Ingredients for Homemade Sourdough Chocolate Cake
Dry Ingredients

- 1 cup cocoa powder
- 1½ cups sugar
- 1 teaspoon baking soda
- 1 teaspoon baking powder
- ½ teaspoon salt
Wet Ingredients
- 1 cup sourdough discard or active starter
- 2 large eggs
- 1 cup milk
- ½ cup vegetable oil
- 1 teaspoon vanilla extract
- 1 cup hot coffee or hot water
Optional Chocolate Frosting
- 1 cup butter, softened
- 3 cups powdered sugar
- ½ cup cocoa powder
- 2–3 tablespoons milk
- 1 teaspoon vanilla extract
Step-by-Step Instructions
Step 1: Prepare the Oven
Preheat your oven to 350°F (175°C). Grease a 9-inch cake pan or line it with parchment paper.
Helpful tip: Properly greasing the pan helps the cake come out easily without sticking.
Step 2: Mix the Dry Ingredients
In a large bowl, combine:
- Flour
- Cocoa powder
- Sugar
- Baking soda
- Baking powder
- Salt
Mix everything well so the ingredients are evenly combined.
Step 3: Add the Wet Ingredients
Add the sourdough starter, eggs, milk, oil, and vanilla extract into the dry mixture.
Mix gently until smooth.
Do not overmix the batter. A few small lumps are completely fine.
Step 4: Add Hot Coffee
Slowly pour in the hot coffee or hot water while stirring carefully.
The batter will look thin, and that is perfectly normal. This step makes the Homemade Sourdough Chocolate Cake extra moist and rich.
Step 5: Bake the Cake
Pour the batter into the prepared cake pan.
Bake for 30–35 minutes or until a toothpick inserted in the center comes out clean.
Let the cake cool for at least 15 minutes before removing it from the pan.
Step 6: Make the Frosting
While the cake cools, beat the butter until creamy.
Add powdered sugar, cocoa powder, vanilla, and milk. Mix until smooth and fluffy.
Spread the frosting over the cooled cake.
Pro Tips & Variations
Use Room Temperature Ingredients
This helps everything mix together more smoothly.
Do Not Skip the Coffee

Add Chocolate Chips
Mix in ½ cup chocolate chips for extra richness.
Make It Healthier
You can replace half of the flour with whole wheat flour.
Avoid Overbaking
Overbaking can make the cake dry. Start checking the cake a few minutes early.

Cream cheese frosting or chocolate ganache also taste amazing with this cake.
