What You’ll Need

For the Chocolate Cake:

4 large eggs (room temperature)
1 3/4 cups (220g) all-purpose flour
3/4 cup (75g) unsweetened cocoa powder
1 3/4 cups (350g) granulated sugar
2 teaspoons baking soda
1 teaspoon baking powder
1 teaspoon salt
1 cup (240ml) buttermilk
1/2 cup (120ml) vegetable oil
2 teaspoons vanilla extract
1 cup (240ml) hot coffee or hot water
4 oz (115g) dark chocolate, chopped and melted

For Simple Chocolate Ganache (Optional):

1/2 cup (120ml) heavy cream
4 oz (115g) dark chocolate, chopped

Substitution Notes:

Buttermilk: Make your own by adding 1 tablespoon lemon juice to 1 cup regular milk
Coffee: Enhances chocolate flavor but can be replaced with hot water
Dark chocolate: Semi-sweet chocolate chips work as a substitute
Oil: Can use melted butter (cooled) but oil keeps the cake more moist

Step-by-Step Directions

Preheat and prepare. Preheat your oven to 350°F (175°C). Grease two 9-inch round cake pans with butter, then dust with cocoa powder (not flour) for extra chocolate flavor. Line the bottoms with parchment paper for easy removal.
Melt your chocolate. Melt the 4 oz of dark chocolate using a double boiler or microwave in 30-second intervals, stirring between each interval until smooth. Set aside to cool slightly.

Pro Tip: Don’t skip the chocolate melting step – it adds richness that cocoa powder alone can’t provide.

Combine dry ingredients. In a large bowl, whisk together flour, cocoa powder, sugar, baking soda, baking powder, and salt. Make sure there are no lumps, especially in the cocoa powder.
Mix wet ingredients. In another bowl, whisk the 4 eggs until well beaten. Add buttermilk, vegetable oil, vanilla extract, and the melted chocolate. Whisk until everything is well combined and smooth.
Combine wet and dry. Pour the wet ingredients into the dry ingredients and stir with a wooden spoon or rubber spatula until just combined. Don’t overmix – a few lumps are okay.
Add the hot coffee. Here’s where the magic happens: slowly stir in the hot coffee or hot water. The batter will become quite thin – this is exactly what you want! The hot liquid helps bloom the cocoa and creates that incredibly moist texture.

Don’t Panic: The batter will look very thin, almost pourable. This is normal and creates the moist, tender crumb.

Divide and bake. Divide the batter evenly between your prepared pans. Bake for 30-35 minutes, or until a toothpick inserted in the center comes out with just a few moist crumbs (not completely clean – that means it’s overbaked).
Cool properly. Let the cakes cool in their pans for 15 minutes, then turn them out onto wire racks to cool completely before frosting.

Common Questions

Why does this recipe use both cocoa powder and melted chocolate?

Cocoa powder provides the chocolate structure and deep flavor, while melted chocolate adds richness and moisture. Together, they create a more complex, intense chocolate taste than using just one or the other.

Can I make this as a sheet cake instead?

Absolutely! Pour the batter into a greased and cocoa-dusted 9×13 inch pan. Bake for 35-40 minutes, checking for doneness with a toothpick. This is perfect for casual gatherings or potluck desserts.

Why is coffee added to chocolate cake?

Coffee enhances and intensifies chocolate flavor without making the cake taste like coffee. The hot liquid also helps create a more tender, moist crumb. If you’re caffeine-sensitive, hot water works too, though you’ll miss some of the flavor depth.

How do I know when it’s done baking?

The cake should spring back lightly when touched in the center, and a toothpick should come out with a few moist crumbs (not wet batter, but not completely clean either). Chocolate cakes are better slightly underbaked than overbaked.

Can I use this recipe for cupcakes?

Yes! Divide the batter among 18-20 lined muffin cups, filling each about 2/3 full. Bake at 350°F for 18-22 minutes. This makes perfect chocolate cupcakes for parties or lunchboxes.

What’s the best frosting for this cake?

This rich cake pairs beautifully with many frostings: classic chocolate buttercream, cream cheese frosting, peanut butter frosting, or simple vanilla buttercream. The ganache recipe provided is also perfect for a sophisticated finish.
