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
- Trim the tops of the cooled cakes if needed for even layers.
- Place one cake layer on a serving plate.
- Spread a generous layer of chocolate buttercream over the top.
- Place the second cake layer on top.
- Cover the entire cake with the remaining frosting.
- 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.
