For my last masterclasses I chose to prepare this walnut financier cake because it’s easy, quick and incredibly moist! 

I added a crunchy layer made of walnut praliné, and topped it with an airy whipped ganache, with caramel flavor, which balances perfectly the bitterness of the walnut.

This is the perfect comfort cake!

This cake is made of:

  • a walnut financier cake
  • a walnut crunch
  • a whipped ganache (Caramelia chocolate of Valrhona)
  • chocolate frosting

Walnut financier cake

You can prepare the batter in advance and freeze it for a few weeks. It can as well be frozen once cooked, wrapped in a cling wrap and placed in an airtight container, for a maximum of two weeks, otherwise the taste will be affected. You can just brown the butter in advance and store it in the fridge, and melt it when needed.

Instructions
 

  • Grease the loaf pan with little melted butter (use the brush). Place it in the fridge for 10 minutes. Flour the pan and remove the excess flour.

  • Add the honey and salt to the browned butter.
  • Preheat the oven at 160°C.
  • Sift TOGETHER flour, icing sugar and baking powder.
  • Place them with the almond and walnut powders (and tonka bean if you wish) in the bowl of the stand mixer equipped with the flat beater.
  • Add the butter and honey warm mixture to the dry ingredients and mix using the flat beater (at low speed).
  • Add the egg whites (at room temperature) in 2 to 3 times, and combine (mix at low speed).
  • Pour into the loaf pan and bake for 45 minutes (check the doneness with a toothpick it has to come out clean).
  • Unmold the cake and let it cool down on a cooling rack.

Montage

Cover the cake once properly cooled with a thin layer of walnut praline crunch using an angled spatula (1). Place it in the freezer for about 5 minutes.

Meanwhile whip the ganache and pour it into a piping bag with 10mm tip. Cover the cake with around 110g of whipped ganache (2) and smooth it in order to get a nice bump (3). Let the ganache set in the freezer for 15 minutes.

Reheat the chocolate frosting (around 37°C) and dip the top of the cake in it (4).

Decorate with chopped walnuts.

Place the cake in the fridge for 10 minutes to let the frosting set.

Bon appétit!
