Ingredients
List of Required Ingredients
- Dry Ingredients
- 2 cups all-purpose flour
- 1 ¾ cups granulated sugar
- ¾ cup unsweetened cocoa powder
- 1 ½ teaspoons baking powder
- 1 ½ teaspoons baking soda
- 1 teaspoon salt
- Wet Ingredients
- 2 large eggs
- 1 cup whole milk
- ½ cup vegetable oil
- 2 teaspoons vanilla extract
- 1 cup boiling water
- Ganache and Toppings
- 1 cup hazelnut spread (such as Nutella)
- 1 cup heavy whipping cream
- ½ cup hazelnuts, toasted and chopped
- 1 cup chocolate ganache
Gather these ingredients before you start. Fresh ingredients make a big difference. When you mix the dry ingredients, be sure to whisk them well. This helps the cake rise nicely. For the wet ingredients, using room temperature eggs and milk helps the batter mix better.
I love using hazelnut spread in the cream. It adds a rich flavor. Toasting hazelnuts brings out their best taste. You can do this in a pan on low heat. Just watch them closely, so they do not burn.
Prepare your chocolate ganache with care. Warm heavy cream will melt the chocolate smoothly. Let it cool slightly before using, so it thickens just enough. This cake will be a hit for any occasion!

Step-by-Step Instructions
Preheating and Preparing the Pans
Start by preheating your oven to 350°F (175°C). This is a key step. While it heats, prepare two 9-inch round cake pans. Grease them well with butter or oil, then dust with flour. This helps the cakes come out easily.
Mixing the Cake Batter
In a large bowl, whisk together the dry ingredients. Combine 2 cups of flour, 1 ¾ cups of sugar, ¾ cup of cocoa powder, 1 ½ teaspoons of baking powder, 1 ½ teaspoons of baking soda, and 1 teaspoon of salt. Mix until everything is even. Then, add 2 large eggs, 1 cup of whole milk, ½ cup of vegetable oil, and 2 teaspoons of vanilla extract. Beat on medium speed for about 2 minutes. Next, carefully stir in 1 cup of boiling water. The batter will be thin, but that’s okay.
Baking and Cooling the Cake Layers
Pour the batter evenly into the prepared pans. Bake for 30 to 35 minutes. Check if they are done by inserting a toothpick. It should come out clean. Let the cakes cool in the pans for 10 minutes. After that, transfer them to a wire rack to cool completely.
Preparing the Chocolate Ganache
To make the ganache, heat 1 cup of heavy cream in a saucepan over medium heat. Wait until it simmers, but do not let it boil. Remove it from the heat and pour it over 8 ounces of chopped semi-sweet chocolate. Let it sit for 5 minutes, then stir until smooth. Allow it to cool slightly, so it thickens.
Whipping the Hazelnut Cream
In a different bowl, whip 1 cup of heavy cream until soft peaks form. Now, fold in ½ cup of hazelnut spread. Mix gently until it is fully combined. This will add a rich flavor to your cake.
Assembling the Cake
When the cakes are cool, place one layer on a serving platter. Spread half of the hazelnut cream on top. Sprinkle with half of the chopped hazelnuts. Now, add the second layer on top. Spread the chocolate ganache over the top. Let it drip down the sides if you like. For the finishing touch, add the rest of the hazelnut cream and decorate with more chopped hazelnuts. Optionally, drizzle more ganache over the top for extra chocolate.
Tips & Tricks
Tips for Perfect Cake Layers
- Use room temperature ingredients. It helps them mix better.
- Grease and flour your pans well. This prevents sticking.
- Measure your flour correctly. Spoon it into the cup and level it off.
- Bake one layer at a time if your oven is small. This ensures even baking.
- Let the cakes cool fully before frosting. Warm cakes can melt your frosting.
How to Make a Smooth Ganache
- Start with good chocolate. Quality chocolate makes a big difference.
- Heat the cream gently until it simmers. Do not let it boil.
- Pour the cream over the chocolate and let it sit. This helps the chocolate melt evenly.
- Stir gently until smooth. Avoid overmixing, which can add air bubbles.
- Let the ganache cool before using. This will make it thicker and easier to spread.
Tricks for Fluffy Whipped Cream
- Chill your bowl and beaters. Cold tools mean better whipped cream.
- Use heavy cream for the best results. It whips up fluffiest.
- Start mixing on low speed. Gradually increase to medium as it thickens.
- Stop once you see soft peaks. Over-whipping can make it grainy.
- Fold in hazelnut spread gently. This keeps the cream light and airy.
Pro Tips
- Use Room Temperature Ingredients: Ensuring that your eggs, milk, and other ingredients are at room temperature helps create a smoother batter and results in a more tender cake.
- Don’t Overmix the Batter: Once you add the wet ingredients to the dry, mix just until combined. Overmixing can lead to a dense cake instead of a light and fluffy one.
- Cool Layers Completely: Allow the cake layers to cool completely before assembling. This prevents the frosting from melting and helps maintain the cake structure.
- Toast Hazelnuts for Extra Flavor: Toasting the hazelnuts enhances their flavor and adds a lovely crunch to your cake. Simply spread them on a baking sheet and toast in a 350°F oven for about 10 minutes.
Variations
Flavor Variations
You can change the taste of your cake. Add a mocha twist by mixing in espresso powder. Use 1 tablespoon of instant coffee or espresso powder with your dry mix. This gives a rich coffee flavor. If you want a lighter touch, try orange zest. Add 1 tablespoon of zest to your batter for a fresh hint.
Gluten-Free Options
For gluten-free cake, swap all-purpose flour for a gluten-free blend. Use a brand that has xanthan gum. This helps keep the cake fluffy. Follow the same steps in the recipe. You won't miss the gluten at all!
Alternative Frosting Ideas
Want to try different frostings? A cream cheese frosting pairs well. Mix 8 ounces of cream cheese with ½ cup of powdered sugar and 1 teaspoon of vanilla. Whip it until smooth. You can also use whipped coconut cream for a dairy-free option. Simply replace heavy cream with coconut cream. It adds a tropical vibe!
Storage Info
Best Ways to Store the Cake

Freezing Instructions
If you want to save some cake for later, freezing is a great option! First, let the cake cool completely. Then, slice it into individual pieces or keep it whole. Wrap each piece tightly in plastic wrap. Place the wrapped cake in a freezer bag or airtight container. This will prevent freezer burn and keep it fresh for up to three months.

FAQs
Can I use a different nut butter instead of hazelnut spread?
Yes, you can. Almond butter or peanut butter works well. Each nut butter adds its own taste. Just consider how the flavor will mix with chocolate. Almond butter has a mild flavor, while peanut butter is stronger. Adjust your recipe to suit your taste.
What is the best way to ensure my cake is moist?
To keep your cake moist, use oil instead of butter. Oil helps to retain moisture better. Also, do not overbake your cake. Check it with a toothpick to avoid dryness. Adding a bit of sour cream or yogurt can also help. These ingredients add moisture without making the cake dense.
How do I know when my cake is fully baked?
Your cake is ready when a toothpick comes out clean. Insert it in the center of the cake. If it has batter on it, bake a few more minutes. Cakes should spring back when gently pressed. Trust your senses; the smell will fill your kitchen when it's close.
Can I make this cake ahead of time?
Yes, you can make this cake ahead of time. Bake the cake layers and let them cool completely. Wrap them tightly in plastic wrap. Store them in the fridge for up to three days. You can also freeze the layers for up to three months. Just remember to thaw them before frosting.
How to fix a cake that has sunk in the middle?
If your cake sinks, it might be underbaked. Check your oven’s temperature with a thermometer. If it’s too low, the cake won’t rise well. You can also fill the sinkhole with whipped cream or ganache. This way, you can still enjoy your cake’s taste and look.
