How to Make Sourdough Oatmeal Bran Muffins Step-by-Step
Step 1: Mix Your Magic
Grab a big mixing bowl and combine the applesauce, milk, sourdough discard, honey, and eggs. Stir in the bran, oats, whole wheat flour, baking powder, salt, and cinnamon. Finally, fold in the chocolate chips if you’re feeling fun (you are).
This is the beauty of sourdough oatmeal bran muffins—no need for fancy equipment or precise technique. Just a big spoon and some good vibes.
Step 2: Overnight Oats Transformation
Cover your bowl and let the mixture rest in the fridge overnight. The oats will soak, the sourdough will ferment, and the whole thing will become a cozy batter ready for baking.
Overnight, these sourdough oatmeal bran muffins become a flavor-packed powerhouse that’s waiting for you when you wake up.

Step 3: Bake to Perfection
In the morning, preheat your oven to 350°F (175°C). Grease or line a muffin tin, and fill each cup ¾ full with your now-ready batter.
Bake for 22–25 minutes or until the tops are golden and a toothpick comes out clean.
Pro Tip: Your kitchen will smell like heaven. You might not even need coffee (but please still have coffee).

Sourdough Oatmeal Bran Muffins FAQs
Can I freeze sourdough oatmeal bran muffins?
Absolutely. Cool them completely, then pop them in a zip-top bag and freeze for up to 3 months. Reheat in the microwave or oven for a quick breakfast.
Can I use oat bran instead of wheat bran?
Yes, oat bran works perfectly and gives the muffins a slightly nuttier taste. It keeps the sourdough oatmeal bran muffins soft and fiber-rich.
How do I make them sweeter?
The honey already adds a natural sweetness, but feel free to stir in raisins or a few extra chocolate chips. Your kitchen, your rules.
Can I skip the overnight part?
Technically, yes. But allowing the oats to soak overnight improves both texture and flavor. Your sourdough oatmeal bran muffins will thank you.
