Why use sourdough discard in baking
Sourdough discard adds moistness, depth of flavor, and a slight tang that sourdough is known for. When feeding your sourdough starter, you will “discard” a portion of it before adding in the flour and water. And while the discard is no longer ideal for leavening baked goods such as artisan sourdough bread or cinnamon rolls, you can use it in a variety of sourdough discard recipes, such as pancakes, cookies, biscuits, and crackers.
Important Ingredients & Substitutions
- Sour cream- The sour cream adds moisture and flavor to the muffins. If needed you could sub for greek yogurt in the recipe.
- Sourdough discard- You can use sourdough discard straight from the fridge or room temperature.
- Butter- Butter is added to the batter to add richness and a buttery flavor.
- Baking powder- The baking powder is the leavening agent used in the muffins.
- Flour– I use all-purpose flour in this recipe. You could replace some with whole wheat if you would like.
- Blueberries – You can use fresh blueberries or frozen blueberries in this recipe.
See all the ingredients and amounts in the recipe card below.
Helpful tools
Muffin Pan– You can use a greased muffin pan or use paper liners. Another option is to bake in a silicone muffin pan to easily pop out the muffins.
Kitchen scale or Measuring cups and spoons – the recipe has both grams and cups, so you can use either option. However, using a scale to weight ingredients always gives the most accurate results.
Cooling Racks – Using the wire rack for cooling allows the muffins to cool evenly. You’ll want to remove the muffins from the muffin pan after a few minutes to prevent the muffins from getting tough.
Instructions to make Sourdough Blueberry Muffins with Streusel Topping
Step 1: In a large mixing bowl, add the butter and sugar and beat until smooth.
Step 2: Add in the wet ingredients: milk, sour cream, sourdough discard, vanilla extract, and eggs. Whisk or stir to combine.
Step 3: Fold in the dry ingredients until the flour mixture is just combined. It’s okay if that batter is a little lumpy, you do not want to over mix.
Step 4: Add the blueberries to the batter. Since the batter is so thick you don’t have to worry about tossing the fruit in flour.
Step 5: Fold the blueberries in until just incorporated.
Step 6: Scoop ¹⁄₃ cup of batter into each muffin liner or greased muffin tin. This will make a total of 15 muffins.
Step 7: For the streusel, combine flour, cinnamon, and sugar in a bowl. Cut the cold butter into the mixture using your fingers or a pastry cutter until it forms coarse crumbs. Add about 1 tablespoon of streusel to each muffin, making sure it covers the top.
Step 8: Bake for 17–18 minutes or until a toothpick inserted into the center of a muffin comes out clean or with just a few crumbs.
Cool in the pan for a few minutes, then transfer muffins to a wire rack to cool completely.
Recipe Tips
- Do not overmix the batter. Only incorporate until the flour is just incorporated. Overmixing can cause the muffins to become tough.
- Once they are done baking let them sit in the pan for 5 minutes and then remove from the pan and place on a cooling rack to finish cooling.
Storage instructions
To store, add the muffins to an airtight container or bag. They can be stored on the counter for up to 5 days. To freeze, wrap them in plastic wrap or store them in a freezer bag for up to 3 months. To thaw, remove them from the freezer and let them thaw on the counter or put them in the microwave for a few seconds at a time until they are warmed through.
FAQ
Yes, you can substitute greek yogurt for the sour cream if you prefer.
Yes, this recipe can be made with either fresh or frozen blueberries. You do not need to defrost the blueberries before adding them to the batter. Simply add the frozen blueberries directly to the batter and bake.
Sure! Most of my quick breads take about an hour to 1 hour and 15 minutes at 350°F so this recipe should take about that time as well. It will be baked through when a toothpick comes clean. If the top gets too brown while baking you can add foil on top.
If your blueberries are sinking to the bottom, try tossing them with 1 teaspoon of the flour from this recipe. The coating of flour will help keep them from sinking. Although this batter is thick enough that you shouldn’t need to do that.
Yes, either active starter or discard will both work in this recipe.
If you want to try other variations of this muffin recipe, you can try using raspberries, blackberries, or a combination!

The best blueberry muffins I’ve ever had. Don’t understand for 4.5 stars rating.. it should be 5 stars. It’s really good and easy to make. Just follow the steps and there is no mistakes.
I sub the sour cream for Greek yogurt, and used light brown sugar and no vanilla extract.
The best, soft and nice crunchy crumbs muffin! Thank you
Thanks so much, Jana!
These are the best muffins I have ever made. Nice and moist on the inside, a little crusty on the top, perfect!
Thanks so much, Cheryl!
These have to be the best blueberry muffins I have ever made. They are so moist. Thought I would try swapping out some of the sour cream for lemon yogurt maybe adding a little less milk and adding lemon curd. Can’t wait to try this recipe again.
Ooo I love the idea of lemon yogurt. Let me know how it goes!
These are the best blueberry muffins. So moist and delicious- thank you for the recipe
I’m so glad you like them. Thanks for leaving a review!
I love this recipe! Can’t wait to try. Can frozen blueberries be subbed for fresh?
Yes!
10/10 a must !!!!
Yay, thanks Rosemaria!
I made these with a mixture of blueberries, raspberries and blackberries! They were so good. A huge hit with my family and coworkers. Thank you.
So happy to hear that, thank you for sharing!
I made them last night and they are very good, but super sweet! There is a LOT of sugar in these. I would cut back on that in the future. Was the butter suppose to be melted for the muffin mix? The receipe did not say.
Thanks for the feedback. In the muffin batter the butter should just be room temperature to cream with the sugar.
Can you use buttermilk in place of milk?
Yeah that should be fine!
These muffins are super easy to make and DELICIOUS!!
Thanks Cindy!
I made these muffins today….oh my! They are delicious. I used my starter that was 2 days old, instead of discard starter. These muffins are very moist. I used a muffin pan that makes a larger muffin, so I got 9 muffins. They took about 20 minutes to bake. I made a notation in your cookbook as to the adjustments I made. Next up are the banana choc chips sourdough muffins. So happy with your recipes!!
Thanks so much, Sue! I’m so happy to hear that.
What adjustment should be made to do these as jumbo muffins instead?
Likely just the baking time. I would start with a few extra minutes and see how they are doing and adjust timing as needed. If the tops are getting too brown you can place foil overtop to prevent the streusel from burning.
