Ingredients

  • 2 & ¼ Cup All Purpose Flour Scooped and leveled.
  • 1 teaspoon Baking Soda
  • 1 teaspoon Salt
  • 1 teaspoon Cinnamon
  • 1 Stick (½ Cup) Unsalted Butter Softened
  • ¾ Cup Granulated Sugar
  • ¼ Cup Full Fat Yogurt
  • 1 Cup Sourdough Starter Discard 12-24 hours after feeding
  • 2 teaspoons Vanilla Extract
  • 2 Large Eggs
  • 4 Large Very ripe, soft bananas Will equal about 2 cups of mashed bananas.

Instructions

  • Preheat oven to 350 degrees Fahrenheit.
  • Prepare a loaf pan by spraying with non-stick spray or a coating of butter with a dusting of flour. Whichever way you prefer to prepare baking pans. Set aside.
  • In a small bowl, mix together the flour, salt, baking soda, and cinnamon. Set aside.
  • In a large glass bowl, mix together the butter and sugar with a hand mixer until it's fully combined and has a soft, fluffy texture.
  • Next, add in the yogurt, sourdough starter and vanilla extract. Mix well with a hand mixer until everything is fully combined.
  • Add in eggs and mix again with the hand mixer just until they are fully incorporated. Don't overmix.
  • In a medium bowl mash bananas with a fork until they are a creamy consistency. Some smaller lumps are okay. The softer the bananas are the easier they will be to mash.
  • With a wooden spoon or spatula, fold in the mashed bananas just until everything is fully incorporated.
  • Dump in the flour mixture, and with a wooden spoon, fold everything together until the flour is fully incorporated. Use a spoon or spatula at this point because we don't want to overmix the batter. That can lead to a dense texture.
  • Pour the batter into the prepared loaf pan and using a spoon or spatula scrape the bottom of the bowl so all the batter makes it in the pan.
  • Give the pan a good shake so the batter settles and is evenly distributed.
  • Place pan in the oven and bake for 55-60 minutes.
  • About halfway through if the top of the bread starts to turn brown, make a tent out of tin foil and place it over the top. This will allow the inside of the bread to continue to cook but will protect the top from burning.
  • The bread is done when a toothpick is inserted in the middle and comes out clean.
  • When done, place the pan on a cooling rack and allow the bread to cool inside the pan for 10 minutes.
  • Take a knife and run it between the bread and the side of the pan. Just to get any piece that may be stuck.
  • Remove loaf from the pan and allow it to cool.
  • Slice and serve with a little butter and enjoy!

Notes

Ingredient Notes:
  • When measuring the flour make sure to scoop flour out with a spoon into the measuring cup and level with a knife.
  • This recipe calls for about 2 cups of mashed bananas. That will be about 4 larger size bananas. The softer the banana the better. If they are too firm it will be difficult to mash.
  • Make sure butter is soft and at room temperature. The butter and sugar need to be creamed together. Softer butter will allow it to come to a creamy consistency. You shouldn't see any lumps of butter.
 
Top Tips
  • Use overly ripe banana: Make sure the banana are turning brown and ripe. This will make the bread softer and the bananas easier to mash.
  • Cream the butter and sugar: Make sure these two ingredients are completely combined before moving on. It should be soft, creamy and zero butter lumps. Do not move on until this is accomplished.
  • Don't overmix: Once the eggs are added just mix the batter until the ingredients are combined. Overtaxing will lead to very dense bread.
  • Make Tin Foil Tent: If the top of the loaf starts to get too dark make a little tent out of tin foil and lightly cover the bread. This will keep the top from browning but the center still cooks.
