Ingredients

• 2 cups white sugar
• 1 ¾ cups all-purpose flour
• ¾ cup unsweetened cocoa powder
• 1 ½ teaspoons baking powder
• 1 ½ teaspoons baking soda
• 1 teaspoon salt
• 2 large eggs
• 1 cup milk
• ½ cup vegetable oil
• 2 teaspoons vanilla extract
• 1 cup boiling water

How to Make One Bowl Chocolate Cake

1. Prepare the Oven and Pan

Preheat your oven to 350°F (175°C).

Grease a 9×13-inch baking pan and lightly dust it with flour or cocoa powder. You can also line the bottom with parchment paper for easier removal.

2. Combine the Dry Ingredients

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

Make sure the cocoa powder is evenly distributed and break up any large lumps.

3. Add the Wet Ingredients

Add the eggs, milk, vegetable oil, and vanilla extract directly to the same bowl.

Whisk until the ingredients are well combined and the batter is smooth.

There’s no need to overmix. Once the flour has been incorporated, stop mixing.

4. Add the Boiling Water

Slowly pour the boiling water into the batter while whisking gently.

The batter will become quite thin. Don’t worry—this is exactly what you want. The extra liquid helps create a soft and moist chocolate cake.

5. Bake

Pour the batter into the prepared pan and spread it evenly.

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

Avoid overbaking, as this can make the cake less tender.

6. Cool and Serve

Remove the cake from the oven and place it on a wire rack.

Let it cool in the pan for at least 20–30 minutes before slicing.

You can serve it as-is, dust it with powdered sugar, or add your favorite chocolate frosting.

Recipe Tips for Success

Measure the Flour Correctly

For the best texture, spoon the flour into your measuring cup and level it with the back of a knife. Scooping directly from the flour bag can pack too much flour into the cup.

Don’t Skip the Boiling Water

The boiling water helps hydrate the cocoa powder and creates a smoother, softer cake batter. It also contributes to the cake’s moist texture.

Don’t Overmix

Mix just until the ingredients are combined. Overmixing can develop too much gluten and make the cake less tender.

Use Fresh Leavening Agents

Baking powder and baking soda help the cake rise. If they have been sitting in your pantry for a long time, check that they are still fresh.

Let the Cake Cool

Allow the cake to cool before frosting or slicing. This gives the crumb time to set and makes cleaner slices.

Ingredient Substitutions

Milk: Whole milk, 2% milk, or another regular dairy milk can be used.

Vegetable Oil: Canola oil or another neutral-flavored oil works well.

Eggs: Use large eggs at room temperature when possible.

Boiling Water: Hot coffee can replace the boiling water if you want an even deeper chocolate flavor.

Cocoa Powder: Use unsweetened cocoa powder rather than sweetened drinking chocolate.

How to Store

Store leftover cake in an airtight container at room temperature for up to 3 days.

If the cake is frosted with a perishable frosting, refrigerate it and allow it to sit at room temperature for a short time before serving.

Can You Freeze One Bowl Chocolate Cake?

Yes. This cake freezes well.

Allow the cake to cool completely, then wrap individual slices or the whole unfrosted cake tightly in plastic wrap. Place it in a freezer-safe container or bag.

Freeze for up to 3 months.

Thaw the cake in the refrigerator overnight or at room temperature for several hours before serving.

Frequently Asked Questions

Why is my chocolate cake batter so thin?

The boiling water adds a significant amount of liquid to the batter. This is intentional and helps produce a moist, tender cake.

Can I use coffee instead of boiling water?

Yes. Strong hot coffee can replace the boiling water in an equal amount. Coffee enhances the chocolate flavor without necessarily making the cake taste like coffee.

Can I make this cake without frosting?

Absolutely. The cake is flavorful enough to serve on its own. A light dusting of powdered sugar is an easy finishing touch.

Can I make this chocolate cake in round pans?

Yes. You can divide the batter between two 9-inch round cake pans. Begin checking the cakes around 25–30 minutes, as baking time may vary depending on your pans and oven.

How do I know when the cake is done?

Insert a toothpick into the center. It should come out clean or with a few moist crumbs attached. If there is wet batter on the toothpick, continue baking for a few more minutes.

Can I make this cake ahead of time?

Yes. The cake can be baked a day ahead. Once completely cooled, cover it tightly and store it until you’re ready to frost and serve.
