Ingredients
Instructions
1. Preheat your oven to 350 F (175 C). Grease and flour a 9×13 inch baking pan, or spray it well with non-stick baking spray.
2. In a medium bowl, whisk together the all-purpose flour, baking powder, baking soda, and salt. Set this bowl aside.
3. In a large mixing bowl, using an electric mixer, cream together the softened unsalted butter and granulated sugar until the mixture is light and fluffy, about 2-3 minutes.
4. Beat in the eggs one at a time, mixing well after each addition until fully incorporated. Stir in the vanilla extract and the sourdough discard.
5. Gradually add the dry ingredient mixture to the wet ingredients, alternating with the milk. Begin and end with the dry ingredients. Mix only until just combined; avoid overmixing.
6. Gently fold in the lemon zest.
7. Pour the batter evenly into your prepared baking pan. Bake for 30-35 minutes, or until a wooden skewer or toothpick inserted into the center of the cake comes out clean. The cake should be golden brown on top and spring back lightly when touched.
8. While the cake cools slightly in the pan (about 10-15 minutes), prepare the lemon glaze. In a small bowl, whisk together the powdered sugar and fresh lemon juice until smooth. Start with 3 tablespoons of lemon juice and add more a tiny bit at a time until you reach your desired consistency.
9. Once the cake has cooled slightly, drizzle the glaze evenly over the top. Let the glaze set before slicing and serving.

First, it’s an ingenious way to utilize sourdough discard, transforming what might otherwise be waste into a delicious dessert. For homesteaders or anyone who maintains a sourdough starter, this recipe offers a practical and tasty solution for that extra discard. Beyond its resourcefulness, the cake itself is incredibly moist and tender, thanks to the sourdough discard which adds a subtle depth of flavor without being overtly sour. The bright, tangy lemon glaze perfectly complements the cake, creating a refreshing taste that’s especially wonderful during warmer months.
This recipe is perfect for a casual family dessert, a potluck contribution, or a lovely treat to share with friends over coffee. It’s simple enough for beginner bakers but impressive enough for any occasion. The flavors are balanced and appealing to a wide range of palates, making it a reliable choice when you want to bake something everyone will enjoy.

Everything You Need To Make This Recipe Without Stress
Gathering your ingredients before you start baking makes the whole process smoother and more enjoyable. This recipe uses common pantry staples, ensuring you won’t need to hunt for obscure items. The star, of course, is your sourdough discard, which should be unfed and at room temperature for the best results.
INGREDIENTS:

- 1 ½ cups all-purpose flour
- 1 teaspoon baking powder
- ½ teaspoon baking soda
- ½ teaspoon salt
- ½ cup unsalted butter, softened
- 1 cup granulated sugar
- 2 large eggs
- 1 teaspoon vanilla extract
- 1 cup sourdough discard, unfed and at room temperature
- ½ cup whole milk
- Zest of 1 large lemon
- 1 ½ cups powdered sugar
- 3-4 tablespoons fresh lemon juice
You can easily make a few simple substitutions if needed. If you don’t have whole milk, 2% milk will work just fine, though it might result in a slightly less rich cake. For the lemon zest, if you don’t have a fresh lemon, you can use about 1 teaspoon of lemon extract in the batter, but fresh zest offers a brighter, more natural flavor. When it comes to butter, make sure it’s truly softened to room temperature for easier creaming; if it’s too cold, it won’t incorporate properly, and if it’s melted, it can change the cake’s texture. For the lemon glaze, fresh lemon juice is key for that vibrant tang, so avoid bottled juice if possible.

One of the best aspects of this sourdough lemon glaze cake is how quickly it comes together, making it a fantastic option for when you want a homemade treat without spending hours in the kitchen.
- Preparation Time: 15 minutes
- Baking Time: 30-35 minutes
- Cooling and Glazing Time: 20 minutes
- Total Time: Approximately 1 hour 5 minutes – 1 hour 10 minutes

How To Make It Step By Step With Visual Cues

Following these steps will lead you to a perfectly moist and flavorful sourdough lemon glaze cake. Pay attention to the cues for each stage to ensure the best results.
- Prepare Your Baking Pan and Oven: Preheat your oven to 350°F (175°C). Grease and flour a 9×13 inch baking pan, or spray it well with non-stick baking spray. This prevents the cake from sticking and ensures easy removal.
- Combine Dry Ingredients: In a medium bowl, whisk together the all-purpose flour, baking powder, baking soda, and salt. Make sure these are thoroughly combined to ensure even leavening throughout the cake. Set this bowl aside.
- Cream Butter and Sugar: In a large mixing bowl, using an electric mixer, cream together the softened unsalted butter and granulated sugar until the mixture is light and fluffy. This usually takes about 2-3 minutes. The mixture should be pale yellow and airy, indicating that air has been incorporated, which contributes to the cake’s tenderness.
- Add Wet Ingredients (Eggs, Vanilla, Sourdough Discard): Beat in the eggs one at a time, mixing well after each addition until fully incorporated. Stir in the vanilla extract and the sourdough discard. The mixture might look a little curdled at this stage, but don’t worry; it will come together as you add the dry ingredients.
- Alternate Dry and Wet Additions: Gradually add the dry ingredient mixture to the wet ingredients, alternating with the milk. Begin and end with the dry ingredients. For example, add about a third of the flour mixture, mix until just combined, then add half the milk, mix, then another third of the flour, mix, the remaining milk, mix, and finally the last third of the flour mixture. Mix only until just combined; overmixing can lead to a tough cake.
- Fold in Lemon Zest: Gently fold in the lemon zest. This adds a burst of fresh lemon flavor without overworking the batter.
- Bake the Cake: Pour the batter evenly into your prepared baking pan. Bake for 30-35 minutes, or until a wooden skewer or toothpick inserted into the center of the cake comes out clean. The cake should be golden brown on top and spring back lightly when touched.
- Prepare and Apply Glaze: While the cake cools slightly in the pan (about 10-15 minutes), prepare the lemon glaze. In a small bowl, whisk together the powdered sugar and fresh lemon juice until smooth. Start with 3 tablespoons of lemon juice and add more a tiny bit at a time until you reach your desired consistency – it should be thick enough to coat a spoon but pourable. Once the cake has cooled slightly, drizzle the glaze evenly over the top. Let the glaze set before slicing and serving.
Easy Variations And Serving Ideas That Fit Real Life
This sourdough lemon glaze cake is wonderfully versatile and can be adapted to suit different tastes and occasions. Here are some ideas to make it even more special:
For a berry burst, fold in ½ cup of fresh blueberries or raspberries into the batter just before baking. The tartness of the berries pairs beautifully with the lemon. If you’re serving it to kids, consider adding some colorful sprinkles to the glaze for a fun touch.
To make it a bit more decadent for a party or buffet, serve individual slices with a dollop of whipped cream and a few extra fresh berries. A sprig of fresh mint can also add an elegant touch. For a more intense lemon flavor, you can add an extra teaspoon of lemon zest to the glaze itself.
Consider a coconut-lemon twist by adding ½ cup of shredded unsweetened coconut to the cake batter. This adds a lovely texture and tropical hint. You could even sprinkle toasted coconut flakes over the glaze.
For a warm dessert, serve slices slightly warmed with a scoop of vanilla bean ice cream. The contrast between the warm cake and cold ice cream is delightful. This cake also makes a fantastic addition to a brunch spread, alongside fresh fruit and coffee.
Common Slip-Ups And How To Avoid Them
Even simple recipes can have common pitfalls. Knowing what to watch out for can help you achieve a perfect sourdough lemon glaze cake every time.
One frequent mistake is overmixing the batter. Once you add the flour, mix only until the ingredients are just combined. Overmixing develops the gluten in the flour too much, leading to a tough, dense cake instead of a light and tender one. Stop mixing as soon as you no longer see streaks of dry flour.
Another common issue is using cold ingredients. Ensure your butter and sourdough discard are at room temperature. Cold butter won’t cream properly with sugar, affecting the cake’s texture. Cold sourdough discard can also impact the batter’s consistency and how it incorporates. If your discard is straight from the fridge, let it sit on the counter for an hour or two before you start.
Incorrect oven temperature can also cause problems. An oven that’s too hot can burn the outside while leaving the inside raw, while an oven that’s too cool can result in a dry, crumbly cake. It’s a good idea to use an oven thermometer to verify your oven’s actual temperature.
