Ingredients
There are only a few key ingredients you'll need to bring this loaf cake together.
- Sourdough discard: The sourdough discard should be unfed and at room temperature for this recipe. This recipe is designed for a sourdough starter with a 1:1 ratio (when you feed your starter, it's with 1 part flour and 1 part water). If your starter uses a different ratio, you may need to adjust some of the ingredients in this recipe.
- Lemon juice and zest: Fresh-squeezed lemon juice and fresh lemon zest will give you the best flavor! You'll need one lemon for this recipe.
- Raspberries: Fresh raspberries will be best, but frozen would work as well!

Substitutions & Variations
This is a very adaptable recipe; below are a few easy substitutions and variations you can try.
- Use active sourdough starter - If you'd like to use active sourdough starter instead of sourdough discard, you can, although it's not necessary for leavening purposes. I'd recommend sticking with discard, but if you're determined to use active starter, you can replace the discard in a 1:1 substitution.
- Use different berries - This recipe is great with raspberries, but would also be delicious with blackberries or blueberries! You might also like this Sourdough Discard Strawberry Cake.
- Use different yogurt - There is only 1 Tablespoon of yogurt in this recipe. I use a plain or vanilla-flavored non-dairy yogurt, but this will work with any kind of non-dairy or regular dairy yogurt (Greek yogurt included!).

Sourdough Lemon Raspberry Loaf Cake
Ingredients
- ¾ cup all-purpose flour
- 1 teaspoon baking powder
- ¼ teaspoon kosher salt
- 1 cup granulated sugar
- 4 Tablespoons unsalted butter softened
- 200 grams (about ¾cup) sourdough discard unfed, at room temperature
- 2 eggs room temperature
- 2 Tablespoons lemon zest
- 1 Tablespoon lemon juice
- 1 Tablespoon yogurt non-dairy or regular dairy
- 1 teaspoon vanilla extract
- 1 cup raspberries fresh or frozen
Lemon Glaze
- 1 cup powdered sugar
- 1 ½ Tablespoons lemon juice
- 1 teaspoon vanilla extract
Instructions
- Preheat the oven to 350°F. Grease a 9x5 inch loaf pan and line with parchment paper. Set aside.
- In a medium bowl, whisk together the flour, baking powder, and salt.
- In a large bowl, add the sugar and softened butter. Using a hand-held mixer, cream the butter and sugar until light and fluffy, about 2 minutes. Add the sourdough discard, eggs, lemon zest, lemon juice, yogurt, and vanilla extract. Mix until smooth and combined.
- Add the dry ingredients to the wet ingredients and mix until just combined. Using a spatula or wooden spoon, fold in the raspberries.
- Pour the batter into the prepared pan and bake for 60-70 minutes or until the top is golden and a toothpick inserted into the center of the loaf comes out clean. Remove from the oven and let cool for 10 minutes in the pan. Then remove the loaf from the pan (you can pick up the loaf from the edges of the parchment paper) and transfer to a wire rack to cool fully.
- Once the loaf has cooled, combine the powdered sugar, lemon juice and vanilla extract in a small bowl and whisk to combine. This will be a thick glaze. Pour over the cooled loaf, slice and enjoy!
