Method
Step 1: Prep and Preheat
- Preheat your oven to 350°F (175°C). Lightly grease two 9-inch round cake pans and dust them with flour. For easier removal, you can line the bottoms with parchment paper instead. This is the secret to cakes that pop right out!
Step 2: Mix the Dry Stuff
- In a large bowl, whisk together the flour, sugar, baking soda, salt, and cocoa powder. This ensures everything is evenly distributed for a perfect rise.2 ½ cups all-purpose flour, 1 ½ cups granulated sugar, 1 teaspoon baking soda, 1 teaspoon fine salt, 1 tablespoon unsweetened cocoa powder
Step 3: Combine the Wet Stuff
- In a separate medium bowl, whisk together the oil, buttermilk, eggs, black gel food coloring, vanilla extract, and vinegar until the mixture is smooth and uniformly black.1 ½ cups vegetable oil, 1 cup buttermilk, 2 large eggs, 2 tablespoons black gel food coloring, 1 teaspoon vanilla extract, 1 teaspoon white vinegar
Step 4: Bring It All Together
- Pour the wet ingredients into the dry ingredients. Gently whisk until just combined. A few small lumps are okay! Over-mixing is the enemy of a tender cake.
Step 5: Bake to Perfection
- Split the batter evenly between the pans. Bake for 30 to 35 minutes. They're done when a toothpick poked in the middle comes out clean.
Step 6: Cool and Frost
- Let the cakes sit in their pans for 10 minutes, then move them to a wire rack to finish cooling. This is crucial! If you frost a warm cake, the frosting will melt. Once completely cool, frost with the cream cheese frosting.
- Beat the softened cream cheese and butter together until smooth. Gradually add the sifted powdered sugar, vanilla, and salt, beating until it's light and fluffy.8 oz one block full-fat cream cheese, softened, ½ cup 1 stick unsalted butter, softened, 4 cups powdered sugar, 1 teaspoon vanilla extract, A pinch of salt
Notes
- Room Temperature is Key: Using room temperature eggs and buttermilk helps the ingredients emulsify and create a smooth, uniform batter.
- Don't Over-mix: Once you combine the wet and dry ingredients, mix until you no longer see streaks of flour. Over-mixing develops gluten and leads to a tough cake.
- Testing for Doneness: The toothpick test is your best friend. If it comes out with a few moist crumbs, that's perfect. If it comes out wet, it needs more time.
- Frosting Tip: For perfectly smooth frosting, ensure your cream cheese and butter are truly softened. This prevents lumps.
- Make it a Sheet Cake: You can also bake this in a 9x13 inch pan. Adjust the baking time—it may need 5-10 minutes longer.
