Ingredients
  

Main Ingredients
  • 1 cup Toasted Hazelnuts Use roasted hazelnuts for enhanced flavor.
  • 8 ounces Dark Chocolate (Chopped) Can substitute with milk chocolate for a sweeter taste.
  • 4 tablespoons Unsalted Butter
  • 3 Large Eggs (Separated) Ensure eggs are at room temperature.
  • 1/4 cup Granulated Sugar
  • 1/2 teaspoon Vanilla Extract
  • 1 pinch Salt
  • 1/2 cup Heavy Cream

Method
 

Preparation
  1. Preheat your oven to 350°F (175°C). Grease the bottom and sides of a round cake pan with butter and place a circle of parchment paper at the bottom.
  2. Add the toasted hazelnuts to a food processor and pulse until finely ground.
  3. In a small pot, bring water to a gentle simmer. Melt the dark chocolate and butter over it, creating a double boiler.
  4. In a separate bowl, whisk together the egg yolks, granulated sugar, and vanilla extract until pale and thick.
  5. Gradually mix the warm chocolate mixture into the egg yolks, whisking continuously.
  6. Gently fold in the ground hazelnuts.
  7. In another bowl, beat the egg whites with a pinch of salt until stiff peaks form. Carefully incorporate them into the chocolate mixture to maintain an airy texture.
  8. Whip the heavy cream until soft peaks form, then gently fold it into the batter.
Baking
  1. Pour the batter into the prepared cake pan and smooth the top.
  2. Bake for approximately 25 minutes until set.
Serving
  1. Allow the cake to cool slightly before inverting onto a serving plate.
  2. Dust with cocoa powder or powdered sugar, and serve with whipped cream or vanilla ice cream.

Notes

Store any leftovers in an airtight container in the refrigerator for up to four days. Allow to come to room temperature before serving again for best flavor.
