
- Almond flour (Poudre d’Amandes)
- Icing sugar
- 4 Large eggs (room temperature)
- 2 Egg whites (room temperature)
- All-purpose flour
- Unsalted butter (melted and cooled)
- Dark chocolate (at least 60% cocoa)
- Heavy cream
- Unsalted butter (softened for buttercream)
- Granulated sugar
- Coffee extract
- Water
Instructions
- Preheat oven to 180°C (350°F) and line a baking sheet with parchment paper.
- In a large bowl, whisk together almond flour, icing sugar, and 4 whole eggs until thick and pale.
- Whip 2 egg whites to stiff peaks in a separate bowl, then fold into the almond mixture.
- Gently fold in the sifted flour and melted butter, spread onto the baking sheet, and bake for 10-12 minutes until golden; let cool.
- Prepare ganache by pouring hot, simmering heavy cream over chopped dark chocolate; stir until smooth and chill until spreadable.
- Create coffee buttercream by whisking eggs and sugar over a bain-marie until warm, then whipping until cool and thick before slowly adding softened butter and coffee extract.
- Simmer water, sugar, and coffee extract to create a soaking syrup; allow to cool.
- Assemble the cake by cutting the sponge into three rectangles, brushing each with syrup, and layering with buttercream and ganache.
- Melt remaining chocolate and butter for the glaze, spread smoothly over the top, and chill for at least two hours.
- Trim the edges with a hot, dry knife to reveal clean layers before serving.
Notes
For the cleanest slices, ensure the cake is thoroughly chilled for at least two hours before trimming the edges with a hot, dry knife. If your coffee buttercream appears to curdle during mixing, simply continue whipping it at a high speed until the butter emulsifies into a smooth, silky consistency.
