A round, dark chocolate cake with a cracked top and visible hazelnuts, dusted lightly, on a cooling rack.

Ingredients

  • 200 g dark chocolate
  • 3 eggs
  • 100 g sugar
  • 120 g hazelnut flour (ground hazelnuts)
  • 100 g butter
  • 1 tsp vanilla extract
  • 1 pinch salt

Instructions

  1. 1Gently melt the chocolate and butter together in a double boiler or in the microwave, being careful not to burn it. Let it cool slightly.
  2. 2In a large bowl, whisk the eggs and sugar together until the mixture is frothy and lightened in color. Stir in the vanilla extract if using.
  3. 3Delicately fold the melted and cooled chocolate into the egg and sugar mixture.
  4. 4Gradually fold in the hazelnut flour and the pinch of salt, mixing until the batter is smooth and well combined.
  5. 5Pour the batter into a greased cake pan or one lined with parchment paper. Bake for approximately 15 to 20 minutes at 180°C (350°F). The center of the cake should remain slightly soft.
  6. 6Let it cool for a few minutes before removing from the pan. Serve warm for a molten heart or at room temperature for a firmer fudgy texture.

Tips

  • Serve with vanilla custard (crème anglaise) or orange sorbet to balance the intensity of the chocolate.
  • Use chocolate with 70% cocoa for a deeper, more intense flavor profile.
  • Buy whole hazelnuts from a local market and grind them yourself for more aroma and better value.
  • Toast the hazelnuts before grinding them to intensify their nutty flavor.

Substitutions

  • butter → coconut oil — Maintains a satisfying texture while adapting the recipe for specific dietary needs.

Frequently asked questions

Can I replace the hazelnut flour with another ingredient in this recipe?

Hazelnut flour is the star flavor of this recipe, and replacing it with another ingredient would completely change the taste and texture of the cake, so I do not recommend swapping it. However, if you are looking for other recipes, feel free to browse my blog where you will certainly find options to suit your needs.

Can the cake be frozen for longer storage?

Yes, you can freeze the cake to keep it longer. I actually recommend it, as this cake is particularly rich and a small slice is often enough. Freezing individual portions allows you to enjoy them at your own pace without worrying about the cake spoiling.

Is it possible to replace the dark chocolate with milk or white chocolate?

It is possible to replace the dark chocolate with milk or white chocolate in this recipe. However, I do not recommend it. Dark chocolate is perfectly suited for this recipe because it is less sweet and pairs particularly well with the subtle flavor of hazelnut.
