Why This Recipe Works
🍳 What You'll Need for This Recipe
Essential tools to make this recipe perfectly
This recipe isn’t just thrown together; it’s carefully crafted to deliver the perfect double chocolate experience. Here’s why it works:
- Cocoa Powder Power: We use both Dutch-processed and natural cocoa powder. Dutch-processed cocoa provides a deep, mellow flavor and contributes to the cake’s dark color, while natural cocoa powder adds a slightly acidic tang that balances the sweetness and enhances the chocolate intensity.
- Buttermilk Magic: Buttermilk adds moisture and tenderness to the cake, creating a soft and delicate crumb. Its acidity also reacts with the baking soda, providing extra lift and a light, airy texture.
- Hot Coffee Boost: Adding hot coffee to the batter intensifies the chocolate flavor and creates a richer, more complex taste. Don’t worry, the coffee flavor itself won’t be noticeable – it just enhances the chocolate!
- Oil and Butter Combination: Using both oil and butter provides the perfect balance of moisture and flavor. Oil keeps the cake incredibly moist for days, while butter adds richness and a classic buttery taste.
- The Ganache Finale: A simple yet decadent chocolate ganache completes the cake, adding a final layer of intense chocolate flavor and a beautiful, glossy finish. The ratio of chocolate to cream is crucial for achieving the perfect consistency – smooth, pourable, and utterly irresistible.
Ingredients
For the Cake:
- 2 cups all-purpose flour
- 2 cups granulated sugar
- ¾ cup Dutch-processed cocoa powder
- ¼ cup natural cocoa powder
- 1 ½ teaspoons baking powder
- 1 ½ teaspoons baking soda
- 1 teaspoon salt
- 1 cup buttermilk
- ½ cup vegetable oil
- 2 large eggs
- 2 teaspoons vanilla extract
- 1 cup hot coffee
For the Ganache:
- 8 ounces semi-sweet chocolate, chopped
- 1 cup heavy cream
- 2 tablespoons unsalted butter, softened (optional, for extra shine)

Instructions
- Preheat and Prep: Preheat your oven to 350°F (175°C). Grease and flour two 9-inch round cake pans. You can also line the bottoms with parchment paper circles for easy removal.
- Combine Dry Ingredients: In a large bowl, whisk together the flour, sugar, Dutch-processed cocoa powder, natural cocoa powder, baking powder, baking soda, and salt.
- Combine Wet Ingredients: In a separate bowl, whisk together the buttermilk, oil, eggs, and vanilla extract.
- Combine Wet and Dry: Gradually add the wet ingredients to the dry ingredients, mixing on low speed until just combined. Be careful not to overmix.
- Add Coffee: Slowly pour in the hot coffee, mixing until the batter is smooth and slightly thin. Don’t worry, this is normal!
- Divide and Bake: Divide the batter evenly between the prepared cake pans. Bake for 30-35 minutes, or until a wooden skewer inserted into the center comes out clean or with a few moist crumbs attached.
- Cool Completely: Let the cakes cool in the pans for 10-15 minutes before inverting them onto a wire rack to cool completely. This is crucial to prevent the cakes from breaking.
- Prepare the Ganache: While the cakes are cooling, prepare the ganache. Place the chopped chocolate in a heatproof bowl.
- Heat the Cream: In a saucepan, heat the heavy cream over medium heat until it just begins to simmer. Do not boil.
- Pour and Stir: Pour the hot cream over the chopped chocolate and let it sit for 1 minute to soften the chocolate. Then, gently stir until the chocolate is completely melted and the ganache is smooth and glossy. Stir in the softened butter (if using).
- Assemble the Cake: Once the cakes are completely cool, place one layer on a serving plate or cake stand. Pour about half of the ganache over the top, spreading it evenly.
- Stack and Finish: Carefully place the second cake layer on top of the ganache. Pour the remaining ganache over the top layer, allowing it to drip down the sides for a dramatic effect.
- Let Set: Let the ganache set for at least 30 minutes before serving. You can speed up the process by refrigerating the cake for a shorter period.
- Serve and Enjoy! Slice and serve this decadent double chocolate cake. Enjoy every bite!
Tips for Success
- Measure Accurately: Baking is a science, so accurate measurements are crucial. Use measuring cups and spoons specifically designed for baking.
- Don’t Overmix: Overmixing the batter develops the gluten in the flour, resulting in a tough cake. Mix until just combined.
- Use Room Temperature Ingredients: Using room temperature ingredients, especially the eggs and buttermilk, helps them emulsify properly, creating a smoother batter and a more tender cake.
- Cool Completely: Allow the cakes to cool completely before frosting. Otherwise, the ganache will melt and slide off.
- Adjust Baking Time: Oven temperatures can vary, so keep an eye on the cake while it’s baking. Use a wooden skewer to check for doneness.
- Get Creative with Decorations: While the ganache is the star, feel free to add other decorations, such as chocolate shavings, fresh berries, or a dusting of cocoa powder.
Storage Instructions
Store leftover double chocolate cake in an airtight container at room temperature for up to 3 days, or in the refrigerator for up to 5 days. The cake may become slightly drier in the refrigerator, so it’s best to let it come to room temperature before serving. You can also freeze individual slices of cake for up to 2 months. Wrap the slices tightly in plastic wrap and then place them in a freezer-safe bag or container.

FAQ
Q: Can I use all Dutch-processed cocoa powder?
A: Yes, you can. The cake will be slightly less tangy, but still delicious. Use ¾ cup + ¼ cup (total 1 cup) of Dutch-processed cocoa powder.
Q: Can I use all natural cocoa powder?
A: We don’t recommend it. The cake will be more acidic and may not rise as well.
Q: Can I use milk instead of buttermilk?
A: Buttermilk is preferred for its acidity and moisture. If you don’t have buttermilk, you can make a substitute by adding 1 tablespoon of lemon juice or white vinegar to 1 cup of milk and letting it sit for 5 minutes.
Q: Can I use a different type of chocolate for the ganache?
A: Yes, you can use milk chocolate, dark chocolate, or even white chocolate, depending on your preference. Adjust the amount of cream accordingly – use less cream for darker chocolate and more cream for milk or white chocolate.
Q: My ganache is too thick/thin. What do I do?
A: If the ganache is too thick, add a tablespoon of warm cream at a time until it reaches the desired consistency. If the ganache is too thin, refrigerate it for 15-30 minutes to allow it to thicken.
