INSTRUCTIONS (how to make this recipe):
Make the sheetcake
Preheat the oven to 180 degrees Celsius / 355 Fahrenheit top and bottom heat.
Beat the eggs with the sugar for 10 minutes in a food processor or with a whisk until thick and pale.
Sift the flour, baking powder, cocoa and salt into the beaten eggs. Mix together gently with a spatula.
Line a baking sheet with parchment paper and pour in the mixture. Bake for 13 minutes. When cooked, leave to cool for 10 minutes.
Turn the cake out onto a sheet of parchment paper and carefully roll up*. Leave to cool for a further 10 minutes.
Make the filling
Whip the whipping cream with the powdered sugar until stiff. Beat the mascarpone and add to the whipped cream, mixing gently.
Roll out the cake again and spread with the whipped cream and mascarpone mixture. Roll up the cake carefully and tightly.
Make the topping
Melt the chocolate au bain marie with the unsalted butter. Whisk until smooth and spread over the sides and top of the Bûche de Noël.
Decorate with chocolate shavings or grated chocolate. If necessary, allow the Bûche de Noël to set in the fridge before serving, then dust with powdered sugar. Enjoy!
Good to know:
*Tip: Lightly moisten a tea towel and roll the cake in it to cool, this will prevent the cake from breaking easily when rolled.
