This blog will walk you through the process of making a mouthwatering chocolate cake from scratch and decorating it with flair. Whether it's for a loved one or yourself, you'll be proud of your homemade creation.
Step 1: Gather Your Ingredients
Before you begin, make sure you have all the necessary ingredients. For the cake itself, you will need:
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 cups granulated sugar
2 large eggs
1 cup whole milk
½ cup vegetable oil
2 teaspoons vanilla extract
1 cup boiling water
For the frosting, here’s what you’ll need:
1 cup unsalted butter, softened
3 ½ cups powdered sugar
½ cup unsweetened cocoa powder
1 teaspoon vanilla extract
¼ cup heavy cream (or milk for a lighter texture)
You’ll also need tools like mixing bowls, a whisk or electric mixer, spatula, and two 9-inch round cake pans.
Step 2: Prepare Your Cake Pans
Begin by preheating your oven to 350°F (175°C). Grease and flour your cake pans or line them with parchment paper. This step ensures that your cakes don’t stick to the pans, making it easy to remove them later.
Step 3: Mix the Dry Ingredients
In a large mixing bowl, sift together the flour, cocoa powder, baking powder, baking soda, and salt. Sifting helps avoid lumps and ensures that all dry ingredients are evenly distributed, which will give your cake a more uniform texture.
Step 4: Mix the Wet Ingredients
In a separate bowl, combine the eggs, sugar, milk, oil, and vanilla extract. Use a whisk or an electric mixer to beat the mixture until it becomes smooth and creamy. This step incorporates air, making the cake lighter.
Step 5: Combine Wet and Dry Ingredients
Slowly add the dry ingredients to the wet ingredients while mixing on low speed or stirring gently. Once everything is combined, gradually add the boiling water to the batter. The batter will be thin, but this is expected. The boiling water will help to intensify the cocoa flavor, giving your cake a richer taste.
Step 6: Pour the Batter and Bake
Pour the batter evenly into the prepared cake pans. Tap the pans gently on the counter to remove any air bubbles. Place the pans in the oven and bake for 30-35 minutes, or until a toothpick inserted in the center comes out clean.
Once baked, remove the cakes from the oven and let them cool in the pans for about 10 minutes. Then, transfer the cakes onto wire racks to cool completely before frosting.
Step 7: Prepare the Chocolate Buttercream Frosting
While your cake cools, you can prepare the frosting. In a mixing bowl, beat the softened butter on medium speed until it becomes creamy and light in color. Gradually add in the powdered sugar and cocoa powder, alternating between the two. Add the vanilla extract and cream, and beat until the frosting becomes smooth and fluffy. If you prefer a thinner consistency, add more cream, one tablespoon at a time.
Step 8: Assemble and Frost the Cake
Once your cake layers have completely cooled, it’s time to assemble. If the cake tops are domed, use a serrated knife to level them off. Place one layer of cake on your serving plate or a cake stand. Spread a generous amount of frosting on top of this layer using an offset spatula or the back of a spoon.
Place the second layer on top and press down gently to ensure it adheres. Spread a thin layer of frosting all over the cake to create a "crumb coat." This seals in any crumbs and ensures that your final layer of frosting is smooth. Refrigerate the cake for 15-20 minutes to set the crumb coat.
Once the crumb coat is set, apply a thicker layer of frosting all over the cake. Use a spatula or butter knife to smooth the sides and top. Don’t worry if it’s not perfect — a homemade cake has its charm!
Step 9: Decorating the Cake
Here comes the fun part: decorating! You can keep it simple or go all out depending on the occasion. Here are a few easy decoration ideas:
Sprinkles: You can never go wrong with sprinkles. After frosting the cake, carefully press sprinkles onto the sides of the cake for a colorful finish. Add more to the top for an extra festive touch.
Chocolate Shavings: Use a vegetable peeler to shave chocolate from a bar onto the top of the cake. The chocolate curls will add an elegant touch to your cake.
Fruit Toppings: Fresh berries like strawberries, raspberries, or cherries can add a pop of color and a fresh flavor contrast to the rich chocolate.
Piping: If you have a piping bag, you can pipe rosettes or stars around the edges of the cake. You don’t need to be a pro at piping—simple patterns can look stunning.
Candy or Cookies: Decorate the top of the cake with chocolate bars, candies, or cookies to add an element of fun, especially for kids’ birthdays.
Step 10: Final Touches and Serving
Once your cake is decorated, refrigerate it for about 30 minutes to allow the frosting to set. This will make slicing easier and give the cake a polished look. When ready to serve, let the cake sit at room temperature for about 10-15 minutes for the best texture.
Bonus Tips for Success
Use Room Temperature Ingredients: For both the cake and frosting, make sure your ingredients, especially eggs and butter, are at room temperature. This ensures that everything blends smoothly, resulting in a lighter cake and creamier frosting.
Leveling the Cake: If your cakes don’t bake evenly, you can use a cake leveler or knife to even them out before stacking. This will make the cake more stable and easier to frost.
Storing the Cake: If you’re not serving the cake right away, store it in an airtight container in the refrigerator. It will stay fresh for up to 3 days. Let it come to room temperature before serving.
