Ingredients
Scale
Almond Sponge Cake
- 3/4 cup almond flour
- 1/4 cup all-purpose flour
- 4 large eggs
- 1/2 cup sugar
Coffee Buttercream
- 1/2 cup butter, melted
- 1/4 cup brewed coffee
- Optional: powdered sugar to thicken
Chocolate Glaze
- 1/2 cup dark chocolate
- 1/2 cup heavy cream
Instructions
- Preheat and Prepare: Preheat your oven to 350°F (175°C). Grease a baking sheet and line it with parchment paper to prevent sticking and ensure even baking.
- Whisk Eggs and Sugar: In a bowl, whisk the eggs and sugar together vigorously for 5–7 minutes until the mixture becomes thick, pale, and fluffy, which will provide volume and lightness to the sponge.
- Fold in Flours: Gently fold the almond flour and all-purpose flour into the egg-sugar mixture, being careful not to deflate the air incorporated in the batter to keep the sponge light.
- Bake the Sponge: Pour the batter evenly onto the prepared baking sheet. Bake for 12–15 minutes or until the top turns golden and a toothpick inserted comes out clean. Allow the sponge to cool completely.
- Slice Sponge Layers: Once cooled, carefully slice the sponge into three even layers for the cake assembly.
- Make Coffee Buttercream: Combine the melted butter and brewed coffee. Optionally add powdered sugar to the mixture to achieve a thicker buttercream consistency suitable for spreading.
- Assemble the Cake: Layer the sponge cake with coffee buttercream between each layer, spreading evenly to create distinct layers of flavor and texture.
- Prepare Chocolate Glaze: Heat the dark chocolate and heavy cream together until smooth and glossy. Allow the glaze to cool slightly before pouring it over the top of the assembled cake for a flawless finish.
- Set the Cake: Refrigerate the completed Opera Cake for at least 1 hour to allow the layers and glaze to set properly, making slicing and serving easier.
Notes
- For a firmer buttercream, add powdered sugar gradually until desired consistency is reached.
- Use high-quality dark chocolate for the best glaze flavor and texture.
- If you prefer stronger coffee flavor, consider brushing the sponge layers lightly with additional brewed coffee before layering with buttercream.
- Ensure the chocolate glaze is not too hot before pouring to avoid melting the buttercream layers.
- Store the cake covered in the refrigerator and consume within 3 days for optimal freshness.
