How to Make the Chocolate Cake

1. Prepare the Pan

Preheat your oven to 350°F (175°C).

Grease and line an 8-inch or 9-inch square cake pan with parchment paper.

For a taller layered cake, divide the batter between two square pans if available.

2. Mix the Dry Ingredients

In a large bowl, whisk together:

Flour
Cocoa powder
Sugar
Baking powder
Baking soda
Salt

Break up any cocoa lumps so the finished cake has a smooth texture.

3. Add the Wet Ingredients

Add the eggs, buttermilk, vegetable oil, and vanilla.

Mix until the batter is smooth and evenly combined.

Don’t overmix.

4. Add the Hot Coffee

Slowly pour in the hot coffee while stirring.

The batter will become quite thin. That’s completely normal.

Hot coffee enhances the chocolate flavor without necessarily making the finished cake taste like coffee.

If you prefer, you can substitute hot water.

5. Bake

Pour the batter into the prepared pan.

Bake for approximately 30–40 minutes, depending on the size and depth of your pan.

The cake is ready when a toothpick inserted into the center comes out with a few moist crumbs rather than wet batter.

Allow the cake to cool in the pan for about 10–15 minutes.

Transfer it to a cooling rack and allow it to cool completely.

For easier assembly, wrap the cooled cake and refrigerate it for at least 30 minutes before cutting.

Make the Chocolate-Hazelnut Frosting

Beat the softened butter with an electric mixer for approximately 3–4 minutes until light and creamy.

Gradually add the powdered sugar and cocoa powder.

Beat until smooth.

Add the chocolate-hazelnut spread, vanilla, and salt.

Beat again until completely incorporated.

Add heavy cream or milk, one tablespoon at a time, until the frosting reaches a smooth, spreadable consistency.

Beat for another 1–2 minutes until fluffy.

Prepare the Hazelnut Crunch

Place the roasted hazelnuts in a food processor and pulse briefly.

You want small pieces rather than a fine powder.

Mix the chopped hazelnuts with the crushed wafer cookies.

Set aside.

Assemble the Cake

1. Slice the Cake

Once completely cooled, carefully slice the cake horizontally into 2 or 3 even layers, depending on its height.

A long serrated knife makes this easier.

2. Add the First Layer

Place the first cake layer on a cake board or serving plate.

Spread a layer of chocolate-hazelnut frosting over the top.

Add a light sprinkling of the hazelnut-wafer crunch.

Drizzle or spread a small amount of chocolate-hazelnut spread over the crunch.

3. Add the Next Layer

Place the second cake layer on top.

Repeat the frosting and crunchy hazelnut filling.

Add the final cake layer.

4. Crumb Coat

Spread a thin layer of frosting around the entire cake.

This traps loose crumbs and gives you a cleaner final finish.

Refrigerate for 20–30 minutes.

5. Final Frosting Layer

Apply another layer of frosting to the top and sides.

Use a cake scraper or offset spatula to smooth the surface.

The square edges don’t have to be perfectly sharp. A slightly rustic finish looks beautiful with the chocolate drip and hazelnut decorations.

Refrigerate the cake again for at least 20 minutes before adding the drip.

Make the Chocolate Drip

Place the chopped chocolate in a heatproof bowl.

Warm the heavy cream until hot but not boiling.

Pour the cream over the chocolate and let it sit for about 2 minutes.

Stir slowly until smooth and glossy.

Allow the ganache to cool slightly.

It should be fluid enough to drip but not so hot that it melts the frosting.

Create the Chocolate Drip

Transfer a small amount of ganache to a piping bag or squeeze bottle.

Test one drip on the chilled cake.

If it runs too quickly all the way down the side, let the ganache cool for a few more minutes.

Once the consistency is right, pipe small amounts around the edge of the cake, allowing them to naturally run down the sides.

After completing the drip, spread the remaining ganache over the center of the cake.

Smooth gently with an offset spatula.

Decorate the Cake

Arrange Ferrero Rocher-style hazelnut chocolates around the top.

Add chopped roasted hazelnuts between the chocolates.

Finish with:

Chocolate curls
Hazelnut pieces
Chocolate-hazelnut spread
Gold sprinkles
Crushed wafers

For a professional bakery appearance, keep the decoration concentrated toward the center and edges rather than covering every inch of the cake.

Tips for the Perfect Drip Cake

Use Room-Temperature Ingredients

Room-temperature eggs, buttermilk, and butter generally combine more evenly and produce a smoother cake and frosting.

Don’t Overbake the Cake

Chocolate cake can dry out quickly if baked too long.

Start checking a few minutes before the expected baking time.

Chill Before Decorating

A cold, firm cake is much easier to frost and decorate.

Don’t Make the Ganache Too Hot

Hot ganache can melt the frosting and cause the drips to slide too far down the cake.

Test Your Drip

Always test one drip before decorating the entire cake.

This makes it much easier to adjust the ganache consistency.

Roast the Hazelnuts

Roasting intensifies the hazelnut flavor and gives the cake a more Ferrero-inspired taste.

Use a Serrated Knife

A serrated knife makes it easier to divide the cake into clean layers without compressing the sponge.

Easy Variations

Nutella-Style Chocolate Hazelnut Cake

Use your favorite chocolate-hazelnut spread throughout the filling and decoration.

Dark Chocolate Version

Use dark chocolate for the ganache and frosting for a richer, less-sweet cake.

Milk Chocolate Version

Use milk chocolate in the drip for a sweeter, softer chocolate flavor.

Hazelnut Praline Cake

Mix finely ground caramelized hazelnuts into the frosting for a deeper praline flavor.

Mini Square Cakes

Divide the batter among smaller square pans and create individual mini drip cakes for parties.

Chocolate Orange Version

Add a little orange zest to the cake and frosting and use dark chocolate for the drip.

How to Store the Cake

Because the frosting and ganache contain dairy, store the finished cake covered in the refrigerator.

It is best enjoyed within approximately 3–4 days.

For the best texture and flavor, allow individual slices to sit at room temperature for about 15–20 minutes before serving.

Can You Make It Ahead?

Yes.

The chocolate cake can be baked 1–2 days ahead.

Wrap it tightly and refrigerate it until you’re ready to assemble.

The frosting can also be prepared ahead and refrigerated. Bring it closer to room temperature and beat it again briefly before using if it has become firm.

The assembled cake can be decorated the day before serving.

Frequently Asked Questions

Can I make this cake without coffee?

Yes. Replace the hot coffee with hot water. Coffee simply enhances the chocolate flavor.

Can I use Nutella?

Yes. Chocolate-hazelnut spread works perfectly in the frosting, filling, and decoration.

Why is my cake dry?

The most common reasons are overbaking or adding too much flour. Measure flour accurately and begin checking the cake toward the end of the recommended baking time.

Why did my chocolate drip melt the frosting?

The ganache was probably too warm. Let it cool until slightly thickened before applying it to the chilled cake.

Can I use a round cake pan?

Absolutely. The recipe works in round pans, although the square shape gives the cake its distinctive appearance.

Can I freeze the cake?

The unfrosted chocolate cake layers can be wrapped tightly and frozen for up to about 2–3 months for best quality.

Thaw them in the refrigerator before assembling.

What can I use instead of Ferrero Rocher chocolates?

You can decorate the cake with whole roasted hazelnuts, chocolate truffles, wafer pieces, chocolate curls, or homemade hazelnut candies.
