- 2 large eggs: Bind the ingredients and add richness.
- ½ cup vegetable oil: Keeps the cake soft and moist without leaving a greasy texture.
- ½ cup milk: Adds moisture and helps achieve the perfect batter consistency.
- 1 tsp vanilla extract: Rounds out the flavor with warm, sweet notes.

How To Make Lemon Sourdough Discard Cake
Gather your pans and bowls—this recipe is all about simplicity and gentle mixing to ensure a tender crumb. From preheating the oven to drizzling on the final lemon glaze, each step is designed to be beginner-friendly while coaxing out the best bright, tangy flavors from your sourdough discard and fresh lemons.
1. Preheat your oven to 350°F (175°C). Grease an 8-inch round cake pan thoroughly and line the bottom with parchment paper to ensure an easy release.
2. In a medium bowl, whisk together 1 ½ cups all-purpose flour, 1 cup granulated sugar, 2 tsp baking powder, and ¼ tsp salt until everything is evenly distributed.
3. In a large bowl, vigorously whisk 2 large eggs, ½ cup vegetable oil, ½ cup milk, 1 tsp vanilla extract, 1 cup sourdough discard, the zest of 2 lemons, and 2 tbsp (half) fresh lemon juice until the mixture is silky and lump-free.
4. Pour the wet mixture into the dry ingredients and stir gently with a spatula just until combined; a few small lumps are okay—avoid overmixing to keep the cake light.
5. Transfer the batter to the prepared pan, using a spatula to smooth the top evenly.
6. Bake for 35-40 minutes or until a toothpick inserted into the center emerges clean or with just a few moist crumbs attached.
7. Let the cake cool in the pan for 10 minutes, then lift it out using the parchment paper and place it on a wire rack to cool completely.
8. Whisk 1 cup powdered sugar with the remaining 2 tbsp lemon juice until a smooth glaze forms, then drizzle it over the cooled cake, allowing it to set before slicing.

Frequently Asked Questions
Here are answers to the most common queries about this zesty cake:
- Q: How can I tell when I’ve mixed the batter enough without overmixing?
You should stir just until the dry ingredients disappear and the batter looks uniform, with no large streaks of flour. A few small lumps are fine. Overmixing develops gluten, which can lead to a dense crumb instead of a tender cake.
- Q: What if my sourdough discard is very tangy—will it affect the cake’s flavor balance?
A mild tang from fresh discard adds complexity and moisture. If your discard is older than 24 hours or tastes very sour, you can use ¾ cup discard and replace the remaining ¼ cup with milk to mellow the tang without compromising texture.
- Q: Can I substitute any of the dairy or oil in this recipe?
Yes. You can swap vegetable oil for melted coconut oil or light olive oil without altering texture. For milk, unsweetened almond, oat, or soy milk work well. Keep the same volume to maintain the batter’s consistency.
- Q: My toothpick comes out sticky after 40 minutes—what should I do?
Baking times can vary by oven. If a toothpick inserted in the center has crumbs clinging to it, return the cake to the oven for 3-5 more minutes. Check every couple of minutes to avoid overbaking. The cake is done when the toothpick is clean or has only a few moist crumbs attached.
- Q: Why is it important to let the cake cool completely before adding the glaze?
If you glaze a warm cake, the powdered sugar mixture will melt and run off, resulting in a thin, uneven coating. Cooling the cake fully on a wire rack ensures the glaze sets properly on the surface, creating a smooth, pretty finish.
- Q: How should I store leftovers to keep the cake moist?
Wrap the cooled cake tightly in plastic wrap or place it in an airtight container at room temperature. It stays moist and fresh for up to 2 days. For longer storage, refrigerate for up to 5 days, but allow the cake to come to room temperature before serving for best texture.
- Q: Can I make this recipe in advance or freeze slices?
Yes. Bake and cool the cake, then wrap it well in plastic wrap and aluminum foil. Freeze for up to 2 months. Thaw overnight in the refrigerator or on the counter before glazing. For serving later the same day, you can prepare the batter and keep it covered in the fridge for up to 4 hours before baking.
