This moist banana quick bread is a great way to use up your brown bananas and leftover starter. It's delicious plain, or with the addition of chocolate chips and nuts!

Ingredients
  

  • ½ cup salted butter, softened to room temperature
  • 1 cup white sugar
  • ½ cup sourdough starter discard
  • 1 ½ cups mashed overripe bananas (3 large or 4 small bananas)
  • 1 tsp vanilla extract
  • 2 large eggs
  • 2 cups all purpose flour (10 ounces)
  • ½ tsp salt
  • 1 tsp baking soda
  • ½ tsp baking powder

Instructions
 

  • Spray two 8.5 x 4.5 inch loaf pans with cooking spray and line the bottom with parchment paper. Mash the bananas with a fork. Preheat your oven to 350°.
  • In a large mixing bowl, beat the butter and sugar with an electric hand mixer for 2-3 minutes, occasionally scraping the sides of the bowl with a rubber spatula. The mixture should be creamy and pale.
  • Add the discard, mashed banana, vanilla, and eggs; beat until smooth.
  • In a separate bowl, whisk together the flour, salt, baking soda, baking powder, and salt. Add to the banana mixture with any mix-ins. Stir gently just until there are no streaks of flour.
  • Divide the batter evenly between the prepared loaf pans. Bake in a preheated oven at 350° for about 40-45 minutes, or until a toothpick inserted in the center comes out with just a few moist crumbs, no wet batter.
  • Let the bread cool in the pan for about 10 minutes, then carefully remove the loaves and place them on a wire rack.
  • You can serve the bread warm, but for the cleanest slices, let it cool completely.

Notes

  • Mix-ins make this flavorful banana bread even more delicious! I like to make one loaf with 1/3 cup of pecans, and one loaf with 1/3 cup of chocolate chips. Just keep in mind that adding additional ingredients will increase the baking time by a few minutes. 
  • Bread can be wrapped in plastic wrap or stored in an airtight container for 3-4 days. For longer storage, wrap it, then place it in a freezer bag. It will last for 4-5 months.
  • You can make this bread in one 9x5" loaf pan, but you will need to increase the baking time to 55-65 minutes. Don't add any mix-ins, or it can overflow. 
  • For muffins, fill 18-20 greased muffin cups; bake for about 20 minutes. Mini muffins only take 14 minutes.
