Oatmeal Strawberry Muffins
These sourdough oatmeal strawberry muffins are the perfect balance of wholesome and fruity. Made with fresh strawberries, hearty oats, and sourdough discard (or active starter), they offer a delicious way to reduce starter waste while creating a tender, flavorful muffin perfect for spring.
Whether youâre a seasoned sourdough baker or just looking for a nutritious breakfast treat, these muffins will quickly become a favorite in your kitchen.


Strawberry Muffins with Sourdough Discard
Why use sourdough in muffins? Sourdough isn’t just for bread! Incorporating sourdough starter or discard into muffins enhances flavor and texture while making them easier to digest.
Sourdough naturally contains lactic acid bacteria, which break down gluten, fructans, and phytic acid, making baked goods easier to digest. This can be especially beneficial for those with gluten or FODMAP sensitivities.
Unlike traditional sourdough bread, muffins arenât typically long-fermented, but you can ferment the batter overnight in the fridge for even better digestibility. Mix the batter, cover it, and refrigerate it overnight before baking.


The Key to Fluffy, Moist Muffins: Don’t Overmix!
One of the most important muffin-making tips? Avoid overmixing the batter.
When you overmix, you develop the gluten strands in the flour too much, leading to dense, chewy muffins instead of light, tender ones.
How to Mix Muffin Batter Properly:
- Add the fresh strawberries in with the dry ingredients (trust me).
- Gently fold the wet and dry ingredients together.
- Stop mixing when you see some streaks of flourâa few lumps and dry spots is ideal!
My other muffin baking tip is always to use a thin metal aluminum muffin tin with paper liners. A metal muffin tin works way better than a silicone muffin pan.

Why Fresh Strawberries Work Best in Muffins
Using fresh strawberries instead of freeze-dried or dehydrated ones gives these muffins a juicy, naturally sweet burst of flavor.
- Fresh strawberries add moisture and a soft, jammy texture to each bite.
- Chop them into small pieces so they distribute evenly throughout the batter.
- Toss them with the dry ingredients before mixing the batter to prevent them from sinking to the bottom.
