My new guilty pleasure: a rich, fudgy chocolate cake with a delicious hazelnut flavor, and best of all, it's flourless, which I've christened Chocanut. This cake is truly excellent, try it soon! The idea came to me after making the delicious Piedmontese hazelnut cake : I thought, why not add a middle layer of caramel or chocolate? I ended up incorporating it into the batter, and the result lived up to my expectations! Ground hazelnuts, whipped egg whites, and a chocolate caramel made like in millionaire's shortbread : absolutely divine! Go ahead and try it, you won't regret it.
Grind the hazelnuts into a powder in your food processor.
Mix them with the egg yolks.
Gently fold the beaten egg whites into the hazelnut mixture using a wooden or silicone spatula.Step 2: Prepare the chocolate caramel

Mix the cornstarch with the water and set aside.
Melt the sugar dry in a saucepan (do not stir, just shake).
When it is amber, remove from the heat, add the butter and mix.
Heat the cream and pour it in little by little while stirring (be careful of splashes).
Return to low heat.
Add the diluted cornflour, that's what gives it the smooth texture.
Let it simmer for a few minutes while stirring (it should coat the spoon).
Add the salt, mix.

Remove from heat, add the 4 tablespoons of cocoa powder and mix again.
Pour the caramel over the hazelnut mixture and mix well.
Pour the batter into a mold (I use a 25cm round silicone mold)
Enjoy!
