Ingredients for Chocolate Cake with Chocolate Ganache

For the Chocolate Cake

• 1 cup all-purpose flour
• ½ cup unsweetened natural cocoa powder
• 1 cup granulated sugar
• ½ teaspoon baking powder
• 1 teaspoon baking soda
• ¼ teaspoon salt
• 1 large egg
• ½ cup milk
• ¼ cup sour cream
• ½ cup vegetable oil
• 1 teaspoon vanilla extract
• ½ cup hot brewed coffee

For the Glossy Chocolate Ganache

• 1 cup semi-sweet or dark chocolate, finely chopped
• ½ cup heavy cream

Ingredient Notes

Cocoa Powder: Use natural unsweetened cocoa powder for the best flavor and texture. Dutch-processed cocoa can change the cake’s rise since this recipe uses baking soda.

Coffee Substitute: If you prefer not to use coffee, substitute hot water. The coffee does not make the cake taste like coffee—it simply enhances the chocolate flavor.

Milk Options: Whole milk gives the richest texture, but 2% milk works well too.

Sour Cream Swap: Plain Greek yogurt can replace sour cream for a slightly lighter option while maintaining moisture.

Chocolate for Ganache: Choose high-quality semi-sweet or dark chocolate for a smooth, shiny finish. Chocolate chips can work, but bars melt more evenly.

Step-by-Step Instructions

Step 1 – Prepare the Pan and Oven

Preheat your oven to 350°F (175°C). Grease and line an 8-inch or 9-inch round cake pan with parchment paper for easy removal.

Step 2 – Mix the Dry Ingredients

In a large bowl, whisk together the flour, cocoa powder, sugar, baking powder, baking soda, and salt. Make sure there are no lumps in the cocoa.

Step 3 – Combine the Wet Ingredients

In a separate bowl, whisk the egg, milk, sour cream, vegetable oil, and vanilla extract until smooth and fully blended.

Step 4 – Make the Batter

Gradually add the wet ingredients to the dry mixture. Stir until just combined. Slowly pour in the hot coffee and mix gently. The batter will be thin—this is normal and ensures a moist cake.

Step 5 – Bake the Cake

Pour the batter into the prepared pan and smooth the top. Bake for 27–30 minutes, or until a toothpick inserted into the center comes out with a few moist crumbs.

Let the cake cool in the pan for 10 minutes, then transfer to a wire rack to cool completely before adding the ganache.

Step 6 – Make the Chocolate Ganache

Place the chopped chocolate in a heatproof bowl. Heat the heavy cream in a small saucepan until it just begins to simmer (do not boil). Pour the hot cream over the chocolate and let it sit undisturbed for 3–5 minutes.

Gently stir from the center outward until the mixture becomes smooth and glossy.

Step 7 – Add the Ganache

Pour the ganache over the cooled cake. Use a spatula to spread it evenly to the edges. Let it sit at room temperature until set, about 30–60 minutes.

Slice and serve.

Pro Tips for Success

1. Measure accurately. Spoon and level your flour to avoid a dense cake.
2. Don’t overmix. Stir just until combined to keep the crumb tender.
3. Use hot coffee. It blooms the cocoa and intensifies flavor.
4. Cool completely before frosting. Warm cake will melt the ganache.
5. Let ganache rest before stirring. This helps create a silky texture.
6. Use a sharp knife for clean slices. Wipe between cuts for neat presentation.

Flavor Variations

Orange Chocolate Cake: Add 1 teaspoon of finely grated orange zest to the batter for a citrus twist.

Mocha Version: Add ½ teaspoon espresso powder for a deeper, richer chocolate flavor.

Nutty Crunch: Sprinkle toasted chopped hazelnuts or almonds over the ganache before it sets.

Sea Salt Finish: Lightly sprinkle flaky sea salt on top for a sweet-and-salty balance.

Chocolate Raspberry: Serve with fresh raspberries or a thin layer of raspberry jam under the ganache.

Serving Suggestions

This chocolate cake pairs beautifully with a scoop of vanilla ice cream or freshly whipped cream. For a simple presentation, dust the edges with powdered sugar or top with fresh berries.

It’s perfect for birthdays, celebrations, dinner parties, or casual family desserts. Because it’s rich, small slices go a long way.

Serve at room temperature for the softest texture and most intense chocolate flavor.

Storage and Freezing Instructions

Room Temperature: Store covered at room temperature for up to 3 days.

Refrigerator: Keep in an airtight container for up to 5 days. Let slices come to room temperature before serving.

Freezing: Wrap individual slices tightly in plastic wrap and freeze for up to 2 months. Thaw overnight in the refrigerator or at room temperature for a few hours.

The ganache freezes well and maintains its smooth texture once thawed.

FAQ About Chocolate Cake with Chocolate Ganache

Why is hot coffee used in chocolate cake?

Hot coffee enhances the cocoa flavor without adding a strong coffee taste. It helps “bloom” the cocoa powder, making the chocolate flavor deeper and richer. If you prefer, you can substitute hot water.

How do I make my ganache extra glossy?

Use high-quality chocolate and avoid overheating the cream. Let the cream sit on the chocolate before stirring, and mix gently to prevent air bubbles. Avoid refrigerating while it sets, as rapid cooling can dull the shine.

Can I make this cake ahead of time?

Yes, this cake actually tastes even better the next day as the flavors develop. Bake and frost it a day ahead, then store covered at room temperature or in the refrigerator.

Can I turn this into cupcakes?

Absolutely. Divide the batter into lined cupcake tins and bake for 18–22 minutes. Spoon or dip each cupcake top into ganache once cooled.

Why is my cake dry?

Overbaking is the most common cause. Check the cake at the 27-minute mark and remove it as soon as a toothpick shows moist crumbs. Accurate measuring also helps maintain moisture.
