1. Prepare the Cake Pans
- Preheat the Oven: Preheat your oven to 350°F (175°C).
- Prepare the Pans: Grease and flour two 9-inch round cake pans. You can also line the bottoms with parchment paper for easier removal.
2. Make the Cake Batter
- Combine Dry Ingredients: In a large mixing bowl, sift together the flour, baking powder, baking soda, cocoa powder, sugar, and salt.
- Mix Wet Ingredients: In a separate bowl, whisk together the eggs, milk, oil, and vanilla extract.
- Combine Wet and Dry Ingredients: Gradually add the wet ingredients to the dry ingredients, mixing until well combined.
- Add Boiling Water: Slowly add the boiling water to the batter, mixing on low speed until combined. The batter will be very thin, but this is normal.
- Add Buttermilk: Gently stir in the buttermilk until the batter is smooth.
3. Bake the Cake
- Pour Batter into Pans: Divide the batter evenly between the prepared cake pans.
- Bake: Bake in the preheated oven for 30-35 minutes, or until a toothpick inserted into the center of the cakes comes out clean.
- Cool: Allow the cakes to cool in the pans for 10 minutes, then turn them out onto a wire rack to cool completely.
4. Make the Chocolate Frosting
- Cream Butter and Cocoa: In a large mixing bowl, cream together the softened butter and cocoa powder until well combined and smooth.
- Add Sugar and Milk: Gradually add the powdered sugar, one cup at a time, alternating with the milk. Beat on medium speed until smooth and creamy. Add more milk if the frosting is too thick.
- Add Vanilla and Salt: Stir in the vanilla extract and salt, mixing until the frosting is well combined.
5. Assemble the Cake
- Level the Cakes: If needed, level the tops of the cakes with a sharp knife or a cake leveler to ensure they are flat.
- Frost the First Layer: Place one cake layer on a serving plate or cake stand. Spread a thick, even layer of frosting over the top.
- Add the Second Layer: Place the second cake layer on top of the first, and press down gently to secure.
- Frost the Top and Sides: Use the remaining frosting to cover the top and sides of the cake, smoothing it out with a spatula or cake scraper.
6. Serve and Enjoy
- Decorate: If desired, decorate the cake with chocolate shavings, sprinkles, or fresh berries.
- Serve: Slice the cake and serve. Enjoy the rich, chocolatey goodness!
Tips for Success
- Room Temperature Ingredients: Ensure that your eggs, milk, and buttermilk are at room temperature for a smoother batter and better rise.
- Sift Dry Ingredients: Sifting the dry ingredients helps to remove lumps and ensures an even distribution of the leavening agents.
- Buttermilk Substitute: If you don’t have buttermilk, you can make a substitute by adding 1 tablespoon of vinegar or lemon juice to a cup of milk and letting it sit for 5 minutes.
Variations
- Mocha Cake: Add 1 tablespoon of instant coffee granules to the boiling water for a subtle coffee flavor.
- Chocolate Orange Cake: Add 1 teaspoon of orange zest to the batter and use orange extract in the frosting.
- Nutty Chocolate Cake: Stir in 1 cup of chopped nuts (such as walnuts or pecans) into the batter for added texture and flavor.
