I first created this Chocolate Hazelnut Cake for my daughter's birthday, and it's become our most requested celebration cake ever since. The combination of rich chocolate layers, creamy Nutella buttercream, and crunchy hazelnuts creates pure magic. Every time I make it, the kitchen fills with the most incredible chocolate-hazelnut aroma that brings everyone running.
Why This Cake Brings Joy
What I love most about this cake is how it makes every occasion feel special. That perfect balance of chocolate and hazelnut in every bite, the way the buttercream melts on your tongue - it's like a fancy bakery cake but even better because it's made with love at home.
Perfect For Any Celebration
Whether it's a birthday, holiday gathering, or just because, this cake never fails to impress. I love watching people's faces light up when they see it, and those first bites always bring smiles. Plus it stays beautifully moist making it perfect for making ahead.
Let's Gather Our Ingredients
- Dutch Cocoa: It makes the richest chocolate cake
- Good Oil: Keeps everything perfectly moist
- Fresh Dairy: Sour cream milk and cream for richness
- Hot Coffee: Trust me it makes the chocolate shine
- Nutella: Our star ingredient
- Fresh Hazelnuts: For that perfect crunch
- Powdered Sugar: Makes the silkiest frosting
Making It Work For You
Sometimes I'll use Greek yogurt instead of sour cream, or hot water if I'm out of coffee. The recipe is wonderfully forgiving. Adding some chopped Ferrero Rocher candies to the filling? Pure genius my friends discovered by happy accident.
All About That Cocoa
While I love Dutch-processed cocoa for its deep color and flavor, any good cocoa powder works beautifully here. The key is using what you have and loving the process. Each version brings its own special charm.

Tools Of Love
A few good tools make this cake pure joy to create. My offset spatula is like an old friend helping smooth that buttercream perfectly. A revolving cake stand makes decorating feel like dancing. But don't worry if you don't have everything - love is the most important ingredient.
Creating The Base
When mixing your batter, watch for that moment of magic when everything comes together. Adding the hot coffee at the end creates this incredibly silky texture. The batter will be thin - that's exactly what we want for the moistest cake.
Baking With Care
Dividing the batter evenly between pans is like creating twins - you want them to match. I always give my pans a gentle tap on the counter to remove air bubbles. That toothpick test never lies when checking for doneness.
Filling Dreams
Creating that Nutella filling is pure joy. Watch how it transforms when you whip it with cream, becoming light and fluffy. Those roasted hazelnuts folded in add such wonderful texture. Sometimes I make extra just because.
Buttercream Magic
The buttercream is where patience pays off. Start with soft butter, add your Nutella, then slowly incorporate the powdered sugar. When it all comes together, it's like clouds of chocolate hazelnut heaven.
Building Beauty
Assembly is like building a delicious tower of joy. That frosting dam around the edge keeps everything neat while the filling stays perfectly in place. Each layer adds to the anticipation of that first slice.

The Final Touch
Drizzling warm Nutella over the top creates beautiful patterns that make everyone say 'wow.' Those scattered hazelnuts aren't just pretty - they hint at the deliciousness waiting inside.
My Best Tips
Room temperature ingredients are your friends here. Take time to sift that cocoa powder - no one wants chocolate lumps in their cake. And please, let those layers cool completely before frosting. Patience creates perfection.
Keeping It Fresh
This cake stays beautiful at room temperature for a day, though it rarely lasts that long in my house. If you need longer storage, the fridge works fine just let slices come to room temperature before serving.
Freezer Friends
Sometimes I'll freeze individual slices wrapped well they're like having a piece of celebration ready whenever you need it. The whole cake freezes beautifully too just take your time thawing.
Planning Ahead
I often make components ahead when planning a party. The cake layers, filling, and frosting all wait patiently in the fridge until you're ready to create your masterpiece.
Perfect Partners
A cup of strong coffee or scoop of vanilla ice cream makes this cake even more special. Something about those combinations just works like they were meant to be together.

Spreading Joy
This cake has starred at countless celebrations in our home. It's amazing how a simple dessert can bring people together creating moments and memories around the table.
Make It Your Own
Sometimes I'll add extra decorations like chocolate shavings or even edible gold leaf for extra special occasions. The basic recipe is just your starting point let your creativity shine.
For Nutella Lovers
If you love Nutella, this cake is your dream come true. That chocolate hazelnut flavor shines in every layer making each bite pure bliss. It's indulgent in the best possible way.
Perfect Pairings
A glass of hazelnut liqueur alongside makes this dessert feel extra special. Even a simple espresso brings out all those wonderful flavors. It's about creating moments of joy.
You Can Do This
Don't let the steps intimidate you. Take it one layer at a time one component at a time. Before you know it you'll have created something beautiful and delicious.

Frequently Asked Questions
- → Can I make this cake in advance?
Yes, you can make this cake one day ahead and store at room temperature. After that, refrigerate for up to 3 days. Cover cut sides with plastic wrap to keep the filling fresh.
- → Why use hot coffee in the cake batter?
Hot coffee enhances the chocolate flavor and creates a richer, more complex taste. You can substitute hot water if you prefer, but coffee won't make the cake taste like coffee.
- → Can I use regular cocoa powder instead of Dutch-processed?
While Dutch-processed cocoa is preferred for its deeper color and flavor, regular cocoa powder will work. The cake might be slightly lighter in color and less intense in flavor.
- → Why do the ingredients need to be room temperature?
Room temperature ingredients blend more evenly and create a smoother batter, resulting in a more uniform texture in the finished cake.
- → Can I freeze this cake?
Yes, you can freeze the unfrosted cake layers for up to 3 months. Thaw completely before filling and frosting. The assembled cake can be frozen for up to 1 month.
