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!)

These sourdough banana muffins are just like our sourdough banana bread recipe, but they are in muffin form. They are soft and fluffy but also hearty and satisfying. They have the right balance of tangy sweetness throughout.
Bonus: This sourdough muffin recipe is ready to enjoy in only 30 minutes.
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!

How to Make Sourdough Banana Muffins
Preheat the oven to 350ºF. Lightly grease your muffin cups or line with muffin pan liners.
Combine the butter and sugar in a large bowl. Mix by hand until smooth, about 2 minutes. Or use a stand or hand mixer on low speed for 1-2 minutes, until the mixture is smooth.

Stir in mashed bananas, honey, vanilla extract, sourdough starter, baking powder, baking soda, eggs, and salt. Mix until smooth. Then add all purpose flour and nuts or chocolate chips, if using.
Pour the banana bread mixture into the prepared muffin pan, filling almost to the top. Then let rest at room temperature for 10 minutes.

Bake for 20-25 minutes, or until a toothpick inserted into the middle of the muffin comes out clean.
Allow bread loaf to cool for 5 minutes in the muffin tin or cooling rack before removing and serving.

Frequently Asked Questions
Traditional sourdough starter is made with wheat flour. However, you can use a gluten-free starter and a GF-friendly all-purpose flour substitute.
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!
Keep stored in an airtight container or wrapped in plastic at room temperature for up to 5 days.
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.

This is the best banana bread I have ever made! I didn’t have any butter so I used coconut oil. I had to bake them a little longer (25-30 minutes) but they turned out amazing. Thank you for the wonderful recipe!
Samantha says
So, I started making these this evening. Added an extra banana and mixed everything together. I poured them into my muffin pan and then realized I forgot to add the 2 eggs. They still turned out delicious. Thank you for a great recipe.

Hi! You have eggs listed in the ingredients but not in the instructions. Do you add eggs?
Renae says
Of course! I just checked the recipe instructions and the eggs are added in step 3 (right after the honey).
