Ingredients
Chocolate Cake
| Ingredient | Quantity |
| Large eggs, room temperature | 5 |
| Granulated sugar | 1 cup |
| All-purpose flour | 1½ cups |
| Unsweetened cocoa powder | ½ cup |
| Whole milk | ½ cup |
| Baking powder | 1 tablespoon |
| Dark chocolate chunks or chopped chocolate | ½ cup |

Best Ingredient Options
Eggs
Use large eggs at room temperature. Room-temperature eggs generally incorporate more easily into the batter.
Cocoa Powder
Use good-quality unsweetened cocoa powder for a richer chocolate flavor.
Dark Chocolate
Dark chocolate chunks provide little pockets of melted chocolate throughout the cake.
For a smoother texture, melt the chocolate and incorporate it into the batter instead.
Milk
Whole milk gives the cake a richer texture. You can use another type of milk, although the final texture may vary slightly.
Powdered Sugar
Powdered sugar provides a simple and elegant finish. Dust it over the completely cooled cake immediately before serving.
How to Make Classic One-Bowl Chocolate Cake
Prepare the Oven
Preheat your oven to 350°F (175°C).
Line the bottom of an 8-inch or 9-inch round cake pan with parchment paper.
Lightly grease the sides of the pan.
For the most consistent baking, place the oven rack in the center position.
Combine the Eggs and Sugar
Add the eggs and granulated sugar to a large mixing bowl.
Whisk until the mixture is well combined and slightly lighter in appearance.
There is no need to whip the eggs to stiff peaks, but mixing thoroughly helps create a uniform batter.
Add the Dry Ingredients
Sift the all-purpose flour, cocoa powder, and baking powder into the bowl.
Sifting helps break up cocoa lumps and distributes the leavening ingredients more evenly throughout the flour.
Add the Milk
Pour in the whole milk.
Whisk gently until the ingredients are incorporated and the batter is smooth.
Avoid excessively vigorous mixing once the flour has been added, as overmixing can make the finished cake less tender.
Add the Chocolate
If using chocolate chunks, gently fold them into the batter with a spatula.
For a smoother chocolate cake, melt the dark chocolate first and allow it to cool slightly before incorporating it into the batter.
Do not add extremely hot melted chocolate directly to the eggs.
Fill the Cake Pan
Pour the batter into the prepared cake pan.
Use a spatula to gently smooth the surface.
Tap the pan lightly on the countertop once or twice to help release large trapped air bubbles.
Bake
Place the pan in the center of the preheated oven.
Bake for approximately 35–40 minutes.
Start checking around the 35-minute mark because oven temperatures and cake-pan sizes can affect baking time.
The cake should look set and slightly domed.
Insert a toothpick into the center. It should come out clean or with a few moist crumbs attached.
Cool the Cake
Remove the cake from the oven and allow it to cool in the pan for approximately 10 minutes.
Carefully loosen the edges with a thin knife or spatula.
Turn the cake onto a wire rack and allow it to cool completely.
Add the Powdered Sugar
Once completely cool, place the cake on a serving plate.
Use a fine-mesh sieve to lightly dust the top with powdered sugar.
For an especially attractive presentation, dust the sugar immediately before serving.
Slice and Serve
Cut the cake into generous wedges.
Serve at room temperature with coffee, tea, milk, whipped cream, berries, or your favorite dessert topping.
Best Baking Tips
Use room-temperature eggs. They mix more easily with the other ingredients.
Sift the cocoa powder. Cocoa can easily form lumps, so sifting helps create a smoother batter.
Don’t overmix. Once the flour is incorporated, mix only until the batter is smooth.
Measure flour carefully. Too much flour can produce a dry or dense cake.
Don’t open the oven too early. Opening the oven repeatedly during the first part of baking can interfere with the cake’s rise.
Check with a toothpick. Baking time can vary between ovens, so use visual cues and a toothpick test rather than relying only on the clock.
Cool completely before dusting. If the cake is warm, powdered sugar can melt into the surface.
Recipe Variations
Chocolate Ganache Cake
Allow the cake to cool completely, then pour a simple chocolate ganache over the top.
Let the ganache set slightly before slicing.
Chocolate Cream Cake
Slice the cooled cake horizontally and fill it with lightly sweetened whipped cream.
Add fresh strawberries or raspberries for a fresh contrast.
Double Chocolate Cake
Add additional chocolate chunks to the batter for a richer, more indulgent chocolate dessert.
Mocha Chocolate Cake
Add a small amount of instant espresso powder to intensify the chocolate flavor.
Chocolate Berry Cake
Serve individual slices with fresh strawberries, raspberries, or blueberries and a spoonful of whipped cream.
Frosted Chocolate Cake
Top the completely cooled cake with chocolate buttercream, cream cheese frosting, or your favorite chocolate frosting.
What to Serve With Chocolate Cake
Fresh Berries
Strawberries, raspberries, and blueberries provide a fresh contrast to the rich chocolate cake.
Whipped Cream
A spoonful of lightly sweetened whipped cream makes the cake feel extra special without overwhelming its chocolate flavor.
Vanilla Ice Cream
Serve a warm or room-temperature slice with a scoop of vanilla ice cream for a classic dessert combination.
Coffee
The deep flavor of coffee pairs beautifully with chocolate cake.
Chocolate Sauce
For an extra indulgent dessert, drizzle each slice with warm chocolate sauce.
Make-Ahead Instructions
This cake is an excellent make-ahead dessert.
Bake the cake according to the recipe and allow it to cool completely.
Once cooled, wrap it tightly or place it in an airtight container.
Keep it at room temperature if serving within a short period, or refrigerate it if you need to store it longer.
Add powdered sugar shortly before serving for the best appearance.
Storage
Store the cooled cake in an airtight container.
At room temperature, it is best enjoyed within approximately 2–3 days.
For longer storage, refrigerate the cake for up to approximately 5 days.
If refrigerated, allow individual slices to sit at room temperature for a short time before serving for the best texture.
Freezing Instructions
This chocolate cake can be frozen.
Allow the cake to cool completely before wrapping it tightly in plastic wrap and placing it inside a freezer-safe container or bag.
Freeze for up to approximately 2–3 months for best quality.
Thaw overnight in the refrigerator or allow individual slices to thaw at room temperature.
Add powdered sugar after thawing rather than before freezing.
Reheating
Individual slices can be gently warmed in the microwave for a few seconds.
Avoid overheating, as this can dry out the cake.
A slightly warmed slice pairs especially well with vanilla ice cream or whipped cream.
Common Mistakes to Avoid
Using cold eggs: Very cold eggs can be more difficult to incorporate smoothly.
Adding too much flour: Excess flour can make the cake dry.
Overmixing the batter: Too much mixing after adding flour can result in a tougher crumb.
Using hot melted chocolate: Extremely hot chocolate can negatively affect the egg mixture. Let melted chocolate cool slightly before adding it.
Overbaking: A few extra minutes in the oven can make a chocolate cake noticeably drier.
Dusting powdered sugar too early: Add it only after the cake has cooled completely.
Cutting immediately: Allow the cake to cool before slicing so the crumb can set properly.

Frequently Asked Questions
Can I use an 8-inch or 9-inch cake pan?
Yes. Both sizes work. An 8-inch pan will produce a slightly taller cake, while a 9-inch pan will produce a slightly thinner cake and may require a little less baking time.
Can I use milk chocolate instead of dark chocolate?
Yes. Milk chocolate will create a sweeter and milder chocolate flavor.
Why did my cake sink in the middle?
A cake can sink if it is underbaked, the oven temperature is inaccurate, or the oven door is opened too early during baking.
Make sure the center is properly set before removing the cake from the oven.
How can I make the cake more chocolatey?
Use high-quality cocoa powder and dark chocolate. You can also add a small amount of espresso powder to intensify the chocolate flavor.
Can I frost this cake?
Absolutely. Chocolate buttercream, chocolate ganache, vanilla frosting, and cream cheese frosting all work beautifully.
Can I make cupcakes with this batter?
The batter can be adapted for cupcakes, but the baking time will be significantly shorter. Begin checking them early and use a toothpick to determine when they are done.
