The Ultimate Chocolate Cake with Decadent Chocolate Buttercream Frosting

Few desserts rival the timeless appeal of a chocolate cake. Perfect for birthdays, celebrations, or just a sweet indulgence, this recipe for a moist chocolate cake with creamy chocolate buttercream frosting is bound to impress. With step-by-step instructions, you’ll be baking like a pro in no time.

Ingredients

For the Cake:

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

For the Chocolate Buttercream Frosting:

1 cup unsalted butter, softened
3 ½ cups powdered sugar
½ cup unsweetened cocoa powder
½ teaspoon salt
2 teaspoons vanilla extract
¼ cup heavy cream

Instructions

Prepare for Baking

Preheat your oven to 350°F (175°C).
Grease and flour two 9-inch round cake pans or line them with parchment paper for easy removal.

Make the Cake

Step 1: Mix Dry Ingredients

In a large bowl, whisk together flour, cocoa powder, sugar, baking powder, baking soda, and salt until well combined.

Step 2: Combine Wet Ingredients

In a separate bowl, whisk together eggs, milk, vegetable oil, and vanilla extract.
Slowly add the wet mixture to the dry ingredients, stirring until just combined.

Step 3: Add Boiling Water

Gradually pour in the boiling water, mixing until the batter is smooth. (The batter will be thin—this is normal!)

Step 4: Bake

Divide the batter evenly between the prepared pans.
Bake for 30–35 minutes, or until a toothpick inserted in the center comes out clean.
Cool cakes in the pans for 10 minutes before transferring them to a wire rack to cool completely.

Make the Frosting

Step 1: Cream the Butter

Beat softened butter in a large bowl with an electric mixer on medium speed until light and fluffy (about 3–4 minutes).

Step 2: Add Dry Ingredients

Sift powdered sugar, cocoa powder, and salt together. Gradually add this mixture to the butter, beating on low speed.

Step 3: Add Vanilla and Cream

Add vanilla extract and heavy cream. Increase the mixer speed to medium-high and beat until the frosting is smooth and spreadable.
If the frosting is too thick, add cream one tablespoon at a time.

Assemble the Cake

Level the Layers
- Use a serrated knife to level the tops of the cakes for easier stacking.
Frost the Layers
- Place one cake layer on a serving plate. Spread a generous amount of frosting over the top.
Add the Second Layer
- Place the second layer on top and press gently. Spread a thin crumb coat over the entire cake, then refrigerate for 20 minutes.
Finish Frosting
- Cover the cake completely with the remaining frosting. Smooth the sides with an offset spatula or create decorative swirls for texture.

Serving Suggestions

Decorate: Garnish with chocolate shavings, sprinkles, or fresh berries.
Pair It: Serve with vanilla ice cream or whipped cream for added indulgence.
Store It: Keep at room temperature for up to 2 days or refrigerate for up to a week.

Tips for Success

Room-Temperature Ingredients: Use room-temperature eggs and milk for the best texture.
Sift Dry Ingredients: Prevent lumps by sifting the flour and cocoa powder.
Avoid Overmixing: Stir just until ingredients are combined to keep the cake light and fluffy.

Why This Recipe Stands Out

This cake combines rich, chocolatey layers with velvety buttercream frosting for the ultimate dessert experience. Moist, tender, and decadent, it’s perfect for special occasions or whenever you need a chocolate fix.

Final Thoughts

Baking this chocolate cake is easier than you think, and the results are well worth the effort. Whether you’re celebrating a milestone or indulging in a sweet treat, this foolproof recipe is sure to delight. Enjoy the rich flavors and the smiles it brings to the table!
