- Perfectly Baked, Super Moist Cake: The chocolate cake bakes flawlessly every single time, ensuring a super moist crumb that is rich in flavor. You’ll never have to worry about dry cake again! Furthermore, the recipe is designed so that the cake effortlessly releases from the pans, making your baking experience stress-free.

How To Make This Amazing Chocolate Cake With Chocolate Buttercream Frosting
Creating this impressive two-layer chocolate cake and its heavenly frosting from scratch is surprisingly simple. Just follow these easy steps to bake your way to chocolate perfection:
Baking the Moist Chocolate Cake Layers:
- Preheat Oven: Begin by preheating your oven to 350 degrees F (175 degrees C). This ensures the oven is at the correct temperature when your batter is ready, promoting even baking.
- Prepare Cake Pans: Prepare two 9-inch round cake pans. You can do this by generously greasing them with butter or cooking spray, then dusting with flour or cocoa powder. For an extra layer of assurance against sticking, line the bottoms with parchment paper. This step is crucial for easy release.
- Combine Dry Ingredients: In a large mixing bowl, whisk together all the dry ingredients: all-purpose flour, unsweetened cocoa powder, sugar, baking powder, baking soda, and salt. Whisking ensures they are well combined and evenly distributed.
- Add Wet Ingredients (Except Hot Water): To the dry ingredients, add the eggs, vanilla extract, vegetable oil, and milk. Mix these ingredients thoroughly until just combined. Be careful not to overmix, as this can lead to a tough cake.
- Incorporate Hot Water: Gradually add the hot water (or freshly brewed hot coffee for an even deeper chocolate flavor) to the cake batter while continuously mixing. The hot liquid helps to bloom the cocoa powder, intensifying its flavor and contributing to the cake’s moist texture. Mix until the batter is smooth and well combined, but again, avoid overmixing.
- Divide and Bake: Evenly divide the prepared batter between your two greased and floured (or parchment-lined) cake pans. Gently tap the pans on the counter a few times to release any trapped air bubbles. Bake for approximately 28-30 minutes, or until a wooden skewer or toothpick inserted into the center of a cake comes out clean.
- Cool Completely: Allow the cakes to cool in their pans on a wire rack for about 10-15 minutes before inverting them onto the rack to cool completely. It’s absolutely essential that the cakes are entirely cool before you even think about frosting them. Warm cakes will cause your beautiful buttercream to melt and slide off!
Crafting the Fluffy Chocolate Buttercream Frosting:
While your cake layers are cooling, you can prepare the exquisite chocolate buttercream frosting. This frosting is the perfect balance of richness and airiness, making it ideal for piping and spreading:
- Beat Butter: In a large mixing bowl (preferably using a stand mixer with a paddle attachment), beat the softened unsalted butter on medium-high speed until it becomes incredibly smooth, light, and creamy. This usually takes about 2-3 minutes. Proper creaming of the butter is key to a fluffy frosting.
- Add Remaining Ingredients: Gradually add the unsweetened cocoa powder, vanilla extract, milk, and powdered sugar to the butter. Start mixing on low speed to prevent the powdered sugar from flying everywhere, then increase to medium-high speed.
- Whip to Perfection: Continue to mix on high speed for 3-4 minutes, or until the buttercream is wonderfully light, airy, and fluffy. Scrape down the sides of the bowl occasionally to ensure all ingredients are fully incorporated. The longer you beat it, the lighter and fluffier it will become.
- Frost and Enjoy: Once your cake layers are completely cool and your buttercream is ready, it’s time to assemble and frost your masterpiece! Spread the chocolate buttercream evenly between the layers and all over the top and sides of the cake.
What Other Delicious Ingredients Can I Decorate This Cake With?
While fresh blueberries and mint provide a classic, elegant finish, this versatile chocolate cake welcomes a variety of delicious decorations to suit any occasion or preference. Get creative and make it your own!
- Raspberries: Their tartness beautifully cuts through the sweetness of the chocolate. Arrange them artfully on top or around the base.
- Strawberries: Fresh, ripe strawberries add a burst of color and a lovely fruity flavor that pairs wonderfully with chocolate. Sliced or whole, they always look inviting.
- Blackberries: These dark, juicy berries offer a sophisticated touch and a slightly more intense berry flavor.
- Rainbow Sprinkles: Perfect for birthdays or any festive occasion, rainbow sprinkles instantly add a pop of color and a playful texture.
- Chocolate Sprinkles: For the ultimate chocolate lover, a generous dusting of chocolate sprinkles (or chocolate shavings/curls) intensifies the chocolate experience and adds a delightful textural contrast.
- Edible Flowers: For a truly elegant and gourmet presentation, a few carefully placed edible flowers can transform your cake into a work of art.
- Toasted Coconut Flakes: Add a tropical twist and a satisfying crunch.
- Caramel Drizzle: A luscious caramel sauce drizzled over the top adds another layer of indulgence and flavor.
What Are the Best Serving Suggestions for This Chocolate Cake?
This decadent chocolate cake is a treat in itself, but pairing it with the right beverage or accompaniment can elevate the entire experience. Here are some highly recommended ways to enjoy your slice of chocolate heaven:
- Coffee or Espresso: The rich, slightly bitter notes of a freshly brewed cup of coffee or a strong espresso create a classic and incredibly satisfying pairing with chocolate. It’s the perfect pick-me-up.
- Tea: For a more refined experience, a warm cup of black tea (like Earl Grey or English Breakfast) or even a fragrant herbal tea can beautifully complement the cake without overpowering its flavor.
- Cold Glass of Milk: There’s something undeniably comforting and classic about a tall, cold glass of milk with chocolate cake. It’s a simple pairing that truly “seals the deal” for many.
- Vanilla Ice Cream: As mentioned, a warmed slice of cake with a scoop of premium vanilla bean ice cream is a luxurious combination, creating a delightful hot-and-cold sensation.
- Fresh Berries: A side of fresh raspberries or sliced strawberries can add a refreshing tartness that cleanses the palate and brightens the chocolate flavor.
Choosing the Right Cocoa Powder for Your Chocolate Cake
The quality of your cocoa powder can significantly impact the flavor and color of your chocolate cake and buttercream. For this recipe, you absolutely want to use a high-quality, unsweetened cocoa powder. I recommend using the same type of cocoa powder for both the cake batter and the chocolate buttercream to ensure a consistent and harmonious flavor profile.
- Natural Unsweetened Cocoa Powder: This type of cocoa powder is acidic and reacts with baking soda to create lift in baked goods. It typically has a lighter color and a sharper, fruitier chocolate flavor.
- Dutch-Processed Cocoa Powder: This cocoa powder has been treated with an alkali to neutralize its acidity. It results in a darker color and a smoother, milder, less bitter chocolate flavor. Because it’s not acidic, it usually requires baking powder (or a combination of baking powder and a smaller amount of baking soda) for leavening.
For this specific recipe, either natural or Dutch-processed unsweetened cocoa powder will work, but using a good quality brand will truly make a difference in the depth of chocolate flavor. Look for brands that specify “premium” or “gourmet” for the best results. The richer the cocoa, the more decadent your cake will taste!
How Long Will This Homemade Chocolate Cake Last For?
Proper storage is key to maintaining the freshness and deliciousness of your homemade chocolate cake. Here’s how to ensure it stays delightful for as long as possible:
- Room Temperature: If properly stored in an airtight container at room temperature, this cake can remain fresh and delicious for up to 3 days. This is often the best way to store frosted cakes, as the frosting helps to seal in moisture, and the cake’s texture is generally best at room temperature.
- Refrigerated: For longer storage, you can refrigerate the cake. When stored in an airtight container in the refrigerator, it can last up to 1 week. However, keep in mind that refrigeration can sometimes alter the texture of the cake, making it slightly firmer.
- Serving Recommendation: For the absolute best flavor and texture, I highly recommend allowing the cake to come to room temperature for at least 30-60 minutes before serving, even if it has been refrigerated. This allows the butter in the frosting to soften and the cake layers to regain their moist, tender crumb.
- Freezing: You can also freeze individual slices or whole cake layers for even longer storage. Wrap tightly in plastic wrap and then aluminum foil to prevent freezer burn. It can be frozen for up to 2-3 months. Thaw in the refrigerator overnight before bringing to room temperature to serve.

- 3/4 cup unsweetened cocoa powder
- 2 cups sugar
- 2 tsp baking powder
- 1 1/2 tsp baking soda
- 1 tsp salt
- 2 eggs
- 1/2 cup vegetable oil
- 1 cup milk
- 1 cup boiling water
- 2 tsp vanilla extract
Chocolate Buttercream
- 12 ounces unsalted butter
- 1 cup unsweetened cocoa powder
- 5 cups powdered sugar
- 1/2 cup milk
- 2 tsp vanilla extract
Instructions
-
Preheat oven to 350 degrees F (175 degrees C). This ensures the oven is at the correct temperature for even baking from the start.
-
Prepare two 9-inch round cake pans by thoroughly greasing them with butter or cooking spray, then dusting with flour or cocoa powder. For extra non-stick assurance, you may also line the bottoms with parchment paper.
-
In a large bowl, sift together the unsweetened cocoa powder, all-purpose flour, baking soda, baking powder, and salt. Sifting helps to remove any lumps and ensures a light, airy cake texture. Set this dry mixture aside.
-
In a separate, medium-sized bowl, combine the wet ingredients: eggs, vegetable oil, milk, sugar, and vanilla extract. Whisk them until they are well blended.
-
Gradually add the wet mixture to the dry flour mixture, stirring until just combined. Then, slowly pour in the boiling water (or hot coffee), mixing gently until the batter is smooth and uniform. Be careful not to overmix, which can develop gluten and lead to a tough cake.
-
Divide the cake batter evenly between the two prepared pans. Gently tap the pans on the counter a few times to release any large air bubbles, promoting an even bake.
-
Bake the cakes for approximately 28-30 minutes, or until a wooden skewer or toothpick inserted into the center comes out clean. The exact baking time may vary slightly depending on your oven.
-
Allow the cakes to cool completely in their pans on a wire rack for about 10-15 minutes before inverting them onto the rack to finish cooling. It’s crucial for the cakes to be entirely cool before frosting to prevent melting.
-
To make the frosting: In a large bowl with an electric mixer (stand mixer preferred), beat the softened unsalted butter until smooth and creamy. Then, gradually add the cocoa powder, powdered sugar, milk, and vanilla extract.
-
Mix on medium-high speed for about 3-4 minutes, or until the buttercream is wonderfully light, airy, and fluffy. Scrape down the sides of the bowl as needed to ensure all ingredients are well incorporated.
-
Once the cakes are completely cool, frost them generously with the fluffy chocolate buttercream. Decorate as desired with fresh fruit or sprinkles, then slice and enjoy your magnificent homemade chocolate cake!
