Tips to Make Sourdough Banana Nut Bread

  • Use overly ripe bananas for that sweetness—brown is beautiful here!
  • If you have extra sourdough starter, feel free to play around with the proportions. More sourdough gives a bit more tang!
  • Don’t skip the toasting on those walnuts. It enhances the flavor beautifully!
  • Cut your bread only when it’s completely cool to prevent it from getting mushy.
  • Swap in chocolate chips for a fun twist, if you’re feeling indulgent.

Variation

Want to change things up? Here are a few easy ideas:

  • Replace walnuts with pecans or even almonds for a different nutty flavor.
  • You can sneak in some cocoa powder for a rich chocolatey banana bread.
  • For a healthier twist, use whole wheat flour or make it vegan by substituting the eggs with a flax egg or applesauce!
