This recipe makes one dozen large delicious blueberry discard muffins.

Ingredients

• Sourdough discard: Use your starter whether its more active or really hungry and runny. To get best results, weigh your ingredients with a kitchen scale. One cup of active starter with most likely weigh less than one cup of runny starter. If your starter is thicker, you may need to add more milk to thin out the batter.
• Baking powder & baking soda: Even though we’re using sourdough starter, discard is an unfed starter and won’t be enough to give these muffins the tall, fluffy texture they need. Baking powder and baking soda are still necessary for this recipe.
• Greek yogurt adds a really fluffy texture and flavor. You can swap it out with sour cream if you like.
• Blueberries: You can use either fresh or frozen blueberries.
• Sugar: These muffins are sweet and delicious. If you want to cut back on the sugar, you can decrease it by up to 25%. So instead of using 1 cup (200g) sugar, you could use 3/4 cup (150g). They’ll still be delicious, but just a bit less sweet.
• Lemon zest is optional but could provide a yummy flavor and slight tartness with these sweet discard muffins.

Steps for making Sourdough Blueberry Muffins

1. Make the crumb topping by combining the butter, sugar and flour together with a fork. Set it aside as you mix the muffin batter. The crumb topping will dry out as it sits, making it easier to sprinkle on top of the muffins later.
2. Prepare a muffin tin with muffin liners or spray with nonstick spray.
3. Combine the dry ingredients: the flour, sugar, baking powder, baking soda, and salt.
4. Combine the wet ingredients in a separate bowl: the melted butter, milk, eggs, sourdough starter discard, Greek yogurt, and vanilla.
5. Add the wet ingredients to the dry ingredients. Stir to combine. I love that this recipe comes together so quick and easy, and you can mix it by hand! Depending on how thick your batter is, you may need to add a bit more milk to thin it out. It needs to be a consistency that you can easily scoop into the muffin tin.
6. Fold in the blueberries. You can use either fresh or frozen blueberries.
7. Scoop the muffin batter into the muffin tin, filling each well with equal amounts of batter. Sprinkle the crumb topping generously over each muffin. Slightly press the crumb topping into the tops of the muffins to keep it in place as it bakes.
8. Bake at 350°F for 28-30 minutes. Allow the muffins to cool in the pan for 10 minutes before removing.
9. Serve and enjoy!

How to make sourdough discard muffins healthy

• Reduce the sugar by up to 25%. Use 3/4 cup sugar instead of 1 cup.
• Use Whole grains: Swap out some of the white flour for whole grain flour like whole wheat, spelt, or khorasan. Baking with whole grains gives your baked goods more nutrients and keeps your tummy fuller longer. It’s important to keep in mind, whole grain muffins will have a denser texture. The more whole grains you use, the less fluffy the muffins will be. When deciding how much whole grains to use, start by swapping out about 20% of the white flour. If you like the results and feel like you could go further, next time swap out 30%. See how far you can take it while maintaining a texture and flavor you and your family still enjoy.
• Add flax meal. Flax meal has lots of beneficial nutrients and can keep you fuller longer. I’d use 2 Tablespoons of flax meal for this muffin recipe.
• Use Greek yogurt instead of sour cream. Greek yogurt provides a good source of protein without as much fat.

Storing

Store the muffins in a zip top bag or airtight container for up to 3 days. You can also freeze them to enjoy later – get them out the of the freezer the night before and let them thaw overnight at room temperature. Freeze for up to 2 months. Reheat them in the microwave if you want to enjoy a warm muffin.
