Chocolate Hazelnut Layer Cake

My blog is turning three this month! Three whole years!!! I’m not sure how it happened, or more specifically when it happened, but let me tell you, time flies by so quickly! Having this blog in my life means I have each and every one of you in my life and that means the world to me. Thank you for sticking around!

To celebrate this day I wanted today’s cake to be special, something that’s a bit more fancy than the everyday cakes I usually make, and one that has my name written all over it. I knew the search was over once I stumbled upon this fabulous recipe by the amazing Linda from the blog Call Me Cupcake.

Chocolate Hazelnut Layer Cake

I took one bite of this moist, fudgy piece of heaven and hoped the moment would never end. The chocolate cake base is rich and dense and has this intensely deep chocolate flavor. This is what an ultimate birthday cake should taste like.

The cake has a hazelnut filling in the center (basically Nutella), which is my favorite thing in the world right now. It’s so smooth and creamy and shiny. One thing to note is that there should be more frosting than what you see in the photos because by the time I used it for the cake, I had already eaten about 1/3 of it.

The chocolate ganache is another layer for the chocoholic, but if you really want to skip it (for whatever reason that I will never understand), you can, although I do love the appealing look of the ganache on top.

Add hazelnuts if you like. Since all the layers of the cake are fudgy and creamy, adding some crunch by using chopped hazelnuts makes it even better. You can sprinkle them either just on top of the cake or in between the layers.

Cake size. Instead of using three 6-inch pans, you can bake the cakes in two 8-inch pans. The baking time may differ slightly, so start checking them after 30 minutes.

Made of a rich chocolate cake, creamy hazelnut frosting, and chocolate ganache, this fudgy chocolate hazelnut layer cake is the ultimate treat for any celebration.

Chocolate Cake:
  • sticks (200 g) butter
  • 1/2 cup (120 ml) milk
  • cups (240 g) all-purpose flour
  • teaspoons baking soda
  • 2/3 cup (67 g) cocoa powder
  • cups (300 g) granulated sugar
  • 1/4 teaspoon salt
  • 2 large eggs
  • 2/3 cup (150 ml) sour cream
  • 1/2 cup (120 ml) hot coffee (hot water dissolved with instant coffee powder)
Chocoltate Filling
  • 75 g semisweet chocolate , coarsely chopped
  • tablespoons (35 g) butter
  • Pinch of salt
Chocolate Hazelnut Frosting:
  • sticks (150 g) butter, softened
  • 1/2 cup (113 g) cream cheese or mascarpone cheese
  • 1/2 cup (60 g) powdered sugar
  • 3/4 cup plus 2 tablespoons (250 g) Nutella or chocolate hazelnut spread
  • pinch of salt
Chocolate Glaze:
  • 75 g dark chocolate (70%), coarsely chopped
  • 3 tablespoons (45 g) butter
  • Pinch of salt
  1. To make the cake: Preheat oven to 175°C/350°F. Butter three 6-inch (15 cm) cake pans and dust them with cocoa powder.
  2. Melt the butter, add milk and set aside to cool.
  3. In a large bowl, mix together the flour, baking soda, cocoa powder, sugar and salt. Add the butter mixture, eggs and sour cream to the dry ingredients and mix until just combined. Add the hot coffee and stir until smooth (batter will be quite liquid).
  4. Divide the batter evenly between the three cake pans. Bake the cakes on the lower rack for 32-35 minutes or until a cake tester comes out clean. Let the cakes cool in their pans for 15 minutes, then invert onto a cooling rack and allow to cool completely.
  5. To make the chocolate filing: Place chocolate in a saucepan together with butter, over low heat. Stir often until everything is melted. Add a pinch of salt. Let cool to spreadable consistency – meanwhile you can prepare the frosting.
  6. To make the chocolate hazelnut frosting: In a standing mixer fitted with the paddle attachment, beat butter until pale and creamy, about 2 minutes. Add the cream cheese, powdered sugar, chocolate hazelnut spread and salt and beat until frosting is completely smooth and fluffy. If frosting feels loose, place the bowl in the fridge for a while.
  7. Assemble the cake: Place the first cake layer on a plate or cake stand. Spread with chocolate filling, then pipe or spread a layer of frosting on top (save some frosting for the second layer as well). Don’t pipe or spread all the way out to the edge as the weight of the cake will make it spread.
  8. Place the second layer on top of the first layer. Spread second layer with chocolate filling, then pipe or spread a layer of frosting on top. Put the third layer on top. Put the cake in the fridge to stabilize it while you prepare the dark chocolate glaze.
  9. To make the chocolate glaze: Coarsely chop the dark chocolate and place it in a saucepan together with butter, over low heat. Stir often until melted. Add a pinch of salt. Let cool slightly but make sure it doesn’t thicken too much, it should still be liquid. Pour the glaze over the cake and quickly spread it over the edges of the cake to make it run down the sides.
  10. Keep cake in the fridge but serve it in room temperature.

    Hi Shiran, can I ask you a question? Well, why are your recipes so nice? 🙂 It is so easy but it looks like heaven ?! Well I have a question please… Can I use nuttela instead of the chocolate hazelnut frosting , instead of the chocolate glaze can I use chocolate ganache and is there any way in which I can use less butter? Well now I am a fan of your recipes … Thanks a lot! ?

      I think that using Nutella instead of the frosting will be a bit heavy with the chocolate glaze. You can use another frosting that you like. You can use chocolate ganache, but its texture should be quite thick.

    I am planning to substitute the 200g with 3/4 vegetable oil. Can I?

      Hi Simone, when a cake or frosting recipe calls for butter, using oil instead can affect the flavor and texture dramatically. Sometimes it will work, but I can’t say this for sure without testing.

    HI I’m asking my husband to make this for
    My birthday but I just have one concern. I’m worried adding hot coffee to the batter would cause the sour cream to separate. Is it just a mater of adding it last?

      Hi Hope, you should add the water after all the other ingredients are mixed, so it will be ok. Happy birthday!

    Hi Shiran! Thanks a lot for the amazing recipe. I am about to go for it but we don’t have sour cream were I live. What subtitute would you recommend so that I can get as close as possible to your recipe? Thanks a lot, Sophia

      Hi Sophi, you can use buttermilk, and if you can’t find it, use plain yogurt. It would taste slightly different but still delicious.

    I made this today, substituting the coffee for plain old water. Worked fine (o:
    The cake is a little heavy with all that cream, but it is lovely and tasty and if any one leaves that table feeling hungry, it’s definitely their own fault (o:

    How would the baking time change if I make cupcakes instead?

      Hi Tria. For cupcakes the baking time would be 15-20 minutes.
