Creating an Opera Cake involves several steps, but with our detailed instructions, you’ll find the process straightforward and enjoyable. Follow these steps to bake your own Opera Cake masterpiece:

1. Preheat the oven to 350°F (175°C). Grease a baking pan to prevent the cake from sticking.
2. Prepare the batter by whisking together almond flour, all-purpose flour, and sugar in a large bowl.
3. Incorporate the wet ingredients by adding the eggs and melted butter to the dry mixture. Mix until the batter is smooth and well-combined.
4. Pour the batter into the prepared baking pan, spreading it evenly. Bake for 20 minutes or until the cake is golden brown. Allow it to cool completely before proceeding.
5. Slice the baked cake horizontally into three equal layers using a serrated knife.
6. Brush each layer generously with the cooled brewed coffee, ensuring the cake absorbs the flavors.
7. Prepare the filling: Melt dark chocolate gently over a double boiler or in the microwave. In a separate bowl, whip the heavy cream until it forms soft peaks. Fold in the melted chocolate and vanilla extract until smooth and creamy.
8. Assemble the cake by spreading the chocolate filling evenly between each layer of the cake. Carefully stack the layers to maintain the structure.
9. Finish with chocolate ganache: Spread a smooth layer of chocolate ganache over the top of the cake. Refrigerate for at least 1 hour to set the flavors and textures.
