- 1 teaspoon vanilla extract
- 1 1/2 cups all-purpose flour
- 1 teaspoon baking powder

How To Make Sourdough Lemon Cake Step by Step
- Preheat your oven to 350°F (175°C) and grease a 9-inch round cake pan to prevent sticking.
- In a large mixing bowl, cream together the softened butter and granulated sugar until the mixture is light and fluffy. This step ensures the cake will have a tender crumb.
- Add the eggs one at a time, mixing thoroughly after each addition for a smooth batter.
- Stir in the sourdough starter, fresh lemon juice, lemon zest, and vanilla extract until fully combined. These ingredients give the cake its signature tang and aroma.
- In a separate bowl, whisk together the all-purpose flour, baking powder, baking soda, and salt. This dry mix provides structure to the cake.
- Gradually mix the dry ingredients into the wet mixture, alternating with the buttermilk. Be careful not to overmix to keep the cake light and airy.
- Pour the batter into the prepared pan and use a spatula to smooth the surface for even baking.
- Bake for 30-35 minutes, or until a toothpick inserted in the center comes out clean. Avoid overbaking to keep the cake moist.
- Let the cake cool in the pan for 10 minutes, then transfer it to a wire rack to cool completely before serving.

Frequently Asked Questions
- Can I use sourdough discard for this recipe?
- Yes, you can use sourdough discard as long as it’s fresh and active. It won’t impact the cake’s rise or flavor as long as your discard isn’t overly sour.
- What can I use instead of buttermilk?
- If you don’t have buttermilk, you can make a substitute by mixing 1/2 cup of milk with 1/2 tablespoon of lemon juice or white vinegar. Let it sit for 5 minutes before using.
- How do I know when the cake is done baking?
- The cake is ready when a toothpick or skewer inserted in the center comes out clean or with a few crumbs. Avoid opening the oven door frequently while baking to ensure an even rise.

Expert Tips for Sourdough Lemon Cake
- Bring all ingredients to room temperature before starting. This helps them blend more easily and results in a smoother batter.
- Use fine-grated lemon zest to avoid any bitter notes in the cake. A microplane grater works best for this.
- Don’t overmix the batter once the dry ingredients are added. Overmixing can lead to a dense texture.
- Cool the cake completely before slicing or frosting. This step ensures cleaner slices and prevents the frosting from melting.
