Why We Love It

With two young daughters, we make a lot of healthy, simple loaves and muffins that are both nutritious and delicious. This sourdough banana nut bread recipe uses two types of whole grain flours, spelt and whole wheat, to increase the fibre and health benefits, but the recipe lends itself well to substitutions. We also use Greek yogurt (cottage cheese works well too if you blend it first!) for additional protein. Overripe bananas are perfect for adding natural sweetness and moistness to the bread, and the flavour is comforting and familiar, making it appealing to a wide range of palates. Here are a few more reasons why we love this recipe:

  1. Versatility:
    • Banana bread is incredibly versatile, allowing for various additions and flavor combinations. You can add nuts, chocolate chips, spices, fruit, or other ingredients to create unique variations.
  2. Easy to Prepare:
    • Banana bread is relatively simple to make, even for beginner bakers. It typically requires basic ingredients that are readily available in most kitchens.
  3. Reducing Food Waste:
    • It’s an excellent way to use up overripe bananas and leftover sourdough discard. We tend to freeze bananas that are quite brown so that we can defrost and make banana bread whenever we want.
  4. Comfort Food:
    • The aroma of banana bread baking in the oven is incredibly comforting. It is a staple for us when we want a quick treat that everyone loves.
  5. Made with Whole Grains:
    • This recipe uses only whole grain spelt and whole wheat flour. Not only is this healthier for the family, it is also full of whole grain flavour.

The Mixing Process for Sourdough Banana Nut Bread

The mixing is pretty straightforward forward but be careful not to overmix the batter.

  • Start by combining all the dry ingredients in a bowl and use a whisk to fully incorporate them.
  • Mix the wet ingredients in a seperate bowl then add that to the dry. Mix this until ALMOST combined and then add the walnuts and fold them in with a spatula.

Baking Banana Nut Bread

For garnish, you can slice a banana in half and place it on the top with the sliced side up. If you are making a batch to freeze, we suggest leaving the banana off the top of the loaf. Your loaf will stay fresh for 2-4 days in an airtight container at room temperature, or 2-3 weeks in the freezer.

Sourdough Banana Nut Bread Variations

This sourdough banana nut bread is a super versatile recipe, and there are many ways to change up the flavour variations as a twist to the classic version. Here are a few variations that we recommend:

  1. Chocolate Chip Banana Bread:
    • Substitute the walnuts for chocolate chips. You can also sub half the walnuts for chocolate chips so you get the best of both worlds. We love using dark or semi-sweet chocolate, but you can use whatever type of chocolate you prefer. If you don’t have chips, you can chop up a bar of chocolate for some delicious chocolate chunks.
  2. Coconut Banana Bread:
    • Substitute the walnuts for shredded coconut for a nice tropical flavour. You can also sprinkle some on top before baking for added texture.
  3. Blueberry Banana Bread:
    • Gently fold fresh or frozen blueberries into the batter in place of the walnuts for a burst of sweetness and a pop of colour.
  4. Peanut Butter Banana Bread:
    • Omit the walnuts and swirl in 3/4 cup of peanut butter into the batter. For extra decadence, add in 3/4 cup of chocolate chips.
  5. Cinnamon Swirl Banana Nut Bread:
    • Omit the walnuts or leave them in, whatever you prefer. Add 2 tsp cinnamon to the dry ingredients before mixing the batter. In a separate bowl, mix 1/4 cup sugar with 1 tbsp cinnamon. Sprinkle the mixture on top of the banana bread before it goes into the oven for a wonderful crunchy topping.

  • Absolutely perfect recipe. (And I’ve made many a fine banana bread). I used WW pastry flour which made it fine and custardy, like the Cape Malva pud I love. I left the walnuts out to preserve that texture but last minute, tucked some halves just under the top around the banana. Topped with a brown sugar-cinnamon shower. Perfect. Thanks so much for sharing this and all that you share !
