Chocolate & cinnamon marble cake

Here is the recipe of a cake made a few weeks ago but whose recipe I had only put in my stories on Instagram. I liked this cake so much that I wanted to put it here too so that the recipe would be more accessible and maybe easier to follow for those interested ! So it's a hot chocolate inspired cake, a chocolate and cinnamon marble cake filled with a creamy cinnamon caramel, covered with a milk chocolate and hazelnut icing and some whipped cream. Don't panic, if you don't have the cake mould with insert, you can simply pipe or spread the creamy caramel on the cold cake, then freeze the whole thing before pouring the icing.



Prep time : 1 heure + 1h10 cooking + time for cooling down
For a 20cm cake | 8 servings :

The cake batter :

120g softened butter
200g sugar
A big pinch of salt
2 eggs
7g baking powder
75g flour T55 + 3g cinnamon powder (1)
130g T55 flour + 25g cocoa powder (2)
65g liquid cream (1)
135g liquid cream (2)

Mix the butter, sugar and salt.




Add the baking powder and then the eggs.




Remove 1/3 of the dough (about 140g).
In the small part, add the sifted flour and cinnamon (1), then the cream (1).





In the biggest part, add the sifted flour and cocoa (2) and then the cream (2).





Pour the doughs into two piping bags and place in the fridge for 30 minutes.



Then pour the two doughs alternately into the cake tin (with the tube for the insert) buttered or lined with baking paper.



Make a fine line of butter along the entire length of the cake.



Bake in the preheated oven at 160°C for 1 hour and 10 minutes, check with the tip of a knife. During the cooking, prepare the punching syrup and caramel.

Punching syrup :

60g water
15g caster sugar
1 pinch of cinnamon

Bring water, cinnamon and sugar to a boil. Allow to cool.



When the cake is baked, wait 5 minutes and then unmould it on a rack. Soak it with syrup using a brush, then let it cool completely at room temperature or in the refrigerator.

Chocolate and cinnamon caramel :

50g sugar
60g liquid cream
1 egg yolk
15g butter
50g milk chocolate with 40% cacao
A pinch of cinnamon
A pinch of salt

Make a caramel with the sugar, and heat the liquid cream with the cinnamon.




Pour the cream over the caramel, stirring well.



Remove from the heat, allow to cool for a few minutes, then pour over the yolk while whisking. Pour back into a saucepan and cook like a custard at 85°C. Off the heat, add the butter, the pinch of salt and the milk chocolate, and if necessary mix to perfect the emulsion.



Put a plastic wrap on it and place it on the fridge.



When the cake is completely cold, put the caramel in a piping bag and fill the cake.



Put the cake in the freezer so you can ice it afterwards.

The icing :

300g chopped hazelnuts milk chocolate at 40% cocoa
45g grape seed oil
 
Gently melt the chocolate in a double boiler, then add the grape seed oil. Mix well and let cool.



When the cake is cold, take it out of the freezer and place it on a rack. Pour the icing over it. Let it crystallize in the refrigerator.

The whipped cream :

100g liquid cream
10g of powdered sugar

Put the liquid cream and whipped cream in the bowl of the food processor with the whisk, then whip it into whipped cream. Just before serving, add it to the cake, or with each piece after cutting. Enjoy !
