Ingredients
Essential Ingredients for the Cake
- 1 ¾ cups all-purpose flour
- 1 ½ cups granulated sugar
- ¾ cup unsweetened cocoa powder
- 1 ½ teaspoons baking powder
- 1 ½ teaspoons baking soda
- 1 teaspoon salt
- 2 large eggs
- 1 cup whole milk
- ½ cup vegetable oil
- 2 teaspoons vanilla extract
- 1 cup boiling water
- 1 cup finely ground hazelnuts (optional for added texture)
For this cake, start with the basics. The all-purpose flour gives structure, while sugar adds sweetness. Cocoa powder brings rich chocolate flavor. Baking powder and baking soda help the cake rise. The eggs bind it together, and milk keeps it moist.
Ingredients for the Frosting
- 1 ½ cups heavy cream
- ½ cup powdered sugar
- ½ cup chocolate hazelnut spread
For the frosting, heavy cream is key for creaminess. Powdered sugar sweetens it up. The chocolate hazelnut spread adds a rich, nutty flavor that pairs perfectly with the cake.
Optional Additions
- 1 cup finely ground hazelnuts
- 2 teaspoons vanilla extract
You can add ground hazelnuts to the cake batter for extra crunch and flavor. A splash of vanilla in the frosting enhances the taste, making it even more delicious. These optional ingredients can elevate your cake to a whole new level.

Step-by-Step Instructions
Preparing the Cake Batter
1. Preheat your oven to 350°F (175°C). Grease two 9-inch round cake pans. Dust them lightly with flour. This keeps the cakes from sticking.
2. In a large bowl, sift together the all-purpose flour, granulated sugar, unsweetened cocoa powder, baking powder, baking soda, and salt. Use a whisk to mix until no lumps remain.
3. Add in the large eggs, whole milk, vegetable oil, and vanilla extract. Beat the mixture on medium speed with an electric mixer for about 2 minutes. You want a smooth batter.
4. Carefully stir in the boiling water. The batter will be thin, and that is fine! If you like, fold in the finely ground hazelnuts now for extra flavor.
Baking the Cake
1. Divide the batter evenly between the prepared cake pans. Make sure both pans have the same amount.
2. Place the pans in the oven and bake for 30-35 minutes. Check for doneness by inserting a toothpick into the center. It should come out clean.
Making the Frosting and Assembling the Cake
1. In a medium bowl, whip the heavy cream until it starts to thicken. Add the powdered sugar and vanilla extract. Continue to whip until stiff peaks form.
2. On a serving plate, place one cooled cake layer. Spread a generous layer of chocolate hazelnut spread on top. Then, dollop some whipped frosting over it.
3. Carefully set the second cake layer on top. Use the remaining whipped frosting to cover the entire cake for a smooth finish.
4. For a final touch, decorate the top with chopped hazelnuts or chocolate shavings. This adds crunch and makes it look stunning.
Tips & Tricks
Baking Tips for Success
To ensure a moist cake texture, always measure your flour correctly. Use a spoon to fill the measuring cup and level it off with a knife. This helps avoid too much flour, which can dry out your cake. Adding boiling water to the batter also keeps it moist. The heat activates the cocoa and helps create a rich flavor.
For proper oven techniques, preheat your oven to 350°F (175°C) before baking. This step ensures even cooking. Avoid opening the oven door too early. It can cause the cake to sink. Check for doneness by inserting a toothpick into the center. If it comes out clean, your cake is ready.
Frosting Tips
To achieve the perfect whipped frosting consistency, start with cold heavy cream. Cold cream whips up better and gives a fluffier texture. Whip it until you see stiff peaks. This means the frosting will hold its shape well when spread.
When spreading frosting smoothly, use an offset spatula. Start from the center and work your way outwards. For a nice finish, dip the spatula in hot water before smoothing. Wipe it dry and repeat as needed. This technique helps create a clean and polished look.
Presentation and Serving Suggestions
For decorative ideas, sprinkle chopped hazelnuts or chocolate shavings on top. This adds texture and makes your cake look fancy. You can also add fresh berries around the base for color.
For ideal pairings, serve slices on elegant plates with a side of fresh berries. A dusting of cocoa powder adds a nice touch too. This makes the dessert feel special and inviting.
Pro Tips
- Use Room Temperature Ingredients: Allow your eggs and milk to come to room temperature before mixing. This helps to create a smooth, well-emulsified batter for a moist cake.
- Don't Overmix the Batter: Once you add the wet ingredients to the dry, mix only until combined. Overmixing can lead to a dense cake instead of a light and fluffy texture.
- Cool Completely Before Frosting: Ensure your cake layers are completely cool before frosting. This prevents the frosting from melting and sliding off the cake.
- Experiment with Flavors: Feel free to add a splash of espresso or coffee to the batter for a deeper chocolate flavor, or try adding a pinch of cinnamon for a warm spice note.
Variations
Chocolate Hazelnut Layer Cake Variations
You can change the flavor of your cake. Try adding espresso for a rich taste. A bit of orange zest also gives a nice twist. You can make this cake gluten-free by swapping the flour with a gluten-free mix. For a dairy-free option, use almond milk and a plant-based cream. This way, everyone can enjoy a slice.
Creative Frosting Alternatives
Switch up your frosting for fun! Use flavored whipped creams like vanilla or coffee. You can also try a rich chocolate ganache. To make ganache, heat cream and pour it over chocolate. Stir until smooth. Buttercream is another option. It’s sweet and creamy, perfect for a classic finish.

Storage Info
How to Store the Cake
Store your cake at room temperature for the best taste. Place it in a cake dome or cover it with plastic wrap. This keeps the cake moist and fresh. If your home is warm, refrigeration is a good idea. Store it in a container to prevent it from drying out.
Freezing the Cake
You can freeze your baked layers for later use. First, let the layers cool completely. Then, wrap each layer in plastic wrap tightly. Place them in a freezer-safe bag or container. This helps prevent freezer burn. When you are ready to serve, remove the layers from the freezer. Thaw them in the fridge for several hours or overnight. Once thawed, frost and enjoy your cake.
Shelf Life Expectations
Your chocolate hazelnut layer cake will last about 3 days at room temperature. If stored in the fridge, it can last up to a week. When frozen, it can stay good for up to 3 months. Look for signs of spoilage, like a dry texture or off smell. If you see mold, it’s best to toss the cake.
FAQs
Common Questions About the Recipe
Can I substitute ingredients in the recipe? Yes, you can swap some ingredients. For example, use almond flour instead of all-purpose flour for a gluten-free option. You can also use coconut milk instead of whole milk for a dairy-free version. Just know that these changes may affect the taste and texture.
How can I make this cake ahead of time? You can bake the cake layers a day in advance. After they cool completely, wrap them tightly in plastic wrap. Store them at room temperature.

Baking & Frosting Questions
Why is my cake not rising? If your cake does not rise, check your baking powder and baking soda. They need to be fresh. Also, make sure you mix the batter well. Not mixing enough can lead to dense cake. Finally, avoid opening the oven door too soon. This can cause the cake to sink.
