Simple Glazed Sourdough Lemon Cake
Somewhere between a dessert and a quick bread, this sourdough lemon cake mixes up quickly and gives you a nice moist loaf. But the really good part is the lemony sugar glaze that you pour on top while it’s still warm. So good. Often imitated, never duplicated, it’s one of my original sourdough discard recipes and still one of my very favorites.

Instructions
Make the Cake
- Prep. Preheat oven to 350 degrees with the rack in the center. Prepare a loaf pan or 9 x 9 square cake pan with cooking spray.
- Wet ingredients. Combine the vegetable oil, eggs, and sugar in a large mixing bowl with an electric mixer until well combined.
- Dry ingredients and milk. Mix the flour, baking powder, and salt in a separate bowl and add to the sugar mixture 1/3 at a time, alternating with the milk and the sourdough starter. Mix on low until just combined. Stir in the lemon juice and lemon zest by hand. Pour the batter into the prepared pan.
- Bake and cool. Bake for 50-60 minutes (for the loaf pan) or 40-50 minutes (for the square pan) until golden brown and a toothpick inserted into the center comes out clean. Place on a wire rack. Allow to cool for about 15 minutes in the pan.
Make The Glaze
- In a small bowl, combine the powdered sugar, lemon zest, and lemon juice for the glaze. Pour over the still-warm cake.
- After the glaze has soaked in and hardened, remove cake from pan and allow to finish cooling on wire rack. Slice and serve once cool.

Notes
Nutrition
The beauty of this recipe is that it’s simple enough to make all the time. Afternoon tea party, spring breakfast time, after school snack, whenever.
There’s no need to wait for anything to ferment or activate or rise; your discard can go straight from the fridge to your mixing bowl.
Tips for Success
Let the cake cool for exactly 15 minutes before glazing so the glaze to partially sinks in but still creates a nice finish.
Don’t skimp on the lemon zest – it’s where most of the flavor comes from.
A few readers have noted that their lemon cake has collapsed after baking. Since receiving that feedback, I’ve added some baking soda to the recipe to help leaven it further.
The baking soda is optional and will produce a lighter cake. I never use the baking soda. I prefer it with only baking powder because it has a denser, more pound cake-like texture.
The two most common causes of this are an underdone cake or inactive baking powder/ baking soda. Make sure your cake is fully baked by using a cake tester or a toothpick and remember that baking powder and baking soda should be replaced every 6 months.
The cake will look quite brown before it’s fully baked trust your cake tester more than the color. If it’s underbaked it will sink when you pull it out.

Sourdough discard: Can be used straight from the fridge – any level of activity is fine
Fresh lemons: Essential for both juice and zest – bottled juice won’t give you the same bright flavor
Baking powder: Must be fresh (within 6 months) for proper rise
Equipment: While an electric mixer makes things easier, you can make this by hand. A loaf pan or 9×9 square pan both work beautifully

- Add 1/2 cup of poppy seeds for a classic lemon poppyseed loaf.
- Try melted butter instead of oil for a richer flavor.
Common Questions
Usually this means it’s slightly underbaked or your leavening agents aren’t fresh. Try adding a teaspoon of baking soda along with the powder for extra insurance.
A toothpick inserted in the center should come out clean, and the cake should spring back when lightly pressed.
Like all the best recipes, this cake is quick for busy weekdays but good enough for company. Keep this one in your back pocket, and be sure to let me know how you like it.

I’ve made this twice. I added only 1/4 tsp baking soda the second time using the doubled recipe.. Very very good.
Do you recommend using all purpose? Or can you use bread flour?
bread flour is fine, i’ve used it in a pinch!
So pleased with this easy recipe! Turned out perfect and so yum! I used more fresh lemon juice also because I’m a lemon lover. I also probably used 3/4 cup active starter. Yum!
This recipe is fantastic! I used rhe butter instead of oil, but I just creamed it with the sugar and didn’t bother melting it. I also used 4tbsps of lemon juice because I’m a lemon freak. I’ve added blueberries, raspberries, and my niece just made it with huckleberries — all were delicious! Thank you!
Hi,
Is it possible to add a slider with Metric measurements to your recipes?
hi Grace! I’m working on this now! It will take me a week or so 🙂
Loved this cake. I used gluten free better batter for the flour and added some psyllium husk. Family had no idea it was gluten free!!! Thank you
Absolutely delicious cake! I made this for my sweet daughter in laws birthday and she loved it. I added fresh violets on top.
2 questions:
1. If I make + freeze, when I take it out to defrost and add glaze, should I warm it up in the oven for a few minutes so the glaze can soak in an harden?
2. If I use 1/2 oil + 1/2 butter, do I cream the butter + sugar for a few minutes before adding the other ingredients?
Hi Maria! 🙂 Yes I Would warm it up slightly, wrapepd inf oil so i t doesn’t dry out. I’d recommend melted butter instead! I’m so glad you liked it and the violets sound beautiful!
Delicious!!!!
Does the milk get mixed in with the rest of the wet ingredients?
My family cannot get enough of this lemon cake. I follow the recipe every time, and it turns out beautiful every time I make it! It is so easy to make too, which is another plus! Great way to use your discard!
Delightful lightly flavored cake that definitely needs the glaze on top for flavor. I probably would have preferred to use a cake pan instead of loaf pan. I’ll try that next time and have fresh fruit on the side.
Excellent and easy!
Could I add blueberries?
hey amy, yes!! I also have this recipe which you might like: https://heartscontentfarmhouse.com/sourdough-blueberry-quick-bread/
SO good! One pan was not enough!
Thank you for this recipe! I made it exactly as described but accidentally put a cup of milk so naturally I had to triple the recipe. I’m glad I did make that mistake because it is now a family favorite dessert!
Bread came out Beautiful and cooked for 50 min and added 10 more minutes and 10 more minutes! Cooked in a glass loaf pan.
wonderful, debora! thank you for letting me know!
This loaf was amazing!!! I followed the instructions and it turned out perfect. Thank you, I now have something other than crackers to make with my discard😊
Followed the directions to a T and it was mega runny and spilled out of the loaf pans onto the bottom of the oven. I’m an experienced baker, and this was definitely a bust.
My sourdough discard was on the thicker side, so that wasn’t the problem. Disappointing.
Hey there! Could I bake this in a
Bundt pan?
Yes! 🙂 you’d want to increase the amounts a bit, maybe 1.5. there’s a slider on the recipe you can use to change the serving size
Looks amazing! Is there anyway to long ferment the batter before baking?
Hi Hanna! I’ve never done it only because I worry about the lemon turning bitter. Maybe if you mixed it without the lemon, t hen added that right before baking?
