Combine the egg yolks, sugar, cognac, water, and vanilla essence in a bowl. Mix everything together and cook in a double boiler, beating with an electric mixer until the mixture thickens and reaches ribbon stage. Remove from the double boiler and continue beating until the cream cools.
Melt the semi-sweet chocolate in a double boiler. Divide the egg yolk cream into two portions, and add the melted chocolate to one of them.
Whip the heavy cream to soft peaks. Add half of the whipped cream to the chocolate mixture and the other half to the plain egg yolk cream, mixing well.
Line a loaf pan with parchment paper, covering the bottom and sides, leaving some paper overhanging to make it easier to unmold the dessert later.
Cut the sponge cake into three rectangular pieces to fit the mold. Place one layer at the bottom of the mold and brush it with the strong coffee.
Spread the plain egg yolk cream over the sponge cake and sprinkle with chopped walnuts.
Add another layer of sponge cake, brush it with coffee, and spread the chocolate cream on top.
Finish with a final layer of sponge cake, also brushed with coffee.
Fold the overhanging parchment paper over the top of the dessert and refrigerate for 3 hours before unmolding.
Ensure the egg yolk mixture is cooked gently in the double boiler to avoid scrambling the eggs.
For a stronger coffee flavor, use espresso instead of regular coffee.
To make chocolate curls, use a vegetable peeler on a block of chocolate.
Refrigerate the dessert overnight for a firmer texture and enhanced flavors.
Can I use a different type of cake instead of sponge cake?
Yes, you can use any light and airy cake, but sponge cake works best as it absorbs the coffee and holds the layers well.
Can I substitute the cognac?
Yes, you can use rum, brandy, or even omit it if you prefer an alcohol-free version.
How long can I store this dessert?
You can store the dessert in the refrigerator for up to 3 days. Ensure it is covered to prevent it from drying out.
Can I make this dessert ahead of time?
Yes, this dessert is perfect for making ahead. Prepare it the day before and refrigerate until ready to serve.
Can I use milk chocolate instead of semi-sweet chocolate?
Yes, but the dessert may be sweeter. Adjust the sugar in the recipe if needed.
