- 150 grams dark chocolate – Melted dark chocolate adds a luxurious richness to the cake.
- 150 grams unsalted butter – Gives the cake a buttery flavor and soft texture.
Hazelnut Ganache Ingredients
- 300 grams dark chocolate – Rich, smooth dark chocolate forms the base of the ganache.
- 300 grams double cream – Cream helps make the ganache smooth and glossy.
- Chopped hazelnuts – Toasted hazelnuts add crunch and enhance the nutty flavor.
Nutella Buttercream Ingredients
- 400 grams unsalted butter – The butter serves as the base of the buttercream, ensuring a smooth consistency.
- 750 grams icing sugar – Icing sugar gives the buttercream its sweetness and fluffy texture.
- 50 grams cocoa powder – Adds extra chocolate flavor to the buttercream.
- 150 grams Nutella – The star of the buttercream, giving it a rich, nutty flavor.

Decorations

Required Kitchen Tools
To create this mouthwatering Chocolate Hazelnut Cake, having the right tools will make the process much easier and enjoyable. Here are the essential kitchen tools you’ll need:
- Electric Mixer (Hand or Stand): You’ll need a mixer to beat the buttercream and cake batter until smooth and fluffy. A stand mixer can save you time, but a hand mixer will work just as well.
- Cake Pans: Two 8-inch round cake pans will work best for this recipe. Make sure to grease and line them with parchment paper to prevent the cake from sticking.
- Double Boiler or Microwave: You’ll need a method for melting the dark chocolate for both the cake and the ganache. A double boiler is ideal, but a microwave works just as well if you’re careful not to burn the chocolate.
- Piping Bags: Use piping bags to apply the Nutella buttercream in neat layers and to decorate the cake with Nutella drizzles.
- Offset Spatula: A spatula is a great tool to smooth out the buttercream and ganache on the cake for a professional-looking finish.
- Cooling Rack: Let your cakes cool completely on a cooling rack before assembling the cake to ensure the layers don’t become soggy.
Step-by-Step Preparation of Your Chocolate Hazelnut Cake
Now that we have our ingredients and tools ready, let’s dive into the baking process. This part will guide you through making the cake itself, preparing the hazelnut ganache, and whipping up the Nutella buttercream. The process is broken down into clear steps, so whether you’re a beginner or an experienced baker, you’ll be able to follow along easily.
Step 1: Making the Chocolate Cake
The foundation of this Chocolate Hazelnut Cake is a rich, moist chocolate cake. Follow these steps to ensure your cake layers turn out perfectly:
Mixing the Dry Ingredients
- Preheat your oven to 180°C (350°F). Grease and line your 8-inch round cake pans with parchment paper, ensuring the edges are covered.
- In a medium bowl, sift together plain flour, cocoa powder, and baking powder. This helps to remove any lumps and ensures the ingredients are well combined. Set aside.
Preparing the Wet Ingredients
- In a separate, larger mixing bowl, cream together unsalted butter and light brown sugar using an electric mixer. Beat on medium speed for about 3-4 minutes until light and fluffy.
- Add the eggs, one at a time, mixing well after each addition. Make sure each egg is fully incorporated before adding the next.
- Stir in the espresso and buttermilk. The espresso will deepen the chocolate flavor, while the buttermilk adds moisture.
Combining the Wet and Dry Ingredients
- Gradually add the dry ingredients into the wet ingredients, mixing on low speed. Alternate adding the flour mixture with the melted dark chocolate. Start and finish with the dry ingredients to ensure a smooth batter.
- Scrape down the sides of the bowl and mix for an additional 30 seconds to ensure everything is fully combined.
Baking the Cake Layers
- Divide the batter evenly between the two prepared cake pans.
- Bake for 25-30 minutes, or until a toothpick inserted into the center of the cakes comes out clean. Avoid opening the oven door too frequently to prevent the cakes from sinking.
- Once done, remove from the oven and let the cakes cool in the pans for 10 minutes. Then, transfer them to a cooling rack to cool completely.
Step 2: Preparing the Hazelnut Ganache
While the cake layers are cooling, you can prepare the hazelnut ganache to add a rich, glossy layer between the cake and the Nutella buttercream.
Making the Ganache
- Place dark chocolate in a heatproof bowl.
- Heat the double cream in a saucepan over medium heat until it begins to simmer. Do not let it boil. Once heated, pour the cream over the chocolate.
- Let the mixture sit for about 1-2 minutes to melt the chocolate, then gently stir until smooth and glossy.
- Once the ganache is smooth, stir in the chopped hazelnuts and let it cool to room temperature.
Step 3: Whipping Up the Nutella Buttercream
This Nutella buttercream is the star of the cake, giving it that creamy, hazelnut-chocolate flavor that everyone loves. Follow these steps to create the perfect buttercream:
Preparing the Buttercream Base
- In a large bowl, beat the unsalted butter on medium speed for about 3-4 minutes until it’s light and fluffy.
- Gradually add the icing sugar and cocoa powder, mixing well after each addition. Beat on low speed to prevent a sugar cloud, then increase the speed to medium and continue for another 3-4 minutes.
- Add the Nutella and beat until the mixture is smooth and creamy.
Adjusting the Consistency
If your buttercream is too thick, add a few drops of milk to reach your desired consistency. If it’s too thin, add a little more powdered sugar to thicken it.
Once your cake layers have cooled, your ganache is ready, and your buttercream is smooth, you’re all set to start assembling your Chocolate Hazelnut Cake!
Assembling and Decorating Your Chocolate Hazelnut Cake
Now comes the fun part: assembling and decorating your Chocolate Hazelnut Cake! You’ve made the rich chocolate cake layers, prepared the hazelnut ganache, and whipped up the Nutella buttercream. Now it’s time to put everything together into a show-stopping dessert that’s as beautiful as it is delicious. Follow these steps to create a perfectly layered cake that will impress your guests and satisfy your sweet tooth.
Step 4: Assembling the Cake Layers
- Level the Cake Layers:
Once your cake layers are completely cool, use a serrated knife to level the tops of the cakes, if needed. This will ensure your cake layers are even and that the final cake has a flat, professional-looking surface. - First Layer of Cake:
Place one of the cake layers onto a cake stand or a large serving plate. Spread a generous amount of Nutella buttercream on top of the first layer. Use an offset spatula to spread it evenly to the edges. - Add the Hazelnut Ganache:
Next, spoon the hazelnut ganache over the buttercream layer, spreading it evenly to cover the entire surface. Don’t worry if it spills slightly over the edges; this will create a beautiful effect when you add the final layer. - Add the Second Cake Layer:
Place the second cake layer on top of the ganache, pressing down gently to ensure it sticks. - Final Buttercream Layer:
Use the remaining Nutella buttercream to cover the top and sides of the entire cake. Use a spatula to smooth out the sides, creating a sleek, even finish. Don’t worry if it’s not perfect—this rustic look adds charm and texture to the cake.
Step 5: Decorating the Cake
Now that your cake is assembled, it’s time to decorate and add those finishing touches that will make your cake look and taste even more indulgent.
- Nutella Drizzle:
Heat the remaining 2 tablespoons of Nutella in the microwave for 10-15 seconds until it’s pourable. Drizzle the warm Nutella over the top of the cake, allowing it to flow over the edges for a decadent look. You can use a spoon to create a swirl effect for a more artistic finish. - Ferrero Rocher:
For a touch of luxury, arrange Ferrero Rocher chocolates around the edges of the cake or in the center. These chocolates not only look beautiful, but they also bring that signature hazelnut-chocolate crunch. - Chopped Hazelnuts:
Finally, sprinkle the chopped hazelnuts over the top of the cake. This will add a lovely texture and enhance the nutty flavor of the cake. You can also lightly toast the hazelnuts for extra flavor before sprinkling them on top.
Step 6: Let the Cake Set
Once decorated, let the cake sit for at least 30 minutes to allow the buttercream and ganache to set. This will also give the flavors a chance to meld together, making every bite even more delicious. If you want a firmer texture for the ganache, you can refrigerate the cake for about an hour before serving.
Serving and Storing Your Chocolate Hazelnut Cake
Now that your Chocolate Hazelnut Cake is beautifully assembled and decorated, it’s time to dive in! This rich, indulgent dessert is perfect for any occasion, whether it’s a birthday, a holiday gathering, or just a treat for yourself. But before you serve, let’s go over the best ways to store and preserve your cake so you can enjoy it for days to come.
Step 7: Serving Your Chocolate Hazelnut Cake
- Slice with Care:
When slicing your cake, use a serrated knife to ensure clean, smooth cuts. A warm knife (dipped in hot water and wiped dry) will make cutting easier and ensure that each slice is neat and clean. You’ll want to cut each slice through the cake, ganache, and buttercream to get the perfect combination of textures in each bite. - Pair with a Beverage:
This Chocolate Hazelnut Cake pairs wonderfully with a cup of coffee, a glass of dessert wine, or a rich hot chocolate. For a more indulgent experience, serve each slice with a dollop of whipped cream or a scoop of vanilla ice cream on the side. - Perfect for Special Occasions:
With its rich chocolate flavor and hazelnut finish, this cake is ideal for celebrations. It’s a showstopper that will steal the spotlight at birthdays, holidays, and gatherings with friends and family. Your guests will love the combination of textures—from the moist cake layers to the creamy Nutella buttercream and crunchy hazelnuts.
Step 8: Storage Instructions
- How to Keep the Cake Fresh:
If you have any leftover cake (which is rare!), you can store it in an airtight container at room temperature for up to 3 days. Be sure to place the container in a cool, dry place, away from direct sunlight or heat sources. This will help preserve the moisture and texture of the cake. - Refrigeration:
If you live in a warmer climate or want to keep the cake for a longer period, you can refrigerate it. Just make sure the cake is covered well to prevent it from drying out. Stored in the fridge, the cake will stay fresh for up to 5 days. Let it sit at room temperature for about 30 minutes before serving for the best flavor and texture. - Freezing the Cake:
If you’d like to keep this cake for even longer, you can freeze it! To freeze, first slice the cake and wrap each slice tightly in plastic wrap or aluminum foil. Place the wrapped slices in a freezer-safe bag or container. The cake can be frozen for up to 1 month. When ready to enjoy, let the slices thaw at room temperature for a few hours, or warm them slightly in the oven to regain that freshly baked taste.
