Sourdough Banana Muffins

  • Why have plain toast or English muffins when these muffins can be made in minutes?
  • A basket of muffins makes a perfect hostess gift or contribution to a potluck. Mini, regular, or jumbo-sized banana sourdough baked muffins are a sweet gift! Why not add a small jar of homemade Honey Butter?
  • Sourdough starter has a boost of prebiotic nutrition in it that is less likely to raise blood sugar levels—plus it makes muffins taste delicious!
  • If sourdough starter discard needs to be fed, just scoop some out and make a quick batch of muffins before feeding it.
  • The simple ingredients are probably already in the pantry and leave lots of room for alterations!

Ingredients and Variations

THE DRY MIXTURE: Flour, baking powder, and spices create the muffin base. For a heartier & healthier muffin, use half white and half whole wheat flour, and for a gluten-free option, switch out all the flour for your favorite gluten-free brand. (Unless the starter is made gluten free, the bread won’t be either, though, so be careful!)

THE WET MIXTURE: Use eggs, sourdough starter, bananas, oil, sugar, and vanilla. For lower carbs and calories, a sugar substitute can be used.

THE MIX-INS: Into the wet mixture, blueberry, applesauce, or pumpkin puree can be added. Chocolate, peanut butter, or toffee chips give the muffins extra sweetness, and walnuts, pecans, or even pumpkin seeds give a little crunch. Add some blueberries or strawberries for an extra fruity muffin.

How to Make Sourdough Muffins

You can still eat sourdough, even without the longer process of making a sourdough loaf:

  1. Whisk together dry ingredients in a bowl.
  2. Mix wet ingredients with an electric mixture until batter is smooth.
  3. Add wet ingredients to the dry, folding over & scraping the bowl. Avoid overmixing so the muffins stay aerated. Optional: this is where extra mix-ins can be gently folded in.
  4. Bake muffins (per recipe below) in prepared tins until a toothpick comes out clean. Let them cool on a wire rack.

Best Banana Muffin Tips

  • Set the yeast starter and eggs out about 20 minutes before using. Using them at room temperature helps them mix up extra fluffy.
  • If using berries of any kind (fresh or frozen), toss them in flour before adding in step 4, to keep them from sinking to the bottom of the muffins while they’re baking.
  • Toast nuts before using in any recipe by lightly sautéing them in a small pan until they are barely fragrant. This cooks off the natural oils to intensify their flavor and make them extra crunchy.

Storing Muffins

Making muffins every morning? Keep the batter in an airtight container overnight in the refrigerator, and scoop out enough for muffins as needed. Store baked muffins at room temperature in zippered bags with a slice of bread in it to absorb excess moisture. Freeze cooled muffins individually wrapped in plastic and placed in small, zippered bags. Thaw on the countertop overnight or pop a frozen muffin in a backpack or briefcase for a delicious mid-morning pick-me-up!

  • Preheat oven to 400°F. Line muffin tin with liners (or grease & flour).
  • In a large bowl, whisk together flour, baking powder, cinnamon, salt, and nutmeg.
  • In a medium to large bowl, whisk eggs until mixed. Add in sourdough starter, bananas, oil, sugars, and vanilla. Whisk until well combined.
  • Add wet mixture to the flour mixture and fold, scraping bottom and sides using a rubber spatula, until just mixed. Do not overmix or banana bread will be tough.
  • Divide batter evenly between muffin tins. Place into the oven & bake 17-19 minutes, until a toothpick comes out clean. Cool for 15 minutes, then transfer to a rack and cool completely.


Will keep 3-4 days in an airtight container, or in freezer for 4 months.
