Tips for the Best Banana Bread

This sourdough banana bread is super simple. However, there are a few tweaks you can make to an already incredible recipe, to ensure a perfectly flavorful loaf!

  • Make sure you’re using overripe bananas. These dark brown bananas will help sweeten the banana bread thanks to their incredibly squishy interior. If you happen to have a good bunch of overripe bananas, simply pop them into the freezer until you’re ready for your next banana treat!
  • Once you’ve added your wet ingredients to the dry ingredients, try not to overmix your batter as this can produce tough bread.
  • If you find that the tops of your loaves are browning too quickly, then cover your banana bread with a sheet of foil. This will enable the bread to continue cooking without burning the top of your loaf.

Optional Add-Ins

There’s no doubt that this sourdough banana bread is delicious as is. But, there are a couple of additional inclusions that can transform an already delicious banana bread into something phenomenal!

Here are some ideas for you to consider:

  • Roasted and chopped nuts: Lightly toast your choice of chopped nuts in a heated pan before adding them to the rest of your ingredients. You can add up to 150g of chopped walnuts, cashews, hazelnuts, pecans, or macadamia nuts.
  • Chocolate: Chocolate coupled with banana makes the perfect treat. Add up to 100g of chocolate chips or your favorite chocolate chopped.

By Natasha Krajnc

Hi! My name is Natasha and I'm specialized in home sourdough bread baking and currently based in Slovakia - a very small country in Central Europe. My bread baking story began in 2011 when I decided to give up commercial yeast. I felt tired all the time (especially after eating bread and other foods made with yeast), I wasn’t motivated to do anything, had trouble concentrating throughout the day, my abdomen was bloated and I was like a trumpet on steroids – basically, I was quite a wreck. I was a big bread lover (and still am) and having to stop eating bread was quite hard at that time but I felt I was on a right way to give my body a chance to heal itself.
