“Infinitely hazelnut” cake infinitely delicious, from the great chef “Pierre Hermé”.

Method

Praliné- feuilletine :

• 1)

  In a bowl, combine the melted milk chocolate, the hazelnut praliné, the hazelnut paste, the cooled melted butter, the coarsely chopped hazelnuts and finally the feuilletine (crispy crêpe dentelle). Mix everything until a homogeneous dough is obtained, fill a circle 1.5 cm high with this mixture, then put it in the freezer for about 30 minutes.

  

  Cut it into 1.5 cm cubes.  Put everything back in the freezer.

  

Cake batter :

• 1)

  Roast the hazelnuts for 15 minutes in an oven preheated to 160C, blend to obtain a powder.
  During this time, make the brown butter, filter and let it cool.
  In a bowl on the electric mixer fitted with the paddle attachment, pour the hazelnut powder, fleur de sel, icing sugar, 100 g of brown sugar, and the previously beaten eggs.  Mix all of these ingredients well until you get a homogeneous mixture.  Then add the flour, cornstarch and warm brown butter.  Mix until everything is completely incorporated and homogenized. Set aside the time to whisk the egg whites with the remaining 20g of sugar.  It is important that the whites are not too firm to facilitate their incorporation into the previous mixture (a light peaks form is enough, a texture of shaving foam).
  Using the spatula, and gently fold in the egg whites so as not to drop themn until Incorpora. Finally add the roasted and coarsely chopped hazelnuts.

   

  
  

  Fill 1/3 of a buttered mold with the cake batter, add a few frozen praliné-feuilletine cubes, cover them with the cake batter, add once more the frozen praliné-feuilletine cubes then cover one last time with the cake batter.

  
  

  Bake for 10 minutes at 180C followed by 40 minutes at 170C, or until the cake is cooked and golden.

Syrup :

  Meanwhile, make the syrup.
  In a saucepan, put the caster sugar and the water, bring to the boil, wait a few seconds, the sugar must be completely dissolved, before adding everything to the hazelnut paste, mix using a hand blender to have a   homogenize liquid.

  Take the cake out of the oven, let it cool down to be able to unmold it and soak it with syrup using a brush.
  Soak the cake while it is still hot with the hot syrup, both must have the same temperature.

Dulcey chocolate icing :
