These sourdough berry muffins taste just like they came from a bakery—soft, fluffy, and packed with juicy berries! The first time I made them, I had three straight out of the oven, and my three-year-old ate four! They’re just that good. Whether you use fresh or frozen berries, these muffins turn out beautifully every time. If you use frozen berries (which I often do), they may tint the batter a little purple, but trust me, that only makes them more fun!

What is a Sourdough Starter?
A sourdough starter is a fermented mixture of flour and water that naturally cultivates wild yeast and beneficial bacteria. It’s used as a natural leavening agent in sourdough bread and other baked goods, adding a slightly tangy flavor and enhancing texture. In this recipe, we’re using sourdough discard—the portion of starter that is removed when feeding a starter—to add moisture, depth of flavor, and a subtle tang to the muffins without the need for extra fermentation time. This is the guide I used to start my sourdough starter years ago (I can’t believe it’s been YEARS! People often name their starters, as I done with mine, his name is Crust Hemsworth lol).
What to Do If You Don’t Have a Sourdough Starter
If you don’t have a sourdough starter, you can substitute the ½ cup of sourdough discard with an additional ¼ cup of all-purpose flour and ¼ cup of buttermilk or milk + ½ teaspoon vinegar/lemon juice. This will help maintain the moisture and slight tang that sourdough discard provides.

Tips for Success
- Use room temperature ingredients – This helps everything mix together smoothly.
- Don’t overmix the batter – Overmixing leads to dense muffins instead of light and fluffy ones.
- Toss frozen berries in flour – This prevents the berries from sinking and helps minimize color bleeding.
- Use aluminum-free baking powder – Some people find that baking powders containing aluminum can leave a slightly metallic taste.
- Let them cool slightly – These muffins are amazing warm but will firm up as they cool.

Customizations
- Swap the berries – Try blackberries, chopped strawberries, or even a mix of berries.
- Add a crumble topping – Mix 2 tablespoons flour, 2 tablespoons sugar, and 1 tablespoon butter until crumbly and sprinkle on top before baking.
- Make them citrusy – Add the zest of a lemon or orange for a fresh, bright flavor.
- Add nuts or chocolate – Chopped nuts or white chocolate chips would be a delicious addition.
Serving Suggestions
These muffins are perfect for breakfast, brunch, or an afternoon snack. Serve them warm with a little butter or a drizzle of honey. Pair with coffee or tea for a cozy treat!

Storing and Freezing
- Room Temperature: Store in an airtight container for up to 3 days.
- Refrigerate: If storing longer, keep them in the fridge for up to a week.
- Freeze: Wrap muffins individually in plastic wrap and place in a freezer bag. They’ll stay fresh for up to 3 months. Thaw at room temperature or warm in the microwave.
Enjoy these delicious sourdough berry muffins—they’re bakery-quality, simple to make, and absolutely irresistible!

- Mix the batter – Pour the wet ingredients into the dry ingredients and gently mix until just combined. Do not overmix.
- Fold in the berries – Gently stir in the fresh or frozen berries. If using frozen berries, toss them in a little flour to prevent excess bleeding into the batter.
- Fill muffin cups – Divide the batter evenly between the muffin cups, filling them about ¾ full.
