Balanced sweetness
Smooth, creamy frosting
Beautiful presentation

Ingredients

For the Chocolate Cake Layers:

2 cups all-purpose flour
2 cups granulated sugar
¾ cup unsweetened cocoa powder (high quality recommended)
2 teaspoons baking powder
1 teaspoon baking soda
½ teaspoon salt
2 large eggs (room temperature)
1 cup whole milk (room temperature)
½ cup vegetable oil
2 teaspoons pure vanilla extract
1 cup hot water or hot brewed coffee

For the Chocolate Buttercream Frosting:

1 cup unsalted butter (softened)
3 to 3½ cups powdered sugar
½ cup unsweetened cocoa powder
¼ cup heavy cream or milk
2 teaspoons vanilla extract
Pinch of salt

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.
Line the bottoms with parchment paper for easy removal.

Proper preparation ensures your cake releases cleanly and bakes evenly.

Step 2: Mix the Dry Ingredients

In a large mixing bowl, whisk together:

Flour
Sugar
Cocoa powder
Baking powder
Baking soda
Salt

Make sure everything is evenly combined to avoid lumps.

Step 3: Add the Wet Ingredients

Add:

Eggs
Milk
Vegetable oil
Vanilla extract

Using an electric mixer, beat on medium speed for about 2 minutes. The batter will start to become smooth and slightly thick.

Step 4: Add the Hot Liquid

Slowly pour in the hot water or coffee while mixing on low speed.

The batter will become thin — this is completely normal. The hot liquid “blooms” the cocoa powder, intensifying the chocolate flavor and creating an ultra-moist cake.

Step 5: Bake the Cake

Divide the batter evenly between the prepared pans.
Bake for 30–35 minutes.
Check doneness by inserting a toothpick into the center — it should come out clean or with a few moist crumbs.

Let the cakes cool in the pans for 10 minutes, then transfer to a wire rack to cool completely before frosting.

Making the Chocolate Buttercream

Step 1: Cream the Butter

Beat the softened butter on medium speed for 2–3 minutes until light and fluffy.

Step 2: Add Dry Ingredients

Gradually add:

Cocoa powder
Powdered sugar

Mix on low speed first to avoid a sugar cloud, then increase speed.

Step 3: Add Cream and Vanilla

Add:

Heavy cream
Vanilla extract
Pinch of salt

Beat for another 2–3 minutes until smooth, creamy, and spreadable.

If too thick → add 1 tablespoon of cream.
If too thin → add more powdered sugar.

Assembling the Cake

Place one cake layer on a serving plate.
Spread an even layer of buttercream on top.
Add the second layer.
Apply a thin “crumb coat” of frosting and chill for 15–20 minutes.
Finish with a final smooth layer of frosting.

For a bakery-style finish, use an offset spatula or bench scraper.

Optional Decorations

To truly make this a “Blue Ribbon” cake, try:

Chocolate shavings
Chocolate ganache drip
Fresh berries
Sprinkles or edible gold dust
Piped rosettes
