Prep Time: 30 minutes | Cook Time: 30 minutes | Total Time: 1 hour (plus cooling) | Servings: 12-16 slices
Ingredients
For the Chocolate Cake Layers:
- 2½ cups all-purpose flour
- 2 cups granulated sugar
- ¾ cup unsweetened cocoa powder
- 2 teaspoons baking powder
- 1½ teaspoons baking soda
- 1 teaspoon salt
- 3 large eggs (room temperature)
- 1½ cups buttermilk (or 1 tablespoon vinegar + milk to make 1½ cups)
- ¾ cup vegetable oil (or melted coconut oil)
- 2 teaspoons vanilla extract
- 1 cup hot coffee or water
For the Chocolate Fudge Frosting:
- 1 cup butter (softened)
- 1 cup unsweetened cocoa powder (sifted)
- 4 cups powdered sugar
- ⅓ to ½ cup heavy cream
- 2 teaspoons vanilla extract
- ½ teaspoon salt
- 1 teaspoon espresso powder (optional)
For Decoration:
- Extra frosting for piping (about 1 cup)
- Chocolate shavings or sprinkles (optional)
Step-by-Step Instructions
1. Prep Your Pans
Preheat your oven to 350°F. Grease three 8-inch or 9-inch round cake pans and line the bottoms with parchment paper circles. This ensures easy removal.
2. Mix the Cake Batter
In a large bowl, whisk together flour, sugar, cocoa powder, baking powder, baking soda, and salt. In another bowl, whisk eggs, buttermilk, oil, and vanilla until smooth. Pour wet ingredients into dry ingredients and mix on medium speed until just combined. Slowly add hot coffee while mixing on low until batter is smooth (it will be thin).
3. Bake the Layers
Divide batter evenly among pans. Bake for 25-30 minutes (for three pans) or 30-35 minutes (for two pans) until a toothpick comes out clean. Cool in pans for 10 minutes, then transfer to wire racks to cool completely.
4. Make the Fudge Frosting
Beat softened butter until fluffy (2 minutes). Add cocoa powder and mix on low. Gradually add powdered sugar, then vanilla, salt, and espresso powder. Slowly pour in heavy cream until frosting is smooth and spreadable. Beat on high for 2-3 minutes until light.
5. Assemble the Cake
Place the first cake layer on a serving plate. Spread 1 cup frosting evenly. Repeat with remaining layers. Cover the top and sides with a crumb coat, refrigerate for 15 minutes, then frost fully.
6. Pipe and Decorate
Pipe reserved frosting into rosettes or swirls. Top with chocolate shavings or sprinkles.
Pro Tips for Perfect Results
- Use room temperature ingredients for smoother batter and frosting.
- Sift cocoa powder to avoid lumps in the frosting.
- Don’t overmix the batter—stop as soon as ingredients combine.
- Cool cakes completely before frosting to prevent melting.
- For clean slices, dip a knife in hot water before cutting.
Variations and Substitutions
- Healthier swaps: Substitute half the flour with whole wheat, or use coconut sugar instead of granulated sugar.
- Dairy-free: Use plant-based butter and coconut milk in place of buttermilk.
- Gluten-free: Replace all-purpose flour with a 1:1 gluten-free blend.
- Flavor twists: Add orange zest to the batter or a pinch of cinnamon to the frosting.
Storage and Reheating Tips
Store covered at room temperature for up to 2 days or refrigerate for up to 5 days. Bring to room temperature before serving. Freeze unfrosted layers wrapped in plastic for up to 3 months. Thaw overnight before frosting.
FAQ
Can I make this cake ahead of time?
Yes! Bake the layers a day in advance and store them wrapped at room temperature. Frost the day of serving.
What if I don’t have buttermilk?
Mix 1 tablespoon vinegar or lemon juice with enough milk to make 1½ cups. Let sit for 5 minutes before using.
Can I use butter instead of oil in the cake?
Oil keeps the cake moist longer, but melted butter can be substituted in equal amounts.
Why add coffee to the batter?
Hot coffee enhances the chocolate flavor without making the cake taste like coffee.
How do I prevent domed cake layers?
Bake at 325°F for slightly longer, or trim the domes with a serrated knife after cooling.
