Common Questions:
What is Sourdough Discard?
Sourdough discard is simply an “inactive” sourdough starter. This means that the sourdough has become bubbly then fallen back down. At this point a starter needs to be fed and some needs to be removed to make room for more.
Can Sourdough Discard Be Saved?
Fresh sourdough discard is always best but you can save it in an airtight container in the fridge for a week if needed. I haven’t tried freezing my sourdough discard but many people say it can freeze for months. Just let the discard defrost before using it in a recipe.
Are Sourdough Muffins Fermented Overnight?
These sourdough discard muffins can be fermented overnight in the fridge or baked right away, so it’s up to you!

Sourdough Discard Muffins Ingredients:
All purpose flour: I use an organic all purpose flour. I don’t reccomend swapping whole wheat flour because it’s not a 1:1 replacement.
Cane sugar: These muffins have just the right level of sweetness in my opinion. You can always swap the cane sugar for more coconut sugar but be aware that it will darken the color!
Coconut sugar: This sugar has more of earthy flavor along with its sweetness. You can replace this ingredient with brown sugar if you prefer!
Baking powder: A rising agent in this recipe.
Baking soda: Another rising agent that works along with the baking powder and sourdough discard to make a fluffy, tall muffin.
Sea salt: This brings out the other flavors in this recipe.
Lemon zest: I love adding lemon with blueberry to make the perfect combo. If you want, you can leave the lemon zest out.
Sourdough discard: I use my sourdough discard at 50% hydration (which means I feed my starter with 2 parts flour and 1 part water). This creates a thicker starter and I prefer that for these muffins.
Coconut oil: In this recipe we use coconut oil that has been melted and cooled to room temperature. This ensures the oil won’t solidify when added to cold ingredients.
Eggs: A binder in this recipe that helps the muffins bake through.
Full fat coconut milk: This comes in a can and has a very thick consistency. I have not tried this, but you might be able to substitute sour cream. Let me know if you try that subsitution and how it goes.
Blueberries: I have tried fresh and frozen in these muffins and both work, but frozen will turn the batter a bit blue. If using frozen, I recommend taking out of the freezer and adding immediately before baking.

Sourdough Discard Blueberry Muffins Instructions:
- Start by mixing your dry ingredients in a large bowl. This includes the flour, cane sugar, coconut sugar, baking powder, baking soda, sea salt and lemon zest.
- In a separate mixing bowl, mix together sourdough discard, melted coconut oil, eggs and full fat coconut milk.
- Mix the wet and dry ingredients together until well combined.
- If you want to let your muffins ferment overnight, cover the bowl with a plate or lid and place in the fridge. The morning you’re ready to bake them, take your muffin batter out of the fridge and allow it to come to room temperature for 2-3 hours. (Skip step 4 if baking right away).
- Preheat your oven and line muffin tin with liner cups (I make my own with a square sheet of parchment paper).
- Gently fold bluerries into the muffins batter.
- Divide batter among 12 muffin cups or 10 muffin cups for larger muffins.
- Bake for 25-35 minutes or until an inserted toothpick comes out clean.

Equipment for Sourdough Muffins:
There are just a few pieces of kitchen equipment you’ll need for these muffins. I always use and recommend materials like stainless steel, glass or ceramic for healthy cooking and here are some great options you can use for this recipe and many others!
- This glass mixing bowl with a lid is similar to the one I use daily.
- I use a stainless steel muffin pan and it works amazingly well!
- If you’re wanting a premade option for natural muffin liners, here some super cheap ones.
