Ingredients for Chocolate Cake Recipe with Cocoa Powder
Here’s everything you’ll need to make this delicious cake.
- 2 cups granulated sugar
- 1¾ cups all-purpose flour
- ¾ cup unsweetened cocoa powder
- 1½ teaspoons baking powder
- 1½ teaspoons baking soda
- 1 teaspoon salt
- 2 large eggs
- 1 cup milk
- ½ cup vegetable oil
- 2 teaspoons vanilla extract
- 1 cup boiling water
Ingredient Notes
Cocoa Powder
Use unsweetened natural cocoa powder for a classic chocolate flavor. Dutch-processed cocoa can be used, but the cake may rise slightly differently due to acidity changes.
Milk Substitutions
You can use whole milk, 2%, or even dairy-free alternatives like almond or oat milk.
Oil Options
Vegetable oil keeps the cake moist. You may substitute with canola oil or melted coconut oil (cooled slightly before mixing).
Boiling Water
This step may seem unusual, but it helps bloom the cocoa powder and creates a smooth, thin batter that bakes into a moist cake. Some bakers use hot brewed coffee instead of water to enhance chocolate depth (the cake will not taste like coffee).
Step-by-Step Instructions
Step 1 – Prepare the Oven and Pans
Preheat your oven to 350°F (175°C). Grease and flour two 9-inch round cake pans. For extra chocolate flavor and no white coating, you can dust the pans with cocoa powder instead of flour.
Step 2 – Mix the Dry Ingredients
In a large mixing bowl, add the sugar, flour, cocoa powder, baking powder, baking soda, and salt. Stir everything together until evenly combined.
Step 3 – Add the Wet Ingredients
Add the eggs, milk, vegetable oil, and vanilla extract to the bowl. Using a hand mixer or whisk, beat the mixture for about 2 minutes until smooth and well blended.
Step 4 – Stir in the Boiling Water
Carefully pour in the boiling water while stirring slowly. The batter will become very thin — this is completely normal. The thin batter is what creates the moist, tender crumb.
Step 5 – Bake the Cake
Divide the batter evenly between the prepared pans. Bake for 30–35 minutes, or until a toothpick inserted in the center comes out clean.
Step 6 – Cool Completely
Allow the cakes to cool in the pans for 10 minutes. Then remove them from the pans and transfer to a wire rack to cool completely before frosting.
Pro Tips for Success
- Measure Flour Correctly
Spoon flour into your measuring cup and level it off. Scooping directly can pack too much flour and make the cake dense. - Don’t Skip the Boiling Water
It may seem odd, but it’s essential for moisture and texture. - Avoid Overbaking
Check at 30 minutes. Overbaking dries out the cake quickly. - Use Room Temperature Eggs
They mix more evenly and help create a smoother batter. - Cool Before Frosting
Frosting warm cake can cause melting and sliding layers.
Flavor Variations
This chocolate cake recipe with cocoa powder is wonderfully versatile.
Chocolate Buttercream Layer Cake

Mocha Style
Replace boiling water with hot coffee for deeper flavor.
Cupcakes
Bake in lined muffin tins for 18–22 minutes.
Serving Suggestions

FAQ About Chocolate Cake Recipe with Cocoa Powder
Why is the batter so thin?
The thin batter comes from adding boiling water. This helps dissolve the cocoa powder fully and creates a moist, soft texture after baking. Don’t worry — it bakes up perfectly.
Can I use butter instead of oil?
Yes, you can substitute melted butter for oil. However, oil tends to produce a more moist cake. Butter will add a slightly richer flavor but may result in a slightly firmer crumb.
Can I make this cake in a 9×13 pan?
Absolutely. Pour the batter into a greased 9×13-inch baking pan and bake for about 35–40 minutes. Check with a toothpick for doneness.
How do I make this cake more chocolatey?
You can replace the boiling water with hot brewed coffee to intensify the chocolate flavor. Adding a handful of mini chocolate chips to the batter is another great option.
Can I make it dairy-free?
Yes. Substitute milk with almond milk, oat milk, or soy milk. The texture remains soft and delicious.
Why did my cake sink in the middle?
Common reasons include opening the oven door too early, underbaking, or expired baking soda or baking powder. Always check freshness of leavening agents before baking.
