A simple discard recipe for sourdough blueberry muffins, with a sweet streusel topping and plenty of blueberries. Made in one bowl, these can easily be made dairy free.
We have one sourdough discard muffin recipe already in the books – our sourdough morning glory muffins – but these one-bowl blueberry coffee cake muffins are sweeter, more delicate, and perfect for afternoon tea or coffee.
It’s blueberry season right now, but these can be made with either fresh or frozen blueberries, so they can be enjoyed year round. So if you have too much extra sourdough starter lying around, put your discard to use in some muffins!

Ingredients
- Milk (or non-dairy milk)
- Sourdough starter discard
- Sunflower or other vegetable oil (see substitutions)
- Eggs
- Vanilla extract
- All-purpose flour
- Sugar
- Baking powder
- Cinnamon
- Sea salt
- Fresh or frozen blueberries
- Butter or coconut oil (for streusel)
Method
Start by making the streusel topping. Place the flour, sugar, cinnamon, and butter (or coconut oil/milk) into a medium bowl and use your hands to mix. It should be crumbly, with some larger pieces, when it’s ready. Set aside.
Preheat the oven and line (or grease) a 12-cup muffin tin.
Whisk the milk, discard, oil, eggs, and vanilla together in a large bowl. Add the flour, sugar, baking powder, cinnamon, and salt, and mix until just combined. There shouldn’t be any streaks of flour visible, but try not to over mix.
Add the blueberries to the muffin batter and carefully fold them in with a wooden spoon or spatula.
Spoon the batter evenly into each muffin cup, then top with the streusel topping. It might seem like a lot, but as the muffins rise you want enough streusel for each one!
Bake the muffins for about 22 minutes. Do the toothpick test to make sure they’re done before taking them out of the oven, then let them rest in the muffin tin for a few minutes before cooling fully on a rack.
Tips and Notes
If using frozen berries, use them directly from the freezer to reduce the purple colour leaching into the muffin batter too much. This batter is thick enough that the berries won’t sink to the bottom, so there’s no need to coat in flour beforehand.
The muffins are on the sweet side with the addition of streusel, so if you prefer a less-sweet muffin, you may want to leave the topping off. Or, if making the streusel seems like a bit much, you can also sprinkle the tops of each muffin with a little sugar instead.
We prefer using muffin liners for fruit muffins because added fruit can sometimes burn when it’s in direct contact with the muffin tin.
Substitutions
As mentioned above, both fresh and frozen berries work well. We recommend wild blueberries for their small size (more blueberries in each bite) but it doesn’t matter. Raspberries and blackberries also work well.
Sunflower oil is great here for its neutral taste, but avocado oil, organic canola oil, and grape seed can all be used instead. Melted butter will likely be fine but we haven’t tested these with it.
The recipe card provides instructions for making the streusel dairy free, and the muffins can be made with dairy-free milk (like oat or almond) if you prefer. Don’t like cinnamon? We recommend using half the amount cardamom instead.
If you want a slightly more wholesome muffin, whole wheat pastry flour can be used instead of all-purpose.

Recipe
Sourdough Blueberry Muffins with Cinnamon Streusel
A simple discard recipe for sourdough blueberry muffins, with a sweet streusel topping and plenty of sweet blueberries. These can easily be made dairy free.
Ingredients
Sourdough Blueberry Muffins
- ¾ cup (180 ml) milk
- ½ cup (125 ml) sunflower oil
- ½ cup (100 g) sourdough discard
- 2 large eggs
- 1 tsp vanilla extract
- 2 cups (300 g) all-purpose flour
- ½ cup (100 g) sugar
- 2 ½ tsp baking powder
- 1 tsp cinnamon
- ½ tsp sea salt
- 1 cup (125 g) wild blueberries, fresh or frozen
Cinnamon Streusel
- 1 cup (150 g) all-purpose flour
- ⅓ cup (70 g) sugar
- 1 tsp cinnamon
- ⅓ cup (80 g) butter
Instructions
- Start by making the streusel. Mix the flour, sugar, and cinnamon in a medium bowl, then add the butter. Use your hands to mix until a crumbly mixture forms, then set aside.
- Preheat the oven to 350°F (180°C) and line or grease a 12-cup muffin tin.
- In a large bowl, whisk the milk, oil, discard, eggs, and vanilla until fully combined and slightly frothy.
- Add the flour, sugar, baking powder, cinnamon, and salt to the bowl. Use a wooden spoon to mix until no streaks of flour remain in the bowl.
- Add the blueberries to the muffin batter and carefully fold them in to incorporate throughout.
- Spoon an equal amount of batter into each muffin cup, then cover each with the streusel topping.
- Bake the muffins for 22-24 minutes, or until the top is lightly golden and a toothpick inserted into the centre of a muffin comes out clean.
- Cool the muffins in the tin for five minutes before removing and cooling fully on a rack. The muffins will keep for a couple of days at room temperature, but are best on the day they're baked.
Notes
To make the streusel dairy free, use ¼ cup (60 g) coconut oil and 1 tbsp non-dairy milk in place of the butter.

I did not see the temperature you are supposed to bake the muffins at. Did I miss it??
Thanks, Ruth Setacci

Hi Ruth, were you looking at the recipe card at the bottom of the post or the ingredient/method run through in the post body? Please be sure to look at the card for the correct amounts of each ingredient, and the baking temperature in step two (350F/180C) to make sure the muffins turn out well. Hope that helps!
