Chocolate Sourdough Banana Muffins

Banana bread is a classic, tried and loved recipe to use your extra overripe bananas. I love banana bread (especially my sourdough discard banana bread) but sometimes, it’s nice to mix it up a little bit. My chocolate sourdough banana muffins are a decadent variation of banana bread that is perfect for any chocolate lover.

Why You Will Love these Chocolate Sourdough Muffins

These muffins were inspired by and adapted from my vegan chocolate banana muffins, which is a favorite recipe in my family. Although I wrote this recipe to include an egg, I have made them multiple times with a vegan egg substitute. This makes them a great recipe for any vegans, or anyone who is egg-free or dairy-free.

You will also love how easy it is to grab one of these muffins when you are on the go. I prefer muffins for this reason. If you prefer classic banana bread, check out my sourdough discard banana bread muffins which have a delicious streusel topping. 

How to Use Sourdough Starter in Chocolate Banana Bread Muffins

I recommend using a starter that is fed with equal parts flour and water by weight. This is commonly referred to as 100% hydration.

You can also use active starter or sourdough starter discard straight from the fridge. 

Ingredients and Substitutions

  • Flour: You can use all purpose flour or bread flour in this recipe. You can also substitute a small amount of whole wheat flour for some of the white flour if desired by I wouldn’t use more than 1/3 cup or your muffins may turn out dry. 
  • Cocoa Powder: I recommend dutch-processed cocoa powder as it has a richer flavor than natural cocoa but you can use natural cocoa if desired. 
  • Baking Powder
  • Baking Soda
  • Salt
  • Bananas: You want very overripe bananas. I recommend almost completely black but you can use bananas that are heavily spotted brown as well. 
  • Sourdough Starter: Use active starter or sourdough discard. See notes above.
  • Oil: Any neutral flavored oil will work. I prefer avocado oil but canola oil or vegetable oil will work well too.
  • Sugar
  • Brown Sugar: You can use light or dark brown sugar. 
  • Egg: The egg is the only ingredient that makes these not vegan. If vegan, substitute with your favorite egg substitute. 
  • Vanilla Extract: I recommend pure vanilla extract rather than imitation vanilla but you can substitute this if desired. 
  • Chocolate Chips: I recommend dark chocolate or semi-sweet chocolate chips but you can also substitute peanut butter chips or nuts of your choice.

How to Store

Store these muffins in an airtight container, gallon storage ziplock bag, or on a plate wrapped with plastic wrap. I recommend storing these in the refrigerator and they are best when consumed within 5 days. 

You can also freeze these in a freezer safe bag. I recommend using within 3 months for best results.
