For the Cake
- All-purpose flour: Provides the structure for a sturdy yet soft cake crumb.

Ingredients
Cake Batter
- 2 cups all-purpose flour
- 1 cup granulated sugar
- 3/4 cup unsweetened cocoa powder
- 2 tsp baking soda
- 1 tsp baking powder
- 1 tsp salt
- 2 large eggs at room temperature
- 1 cup buttermilk at room temperature
- 1/2 cup vegetable oil
- 2 tsp pure vanilla extract
- 1 cup hot water
Frosting
- 1 cup unsalted butter softened
- 4 cups powdered sugar
- 1/2 cup unsweetened cocoa powder
- 1/3 cup whole milk
- 2 tsp pure vanilla extract
- 1/4 tsp salt
Instructions
- Preheat your oven to 350°F (175°C). Grease and flour two 9-inch round cake pans, or line them with parchment paper.
- In the bowl of a stand mixer fitted with the paddle attachment, whisk together the all-purpose flour, granulated sugar, cocoa powder, baking soda, baking powder, and salt on low speed until fully combined.
- Add the eggs, buttermilk, vegetable oil, and vanilla extract to the dry ingredients. Mix on medium speed for 2 minutes, until the batter is smooth and well blended. Slowly pour in the hot water and mix on low speed until the batter is thin but uniform.
- Divide the batter evenly between the two prepared cake pans. Bake for 30 to 35 minutes, or until a toothpick inserted into the center of the cakes comes out clean.
- Let the cakes cool in their pans on a wire rack for 10 minutes. Then, run a knife around the edges and carefully invert the cakes onto the rack to cool completely, about 1 hour.
- Beat the softened butter in a clean stand mixer bowl on medium speed for 2 minutes until creamy. Gradually add the powdered sugar and cocoa powder, alternating with the milk, and beat on low speed until incorporated. Add the vanilla and salt, then increase speed to high and beat for 3 minutes until the frosting is light and fluffy.
- Place one cooled cake layer on a serving plate. Spread about 1 cup of frosting evenly over the top with an offset spatula. Top with the second cake layer. Frost the top and sides of the entire cake with the remaining frosting.
Notes
Simple Ways to Customize Your Cake
- Chocolate Ganache Drip: For an extra decadent touch, pour a smooth chocolate ganache over the frosted cake.
- Add Espresso Powder: Mix a teaspoon of instant espresso into the dry ingredients to deepen the chocolate flavor.
- Festive Sprinkles: Decorate the top with colorful sprinkles to match a holiday or birthday theme.
My Pro Tips for a Flawless Cake
- Proper Pan Prep: Grease, flour, and line your pans with parchment for effortless cake release every time.
- Room Temperature Ingredients: Using room temperature eggs and buttermilk helps create a smooth, homogenous batter that bakes evenly. This is a key step I also emphasize in my chicken pot pie for the flakiest crust.
- Don’t Overmix: Once you add the dry ingredients, mix just until combined to avoid a tough cake.
- Test for Doneness: The cake is done when a toothpick inserted in the center comes out with a few moist crumbs attached.
How to Keep Your Cake Fresh
- Store: Keep the frosted cake covered with a cake dome or in an airtight container at room temperature for up to 3 days. For longer storage, refrigerate for up to 5 days.
- Freeze: Wrap unfrosted cake layers tightly in plastic wrap and then aluminum foil. Freeze for up to 3 months. Thaw overnight in the refrigerator before frosting.
- Reheat: For a warm cake experience, microwave a single slice for 10-15 seconds. This works beautifully if you’re enjoying a slice with a side of creamy mac and cheese for a comforting meal and dessert combo.
- Make-Ahead Tip: You can bake the cake layers up to two days in advance. Wrap them well and store at room temperature until you are ready to frost and serve.
Frequently Asked Questions
Can I make this chocolate cake without buttermilk?
Yes, you can make a simple buttermilk substitute. For each cup of buttermilk, place one tablespoon of white vinegar or lemon juice in a measuring cup and add enough regular milk to make one cup. Stir and let it sit for 5 minutes until it curdles slightly before using.
Why did my cake sink in the middle?
A cake can sink if it is underbaked, if the oven door is opened too early, or if there is too much leavening agent. Be sure to test for doneness with a toothpick and avoid opening the oven door during the first 25 minutes of baking.
Can I make cupcakes with this recipe?
Absolutely. This batter works perfectly for cupcakes. Line a muffin tin with liners and fill each about two-thirds full. Bake at 350°F for 18-22 minutes, or until a toothpick comes out clean. This recipe will yield about 24 cupcakes.
How can I make a smoother frosting?
For the smoothest frosting, ensure your butter is properly softened and sift your powdered sugar and cocoa powder. Beat the butter for a full 2-3 minutes until it is very light and pale before gradually adding the other ingredients.
