Ingredients
For the Chocolate Cake
- 1 cup sourdough discard
- 2 cups all-purpose flour
- 1 cup cocoa powder
- 1½ cups sugar
- 1 teaspoon baking soda
- 1 teaspoon baking powder
- ½ teaspoon salt
- 2 eggs
- 1 cup milk
- ½ cup vegetable oil
- 1 teaspoon vanilla extract
- 1 cup hot coffee or hot water
For the Chocolate Ganache
- 1 cup heavy cream
- 200g dark chocolate
- 1 tablespoon butter
Optional Toppings
- Chocolate curls
- Chocolate chips
- Fresh berries
- Crushed cookies
- Melted chocolate drizzle
Step-by-Step Instructions
Step 1: Prepare the Oven
Preheat your oven to 350°F (175°C). Grease two round cake pans with butter or oil and line them with parchment paper. This helps the cakes release easily after baking.
Step 2: Mix the Dry Ingredients
In a large bowl, whisk together:
- Flour
- Cocoa powder
- Sugar
- Baking soda
- Baking powder
- Salt
Mixing the dry ingredients first ensures the cocoa and leavening agents are evenly distributed.
Step 3: Add the Wet Ingredients
In another bowl, combine:
- Sourdough discard
- Eggs
- Milk
- Oil
- Vanilla extract
Whisk until smooth and creamy. Slowly pour the wet mixture into the dry ingredients.
Step 4: Add Hot Coffee
Gradually add the hot coffee while stirring gently. The batter will become thin, but that’s completely normal. Hot coffee enhances the chocolate flavor and makes the cake extra rich.
If you don’t like coffee, you can use hot water instead.
Step 5: Bake the Cake
Divide the batter evenly between the prepared pans. Bake for 30–35 minutes or until a toothpick inserted into the center comes out clean.
Once baked, let the cakes cool in the pans for 10 minutes before transferring them to a wire rack.
Making the Chocolate Ganache
Ganache is what makes this cake look bakery-style and taste luxurious.
Step 1: Heat the Cream
In a small saucepan, heat the cream until it starts to simmer. Do not boil it.
Step 2: Melt the Chocolate
Pour the hot cream over chopped dark chocolate in a bowl. Let it sit for 2 minutes, then stir until smooth and glossy.
Add butter for extra shine.
Assembling the Cake
Place one cake layer on a serving plate. Spread a generous amount of ganache over the top. Add the second cake layer and pour the remaining ganache over the entire cake.
Let the chocolate drip naturally down the sides for that beautiful homemade bakery look.
Decorate with chocolate curls, chips, or berries if desired.
Tips for the Perfect Sourdough Cake
Use Room Temperature Ingredients
Room temperature eggs and milk mix better into the batter and create a softer texture.
Don’t Overmix
Overmixing can make the cake dense instead of fluffy. Stir only until everything is combined.
Use Good Quality Cocoa
High-quality cocoa powder gives a richer and deeper chocolate flavor.
Cool Before Frosting
If the cake is warm, the ganache may melt too much and slide off.
Why Sourdough Works in Cake
Sourdough discard adds moisture and tenderness to baked goods. It also creates a more complex flavor compared to regular cakes. The natural fermentation gives the cake a slight richness that makes every bite taste homemade and special.
Many bakers love using sourdough discard because it reduces waste while adding amazing texture to recipes.
