Ingredients
Instructions
1. Preheat your oven to 350 F (175 C). Grease and flour a 9×5-inch loaf pan, or line it with parchment paper, leaving an overhang on the long sides to easily lift the loaf out later.
2. In a medium bowl, whisk together the all-purpose flour, baking powder, baking soda, and salt. Set this aside.
3. In a large mixing bowl, using an electric mixer, cream together the softened butter and granulated sugar until the mixture is light and fluffy, about 2-3 minutes. Scrape down the sides of the bowl as needed.
4. Beat in the eggs one at a time, mixing well after each addition. Stir in the sourdough discard, fresh lemon juice, lemon zest, and vanilla extract until just combined. The mixture might look a little curdled, but don’t worry, it will come together.
5. Gradually add the dry ingredient mixture to the wet ingredients, mixing on low speed until just combined. Be careful not to overmix; overmixing can lead to a tough cake. A few streaks of flour are okay.
6. Pour the batter evenly into your prepared loaf pan. Bake for 45-55 minutes, or until a wooden skewer or toothpick inserted into the center of the loaf comes out clean. The top should be golden brown and spring back lightly when touched.
7. Let the loaf cool in the pan for about 10-15 minutes before carefully lifting it out onto a wire rack to cool completely. While the cake cools, prepare the glaze by whisking together the powdered sugar and lemon juice until smooth. Once the loaf is completely cool, drizzle the glaze evenly over the top.

Everything You Need To Make This Recipe Without Stress
Gathering your ingredients before you start baking is key to a smooth process. This recipe uses common pantry staples alongside your sourdough discard, ensuring you won’t need to make a special trip to the store for obscure items. The simplicity of the ingredient list contributes to the overall ease of making this delicious lemon loaf.
INGREDIENTS:

- 1 cup all-purpose flour
- 1 teaspoon baking powder
- 1/2 teaspoon baking soda
- 1/4 teaspoon salt
- 1/2 cup (1 stick) unsalted butter, softened
- 1 cup granulated sugar
- 2 large eggs
- 1 cup sourdough discard (unfed, at room temperature)
- 1/4 cup fresh lemon juice
- 1 tablespoon lemon zest
- 1 teaspoon vanilla extract
- For the Glaze:
- 1 cup powdered sugar
- 2-3 tablespoons fresh lemon juice
When selecting your ingredients, using fresh lemon juice and zest will make a noticeable difference in the brightness and intensity of the lemon flavor. For the butter, make sure it’s properly softened to room temperature so it creams easily with the sugar, creating a light and airy base for your cake. If you don’t have unsalted butter, salted butter can be used, but you might want to slightly reduce the added salt in the recipe. As for the sourdough discard, it should be unfed and at room temperature for the best results.
Time Needed From Start To Finish
This sourdough lemon loaf cake is a relatively quick bake, making it ideal for busy schedules or when you need a delicious treat without a lot of fuss.
- Preparation Time: 15-20 minutes
- Baking Time: 45-55 minutes
- Cooling and Glazing Time: 30 minutes
- Total Time: Approximately 1 hour 30 minutes to 1 hour 45 minutes
The hands-on time for mixing the batter is minimal, allowing you to get the loaf into the oven efficiently. The baking time ensures the cake is cooked through and golden brown, while the cooling period is essential for the glaze to set properly and for the cake to be sliceable.
How To Make It Step By Step With Visual Cues

Making this sourdough lemon loaf cake is a straightforward process. Follow these steps carefully for a perfectly moist and flavorful result.
- Prepare Your Baking Pan and Oven: Preheat your oven to 350°F (175°C). Grease and flour a 9×5-inch loaf pan, or line it with parchment paper, leaving an overhang on the long sides to easily lift the loaf out later.
- Combine Dry Ingredients: In a medium bowl, whisk together the all-purpose flour, baking powder, baking soda, and salt. Set this aside.
- Cream Butter and Sugar: In a large mixing bowl, using an electric mixer, cream together the softened butter and granulated sugar until the mixture is light and fluffy, about 2-3 minutes. Scrape down the sides of the bowl as needed.
- Add Eggs and Flavorings: Beat in the eggs one at a time, mixing well after each addition. Stir in the sourdough discard, fresh lemon juice, lemon zest, and vanilla extract until just combined. The mixture might look a little curdled, but don’t worry, it will come together.
- Incorporate Dry into Wet Ingredients: Gradually add the dry ingredient mixture to the wet ingredients, mixing on low speed until just combined. Be careful not to overmix; overmixing can lead to a tough cake. A few streaks of flour are okay.
- Bake the Loaf: Pour the batter evenly into your prepared loaf pan. Bake for 45-55 minutes, or until a wooden skewer or toothpick inserted into the center of the loaf comes out clean. The top should be golden brown and spring back lightly when touched.
- Cool and Glaze: Let the loaf cool in the pan for about 10-15 minutes before carefully lifting it out onto a wire rack to cool completely. While the cake cools, prepare the glaze by whisking together the powdered sugar and lemon juice until smooth. Once the loaf is completely cool, drizzle the glaze evenly over the top.
Easy Variations And Serving Ideas That Fit Real Life
This sourdough lemon loaf cake is wonderful as is, but there are many ways to adapt it to your taste or occasion. For a more intense lemon flavor, you can add an extra teaspoon of lemon zest to the batter. If you enjoy a bit of texture, consider folding in 1/2 cup of poppy seeds with the dry ingredients for a classic lemon poppy seed loaf. For a touch of sweetness and fruitiness, a handful of fresh or frozen (not thawed) blueberries or raspberries can be gently folded into the batter just before baking.
When it comes to serving, this loaf cake is incredibly versatile. It’s perfect for a simple breakfast with a cup of coffee or tea. For an afternoon treat, serve slices alongside a fresh fruit salad. If you’re hosting a brunch, arrange slices on a platter with extra lemon wedges for garnish. For a more decadent dessert, a slice can be lightly warmed and served with a dollop of whipped cream or a scoop of vanilla ice cream. It’s also an excellent choice for potlucks or bake sales, as it travels well and is a crowd-pleaser.
Common Slip-Ups And How To Avoid Them
Even simple recipes can have common pitfalls. Being aware of these can help ensure your sourdough lemon loaf cake turns out perfectly every time.
- Overmixing the Batter: This is one of the most frequent mistakes in baking. Overmixing develops the gluten in the flour too much, leading to a tough, dense cake rather than a tender one. Mix the dry and wet ingredients only until just combined, with a few streaks of flour still visible.
- Incorrect Butter Temperature: If your butter is too cold, it won’t cream properly with the sugar, resulting in a less airy texture. If it’s too warm (melted), the emulsion can break, and the cake might be greasy. Ensure your butter is softened to room temperature, where it yields to gentle pressure but isn’t oily.
- Opening the Oven Door Too Early: Resist the urge to check on your loaf too soon. Opening the oven door can cause a sudden drop in temperature, leading to the cake sinking in the middle. Wait until at least 3/4 of the baking time has passed before checking for doneness.
- Not Cooling Completely Before Glazing: If you glaze the loaf while it’s still warm, the glaze will melt and run off, rather than setting into a nice, opaque layer. Patience is key here; let the loaf cool completely on a wire rack before drizzling the glaze.
- Using Old Sourdough Discard: While this recipe uses discard, extremely old or neglected discard might have an off-flavor. For the best results, use discard that is no more than a week old and has been stored in the refrigerator.
How To Store It And Make It Ahead Without Ruining Texture
Proper storage is essential to keep your sourdough lemon loaf cake fresh and delicious. Once the glaze has set, you can store the loaf at room temperature in an airtight container for up to 3-4 days. This helps to maintain its moisture and prevents it from drying out. If your kitchen is particularly warm or humid, or if you want to extend its shelf life, you can store it in the refrigerator for up to a week. Just be aware that refrigeration can sometimes slightly alter the texture, making it a bit firmer.
For making ahead, this loaf cake freezes beautifully. Once completely cooled and glazed, wrap the entire loaf
