Why This Dark Chocolate Ganache Cake Stands Out

A Rich, Bittersweet Chocolate Experience

This cake is built on the deep flavor of bittersweet chocolate, blended with freshly brewed hot coffee, creating a complexity that amplifies every bite. The harmony of the two ingredients elevates the chocolate experience to new levels.

A Recipe Perfected Over Generations

This dessert has evolved through years of baking tradition. Carefully refined, each ingredient plays a role in achieving the silky texture, moist crumb, and luxurious frosting that define this cake.

Designed for Celebration

From holidays to birthdays, anniversaries to dinner parties, this cake has been the centerpiece of countless special events. Its elegant glossy ganache and flawless structure make it an unforgettable showpiece.

Unmatched Moisture and Structure

Thanks to buttermilk, eggs, and the ideal blend of leavening agents, the cake achieves a tender crumb that stays moist for days.

Ingredients for the Best Dark Chocolate Ganache Cake

For the Cake Layers

• 6 oz bittersweet chocolate, chopped
• 1 1/2 cups hot brewed coffee
• 4 large eggs
• 3 cups sugar
• 3/4 cup canola oil
• 2 teaspoons vanilla extract
• 2 1/2 cups all-purpose flour
• 1 cup cocoa powder
• 2 teaspoons baking soda
• 3/4 teaspoon baking powder
• 1 1/4 teaspoons salt
• 1 1/2 cups buttermilk

For the Silky Dark Chocolate Ganache

• 16 oz bittersweet chocolate, chopped
• 2 cups heavy whipping cream
• 5 teaspoons light corn syrup
• (Optional: 3 tablespoons confectioners’ sugar for added sweetness*)*

How to Make Dark Chocolate Ganache Cake

1. Preparing the Cake Batter

Begin by preheating the oven to 325°F (163°C). Prepare three 8-inch round cake pans by greasing them, lining the bottoms with parchment, and greasing again. This ensures effortless removal after baking.

Melt the Chocolate

Place chopped bittersweet chocolate in a medium bowl. Pour hot brewed coffee over the chocolate and whisk until it becomes smooth and glossy. Set aside to cool for 10–15 minutes.

Beat the Wet Ingredients

In a large mixing bowl, beat the eggs on high speed until pale and creamy, achieving the ideal texture for structure. Slowly incorporate sugar, canola oil, vanilla, and the cooled chocolate mixture, mixing until silky and fully combined.

Combine the Dry Ingredients

In a separate bowl, sift together:

• all-purpose flour
• cocoa powder
• baking soda
• baking powder
• salt

Sifting eliminates clumps and ensures an even rise.

Bring It All Together

Add the dry ingredients to the chocolate mixture in alternating portions with the buttermilk. Mix between each addition, creating a smooth and pourable batter with a deep chocolate scent.

2. Baking the Cake Layers

Divide the batter evenly into the prepared pans.

Bake for 30–35 minutes, or until a toothpick inserted into the center comes out clean.

Cool the cakes in their pans for 10 minutes before transferring to a wire rack to cool completely. Proper cooling prevents melting the ganache during assembly.

Creating the Perfect Ganache Frosting

1. Preparing the Ganache

Place the chopped bittersweet chocolate into a medium bowl. In a saucepan, heat the heavy cream and corn syrup until just boiling.

Pour the hot cream mixture over the chocolate. Allow it to sit for 1 minute to begin melting, then whisk gently until smooth and luxurious.

For a sweeter finish, whisk in confectioners’ sugar.

Let the ganache cool for 45–50 minutes. As it rests, it transforms into a perfectly spreadable consistency—a glossy frosting that glides effortlessly over the cake layers.

2. Frosting the Cake

Once the layers have cooled:

1. Place the first layer on a serving plate and spread 1/3 cup of ganache across the top.
2. Repeat with the second layer.
3. Place the final layer on top and generously frost the top and sides, smoothing it into a sleek, elegant finish.

The result is a rich, dark chocolate masterpiece that invites admiration before the first slice is cut.

Serving Suggestions & Storage Tips

Serve at Room Temperature

Ganache softens beautifully at room temperature, offering the ideal silky-smooth texture.

Short-Term Storage

Store the frosted cake in an airtight container:

• Room temperature: up to 2 days
• Refrigerator: up to 1 week

Freezing Options

Freeze unfrosted layers by wrapping them tightly in plastic wrap. They can be stored for up to 3 months and thaw beautifully for assembly later.

Expert Tips for a Show-Stopping Ganache Cake

Use High-Quality Chocolate

Premium bittersweet chocolate drastically improves flavor and ganache texture.

Brew Fresh Coffee

Hot, freshly brewed coffee brings out richer cocoa notes—avoid instant coffee for this recipe.

Consistency Is Key

Allow ganache to cool long enough to thicken, but not so long that it becomes too stiff to spread.

Level the Layers

Trim any domed tops for beautifully stacked layers that look bakery-perfect.

A Cake Worth Every Celebration

The Dark Chocolate Ganache Cake is more than a dessert—it is a tradition of indulgence, elegance, and joy. With its moist chocolate crumb, deep cocoa richness, and silky ganache coating, it continues to captivate guests and elevate special occasions. Whether served at a holiday feast, a birthday celebration, or simply as a luxurious treat, this cake promises unforgettable flavor in every bite.
