Ingredients

For the Chocolate Cake

1 ¾ cups all-purpose flour
¾ cup unsweetened cocoa powder
1 ½ cups granulated sugar
1 ½ teaspoons baking powder
1 ½ teaspoons baking soda
½ teaspoon salt
2 large eggs
1 cup whole milk
½ cup vegetable oil
2 teaspoons vanilla extract
1 cup hot water or hot brewed coffee

For the Chocolate Ganache

8 ounces semisweet chocolate, finely chopped
1 cup heavy cream
1 tablespoon unsalted butter

For Decoration

Chocolate curls, as needed
Fresh mint leaves, for garnish

Step-by-Step Instructions

1. Prepare the Cake Batter

Preheat your oven to 350°F (175°C). Grease two 8-inch round cake pans and line the bottoms with parchment paper.

In a large bowl, whisk together the flour, cocoa powder, sugar, baking powder, baking soda, and salt.

Add the eggs, milk, vegetable oil, and vanilla extract. Mix until the ingredients are well combined and the batter is smooth.

Slowly pour in the hot water or hot coffee while mixing gently. The batter will become fairly thin, which is normal and helps create a moist chocolate cake.

2. Bake the Cake

Divide the batter evenly between the prepared cake pans.

Bake for 25–30 minutes, or until a toothpick inserted into the center comes out with a few moist crumbs.

Remove the cakes from the oven and allow them to cool in the pans for about 10 minutes. Carefully transfer them to a wire rack and let them cool completely.

3. Make the Chocolate Ganache

Place the chopped chocolate in a heatproof bowl.

Heat the heavy cream in a small saucepan over medium heat until it is hot and just beginning to simmer. Do not boil it vigorously.

Pour the hot cream over the chocolate and let it sit for about 2–3 minutes.

Stir slowly until the chocolate has completely melted and the mixture becomes smooth and glossy. Stir in the butter until incorporated.

Let the ganache cool at room temperature until it thickens to a spreadable consistency.

4. Assemble the Cake

Place one cooled cake layer on a serving plate.

Spread a layer of chocolate ganache over the top.

Place the second cake layer on top and gently press it into position.

Spread the remaining ganache over the top and sides of the cake. For a look similar to the pictured cake, allow some of the ganache to naturally flow slightly toward the edges.

5. Decorate

Arrange chocolate curls generously over the top of the cake.

Add a few fresh mint leaves for color and freshness.

For the cleanest slices, allow the finished cake to chill for about 30 minutes before serving.

Tips & Substitutions

Use good-quality chocolate: Since the ganache is a major part of the dessert, good chocolate makes a noticeable difference.
Don’t overbake: Remove the cake as soon as a toothpick comes out with a few moist crumbs.
Cool completely: Warm cake can cause the ganache to melt and slide.
For stronger chocolate flavor: Use hot brewed coffee instead of water. It enhances the chocolate flavor without making the cake taste strongly of coffee.
For a sweeter cake: Use milk chocolate instead of semisweet chocolate for the ganache.
For a darker chocolate flavor: Use dark chocolate with a higher cocoa percentage.
For easier chocolate curls: Chill a chocolate bar briefly, then use a vegetable peeler to shave thin curls from the side.

Storage Instructions

Store the finished chocolate ganache cake covered in the refrigerator for up to 4 days.

Allow individual slices to sit at room temperature for about 15–20 minutes before serving for the best texture.

The unfrosted cake layers can also be wrapped tightly and refrigerated for up to 3 days. For longer storage, freeze the wrapped cake layers for up to 2 months and thaw them completely before decorating.

Serving Suggestions

Serve each slice with extra chocolate curls and a small fresh mint leaf.

For an extra-indulgent dessert, pair it with:

Vanilla ice cream
Whipped cream
Fresh berries
A dusting of cocoa powder
A drizzle of warm chocolate sauce
Coffee or espresso

Variations

Chocolate Raspberry Ganache Cake

Add a thin layer of raspberry jam between the cake layers before adding the ganache. The tart berries provide a delicious contrast to the rich chocolate.

Dark Chocolate Ganache Cake

Use dark chocolate for the ganache and slightly reduce the sweetness of the cake for a more intense chocolate dessert.

Chocolate Orange Cake

Add 1–2 teaspoons of finely grated orange zest to the cake batter and a little orange zest to the ganache.

Chocolate Mint Cake

Add ½ teaspoon of peppermint extract to the ganache and decorate with fresh mint leaves for a refreshing chocolate-mint flavor.

Mini Chocolate Ganache Cakes

Bake the batter in smaller cake pans or use a muffin-style pan to create individual chocolate desserts. Adjust the baking time and check them early to prevent overbaking.
