A Happy Little Accident
I first made these muffins by mistake. My sourdough starter was extra bubbly one morning. I had some blueberries about to go soft. So I just started mixing. I still laugh at that.
The smell from the oven was amazing. It was sweet and tangy all at once. My grandson said they were the best I ever made. That is why this matters. The best things often come from happy accidents.
Why Sourdough Makes It Special
Sourdough isn’t just for bread. It gives these muffins a little tang. It makes them soft and keeps them moist for days. Doesn’t that sound nice?
Using your “discard” starter is a smart trick. It gives flavor and stops you from wasting any. Fun fact: The sourdough helps break down the flour. This can make it easier for some people to digest. What is your favorite way to use sourdough discard?
The Secret to a Perfect Rise
Do not over-mix the batter. A few lumps are just fine. If you mix too much, the muffins get tough. We want them light and fluffy.
Starting with a hot oven is the real secret. That first blast of heat makes them puff up tall. Then you turn it down to bake the inside. Have you ever tried this trick with other muffin recipes?
A Tip for Your Berries
No one wants all the blueberries at the bottom. I learned a simple trick from my mother. Just toss them in a tiny bit of flour first.
This little coat of flour helps them stay put. They will be scattered all through your muffin. That is why this matters. Every single bite will be full of juicy berry flavor.
For the Patient Bakers
If you have more time, try the long ferment. You mix the dough the night before. Then you let it sit on the counter. It develops a deeper, richer taste.
The dough will be thick in the morning. That is normal. It makes the muffins feel more special. It is like a gift from past-you to present-you. Will you try the quick version or the overnight one first?

My Favorite Sourdough Blueberry Muffins
Oh, the smell of these muffins baking. It reminds me of my own grandma’s kitchen. She always said a good muffin should feel like a warm hug. I think she would have loved this recipe. It uses our sourdough starter discard. That means nothing goes to waste.
This is a simple way to make something special. You probably have everything you need right now. Let’s get our bowls ready. I’ll walk you through it, step by happy step.
Step 1: First, wake up your oven. Turn it to 425 degrees. This gets it nice and hot. A hot oven gives the muffins a beautiful rise. Then, get your muffin tin ready. I like to grease mine with a little butter. It makes them golden and crisp.
Step 2: Grab a medium bowl for your dry things. Whisk the flour, salt, baking powder, and baking soda together. This makes sure everything is friendly. No one wants a bite of just baking soda! Set this bowl aside for now.
Step 3: Now for the fun, wet ingredients. In a big bowl, mix the melted butter and sugar. Doesn’t that smell amazing? Then add your vanilla and sourdough starter. Give it a good stir. Lastly, crack in your eggs, one at a time.
Step 4: Time to bring the two bowls together. Slowly add the dry mix to the wet mix. Stir it until it’s just combined. A few lumps are perfectly fine, I promise. (My hard-learned tip: over-mixing makes tough muffins. Be gentle!).
Step 5: Toss your blueberries with a tiny bit of flour. This little trick stops them from sinking. Gently fold them into your batter. You can bake them now, or let the bowl sit in the fridge. This rest makes the flavor even better.
Step 6: Spoon the batter into your muffin tin. Fill each cup about two-thirds full. Now, into the hot oven they go! Bake at 425 for 5-6 minutes. Then, without opening the door, turn it down to 350. Bake for 13-15 more minutes.
Step 7: Are they done? A toothpick poked in the center should come out clean. Let them cool in the pan for a bit. I know, it’s hard to wait! The smell is just wonderful. What’s your favorite thing to bake on a cozy morning? Share below!

How to Serve Your Masterpiece
A warm muffin is a joy all by itself. But sometimes, you want to make it a little event. I love setting a pretty plate for my afternoon tea. It makes an ordinary day feel special.
For a lovely breakfast, slice a muffin in half. Toast it lightly and spread with creamy butter. The melted butter on the warm crumb is divine. You could also add a dollop of Greek yogurt on the side. It’s a perfect, creamy contrast.
What to drink? A cold glass of milk is a classic for a reason. It’s my go-to. For the grown-ups, a hot cup of coffee pairs beautifully. The bitter coffee and the sweet muffin are best friends. Which would you choose tonight?

Keeping Your Muffins Happy and Fresh
Let’s talk about keeping your muffins tasty for days. Cool them completely first. Then pop them in an airtight container. They will stay fresh on your counter for about two days.
For longer storage, the freezer is your best friend. I wrap each muffin tightly in plastic wrap. Then I tuck them all into a freezer bag. I remember my first batch getting a little dry. Now I never skip the wrapping step.
To reheat, just warm a muffin in the microwave for 15 seconds. It will taste like it just came out of the oven. Batch cooking like this saves you time on busy mornings. It means a warm breakfast is always minutes away.

Simple Fixes for Common Muffin Troubles
Sometimes baking can be tricky. But do not worry. I have some easy fixes for you. If your blueberries sink, just toss them in a teaspoon of flour first. This little coat helps them stay put in the batter.
I once mixed the batter too much. The muffins came out tough and dense. Now I mix until the flour is just combined. This matters because gentle mixing keeps your muffins light and soft.
If your muffins are pale, try the temperature trick. Start hot at 425 degrees, then lower it. This gives them a beautiful rise and a golden top. A nice color makes the muffins look as good as they taste.
Fun fact: The burst blueberries create little pockets of sweet, tangy jam inside!

Tangy Sourdough Blueberry Muffin Recipe
Ingredients
Instructions
- Preheat the oven to 425 degrees.
- Grease muffin tin wells or line with paper liners.
- In a medium bowl, whisk together the flour, salt, baking powder, and baking soda. Set aside.
- In a separate large bowl, whisk together melted butter, sugar, vanilla, and sourdough starter.
- Lastly, incorporate one egg at a time.
- Gradually add dry ingredients to the wet ingredients and mix until just combined. Don’t over-mix the batter or you could end up with a tough muffin.
- Gently fold the blueberries into batter. To prevent the blueberries from sinking to the bottom of the muffins, you could dust 1 tsp of flour over the blueberries and stir before folding them into the batter.
- Optional: Allow the mixture to sit in the fridge for one hour.
- Spoon the batter into the muffin tins.
- Bake in a preheated oven at 425 for 5-6 minutes, then drop the oven temperature to 350 and continue to bake for 13-15 minutes. This helps capture the rise while also baking through.
- Test muffins with a cake tester. Allow to cool.
Notes
- For a long-fermented version, combine melted butter, sugar, sourdough starter, and flour the night before. Let ferment for 8-24 hours, then proceed with adding the remaining ingredients and baking.
