These made-from-scratch fluffy Sourdough Blueberry Muffins are tender, moist, and a great way to use your leftover sourdough starter. Each bite is filled with blueberry flavor and is topped with a sweet, buttery streusel topping.
Blueberry sourdough muffins are a family favorite around here! Since I had some leftover sourdough bread starter, I thought it would be a delicious way to try something new by adding it to my muffin batter! These are great for breakfast, dessert, or afternoon snacks. Plus they freeze well, so prepping is a breeze.
If you have leftover blueberries, make a batch of cream cheese filled blueberry lemon bread. It’s delicious and an easy brunch recipe. We also love making blueberry French toast casserole. As far as desserts go, I recommend blueberry lemon blondies, and the cute little lemon blueberry bites.

🧁 Ingredients:
- Flour – we used all purpose flour
- Salt – deepens flavors
- Baking powder – helps the muffins to rise
- sourdough bread starter – adds a hint of sourdough flavor and gives a great texture, but does not help the muffins to rise
- Eggs – we used large
- Salted butter– once it’s melted, allow it to cool before adding it to the batter
- Sugar – granulated white sugar and brown sugar are needed
- Vanilla extract – adds a subtle hint of vanilla
- Milk – whole milk
- Blueberries – fresh blueberries if you have them
- Heavy whipping cream – can also use milk in its place

Substitutions and Variations
- Milk – we generally use whole milk for this recipe but 2% also works great too.
- Try to add in a little lemon zest into the batter or even into the streusel!
- Regular blueberry muffins – Instead of using the active sourdough starter, use 2 cups of flour and ½ cup of milk.
- Frozen blueberries – add the frozen berries directly to the batter from the freezer in place of fresh ones.
- Frosting – don’t want a streusel topping? Add a thin layer of blueberry buttercream frosting, or lemon buttercream frosting.
- Gluten-Free – the sourdough starter is made with whole wheat flour. However, if you want to make it gluten-free, just swap that for gluten-free whole-grain flour and that’s the only ingredient that needs swapping.
🔪 Instructions:
PREP: Line the muffin tin with liners or grease with non-stick cooking spray. Preheat the oven to 425 degrees.
Step 1: In a large bowl, whisk sourdough starter, eggs, melted butter, sugar, vanilla, and milk together.
Step 2: Remove a tablespoon of flour from the ½ cup and add it to a medium bowl with the blueberries. Stir to coat. Sift the flour, salt, and baking powder together.
Step 3: Mix the sourdough mixture wet ingredients with the dry ingredients.
Step 4: Fold blueberries into the muffin batter using a spatula or wooden spoon.
Pro Tip: Do not over-mix the batter. Combine the ingredients just until they are incorporated to prevent them from getting tough.
Step 5: Divide the batter between the paper liners.
Step 6: Mix the flour, baking powder, and sugars together.
Step 7: Use a fork or pastry blender to cut the butter into the flour mixture so crumbs form.
Step 8: Pour in the heavy cream and stir to make larger clumps.
Step 9: Sprinkle the crumb topping on each muffin. Add a few more blueberries if desired.
Step 10: Baked for 6-7 minutes in the preheated oven, then turn the oven down to 350 degrees and bake for another 18-20 minutes.
SERVE: Allow muffins to cool in the pan for 5 minutes, then transfer them to a wire rack to finish cooling.
Tips for Sourdough Blueberry Muffin Recipe
- Avoid over-mixing. This will yield dense muffins instead of tender and fluffy ones.
- Tossing the berries in flour keeps them from sinking to the bottom.
- If the topping gets too dark and the muffins still aren’t fully cooked, cover them with aluminum foil.
Fun Fact
Did you know that metalware interferes with the process of making a sourdough starter? You should always use glass or ceramic bowls and plastic or wooden utensils when making it.
Recipe FAQs
A sourdough starter is a fermented dough made of flour and water that is used to leaven bread dough. It is made by combining flour and water and allowing the mixture to sit at room temperature, which allows wild yeasts and bacteria in the environment to colonize and feed on the mixture. These microorganisms, along with those naturally present in the flour, produce lactic acid and acetic acid, which give sourdough its distinct sour flavor and aroma.
Keep the muffins in an airtight container for 2-3 days in the refrigerator or wrap them in plastic wrap and place them in a freezer bag to freeze for up to 1 month.
