Ingredients

For the Chocolate Cake

  • 2 cups (250 g) all-purpose flour
  • 1¾ cups (350 g) granulated sugar
  • ¾ cup (75 g) unsweetened cocoa powder
  • 2 teaspoons baking powder
  • 1½ teaspoons baking soda
  • 1 teaspoon salt
  • 2 large eggs
  • ½ cup (120 ml) vegetable oil
  • 1 cup (240 ml) milk
  • 1 cup (240 ml) hot water or hot coffee
  • 2 teaspoons vanilla extract

For the Chocolate Buttercream Frosting

  • 1 cup (225 g) unsalted butter, softened
  • 3½ cups (440 g) powdered sugar
  • ½ cup (50 g) cocoa powder
  • ¼ cup (60 ml) milk or cream
  • 1 teaspoon vanilla extract

For Decoration

  • Rainbow sprinkles, as needed

Step-by-Step Instructions

Step 1: Prepare the Cake Pans

Preheat your oven to 170°C (340°F). Grease two 8-inch round cake pans and line the bottoms with parchment paper.

Step 2: Mix the Dry Ingredients

In a large mixing bowl, whisk together:

  • Flour
  • Sugar
  • Cocoa powder
  • Baking powder
  • Baking soda
  • Salt

Mix until evenly combined.

Step 3: Add the Wet Ingredients

Add the eggs, vegetable oil, milk, and vanilla extract to the dry mixture. Beat until smooth and fully incorporated.

Step 4: Add the Hot Liquid

Gradually pour in the hot water or hot coffee while mixing gently. The batter will be quite thin, which helps create a moist and tender cake.

Step 5: Bake

Divide the batter evenly between the prepared cake pans.

Bake for 30–35 minutes, or until a toothpick inserted into the center comes out clean.

Step 6: Cool Completely

Allow the cakes to cool in their pans for 10 minutes. Transfer to a wire rack and let them cool completely before frosting.


Make the Chocolate Buttercream

Step 1

In a large bowl, beat the softened butter until light and creamy.

Step 2

Gradually add the powdered sugar and cocoa powder, beating well after each addition.

Step 3

Add the milk (or cream) and vanilla extract.

Step 4

Beat for 3–4 minutes until the frosting becomes smooth, fluffy, and spreadable.


Assemble the Cake

  1. Trim the tops of the cooled cakes if needed for even layers.
  2. Place one cake layer on a serving plate.
  3. Spread a generous layer of chocolate buttercream over the top.
  4. Place the second cake layer on top.
  5. Cover the entire cake with the remaining frosting.
  6. Smooth the sides and top using an offset spatula.

Decorate

Finish the cake with a generous handful of colorful rainbow sprinkles over the top for a fun and festive look.


Pro Tips

✔ Use hot coffee instead of hot water to enhance the chocolate flavor.

✔ Make sure the cake layers are completely cool before frosting.

✔ For extra smooth buttercream, sift the cocoa powder and powdered sugar before mixing.

✔ Chill the cake for 20 minutes after frosting for cleaner slices.
