How to Make the Recipe
Now, let’s get baking! Follow these simple steps to create your own Sourdough Banana Bread:
- Preheat the oven to 350 degrees F and grease and line a 9 x 5 inch loaf pan with parchment paper for easy removal. Set aside.
- In a bowl of a stand mixer with a paddle attachment, cream room-temperature butter and sugar on medium speed until light and fluffy, about 2-3 minutes. This can also be done with a hand mixer.
- Once combined, add the eggs to the mixture, one at a time, continuing to beat on medium speed until it is light, fluffy, and pale yellow in color. Stop to scrape the sides of the bowl when necessary.
- In a separate bowl, whisk together the flour, baking soda, and salt until combined. Set aside.
- While mixing on stir/low, alternate adding the dry ingredients and sourdough discard to the egg mixture. Occasionally stop mixing to scrape the sides of the bowl. Mix until there are just a few streaks of flour left.
- Lastly, add the mashed bananas and vanilla extract to the batter. Mix on low until just combined. If adding mix-ins like walnuts or chocolate chips, gently fold them in using a rubber spatula.
- Add the batter to the prepared loaf pan. Sprinkle with additional chopped nuts or chocolate chips on top, if desired. Bake for 55-65 minutes or until a toothpick comes out clean or with a few moist crumbs.
- Remove from the oven and cool in the pan for 30 minutes before transferring to a wire rack to cool completely. For easiest slicing, wait at least an hour before cutting.
Pro Tips for Making the Recipe
Here are some helpful suggestions to ensure your Sourdough Banana Bread turns out perfectly:
- Make sure your bananas are very ripe for the best flavor and sweetness.
- Don’t overmix the batter; it’s okay if there are a few flour streaks left.
- Feel free to experiment with different add-ins like chocolate chips or dried fruit for a unique twist!
- If you want to make this a healthier option, consider substituting half of the sugar with honey or maple syrup.
How to Serve
This Sourdough Banana Bread is delicious on its own, but here are some serving suggestions to elevate your experience:
