Ingredients
For the Chocolate Cake
1 ¾ cups all-purpose flour
1 ¾ cups granulated sugar
¾ cup unsweetened cocoa powder
1 ½ teaspoons baking powder
1 ½ teaspoons baking soda
1 teaspoon salt
2 large eggs
1 cup buttermilk
½ cup vegetable oil
2 teaspoons vanilla extract
1 cup hot coffee (or hot water)
Optional Chocolate Frosting
1 cup unsalted butter, softened
3 ½ cups powdered sugar
½ cup cocoa powder
¼ cup heavy cream
1 teaspoon vanilla extract
Step-by-Step Instructions
1. Prepare Your Pans
Preheat oven to 350°F (175°C).
Grease and flour two 9-inch round pans or one 9×13-inch pan.
Line bottoms with parchment paper for easy release.
2. Mix Dry Ingredients
In a large bowl, whisk together:
Flour
Sugar
Cocoa powder
Baking powder
Baking soda
Salt
Make sure everything is evenly combined to prevent lumps.
3. Add Wet Ingredients
Add eggs, buttermilk, oil, and vanilla.
Beat until smooth.
Slowly pour in hot coffee (this enhances chocolate flavor).
Mix until fully incorporated. Batter will be thin — that’s normal.
4. Bake
Pour batter evenly into prepared pans.
Bake for 30–35 minutes (round pans) or 35–40 minutes (9×13 pan).
Insert toothpick in center — it should come out clean or with a few moist crumbs.
5. Cool
Let cakes cool in pans for 10 minutes.
Transfer to wire rack to cool completely before frosting.
Chocolate Frosting (Optional)
Beat butter until creamy.
Add cocoa powder and mix well.
Gradually add powdered sugar.
Add cream and vanilla.
Beat until fluffy and spreadable.
Spread over cooled cake.
Why Buttermilk Makes a Difference
Buttermilk chocolate cake stands out because:
The acidity tenderizes gluten.
It creates a softer crumb.
It reacts with baking soda for extra lift.
It enhances chocolate richness.
If you don’t have buttermilk:
Mix 1 cup milk + 1 tablespoon lemon juice or vinegar.
Let sit for 5 minutes before using.
Pro Tips for the Best Chocolate Buttermilk Cake
Use high-quality cocoa powder.
Don’t overmix once flour is added.
