If you bake sourdough bread at home, you know that sourdough discard often piles up. Instead of throwing it away, you can turn this leftover starter into something delicious. These sourdough discard blueberry muffins are moist, flavorful, and packed with wholesome ingredients. They make a perfect breakfast treat or snack, and they help reduce food waste by using sourdough discard in a tasty way.

Why Use Sourdough Discard in Muffins?
Sourdough discard is the portion of starter you remove before feeding your sourdough culture. It contains natural yeast and bacteria that add a subtle tang and depth of flavor to baked goods. Using discard in muffins:
Adds a gentle sour note that balances sweetness
Improves texture, making muffins tender and moist
Reduces waste by putting discard to good use
Provides some prebiotic benefits from the natural fermentation
This recipe combines sourdough discard with rolled oats, blueberries, and a hint of cinnamon for a wholesome muffin that’s both satisfying and nutritious.
Ingredients
This recipe makes 12 large muffins or 24 small ones.
Here’s what to gather:
Dry Ingredients
300g all-purpose flour
100g rolled oats
200g white sugar
100g brown sugar
4 tsp baking powder
1 tsp baking soda
½ tsp salt
1 tsp cinnamon
1 tbsp cornstarch
3 tbsp hemp seeds
2 cups frozen blueberries
Wet Ingredients
100g sourdough discard
113g melted butter
113g melted coconut oil
90g plain Greek yogurt
2 tsp vanilla extract
4 large eggs
3-5 tbsp cold water (to thin batter as needed)
Optional Topping
113g melted butter
100g brown sugar
100g rolled oats
½ tsp cinnamon
Steps to Follow:
Follow these steps for perfect muffins every time:
Preheat oven to 350°F (175°C). Line muffin tins with paper liners or grease well.
Mix dry ingredients: In a large bowl, combine flour, oats, sugars, baking powder, baking soda, salt, cinnamon, cornstarch, and hemp seeds. Stir well.
Add blueberries: Gently fold in frozen blueberries to keep them from breaking apart.
Combine wet ingredients: In a separate bowl, whisk melted butter, coconut oil, Greek yogurt, vanilla, eggs, and sourdough discard.
Mix wet and dry: Pour wet mixture into dry ingredients. Stir gently until just combined. Add cold water a tablespoon at a time if batter feels too thick.
Fill muffin tins: Spoon batter into prepared tins, filling about ¾ full.
Add topping (optional): Mix melted butter, brown sugar, oats, and cinnamon for the topping. Sprinkle evenly over muffins.
Bake for 30-35 minutes or until muffins are golden brown and a toothpick inserted comes out clean.
Cool on a wire rack before serving-try and resist until cool of you can!
Tips for Best Results
Use frozen blueberries to prevent them from sinking to the bottom.
Don’t overmix the batter; a few lumps are okay. Overmixing can make muffins tough.
Adjust water amount based on batter consistency; it should be thick but scoopable.
If you don’t have hemp seeds, you can substitute with chia or flax seeds for extra nutrition.
These muffins freeze well. Wrap individually and thaw at room temperature or warm in the oven.
Health Benefits of Sourdough Discard
Using sourdough discard in baking offers some health perks:
Improved digestion: The natural fermentation process breaks down gluten and phytic acid, making nutrients easier to absorb.
Prebiotic effects: The beneficial bacteria in sourdough support gut health.
Lower glycemic index: Sourdough fermentation can reduce the impact on blood sugar compared to regular baked goods.
Reduced food waste: Repurposing discard helps minimize kitchen waste and supports sustainable cooking.
While these muffins are a treat, they also bring some of these benefits thanks to the sourdough discard and wholesome ingredients like oats and hemp seeds.
