Ingredients

For the Chocolate Cake

• 2 cups granulated sugar (400 g)
• 1¾ cups all-purpose flour (245 g)
• ¾ cup unsweetened cocoa powder (75 g)
• 1½ teaspoons baking powder
• 1½ teaspoons baking soda
• ½ teaspoon salt
• 2 large eggs
• 1 cup warm water or brewed coffee (240 ml)
• 1 cup milk (240 ml)
• ½ cup vegetable oil (120 ml)
• 1½ teaspoons vanilla extract

For the Chocolate Frosting

• 6 oz (180 g) semisweet or bittersweet chocolate, chopped
• 1 cup unsalted butter (226 g), softened
• 2 cups powdered sugar (230 g), sifted

Instructions

1. Prepare the Pans

Preheat the oven to 350°F (175°C). Grease two 9-inch round cake pans and line the bottoms with parchment paper.

2. Mix the Dry Ingredients

In a large bowl, whisk together the sugar, flour, cocoa powder, baking powder, baking soda, and salt until evenly combined.

3. Add the Wet Ingredients

Add the eggs, warm water or coffee, milk, oil, and vanilla extract. Whisk until the batter is smooth. It will be relatively thin.

4. Bake the Cake Layers

Divide the batter evenly between the prepared pans.

Bake for 30–35 minutes, or until a toothpick inserted into the center comes out clean or with a few moist crumbs.

Let the cakes cool in their pans for 10 minutes, then transfer them to wire racks to cool completely.

5. Make the Chocolate Frosting

Melt the chopped chocolate in the microwave in short intervals or over a double boiler. Let it cool until lukewarm but still fluid.

Beat the softened butter until smooth. Gradually add the powdered sugar and beat until creamy. Add the melted chocolate and beat until smooth and fluffy.

6. Assemble the Cake

Place one cake layer on a serving plate and spread frosting over the top. Add the second layer and cover the top and sides with the remaining frosting.

Decorate with chocolate curls or sprinkles if desired. Slice and serve.

Tips for the Best Chocolate Cake

• Use room-temperature ingredients: Eggs and milk combine more easily when they aren’t cold.
• Measure flour accurately: Spoon it into the measuring cup and level it off to avoid a dry cake.
• Use coffee for deeper flavor: Coffee enhances the chocolate taste without making the cake taste strongly of coffee.
• Don’t overmix: Whisk until the ingredients are combined to keep the crumb tender.
• Avoid overbaking: Start checking for doneness at 30 minutes.
• Cool completely before frosting: Warm cake layers can melt the frosting.

Easy Chocolate Cake Variations

• Mocha cake: Use brewed coffee instead of water and add 1 teaspoon of espresso powder.
• Chocolate raspberry cake: Spread a thin layer of raspberry jam between the cake layers.
• Double chocolate cake: Fold chocolate chips into the batter before baking.
• Salted chocolate cake: Finish the frosted cake with a small pinch of flaky sea salt.

How to Store Chocolate Cake

Room temperature: Store in an airtight container for up to 2 days in a cool environment.

Refrigerator: Store covered for up to 5 days. Let slices sit at room temperature before serving for a softer texture.

Freezer: Wrap unfrosted cake layers tightly in plastic wrap and foil, then freeze for up to 2 months. Thaw before frosting.

You can also freeze frosted slices in an airtight container. Thaw in the refrigerator before serving.

Common Chocolate Cake Problems

Frequently Asked Questions

Can I use Dutch-process cocoa powder?

Yes, but the cake’s rise and texture may vary depending on the cocoa powder and its acidity. Natural unsweetened cocoa is a reliable choice for this recipe because it works well with the baking soda.

How do I keep this chocolate cake moist?

The oil and milk help keep the cake moist. Using warm coffee or water also helps incorporate the cocoa. Avoid overbaking, and store the cooled cake in an airtight container.

Can I turn this recipe into cupcakes?

Yes. Divide the batter among approximately 24 lined cupcake wells, filling each about two-thirds full. Bake at 350°F (175°C) for about 18–22 minutes, checking for doneness with a toothpick.

Can I make the frosting without chopped chocolate?

Yes. For a simpler cocoa frosting, use a suitable chocolate buttercream recipe made with butter, powdered sugar, cocoa powder, and a little milk. The texture and flavor will differ from the original frosting.

How do I get evenly sized cake layers?

Divide the batter evenly between the two pans, ideally using a kitchen scale. This helps both layers bake at a similar rate.

Can I make this cake ahead of time?

Yes. Bake the cake layers a day ahead, let them cool completely, wrap them tightly, and refrigerate. Frost the cake when you’re ready to serve.
