Highlights of Sourdough Discard Muffins
Tender. Fluffy. The magic is in the discard! Save it after feeding your Sourdough Starter, then hold on to the discard and repurpose it. Here are three reasons why sourdough starter discard is fabulous in baked goods:
- Sourdough discard has a tenderizing effect when combined with other leavening agents in gluten containing recipes making these banana muffins extra soft and tender.
- Sourdough containing recipes offer a little longer shelf life compared to its non sourdough counterparts.
- Using sourdough discard in recipes is a delicious way to maintain a no waste sourdough starter.
- Sourdough adds a subtle tangy flavor to any baked goods recipe!
These sourdough muffins aren’t very sour, however, as the sourdough flavor is subtle. But, the magic can be found in their tender and fluffy texture.
Quick Guide: How to Make this Sourdough Starter Banana Muffins Recipe
Sourdough discard banana muffins are easy to make with limited hands on time. In summary, here’s how to make em’ (see recipe card for details):
- First, toast the walnuts in a preheating oven. Chop and set aside.
- Second, in a medium bowl, whisk the flour, cinnamon, salt, baking powder and soda.
- Third, in a large bowl whisk together the sugar, eggs, oil, vanilla, mashed banana and discard.
- Next, mix the dry into the wet ingredients. Allow the batter to set for 15 minutes.
- Last, fold in the chopped walnuts, scoop and bake.
Resting the batter helps hydrate the flour and supports a lofty muffin. It’s worth the wait.
At a Glance: How to Bake Banana Muffins
You’ll need a twelve cup muffin pan and tulip cups to bake these sourdough muffins. This fluffy banana muffins recipe creates extra tall sourdough muffins so tulip muffin liners give them the support they need. Tulip cups can be purchased or follow the Kitchen’s DIY method for homemade!
You’ll notice a relatively high temperature for baking these sourdough starter discard banana muffins at 400F (205C), but as soon as the muffins are popped in the oven, the temperature is lowered to 375F (190C). This high starting temperature helps give these muffins their loft and a nice domed shape.
Pro Tip: Knowing the temperature of your oven is key for best baking outcome. Use an external oven thermometer (dial or digital) to know its true temperature and adjust as needed.
How to Make Sourdough Banana Muffins Healthy(ish)
I tested this recipe with both all purpose flour and whole wheat white flour. They both work beautifully! I prefer whole wheat white flour, due to the bonus of whole grain goodness, and its nutty flavor. But it’s good to know there’s another option if needed.
About Sourdough Discard
For this sourdough muffin recipe you’ll need half a cup of 100% hydration sourdough discard. It can be old or young, and pulled straight from the refrigerator. If it’s been hanging out in the fridge for a while (a few weeks or more), smell the discard. If it smells fruity and ripe, carry on with your recipe. However, if it smells off or stinky, toss it and create new sourdough discard.

How to Store Your Sourdough Banana Nut Muffins
- Store at room temperature, covered for up to four days.
- Freeze individual muffins on a sheet pan then, once frozen, store in a covered container for up to two weeks. Thaw at room temperature.
How to Rewarm Sourdough Muffins
Warm muffins in a 350F oven for about 10 minutes. They’ll be soft and tender. Slather them with butter, or as my mom would say, cream cheese.
- Muffin Liners: Use tulip muffin liners to support these fluffy sourdough banana nut muffins. They can be purchased (look for 2″ x 2 3/4″) or The Kitchn has a tutorial on how to DIY them!
- Oil Choice: I use coconut oil in this recipe. However, canola oil will also work.
- Flour Substitution? Choose all purpose or whole wheat white flour. Both make delicious muffins!
- Nut Options: Enjoy this recipe with walnuts or pecans. For nut-free muffins, they can be left out.
- Bananas: Make sure they’re soft, dark and/or heavily speckled. Mash them, then measure the portion.
- Kitchen Tools: I recommend a digital oven thermometer with an air probe and weighing your ingredients using a digital kitchen scale for the best outcome (affiliate links).
