Festive Chocolate and Hazelnut Yule Log

FESTIVE CHOCOLATE YULE LOG

"A family favourite that never fails to impress—this chocolate Yule log features a light, tender chocolate sponge rolled around a dreamy chocolate mascarpone cream, all wrapped in a silky chocolate ganache. Perfectly chocolatey, festive, and irresistible, it’s the centrepiece your holiday table deserves."

INGREDIENTS

FOR THE CHOCOLATE SPONGE

4 medium eggs

115g (4oz) golden caster sugar

3 tbsp vanilla bean paste

90g (4oz) plain flour

25g cocoa

35g chopped hazelnuts 

 

FOR THE FILLING

 

125g Mascarpone

300ml Double or heavy cream

100g Melted chocolate 70% cocoa silds

40g blanched hazelnuts (toasted) - chopped 

50g golden caster sugar

 

FOR THE GANACHE FROSTING

200g Chocolate -70% cocoa solids

20g Unsalted butter

200ml Double or heavy cream

20g Golden syrup

 

METHOD

Make the sponge – line a 20 x 30cm shallow baking tin with non-stick baking parchment and preheat the oven to 180C

 

Whisk the eggs together with the sugar until light and ribbony.  Add the vanilla, then sift in the flour and cocoa together.  Fold in with a spatula and drizzle the melted butter around the bowl.  Fold in and then transfer to the prepared tin, level the surface, sprinkle with the hazelnuts and bake in the oven for 10 minutes until risen and springy to touch.  Place the remaining hazelnuts in a shallow baking tin and place in the oven at the same time, to toast for 10 minutes.  

Lay a cold, wet, clean tea towel on the work surface, with a fresh sheet of non-stick baking parchment on top, sprinkled with a little golden caster sugar.  Turn the sponge out straight away and while hot, roll up from the long side, keeping the paper inside.  Wrap in the tea towel and set on a cooling rack until cooled. 

Meanwhile, make the mascarpone filling.  Place the mascarpone, cream, sugar and vanilla in the bowl of a stand mixer and gently whisk until they just come together.  Add the melted chocolate to create a stracciatella filling.

 

TO ASSEMBLE 

Unravel the cake roll but keep the sponge on the baking parchment.  Spread the stracciatella filling over the top of the yule log to the edges.  Sprinkle with the chopped toasted hazelnuts. Carefully reroll the cake and use the baking parchment to lift and transfer the yule log to a rectangular board. 

 

FOR THE GANACHE

Break the chocolate into a bowl. Heat together the cream and syrup in a saucepan until they just come to the boil then pour over the chocolate.  Leave to stand for 1 minute, then stir until melted.  Add the softened unsalted butter and beat until thickened and glossy.  

Spread generously over the top, sides and ends of the yule log then transfer to a presentation board, decorated with pine fronds and Christmas baubles and stars. 

 

This yule log will serve 8-10 portions, keep for up to 3 days in the fridge or can be frozen for up to 1 month.  Defrost in the fridge and enjoy at room temperature.
