There’s nothing quite like a classic chocolate cake made from scratch. This recipe creates two tender, deeply chocolatey layers with a soft, moist crumb and a smooth, rich chocolate frosting.
The combination of cocoa powder, brown sugar, buttermilk, and boiling water gives the cake wonderful depth of flavor while keeping the texture soft and tender. Finished with silky semisweet chocolate frosting, it’s the kind of dessert that works beautifully for birthdays, holidays, celebrations, or a simple weekend treat.
🛒 Ingredients
For the Chocolate Cake
- 1¾ cups all-purpose flour
- ¾ cup unsweetened cocoa powder
- 1½ teaspoons baking powder
- 1½ teaspoons baking soda
- 1½ teaspoons salt
- 1 cup granulated sugar
- ¾ cup packed light brown sugar
- ½ cup unsalted butter, at room temperature
- ½ cup vegetable oil
- 2 large eggs
- 2 large egg yolks
- 1 cup buttermilk
- 2 teaspoons vanilla extract
- 1 cup boiling water
For the Chocolate Frosting
- 6 ounces semisweet chocolate, chopped
- ½ cup unsalted butter, at room temperature
- 1½ cups powdered sugar
- ¼ cup heavy cream
- 1 teaspoon vanilla extract
👩🍳 Instructions
1. Prepare the Cake Pans
Preheat your oven to 350°F (175°C). Grease and flour two 9-inch round cake pans. You can also line the bottoms with parchment paper for easier release.
2. Combine the Dry Ingredients
In a medium bowl, whisk together the flour, cocoa powder, baking powder, baking soda, and salt.
Whisking the ingredients together helps distribute the leavening agents and cocoa evenly throughout the cake.
3. Cream the Butter and Sugars
In a large mixing bowl, beat the softened butter, granulated sugar, and brown sugar until light and fluffy.
Add the eggs one at a time, mixing well after each addition. Beat in the egg yolks, followed by the vanilla extract.
4. Add the Flour and Buttermilk
Add the flour mixture and buttermilk alternately to the butter mixture, beginning and ending with the dry ingredients.
Mix just until the batter is combined. Avoid overmixing, as this can make the finished cake less tender.
5. Add the Boiling Water
Slowly stir in the boiling water until the batter becomes smooth.
The batter will be relatively thin, which is completely normal. The hot water helps bring out the cocoa flavor and contributes to the cake’s moist texture.
6. Bake
Divide the batter evenly between the prepared cake pans.
Bake for 25–30 minutes, or until a toothpick inserted into the center comes out clean or with a few moist crumbs attached.
7. Cool the Cake
Allow the cakes to cool in their pans for about 10 minutes.
Carefully invert them onto a wire rack and allow them to cool completely before frosting. Make sure the layers are fully cooled so the frosting doesn’t melt.
🍫 Make the Chocolate Frosting
1. Melt the Chocolate and Butter
Place the chopped semisweet chocolate and butter in a heatproof bowl over a saucepan of gently simmering water.
Stir occasionally until completely melted and smooth. Make sure the bottom of the bowl does not touch the water.
2. Finish the Frosting
Remove the bowl from the heat and allow the mixture to cool slightly.
Beat in the powdered sugar, heavy cream, and vanilla extract until the frosting is smooth, creamy, and spreadable.
If the frosting is too soft, let it cool for a few minutes. If it becomes too firm, allow it to sit at room temperature briefly before spreading.
🎂 Assemble the Cake
Place one completely cooled cake layer on a serving plate.
Spread a generous layer of chocolate frosting over the top. Place the second cake layer on top and cover the top and sides with the remaining frosting.
Decorate with chocolate shavings, chocolate chips, sprinkles, or a few swirls of frosting if desired.
⭐ Tips for the Best Chocolate Cake
Use room-temperature ingredients: Room-temperature butter, eggs, and buttermilk blend more evenly and help create a smoother batter.
Measure flour correctly: Spoon the flour into your measuring cup and level it off rather than scooping directly from the bag.
Don’t overmix: Once the flour is added, mix only until everything is combined.
Don’t worry about thin batter: The boiling water makes the batter thinner than many traditional cake batters. This is expected.
Cool completely before frosting: Warm cake can cause the frosting to soften or slide.
For even layers: Divide the batter as evenly as possible between the two pans.
🍓 Optional Variations
For a delicious twist, add a thin layer of raspberry or strawberry preserves between the cake layers before adding the frosting.
You can also add a teaspoon of espresso powder to the dry ingredients. It won’t make the cake taste like coffee; instead, it can enhance the chocolate flavor.
For an extra-decadent version, sprinkle chopped chocolate, toasted nuts, or chocolate curls over the finished cake.
🧊 Storage
Store the frosted cake in an airtight container at room temperature for up to 2 days, or refrigerate it for several days.
If refrigerated, allow the cake to sit at room temperature for a little while before serving so the frosting and cake can soften.
The unfrosted cake layers can also be wrapped tightly and frozen for longer storage. Thaw completely before decorating.
