Why This Recipe Works

This hazelnut chocolate cake strikes the perfect balance: rich cocoa depth, plush crumb, and the irresistible crunch of roasted hazelnuts. Toasting the hazelnuts brings out their natural oils, intensifying both flavor and aroma. The cake uses buttermilk for a melt-in-your-mouth texture and is layered with a chocolate-hazelnut ganache that’s easy to spread but sets with a beautiful sheen. It’s just fancy enough for celebrations, yet approachable for confident beginners—no complicated equipment or fussing with sugar syrups.

Hazelnut and dark chocolate are a classic pairing, inspired by European desserts like gianduja and Nutella-filled confections, but this version amps up the homemade comfort. The ganache isn’t just delicious; it makes decorating simple and forgiving. Plus, this recipe lets you adapt for dietary preferences or add a fun seasonal twist.

Ingredients You’ll Need

• For the Cake:
  • 1 cup (120g) hazelnuts, toasted and chopped
  • 2 cups (250g) all-purpose flour
  • 3/4 cup (75g) unsweetened cocoa powder
  • 1 and 3/4 cups (350g) granulated sugar
  • 1 and 1/2 teaspoons baking powder
  • 1 and 1/2 teaspoons baking soda
  • 1/2 teaspoon fine sea salt
  • 1/2 cup (120ml) vegetable oil
  • 2 large eggs, room temperature
  • 1 cup (240ml) buttermilk, room temperature
  • 1 cup (240ml) freshly brewed hot coffee
  • 2 teaspoons vanilla extract
• For the Chocolate-Hazelnut Ganache:
  • 8 ounces (225g) bittersweet or semisweet chocolate, chopped
  • 1/2 cup (120ml) heavy cream
  • 1/2 cup (150g) chocolate-hazelnut spread (such as Nutella)
  • 1 tablespoon unsalted butter
  • Pinch of fine sea salt
• Optional Decorations:
  • Whole toasted hazelnuts
  • Chocolate curls or shavings
  • Powdered sugar, for dusting

Step-by-Step Cooking Instructions

1. 1. Prep the pans and hazelnuts: Preheat your oven to 350°F (175°C). Grease two 8-inch round cake pans and line the bottoms with parchment paper. Spread hazelnuts in a single layer on a baking sheet and toast for 8–10 minutes, or until fragrant and golden brown. When cooled, chop coarsely, reserving a handful for garnish.
   2. Mix dry ingredients: In a large bowl, whisk together flour, cocoa powder, sugar, baking powder, baking soda, and salt until fully blended and no clumps remain.
   3. Combine wet ingredients: In another bowl, whisk eggs, buttermilk, vegetable oil, and vanilla until smooth. Pour the wet mixture into the dry ingredients and whisk until almost combined.
   4. Add hot coffee and hazelnuts: Slowly pour in the hot coffee while whisking gently (this helps bloom the cocoa and intensifies the flavor). Mix until the batter is smooth and glossy. Fold in the chopped toasted hazelnuts.
   5. Bake the cakes: Divide batter evenly between the prepared pans. Smooth tops with a spatula and bake for 32–38 minutes, or until a skewer inserted in the center comes out with a few moist crumbs. Cool cakes in pans for 10 minutes, then invert onto a wire rack and remove parchment. Let cool completely before assembling.

1. Prepare the ganache: Place chopped chocolate in a medium heatproof bowl. In a small saucepan, heat cream just until steaming but not boiling. Pour hot cream over the chocolate and let sit 2 minutes to melt. Add hazelnut spread, butter, and a pinch of salt. Stir until silky and smooth. Let cool until thick but spreadable, about 30 minutes.
2. Assemble the cake: Place one cooled cake layer on a serving plate. Spread about one-third of the ganache evenly over the surface. Top with the second layer and use remaining ganache to cover the top and sides. Swirl decoratively or smooth for a glossy finish.
3. Decorate and serve: Press reserved hazelnuts and chocolate curls along the edge or center. Finish with a dusting of powdered sugar for extra flair.

Recipe Variations & Dietary Modifications

• Keto/Low-Carb Version: Substitute almond flour (use 2 cups) for all-purpose flour, a low-carb sweetener like erythritol for sugar, and use unsweetened chocolate plus extra hazelnut spread for the ganache. Eliminate the buttermilk and use heavy cream instead. Baking time may reduce by 3-5 minutes—check early.
• Vegan Version: Swap eggs for 2 flax eggs (2 tablespoons flaxseed meal + 6 tablespoons water, mixed and set for 5 minutes). Use unsweetened oat milk with a touch of lemon juice instead of buttermilk. Opt for vegan chocolate and coconut cream for the ganache. Bake as directed.
• Gluten-Free Version: Replace all-purpose flour with a 1-to-1 gluten-free baking blend. Ensure your baking powder and vanilla are gluten-free certified.
• Mild Version: For a less intense cocoa flavor, use only 1/2 cup cocoa and substitute the remainder with extra flour.
• Upgrade: Mix in orange zest with the batter for a chocolate-orange-hazelnut twist, or stir a splash of Frangelico liqueur into the ganache for a grown-up finish!

Adjusting these variations may slightly change the texture and flavor—but all remain deliciously satisfying!

Serving Suggestions & Pairings

For a simple yet stunning presentation, garnish your hazelnut chocolate cake with a scatter of whole roasted hazelnuts and a flourish of chocolate curls. The glossy ganache naturally creates a “bakery-worthy” look—no need for piping skills or fancy decor.

Pair slices of this cake with a scoop of vanilla bean ice cream or a dollop of freshly whipped cream. For an elegant gathering, serve alongside fresh raspberries or poached pears to balance the richness with a burst of fruit acidity. Coffee, espresso, or a glass of dessert wine like Frangelico or ruby port all complement the nutty-chocolate profile beautifully.

Storage & Meal Prep Tips

To keep your hazelnut chocolate cake as fresh as day one, store leftover slices in an airtight container at room temperature for up to 2 days, or in the refrigerator for up to 5 days. Make sure the container is well-sealed to prevent the cake from drying out.

The ganache frosting holds up well in the fridge and prevents the cake from getting stale. You can also freeze individual (well-wrapped) slices for 1–2 months—thaw overnight in the fridge, then let come to room temperature before enjoying. For best flavor and texture, slice and decorate on the day you plan to serve.

Want to get ahead? You can bake the cake layers up to 2 days in advance, wrap tightly in plastic, and refrigerate. Ganache can be made a day ahead and reheated gently to softened consistency when ready to assemble.
