Method
 

Step-by-Step Instructions
  1. Preheat your oven to 170°C (340°F) and line two round cake pans with baking paper.
  2. Spread the toasted hazelnuts on a baking tray and roast for about 20 minutes until golden and fragrant.
  3. In a saucepan, whisk together the corn starch, caster sugar, and fine salt. Gradually add the warm whole milk while continuously whisking. Cook over medium heat until thickened, about 5-7 minutes, then stir in butter and dark cooking chocolate until smooth.
  4. In a small saucepan, combine sugar and water over medium heat until dissolved, and boil gently until golden caramel. Stir in toasted hazelnuts and spread on a baking sheet to cool.
  5. Process half of the remaining hazelnuts into fine crumbs. In a bowl, beat the egg whites until stiff peaks form, then fold in the hazelnut crumbs and sugar. Spoon into pans and bake for 15 minutes until lightly golden.
  6. Cool the dacquoise layers completely, then layer with chocolate pastry cream in a springform pan, reserving some pastry cream for the sides.
  7. Prepare glazes by blending powdered sugar with melted butter, split it and mix one portion with cocoa powder.
  8. Pour the vanilla glaze over the top of your assembled cake, chill for at least 4 hours and coat the sides with reserved pastry cream and sprinkle with hazelnut crumbs before serving.
