Double chocolate Cake — Easy & Delicious

By Jamie Cook — Home cook sharing tested recipes from a real kitchen.

double chocolate Cake is the answer when one chocolate layer simply refuses to be enough. This version combines deep cocoa flavor with melted chocolate and a glossy chocolate ganache, giving you a soft crumb without turning the cake into a brick disguised as dessert. It takes about 20 minutes to mix, then the oven does most of the heavy lifting. I made this with hot coffee in the batter, and the first thing I noticed was how dramatically it deepened the chocolate aroma without making the cake taste like coffee. If your idea of moderation involves adding more chocolate, welcome home.

Why This Recipe is Awesome

This double chocolate Cake earns its name honestly: cocoa powder and chocolate chips bring two distinct chocolate hits, while buttermilk keeps the crumb tender. You get a bakery-style layer cake without needing a pastry degree or seventeen mysterious ingredients from a specialty shop. The batter also comes together in one bowl, which means fewer dishes glaring at you from the sink. Frankly, the sink has contributed nothing to dessert, so it can wait.

Ingredients You’ll Need

• 2 cups (250 g) all-purpose flour — the structural backbone; please measure it instead of scooping like you’re panning for gold.
• ¾ cup (65 g) unsweetened cocoa powder — gives the cake its deep chocolate flavor.
• 1½ cups (300 g) granulated sugar — sweetness, because cocoa powder has absolutely no interest in being pleasant alone.
• 1½ teaspoons baking soda — gives the batter enough lift to rise properly.
• 1 teaspoon baking powder — extra insurance for a light crumb.
• ½ teaspoon fine salt — makes the chocolate taste more chocolatey.
• 2 large eggs, room temperature — bind everything together and help create a tender texture.
• 1 cup (240 ml) buttermilk — adds moisture and a gentle tang.
• ½ cup (120 ml) neutral vegetable oil — keeps the cake soft even after chilling.
• 2 teaspoons vanilla extract — rounds out the cocoa flavor.
• 1 cup (240 ml) hot brewed coffee — the secret weapon; it intensifies chocolate without turning the cake into a mocha.
• 1 cup (170 g) semisweet chocolate chips — the second chocolate hit and the occasional gooey pocket.
• 170 g semisweet or dark chocolate, finely chopped — for the ganache; use chocolate you actually enjoy eating.
• 180 ml heavy cream — turns chopped chocolate into smooth, spreadable ganache.
• 1 tablespoon unsalted butter — adds shine and makes the ganache extra silky.
• ¼ teaspoon salt — keeps the frosting from tasting flat.

Step-by-Step Instructions

1. Heat the oven to 350°F (175°C). Grease two 8-inch round cake pans and line the bottoms with parchment paper. The parchment matters because chocolate cake has a remarkable talent for bonding permanently with an unprepared pan.



2. Whisk the flour, cocoa powder, sugar, baking soda, baking powder, and salt together in a large bowl. Break up any cocoa lumps now, because nobody wants a surprise pocket of dry cocoa in their double chocolate Cake.
3. Whisk the eggs, buttermilk, oil, and vanilla in a second bowl until smooth. Pour the wet mixture into the dry ingredients and stir just until no large streaks of flour remain; don’t beat the batter aggressively.
4. Slowly pour in the hot coffee while stirring. The batter will become surprisingly thin, and that is completely normal. I made the mistake of assuming I’d ruined the batter the first time because it looked more like chocolate cream than cake batter, but it baked into a remarkably soft crumb.
5. Fold in the chocolate chips until evenly distributed. Keep the mixing gentle so you don’t develop excess gluten and end up with a chewy cake when you wanted something tender.
6. Divide the batter evenly between the prepared pans. Tap each pan lightly on the counter once or twice to release large air bubbles, but don’t repeatedly bang them around like you’re trying to settle concrete.
7. Bake at 350°F (175°C) for 30–35 minutes. The cakes are ready when the centers spring back lightly when pressed and a toothpick inserted near the center comes out with a few moist crumbs rather than wet batter.



8. Cool the cakes in their pans for 10 minutes. Run a thin knife around the edges, then turn the layers onto wire racks and remove the parchment; let them cool completely before adding ganache.
9. Make the ganache while the cakes cool. Heat the heavy cream until it just reaches a simmer, pour it over the chopped chocolate, and let it sit for 2 minutes before stirring slowly until smooth.
10. Add the butter and salt to the warm ganache. Stir until glossy, then let it cool for about 20–30 minutes, stirring occasionally, until it reaches a thick, spreadable consistency.
11. Place the first cake layer on a serving plate and spread a layer of ganache over the top. Set the second layer on top and cover the top and sides with the remaining ganache, using an offset spatula to create smooth or deliberately rustic swirls.
12. Let the finished cake sit for 20–30 minutes before slicing. This gives the ganache time to settle while keeping the crumb soft; serve at room temperature for the best texture.

Common Mistakes to Avoid

• Overmixing the batter: Stir until the flour disappears, then stop. Your whisk does not need a cardio workout.
• Using cold ingredients: Room-temperature eggs and buttermilk blend more evenly and help the batter behave predictably.
• Panicking over thin batter: Hot coffee makes this batter loose. Don’t “fix” it with extra flour.
• Frosting a warm cake: Warm layers melt ganache and create chocolate landslides. Cool them completely first.
• Overbaking the layers: Start checking around 30 minutes. A few moist crumbs beat a dry toothpick and a dry cake every time.

Alternatives & Substitutions

You can make this double chocolate Cake work with several easy pantry swaps without sacrificing its main appeal.

For a buttermilk substitute, stir 1 tablespoon lemon juice or white vinegar into 1 cup of milk and let it stand for 5 minutes. The result won’t taste exactly like cultured buttermilk, but it works well in the batter.

For an egg-free version, use a reliable commercial egg replacer according to its package directions. Because eggs affect the cake’s structure, avoid randomly replacing them with extra oil or milk.

If you don’t drink coffee, use hot water instead. Coffee intensifies cocoa flavor, but the cake will still bake successfully without it.

For darker chocolate flavor, use dark chocolate chips and 60–70% dark chocolate for the ganache. For a sweeter cake, stick with semisweet chocolate.

You can also add ½ cup chopped toasted pecans or walnuts to the batter for crunch. If you’re serving children who prefer a softer chocolate flavor, use milk chocolate chips instead.

For more chocolate desserts worth keeping in your baking rotation, try these easy chocolate brownies or make a batch of chocolate chip cookies when you want something smaller.

Frequently Asked Questions

How should I store double chocolate Cake?

Store the cake tightly covered at room temperature for up to 2 days if your kitchen stays reasonably cool, or refrigerate it for up to 4 days for longer storage. Let refrigerated slices sit at room temperature for about 20–30 minutes before serving so the ganache softens.

Can I make double chocolate Cake ahead of time?

Yes, you can bake the cake layers up to 1 day ahead and keep them tightly wrapped at room temperature once completely cool. Prepare and add the ganache the day you plan to serve the cake, or assemble everything ahead and refrigerate it until needed.

Why did my chocolate cake turn out dry?

A dry chocolate cake usually comes from overbaking or measuring too much flour. Pull the layers when a toothpick shows a few moist crumbs, and use a kitchen scale for the flour when possible rather than packing flour into a measuring cup.

Can I freeze double chocolate Cake?

Yes, you can freeze the unfrosted cake layers for up to 2 months when wrapped tightly in plastic wrap and then placed in a freezer-safe bag or container. Thaw them completely while still wrapped before frosting so condensation forms on the wrapping rather than directly on the cake.
