🫐 The Story Behind These Muffins
"This is maybe the best sourdough discard blueberry muffin recipe out there." 🫐✨
That's a bold claim – but after tasting these muffins, I'm willing to make it. Fluffy, tangy, bursting with blueberries, and with that perfect domed top that makes a muffin look like it belongs in a bakery window. And the best part? They use up your sourdough discard, so nothing goes to waste.
If you've been hoarding sourdough discard in your fridge, wondering what to do with it, this is your sign. These muffins are the perfect combination of sweet, tangy, and tender – with a texture that's light and moist, not dense or gummy. They're quick to make, use up your discard, and turn a simple breakfast into something extraordinary.
💬 The secret: The acidity in sourdough discard reacts with the baking soda to create the lightest, fluffiest muffins you'll ever eat – and that tangy flavor is absolutely irresistible!

📦 Ingredients
For the Muffins:
- 🌾 1½ cups (180g) all-purpose flour – spooned and leveled
- 🥣 1 cup (240g) sourdough discard – unfed, straight from the fridge
- 🍬 ¾ cup (150g) granulated sugar
- 🥛 ½ cup (120ml) buttermilk – or regular milk with 1 tsp vinegar
- 🫒 ⅓ cup (80ml) vegetable oil – or melted butter
- 🥚 1 large egg – room temperature
- 💨 1 tsp baking powder
- 💨 ½ tsp baking soda
- 🧂 ½ tsp salt
- 🫐 1½ cups blueberries – fresh or frozen (if frozen, don't thaw)
For the Topping (Optional):
- 🍬 1-2 tbsp turbinado sugar
- 🌿 ½ tsp cinnamon
📝 Step-by-Step Instructions
Step 1 – Preheat and Prepare
- Preheat your oven to 375°F (190°C).
- Line a 12-cup muffin tin with paper liners or grease thoroughly.
Step 2 – Mix Wet Ingredients
- In a large bowl, whisk together:
- Sourdough discard
- Buttermilk
- Vegetable oil
- Egg
- Sugar
Step 3 – Add Dry Ingredients
- Sprinkle the flour, baking powder, baking soda, and salt over the wet mixture.
- Fold gently until just combined – a few lumps are fine. Overmixing will make tough muffins.
Step 4 – Add Blueberries
- Gently fold in the blueberries.
- If using frozen blueberries, toss them in a tablespoon of flour first to prevent them from sinking to the bottom.
Step 5 – Fill Muffin Tins
- Divide the batter evenly among the 12 muffin cups.
- Fill them almost to the top – this helps create that beautiful domed top.
Step 6 – Top and Bake
- Sprinkle with turbinado sugar and cinnamon if desired.
- Bake for 18-22 minutes, or until a toothpick inserted in the center comes out clean.
Step 7 – Cool
- Let the muffins cool in the pan for 5 minutes.
- Transfer to a wire rack to cool completely.
💡 Pro tip: For extra bakery-style domes, let the batter rest in the muffin tin for 10-15 minutes before baking. This allows the gluten to relax.
🔧 Troubleshooting – What If Something Goes Wrong?
- 😟 Dense, heavy muffins: Overmixed batter – mix just until combined, lumps are okay
- 😟 Flat tops: Batter too wet – reduce buttermilk by 2 tbsp next time
- 😟 Muffins stick to liners: Too much moisture – let cool completely before peeling
- 😟 Blueberries sunk to bottom: Berries too heavy – toss frozen berries in flour before adding
- 😟 Sour taste too strong: Discard was very old – use fresher discard or add 1 tbsp more sugar
- 😟 Muffins are dry: Overbaked – check at 18 minutes; don't overbake
- 😟 No domed top: Oven too cool or not enough batter – fill cups almost to the top; check oven temp
🫐 Blueberry Tips & Variations
Blueberry Tips:
- 🫐 Use fresh if possible: Better texture and flavor
- 🫐 If using frozen, don't thaw: Prevents bleeding and sinking
- 🫐 Toss in flour: Keeps berries suspended in batter
- 🫐 Reserve a few: Place a few berries on top before baking for a beautiful look
Delicious Variations:
- 🍋 Lemon Blueberry: Add zest of 1 lemon and 1 tbsp lemon juice
- 🍊 Orange Blueberry: Add zest of 1 orange and ½ tsp orange extract
- 🌿 Cinnamon Blueberry: Add 1 tsp cinnamon to the batter
- 🧁 Streusel Topping: Mix ¼ cup flour, ¼ cup sugar, and 2 tbsp cold butter for a crumb topping
- 🫐 Mixed Berry: Replace half the blueberries with raspberries or blackberries
