Ingredients
For the Cake Layers:
- 1 ¾ cups (220 g) all-purpose flour
- 2 cups (400 g) granulated sugar
- ¾ cup (75 g) unsweetened cocoa powder
- 2 teaspoons baking powder
- 1 ½ teaspoons baking soda
- 1 teaspoon salt
- 1 cup (240 ml) buttermilk, at room temperature
- ½ cup (120 ml) vegetable oil
- 2 large eggs, at room temperature
- 2 teaspoons vanilla extract
- 1 cup (240 ml) hot water or hot coffee (coffee enhances chocolate flavor)
For the Chocolate Frosting:
- 1 cup (230 g) unsalted butter, softened
- 3 ½ cups (420 g) powdered sugar

- ½ teaspoon salt
- 2 teaspoons vanilla extract

Optional garnish: chocolate shavings, sprinkles, or fresh berries
Step-by-Step Instructions
Step 1: Prepare Your Oven and Pans
Preheat your oven to 350°F (175°C). Grease and flour two 9-inch round cake pans, or line them with parchment paper circles. This prevents sticking and ensures clean, easy layers.
Step 2: Mix Dry Ingredients
In a large bowl, sift together flour, cocoa powder, sugar, baking powder, baking soda, and salt. Whisk until well combined. This ensures even distribution of leavening agents and cocoa, giving the cake a consistent texture.
Step 3: Combine Wet Ingredients
In a separate bowl, whisk together the buttermilk, vegetable oil, eggs, and vanilla extract until smooth. Gradually add the wet mixture to the dry ingredients, mixing until just combined.
- Tip: Avoid overmixing — overmixing develops gluten and can make the cake dense rather than light and fluffy.
Step 4: Add Hot Water or Coffee
Slowly stir in the hot water or coffee. The batter will be thin — this is normal and helps create a moist, tender cake. Coffee intensifies the chocolate flavor without leaving a noticeable coffee taste.
Step 5: Bake the Cake
Divide the batter evenly between the prepared pans. Bake for 30–35 minutes, or until a toothpick inserted into the center comes out clean or with a few moist crumbs.
Remove from the oven and let the cakes cool in the pans for 10 minutes. Then, transfer to a wire rack to cool completely before frosting.
Step 6: Make the Chocolate Frosting
While the cake cools, prepare the frosting. In a large bowl, beat the softened butter on medium speed until creamy, about 2 minutes. Gradually add the powdered sugar and cocoa powder, beating on low speed at first to prevent a sugar cloud.
Add vanilla, salt, and milk or cream, then beat on medium-high until smooth and fluffy. Adjust consistency by adding more milk for a softer frosting or more powdered sugar for a thicker spread.
Step 7: Assemble the Cake
Once the layers are completely cool, place one cake layer on your serving plate. Spread a generous amount of frosting over the top. Place the second layer on top, then frost the top and sides evenly. Smooth with an offset spatula or leave slightly rustic for a homemade look.
- Optional: Garnish with chocolate shavings, sprinkles, or fresh berries for an elegant touch.
Tips for the Perfect Chocolate Cake
- Room Temperature Ingredients: Using room-temperature eggs and buttermilk ensures better mixing and a lighter crumb.
- Measure Accurately: Proper measuring of flour, sugar, and cocoa powder ensures the cake rises and bakes evenly.
- Don’t Overbake: Slightly underbaked cake will stay moist. Check a few minutes before the timer ends.
- Cool Completely Before Frosting: Frosting a warm cake can cause it to melt and slide.
- Enhance Flavor: Adding a teaspoon of instant coffee to the batter intensifies the chocolate flavor naturally.
Variations and Customizations
- Chocolate Ganache: Pour a glossy ganache over the cake for a dramatic effect.
- Layered Cake: Add fruit jam, caramel, or peanut butter between layers for flavor variations.
- Chocolate-Chocolate Chip: Fold mini chocolate chips into the batter for pockets of melty chocolate.
- Gluten-Free Version: Substitute with a gluten-free all-purpose flour blend for a similarly moist texture.
- Moist Milk Cake Twist: Replace half of the hot water with milk for a richer batter.
Serving Suggestions
- Pair with vanilla ice cream or whipped cream for a decadent dessert experience.
- Serve with fresh berries or a drizzle of chocolate or caramel sauce.
- Perfect for birthday celebrations, holiday feasts, or casual gatherings — it’s always a hit.
Storage
- Room Temperature: Covered tightly, the cake will stay fresh for 2–3 days.
- Refrigeration: Store in the fridge for up to 5 days. Bring to room temperature before serving for best texture.
- Freezing: Wrap layers individually in plastic wrap and foil, freeze for up to 2 months. Thaw overnight in the fridge before frosting.
