Ingredients
Scale
Sponge
- 3/4 cup almond flour
- 1/4 cup all-purpose flour
- 4 large eggs
- 1/2 cup sugar
- 1/2 cup butter, melted
- 1/4 cup brewed coffee
Glaze
- 1/2 cup dark chocolate
- 1/2 cup heavy cream
Coffee Buttercream
- 1/2 cup melted butter
- 1/4 cup brewed coffee
- Optional: powdered sugar to thicken
Instructions
- Preheat and Prepare Pan: Preheat your oven to 350°F (175°C). Grease a baking sheet thoroughly and line it with parchment paper to prevent sticking.
- Whisk Eggs and Sugar: In a large mixing bowl, whisk together the eggs and sugar vigorously for 5–7 minutes until the mixture becomes thick, pale, and fluffy, indicating good aeration.
- Fold in Flours: Gently fold the almond flour and all-purpose flour into the egg mixture. Do this carefully to maintain the airiness and prevent deflating the batter.
- Bake the Sponge: Pour the batter evenly onto the prepared baking sheet and spread it out uniformly. Bake for 12–15 minutes until the sponge turns golden and a toothpick inserted into the center comes out clean. Allow it to cool completely.
- Slice the Sponge: Once cooled, slice the sponge carefully into three even layers to prepare for assembly.
- Make Coffee Buttercream: Combine melted butter and brewed coffee in a bowl. If you prefer a thicker buttercream, add powdered sugar gradually until desired consistency is achieved.
- Assemble Cake Layers: Spread a layer of coffee buttercream on the first sponge layer, then stack the next sponge on top. Repeat layering with buttercream until all three layers are stacked and covered.
- Prepare Chocolate Glaze: Heat the dark chocolate and heavy cream together gently until melted and smooth. Let the mixture cool slightly to thicken before pouring it evenly over the top of the assembled cake.
- Chill to Set: Refrigerate the finished cake for at least 1 hour to allow the glaze and buttercream to set properly before serving.
Notes
- For extra coffee flavor, consider lightly brushing each sponge layer with additional brewed coffee before spreading buttercream.
- Ensure the sponge layers are completely cool to prevent melting the buttercream during assembly.
- The powdered sugar in the buttercream is optional but helps achieve a firmer consistency if preferred.
- Store the Opera Cake in the refrigerator and consume within 3 days for optimal freshness.
- To serve, allow the cake to sit at room temperature for 10–15 minutes for a softer texture.
