Gather these ingredients before you start. Each one plays a key role in our fluffy chocolate hazelnut layer cake. The all-purpose flour gives structure. Granulated sugar adds sweetness and moisture. Unsweetened cocoa powder brings that rich chocolate flavor.
The baking powder and baking soda help the cake rise. Salt enhances all the flavors. Eggs add richness and help bind the batter. Whole milk keeps the cake moist, while vegetable oil adds tenderness. Pure vanilla extract brings warmth to the cake.
Boiling water helps dissolve the cocoa, making the batter smooth. Hazelnuts provide crunch and a nutty taste. Hazelnut spread adds creamy richness between the layers.

Step-by-Step Instructions
Prepping the Oven and Pans
First, set your oven to 350°F (175°C). This is the right temperature for baking. While the oven heats, grease and flour two 9-inch round cake pans. This step helps the cakes slide out easily.
Mixing the Batter
In a large bowl, combine the dry ingredients. Add 1 ¾ cups of flour, 1 ½ cups of sugar, ¾ cup of cocoa powder, 1 ½ teaspoons of baking powder, 1 teaspoon of baking soda, and ½ teaspoon of salt. Whisk these well. Next, add 2 large eggs, 1 cup of milk, ½ cup of vegetable oil, and 2 teaspoons of vanilla extract. Beat this mix on medium speed for about 2 minutes. It should be smooth. Then slowly stir in 1 cup of boiling water. The batter will be thin. Finally, gently fold in 1 cup of toasted and chopped hazelnuts.
Baking the Cake
Now, divide the batter between the two pans. Bake for 30 to 35 minutes. To check if they are done, insert a toothpick into the center. If it comes out clean, the cakes are ready. Let them cool in the pans for 10 minutes. After that, move them to a wire rack to cool completely.
Cooling and Frosting Preparation
While the cakes cool, prepare the frosting. In a medium bowl, whip 2 cups of heavy cream with 4 tablespoons of powdered sugar. Whip until soft peaks form. Once the cakes are cool, place one layer on a plate. Spread hazelnut spread on top, then add a thick layer of whipped cream. Place the second layer on top and repeat the process. Use the remaining whipped cream to create peaks on top. Finish your cake with shaved dark chocolate and extra chopped hazelnuts.
Tips & Tricks
Achieving the Fluffiest Texture
To make a fluffy cake, use room temperature eggs and milk. Cold ingredients can make your cake dense. Let the eggs sit out for about 30 minutes. This small step can make a big difference.
Perfecting the Whipped Cream Frosting
When you whip cream, start with a cold bowl. This helps the cream whip better. Beat it on medium speed until soft peaks form. Keep an eye on it to avoid over-whipping.
Best Practices for Layering
Spread hazelnut spread evenly on the first layer. Use a spatula for a smooth finish. Stack the second layer gently to avoid crushing. Make sure the cake is cool to prevent sliding.
Pro Tips
- Use Room Temperature Ingredients: Make sure your eggs and milk are at room temperature before mixing. This helps the batter combine more smoothly and creates a better texture.
- Don't Overmix the Batter: Once you add the boiling water and fold in the hazelnuts, mix just until combined. Overmixing can lead to a dense cake.
- Cool Cakes Completely: Ensure the cakes are completely cooled before frosting. This prevents the whipped cream from melting and keeps your layers intact.
- Garnish for Presentation: Use a mix of shaved dark chocolate and chopped hazelnuts for a beautiful finish. Adding these elements enhances both flavor and visual appeal.
Variations
Alternative Frosting Options
You can change the frosting for this cake to suit your taste. A rich chocolate ganache is a great choice. Just melt chocolate with cream until smooth. This gives a shiny finish. You can also use cream cheese frosting for a tangy twist. Blend cream cheese with powdered sugar and vanilla for a creamy texture. Both options add a special touch to your cake.
Dietary Modifications
If you need gluten-free options, use a gluten-free flour blend. Make sure it has xantham gum for the best texture. For a dairy-free version, swap the milk for almond or oat milk. You can also use coconut cream instead of heavy cream for the frosting. These changes let everyone enjoy this treat without worry.
Flavor Enhancements
To make the flavor pop, consider adding espresso. Just mix in one tablespoon of instant espresso powder with the dry ingredients. This adds depth to the chocolate. You can also add orange zest for a fresh twist. The citrus brightens the cake and pairs well with chocolate. These small changes can make your cake unique and tasty.
Storage Info
Short-Term Storage
To keep your Fluffy Chocolate Hazelnut Layer Cake fresh, refrigerate it. Place the cake in an airtight container. This helps maintain moisture and flavor. You can also cover it with plastic wrap. The cake will stay good in the fridge for about 3 to 5 days.
Long-Term Storage
If you want to save the cake for later, freezing is a great option. First, let the cake cool completely. Wrap each layer tightly in plastic wrap. Then, place the wrapped layers in a freezer bag. This keeps out air and prevents freezer burn. You can freeze the cake for up to three months. When you are ready to enjoy it, thaw the cake in the fridge overnight.
Serving Recommendations
After storage, it’s easy to prepare the cake for serving. If frozen, let it thaw completely in the fridge. Once thawed, you can add fresh whipped cream if needed. You can also re-garnish with shaved chocolate and hazelnuts for a fresh look. This adds a nice touch and makes it ready for guests. Enjoy your cake with coffee or tea for a perfect pairing!
FAQs
Common Baking Questions
What should I do if my cake is too dry? If your cake is dry, you can fix it. Start by checking your oven temperature. An oven that is too hot can dry out your cake fast. Use an oven thermometer to get it right. Also, make sure not to overbake your cake. Keep an eye on the time, and check with a toothpick. If your cake is already baked, you can add a simple syrup. Mix equal parts sugar and water, then heat until the sugar dissolves. Brush this syrup on each layer. It adds moisture and flavor.
Ingredient Substitutions
What can I use instead of hazelnut spread? If you don't have hazelnut spread, don’t worry! You can use other spreads. Almond butter or peanut butter can work well. For a nut-free option, try sunflower seed butter. It gives a similar rich taste without nuts. You can also use chocolate frosting as a substitute. Just remember, the flavor will change slightly. Choose based on what you like and have at home.
Serving Size and Portions
How many servings does this cake make? This cake serves about 10 to 12 people. It has two layers, so you can cut each layer into 5 or 6 slices.
