Rich Sourdough Chocolate Cake with Raspberries
Tina BevkThis Sourdough Chocolate Cake with Raspberries is one of my favorite ways to use sourdough discard—it’s rich, moist, and loaded with flavor. I’ve made this cake countless times, tweaking it along the way, and it never fails to impress. The tart raspberries balance the sweet, chocolatey base perfectly, and the addition of sourdough gives it an incredible depth of flavor.
I’ve also tried this recipe with chopped cherries instead of raspberries, and let me tell you, it was just as delicious!

Rich Sourdough Chocolate Cake with Raspberries
Ingredients
For the Cake
- 1 cup sourdough starter discard
- 1 + 1/2 cup all purpose flour
- 1/2 cup cocoa powder Dutch process
- 1 + 1/2 tsp baking powder
- 1/2 tsp baking soda
- 1/4 tsp salt
- 1 cup brown sugar
- 1/2 cup greek yogurt
- 1/2 cup butter unsalted, softened
- 2 eggs
- 1 tsp vanilla extract
- 1 cup raspberries fresh or frozen
- 1/2 cup chocolate chips your favorite ones
Optional: For the Frosting
- 1/2 can condensed milk sweetened
- 1 tbsp cocoa powder Dutch process
- 2 tbsp butter unsalted, softened
- 1 tsp vanilla extract
- a pinch of salt
- a pinch of ground espresso beans
Instructions
- Preheat the oven to 350°F (175°C) and grease a 9-inch pan. In a bowl, whisk together the flour, cocoa powder, baking powder, baking soda, and salt. Set aside.
- In a mixing bowl, beat the softened butter and brown sugar on low speed until light and fluffy. Add the eggs one at a time, mixing well after each addition. Then, mix in the vanilla and Greek yogurt.
- Mix in the sourdough discard until the batter is uniform.
- Alternate adding the dry ingredients and the milk to the batter in small amounts, mixing gently after each addition until smooth.
- Gently fold in the raspberries and chocolate chips. If using fresh fruit, toss it with a bit of flour first to prevent sinking.
- Pour the batter into the prepared pan and smooth the top. Bake for 55-60 minutes, or until a toothpick inserted in the center comes out clean. Let cool in the pan for 10 minutes, then transfer to a wire rack to cool completely.
- Optional – Make the Frosting: Mix the sweetened condensed milk and cocoa powder until smooth. Add the butter, vanilla, salt, and espresso powder (if using). Stir until uniform. Spread over the cooled cake.
Notes
- if you’re using fresh fruit, toss it with a tablespoon of flour before folding it into the batter—this keeps the fruit evenly distributed and prevents it from sinking.
- use Dutch process cocoa for the richest chocolate flavor, and don’t skip the Greek yogurt—it keeps the cake moist and balances the sweetness perfectly.
