Cook Time: 30 minutes

Total Time: 1 hour 20 minutes (includes cooling)

Servings: 12 slices

Ingredients

For the Cake

• 1 ¾ cups (220g) all-purpose flour
• ¾ cup (65g) unsweetened cocoa powder, natural or Dutch-process
• 1 ½ teaspoons baking soda
• ½ teaspoon baking powder
• 1 teaspoon fine sea salt
• 2 cups (400g) granulated sugar
• 2 large eggs, room temperature
• ½ cup (120ml) vegetable oil or neutral oil
• ¼ cup (57g) unsalted butter, melted
• 1 cup (240ml) buttermilk, room temperature
• 2 teaspoons pure vanilla extract
• 1 cup (240ml) hot brewed coffee (or hot water)

For the Chocolate Ganache Frosting

• 12 oz (340g) semi-sweet or bittersweet chocolate, finely chopped
• 1 ¼ cups (300ml) heavy cream
• 2 tablespoons unsalted butter, softened
• Pinch of sea salt

Ingredient Notes

• Cocoa powder: Natural cocoa has a slightly tangier, classic flavor, while Dutch-processed cocoa produces a darker color and a smoother taste. Either works here since the leaveners are balanced for both.
• Coffee: You won’t taste coffee in the finished cake. It simply deepens the chocolate flavor. If you’d rather skip it, hot water works fine, though the chocolate notes will be a touch milder.
• Buttermilk: This adds tenderness and a subtle tang that balances the sweetness. No buttermilk on hand? Stir 1 tablespoon of white vinegar or lemon juice into 1 cup of regular milk and let it sit for 5 minutes.
• Oil and butter combination: Oil keeps the cake moist for days, while the melted butter adds flavor that oil alone can’t provide. Don’t swap all the oil for butter, or the crumb will turn drier once cooled.
• Chocolate for ganache: Use real chocolate bars or high-quality baking chocolate rather than chocolate chips, which contain stabilizers that can make the ganache grainy or prevent it from melting smoothly.

Kitchen Equipment Needed

• Two 9-inch round cake pans (or one 9×13-inch pan)
• Mixing bowls (one large, one medium)
• Whisk and rubber spatula
• Measuring cups and spoons
• Wire cooling rack
• Offset spatula for frosting
• Parchment paper

Step-by-Step Instructions:

1. Preheat and prep your pans. Set your oven to 350°F (175°C). Grease two 9-inch round cake pans, line the bottoms with parchment paper, and dust with a little cocoa powder instead of flour so you don’t leave white streaks on the finished cake.
2. Whisk the dry ingredients. In a large bowl, whisk together the flour, cocoa powder, baking soda, baking powder, and salt. Whisking thoroughly here breaks up any cocoa clumps, which prevents bitter pockets in your finished slice.
3. Combine the sugar and wet ingredients. In a separate bowl, whisk the sugar, eggs, oil, and melted butter until smooth. Add the buttermilk and vanilla, whisking until fully combined.
4. Bring the batter together. Pour the wet mixture into the dry ingredients and whisk just until no streaks of flour remain. Overmixing at this stage develops excessive gluten, resulting in a tougher, less tender cake.
5. Add the hot coffee. Slowly pour in the hot coffee while whisking. The batter will turn noticeably thin — that’s exactly what you want. A thinner batter is what gives this cake its signature moist, fudgy texture.
6. Divide and bake. Split the batter evenly between your prepared pans. Bake for 28 to 32 minutes, or until a toothpick inserted in the center comes out with a few moist crumbs, not wet batter.
7. Cool completely. Let the cakes rest in their pans for 10 minutes, then turn them out onto a wire rack to cool fully. Frosting a warm cake will cause the ganache to slide right off, so patience matters here.
8. Make the ganache. Place the chopped chocolate in a heatproof bowl. Heat the cream until it just starts to simmer, then pour it over the chocolate. Let it sit undisturbed for 2 minutes, then stir from the center outward until glossy and smooth. Stir in the butter and salt.
9. Let the ganache set slightly. Allow the ganache to cool at room temperature for 20 to 30 minutes until it thickens to a spreadable consistency, similar to frosting rather than a pourable glaze.
10. Assemble the cake. Place one cake layer on a serving plate, spread a generous layer of ganache on top, then stack the second layer. Cover the top and sides with the remaining ganache using an offset spatula.
11. Slice and serve. Let the frosted cake set for about 15 minutes before slicing so the layers hold together cleanly.

Pro Tips

• Weigh your flour if you have a kitchen scale. Scooping flour directly with a measuring cup can pack in up to 20% more than intended, leading to a dry cake.
• Room-temperature eggs and buttermilk blend more evenly into the batter, which helps the cake rise consistently.
• Don’t skip lining the pans with parchment. Chocolate cake batter is delicate and tends to stick even with greasing alone.
• Test doneness a few minutes early. Chocolate cakes can look underdone due to their dark color, so rely on the toothpick test rather than visual cues.

Common Mistakes to Avoid

• Overbaking: Because the batter is dark, it’s easy to leave the cake in too long “just to be safe.” This dries it out fast. Pull it as soon as moist crumbs appear on the toothpick.
• Skipping the coffee or hot liquid: The hot liquid blooms the cocoa powder, intensifying flavor. Using cold liquid noticeably mutes the chocolate taste.
• Frosting a warm cake: This causes the frosting to melt, slide, and leave a messy finish. Always cool completely first.
• Using chocolate chips for ganache: They often won’t melt into a fully smooth texture because of the added stabilizers.
• Overmixing the batter: This leads to a denser, chewier crumb instead of a tender one.

Variations

1. Chocolate Peanut Butter Cake: Swap the ganache for a peanut butter buttercream and drizzle melted chocolate on top.
2. Mocha Chocolate Cake: Increase the coffee slightly and add 1 teaspoon of instant espresso powder to the batter for a bolder coffee-chocolate flavor.
3. Chocolate Raspberry Cake: Spread a thin layer of raspberry jam between the cake layers before adding ganache.
4. Spiced Chocolate Cake: Add ½ teaspoon of cinnamon and a pinch of cayenne for a warm, subtly spicy version.
5. Chocolate Orange Cake: Add 1 tablespoon of orange zest to the batter and a few drops of orange extract to the ganache.
6. Gluten-Free Version: Substitute a 1:1 gluten-free flour blend for the all-purpose flour. Texture will be slightly denser but still moist.
7. Cupcake Version: Divide the batter into a lined muffin tin and bake at 350°F for 18 to 20 minutes, yielding about 24 cupcakes.

Storage Instructions

Store the frosted cake in an airtight container at room temperature for up to 2 days, or in the refrigerator for up to 5 days. If refrigerated, let slices sit at room temperature for about 20 minutes before serving so the crumb softens back up.

Freezing Instructions

Unfrosted cake layers freeze exceptionally well. Wrap each cooled layer tightly in plastic wrap, then foil, and freeze for up to 3 months. Thaw overnight in the refrigerator before frosting. Frosted cake can also be frozen; freeze uncovered for 1 hour first so the ganache sets, then wrap carefully to avoid smudging.

Reheating Instructions

This cake is best enjoyed at room temperature and doesn’t require reheating. If you prefer a slightly warm slice, microwave an unfrosted piece for 10 to 12 seconds.

Make Ahead Tips

• Bake the cake layers up to 2 days ahead, wrap tightly, and store at room temperature.
• Ganache can be made a day in advance; store covered at room temperature and re-whisk briefly before spreading if it firms up too much.
• Assemble the final cake the day you plan to serve it for the freshest presentation.

What to Serve With This Recipe

• A scoop of vanilla bean ice cream
• Fresh raspberries or strawberries for acidity to balance the richness
• A cup of black coffee or espresso
• Lightly sweetened whipped cream
• A glass of cold milk is a classic pairing

Troubleshooting Section

My cake sank in the middle. This usually means the oven wasn’t fully preheated, or the pan was opened too early during baking. Use an oven thermometer to confirm accuracy and avoid opening the door before the 25-minute mark.

My cake is dry. This typically points to overbaking or too much flour. Measure flour by weight next time and start checking for doneness a few minutes before the suggested time.

My ganache is grainy or separated. This happens when chocolate overheats or seizes due to exposure to moisture. Gently rewarm the ganache over a double boiler while whisking in a small splash of warm cream to bring it back together.

My cake layers domed too much. High oven temperatures or too much baking powder can cause doming. Confirm your oven temperature and consider using cake strips around the pans for more even baking.

Expert Tips

• Bloom your cocoa powder in the hot coffee for the deepest chocolate flavor.
• A serrated knife makes leveling cake layers far easier than a regular knife.
• Crumb-coat the cake with a thin layer of ganache, then chill for 15 minutes before adding the final frosting layer for a cleaner finish.
• Room-temperature ingredients emulsify more evenly, giving you a smoother batter and more consistent crumb.
