In a bowl, combine the eggs and sugar. Beat until the mixture becomes a light yellow cream.
Gradually add the vanilla extract and flour, folding gently with smooth, circular motions.
Pour the sponge cake batter into a shallow rectangular baking tray lined with parchment paper that has been greased and floured.
Bake in a preheated oven at 180°C (350°F) for about 15 minutes. Be careful not to overbake, as the cake needs to remain pliable for rolling.
Remove the sponge cake from the oven and dust it with powdered sugar. Carefully turn it out of the tray, remove the parchment paper, and roll the cake onto itself while still warm. Allow it to cool completely.
Process the chestnuts in syrup in a food processor or blender until smooth.
Transfer the chestnut purée to a bowl and add the heavy cream, which should be whipped to soft peaks with the powdered sugar beforehand. Mix well.
Finally, fold in the melted chocolate. Chill the filling in the refrigerator until ready to use.
Melt the couverture chocolate in a double boiler (bain-marie).
Remove from heat and gradually add the powdered sugar, stirring constantly until smooth.
Unroll the cooled sponge cake and spread the chestnut and chocolate cream evenly over the surface. Roll the cake back up tightly.
Cover the rolled cake with the chocolate topping and refrigerate.
Ensure the sponge cake is not overbaked, as it needs to remain pliable for rolling.
Whip the heavy cream to soft peaks for a light and airy filling.
Chill the filling before spreading it on the sponge cake to make it easier to handle.
Use a serrated knife to slice the rolled cake cleanly.
Can I use fresh chestnuts instead of chestnuts in syrup?
Yes, but you will need to cook and sweeten them before using them in the recipe.
How do I prevent the sponge cake from cracking while rolling?
Roll the sponge cake while it is still warm and pliable, and handle it gently.
Can I make this cake in advance?

What is couverture chocolate, and can I substitute it?
Couverture chocolate is high-quality chocolate with a higher cocoa butter content. You can substitute it with regular chocolate, but the texture may differ slightly.
Can I freeze the rolled cake?
