Why We Love Sourdough Starter Banana Muffins

Muffins are a delicious way to start or end the day. They are perfect for breakfast, snacks, or dessert. No matter what time it is, muffins are always a good choice!

And banana muffins are a classic. They’re loaded with the delicious baked banana flavor in every bite, and they’ll always put a smile on your face anytime you want something a little sweet.

We’ve made classic muffins with banana even better by adding a homemade sourdough starter. Also, the crumb is moist and spongey, and the sourdough tanginess really makes it stand out.

Plus, the extra enzymes in the sourdough help to keep the muffins fresher for longer and are great for gut health. (Hooray for foods that are good for you and actually taste good!)

You can also add your favorite goodies, like baking chips or chopped nuts to these uniquely delicious and perfectly tangy treats.

Sourdough starter banana muffins are good to make ahead and have during the week. They are also good to bake last minute for brunches, picnics, and potlucks. You can also make a quick batch whenever you get a craving!

Frequently Asked Questions

How do you make gluten-free sourdough muffins?

Traditional sourdough starter is made with wheat flour. However, you can use a gluten-free starter and a GF-friendly all-purpose flour substitute.

What mix-ins go well in sourdough discard banana muffins?

Chopped dark chocolate or chocolate chips, peanut butter chips, or butterscotch chips are all great to make extra sweet baked goodies. Or add in nuts like chopped walnuts or almonds. You can even mix in a bit of both!

How long do homemade banana sourdough muffins last?

Keep stored in an airtight container or wrapped in plastic at room temperature for up to 5 days.

How do you freeze muffins?

Sourdough discard muffins are great to freeze. Wrap the muffins individually in plastic wrap and then place them all in an airtight plastic zipper bag. Keep in the freezer for up to 3 months.
