Hazelnut And Chocolate Hazelnut Cake

There’s a particular magic that happens when hazelnut meets chocolate. It’s a pairing that speaks of cozy autumn evenings, celebratory gatherings, and pure, unadulterated indulgence. This Hazelnut and Chocolate Hazelnut Cake is my homage to that perfect duo.

It’s not just a cake; it’s an experience—a moist, tender hazelnut sponge layered with a cloud-like chocolate hazelnut buttercream, all draped in a glossy dark chocolate ganache. I developed this recipe after years of testing in professional kitchens, aiming to capture that iconic flavor in a stunning, yet completely achievable, homemade dessert. The result is a show-stopper that will have everyone asking for the recipe.

• Intense, Toasted Flavor: Using finely ground, toasted hazelnuts directly in the cake batter delivers a deep, authentic nuttiness that extract alone can’t match.
• Luxurious, Balanced Texture: The cake is moist and tender, the frosting is impossibly light and fluffy, and the ganache adds a silky, rich finish—a perfect textural symphony.
• Impressively Beautiful: With its smooth frosting, glossy ganache drip, and crunchy nut garnish, this cake looks like it came from a high-end bakery, making it perfect for special occasions.
• Make-Ahead Friendly: Each component can be prepared in advance. Bake the cakes a day ahead, or freeze the frosted cake for a future celebration.
• Crowd-Pleasing Favorite: The beloved combination of hazelnut and chocolate is universally adored, ensuring this cake disappears quickly from any dessert table.
• A Rewarding Baking Project: While detailed, the steps are straightforward and teach foundational baking skills like proper creaming, crumb coating, and ganache making.

Ingredients You’ll Need

Let’s gather our ingredients—this is where quality truly shines. Using the best components you can find will elevate this cake from great to extraordinary. The star, of course, is the hazelnut.

Seek out fresh, plump nuts and take the time to toast them yourself; the flavor difference is profound. For the chocolate hazelnut spread, use a brand you love for eating by the spoonful—its flavor is the soul of the frosting.

• Hazelnuts: You’ll need whole, raw hazelnuts. We’ll toast and skin them, then grind them into a fine meal for the cake batter. This is the secret to that deep, roasted flavor.
• All-Purpose Flour: Spooned and leveled into your measuring cup to avoid a dense cake.
• Leavening Agents: A combination of baking powder and baking soda gives our nut-heavy batter the perfect lift.
• Unsalted Butter: Room temperature is non-negotiable for proper creaming in both the cake and frosting. It should give slightly when pressed.
• Granulated & Powdered Sugar: Granulated for the cake, and sifted powdered sugar for the smoothest possible buttercream.
• Eggs & Buttermilk: Both should be at room temperature to emulsify properly with the butter, creating a uniform, high-rising batter. The buttermilk adds tenderness and a slight tang.
• Chocolate Hazelnut Spread: This is the flavor powerhouse for the frosting. I prefer brands with a higher nut content and less oil separation.
• Heavy Cream: Used to loosen the frosting and create the luxurious ganache topping.
• Dark Chocolate Chips (60-70%): The higher cocoa content makes for a rich, sophisticated ganache that balances the sweetness of the cake and frosting.
• Vanilla Extract & Salt: Pure vanilla extract in both components, and a pinch of salt in the frosting to heighten all the other flavors.

Kitchen Equipment Needed

You don’t need overly specialized tools, but a few key items will make the process smoother. A stand mixer is incredibly helpful for creaming the butter and sugar to the right consistency and for whipping the frosting to airy perfection, though a sturdy hand mixer will work. A food processor is essential for grinding the hazelnuts to the correct fine texture.

Two 8-inch round cake pans, preferably light-colored metal, ensure even baking. Don’t forget parchment paper rounds for easy release, wire racks for cooling, and an offset spatula—it’s a game-changer for applying frosting smoothly.

How to Make Hazelnut and Chocolate Hazelnut Cake Recipe

Step 1: Toast, Skin, and Grind the Hazelnuts

Preheat your oven to 350°F (175°C). Spread the raw hazelnuts on a baking sheet and toast for 10-12 minutes, until fragrant and the skins are cracked. Tip from me: wrap the warm nuts in a clean kitchen towel and let them steam for a minute, then rub vigorously—most of the bitter skins will come right off.

Don’t worry about getting every last bit. Once cooled, pulse them in a food processor until they resemble fine sand. This hazelnut “flour” is what gives our cake its signature taste and texture.

Step 2: Mix the Dry Ingredients and Cream the Butter

In a medium bowl, whisk together your freshly ground hazelnuts, all-purpose flour, baking powder, baking soda, and salt. Set this aside. Now, in the bowl of your stand mixer fitted with the paddle, beat the room-temperature butter and granulated sugar on medium-high speed for a full 4-5 minutes.

Trust me, this isn’t just mixing; you’re incorporating air, which is crucial for a light cake. The mixture should become very pale and fluffy.

Step 3: Incorporate Wet Ingredients and Combine

With the mixer on low, add the room-temperature eggs one at a time, letting each fully incorporate before adding the next. Mix in the vanilla. Scrape down the bowl well.

Now, with the mixer on low, add about one-third of your dry ingredients. Once combined, pour in half of the buttermilk. Repeat, ending with the final third of dry ingredients.

Mix just until no dry streaks remain—overmixing develops gluten and leads to toughness.

Step 4: Bake and Cool Completely

Divide the batter evenly between your two prepared pans and smooth the tops. Bake for 30-35 minutes. The cakes are done when they spring back when lightly touched and a toothpick inserted in the center comes out clean.

Let them cool in the pans for 15 minutes, then turn them out onto wire racks to cool completely. Believe me, attempting to frost a warm cake is a recipe for a melted, sliding mess. Patience here is your best friend.

Step 5: Whip the Chocolate Hazelnut Frosting

While the cakes cool, make the frosting. In a clean bowl, beat the softened butter until smooth. Gradually add the sifted powdered sugar on low speed to avoid a cloud, then beat on medium-high for 3 minutes until light.

Add the chocolate hazelnut spread, heavy cream, vanilla, and a pinch of salt. Beat for another 2-3 minutes until it’s incredibly light, fluffy, and holds a peak. This frosting is so good you’ll want to eat it with a spoon.

Step 6: Assemble, Frost, and Ganache

Place one cake layer on your serving plate. Spread a generous, even layer of frosting over the top. Place the second layer on top.

Now, apply a very thin “crumb coat” of frosting over the entire cake—this seals in any loose crumbs. Chill the cake for 20 minutes. Frost the chilled cake with the remaining frosting.

For the ganache, heat the cream until steaming, pour it over the chocolate chips, let it sit for 2 minutes, then whisk until smooth. Let it cool and thicken slightly before pouring over the top of the cake, encouraging elegant drips down the sides. Garnish with the reserved chopped toasted hazelnuts.

Step back and admire your beautiful creation before slicing.

Toasting is Everything: Don’t rush toasting the hazelnuts. They should be a deep golden brown for maximum flavor. The skins are bitter, so removing most of them is worth the effort for a cleaner, sweeter nut taste. Ingredient Temperature is Critical: Using room-temperature butter, eggs, and buttermilk isn’t a suggestion—it’s the rule. Cold ingredients won’t emulsify properly, leading to a curdled-looking batter and a dense final cake. The Crumb Coat is Your Secret Weapon: That initial thin layer of frosting that gets chilled is what gives professional cakes their flawless finish. It traps all the crumbs so they don’t muddy your final, beautiful layer of frosting. Ganache Consistency: Letting the ganache cool for 5-10 minutes after mixing is crucial. If it’s too hot, it will run right off the cake. If it’s too cool, it won’t drip. You want it thick but still pourable, like warm honey. Slicing for Clean Cuts: For picture-perfect slices, dip a sharp knife in hot water, wipe it dry, and then cut. The clean, warm blade glides through the frosting and ganache without dragging.

Recipe Variations & Customizations

• Gluten-Free Adaptation: Replace the all-purpose flour with a 1:1 gluten-free baking blend. The ground hazelnuts help provide structure, making this a great candidate for gluten-free baking.

Dairy-Free Version: Use plant-based butter and buttermilk (add 1 tbsp lemon juice to 1 cup plant milk). For the frosting, use a dairy-free chocolate hazelnut spread and coconut cream instead of heavy cream. Espresso Infused: Add 1-2 tablespoons of instant espresso powder to the dry ingredients for a mocha-hazelnut twist. The coffee deepens the chocolate flavor beautifully. Fruit Accompaniment: Serve each slice with a dollop of lightly sweetened whipped cream and a handful of fresh raspberries. The tart fruit cuts through the richness perfectly. Single-Layer Simplicity: Bake the batter in a 9×13 inch pan for a simpler sheet cake. Just frost the top and drizzle with ganache for an easier, crowd-feeding option. Nut-Free Alternative: Replace the hazelnut meal in the cake with an equal amount of oat flour or more all-purpose flour, and use a chocolate frosting instead of the hazelnut buttercream.

What to Serve With This Recipe

This cake is a celebration in itself, but it can be part of a magnificent dessert spread. For a dinner party, serve it after a meal with lighter, fruit-forward elements, like a citrus salad or poached pears. A scoop of vanilla bean ice cream or a dollop of lightly sweetened whipped cream on the side provides a lovely temperature and texture contrast.

In terms of drinks, pair it with a cup of strong espresso, a glass of tawny port, or a dessert wine like a Muscat. For a larger gathering, it pairs wonderfully with other bite-sized desserts like macarons or chocolate truffles, allowing guests to sample a variety.

Storage & Make-Ahead Instructions

• Storage: Store the fully assembled cake, covered with a cake dome or loosely tented with foil, at cool room temperature for up to 2 days. For longer storage, refrigerate for up to 5 days. Let slices come to room temperature for about 30 minutes before serving for the best texture and flavor.
• Freezing: This cake freezes exceptionally well. Freeze the unfrosted, cooled cake layers wrapped tightly in plastic wrap and then foil for up to 3 months. Thaw overnight in the refrigerator. You can also freeze the fully frosted (but un-ganached) cake. Place it uncovered in the freezer until the frosting is solid, then wrap it tightly. Thaw in the refrigerator overnight, then add the ganache just before serving.
• Make-Ahead Strategy: You can bake the cake layers 1-2 days in advance. Wrap them tightly in plastic wrap once completely cool and store at room temperature. The frosting can be made up to 3 days ahead and stored in an airtight container in the refrigerator. Let it come to room temperature and re-whip briefly before using.

Frequently Asked Questions

Q: Can I use pre-ground hazelnut flour instead of grinding my own?

A: Yes, you can use store-bought hazelnut flour or meal. Use 1 1/2 cups by weight if possible, or spoon it gently into your measuring cup. Since it won’t be freshly toasted, the flavor will be milder.

You may want to toast the hazelnut flour on a baking sheet at 300°F for 5-7 minutes to revive its aroma, watching closely so it doesn’t burn.

Q: My frosting seems too soft or runny. What happened?

A: This is usually due to butter that was too warm or a very soft chocolate hazelnut spread. Pop the entire bowl of frosting into the refrigerator for 15-20 minutes, then re-whip it. If it’s still soft, you can carefully add a bit more sifted powdered sugar, a quarter cup at a time.

Q: How do I get my ganache to drip perfectly?

A: Consistency is key. After mixing the hot cream and chocolate, let it sit at room temperature, stirring occasionally, until it thickens to the viscosity of warm honey. Test a drip down the side of a bowl first.

If it’s too thick, gently re-warm it with 5-second bursts in the microwave.

Q: Can I make this cake without a stand mixer?

A: Absolutely. A sturdy electric hand mixer will work perfectly for both the cake batter and the frosting. For creaming the butter and sugar, just be prepared to mix for the full time to get proper aeration.

Q: The cake layers domed in the middle. What should I do?

A: A slight dome is normal. For perfectly flat layers, you can use bake-even strips (wet fabric strips wrapped around the pan). Or, simply use a long serrated knife to carefully slice off the domed top once the cakes are completely cool, creating a flat surface for stacking.

Q: How do I know when the cake is perfectly baked?

A: Look for three signs: the edges will pull slightly away from the pan, the top will spring back when lightly pressed, and most importantly, a toothpick inserted into the center will come out with a few moist crumbs attached, not wet batter.

Q: Is there a substitute for buttermilk?

A: Yes. For each cup of buttermilk, you can use 1 tablespoon of white vinegar or lemon juice plus enough whole milk to make 1 cup. Stir and let it sit for 5-10 minutes until it curdles slightly before using.
