Flourless Chocolate Hazelnut Fudge Cake

A rich, gooey, and naturally gluten-free flourless chocolate fudge cake, loaded with toasted hazelnuts and topped with dark chocolate chunks. Perfect for chocolate lovers and special occasions.

Ingredients

Scale
  • 1/2 cup unsalted butter
  • 6 oz dark chocolate, chopped
  • 2/3 cup granulated sugar
  • 1/4 cup brown sugar
  • 3 large eggs
  • 1/4 cup unsweetened cocoa powder
  • 1/2 tsp vanilla extract
  • 1/4 tsp salt
  • 1/2 cup chopped toasted hazelnuts (plus extra for topping)
  • 1/4 cup dark chocolate chunks for topping

Instructions

  1. Preheat oven to 350°F (175°C). Grease and line an 8-inch round cake pan with parchment paper.
  2. In a heatproof bowl, melt butter and dark chocolate together using a microwave or double boiler. Stir until smooth and glossy. Let cool slightly.
  3. In a mixing bowl, whisk together eggs, granulated sugar, brown sugar, vanilla extract, and salt until pale and thick, about 2–3 minutes.
  4. Fold in the melted chocolate mixture until fully combined.
  5. Sift in cocoa powder and mix until smooth.
  6. Fold in chopped toasted hazelnuts.
  7. Pour the batter into the prepared cake pan and smooth the top.
  8. Sprinkle with additional chopped hazelnuts and dark chocolate chunks.
  9. Bake for 22–25 minutes, until edges are set and center is just slightly jiggly.
  10. Cool completely before slicing. Serve as is or with coffee or vanilla ice cream.

Notes

  • Use high-quality dark chocolate for best flavor.
  • The center should remain slightly gooey for a true fudge texture.
  • Can be made ahead and stored in the fridge for up to 3 days.
  • Serve with whipped cream or berries for an elegant touch.
