Banana bread is something that is wonderful to have on hand to add to a breakfast spread or as a quick snacks for littles. It is a classic quick bread and is super soft, fluffy, and moist.
I absolutely love making this in the summer! The windows open, birds singing, bare feet in the kitchen, and the smell of banana bread baking is a combination that is too good to miss!
Bananas are naturally very sweet, especially so if left to ripen well till covered in brown spots. The addition on cinnamon, nutmeg, and ginger add the perfect amount of warmth and spice. This bread is perfectly sweet with the option to substitute the sugar for coconut sugar, rapadura, or sucanat if you prefer.
This is a great way to use up extra sourdough discard! It adds a wonderful flavor that isn’t sour at all. Anything is better with the addition of sourdough in my opinion! I love to know that I am feeding my family well in a way that tastes good too!
Tips:
- In this recipe you can use fed and active starter or sourdough discard that has deflated and maybe even looks a little sad. Either one will work great!
- You can make this quickly or you can let it long ferment for as long as you would like, to get the most nutrients out of your grains.
- If you don’t have brown sugar, make your own! Add 1 tsp. of molasses to the sugar and combine with a fork until well blended.
- Use all-purpose flour, freshly milled whole grain, or a combination of both!
- Want some variety? Add chocolate chips, nuts, or dried fruit to add texture and sweet or nutty flavor!
- Make into muffins instead of bread! Perfect for no-think grab and go snacks.
- Mash bananas until smooth or leave some chunks for a more textured bread with delicious sweet banana pieces.
- Make sure not to overmix! It will result in a bread that is tough.

Ingredients for sourdough discard banana bread:
- Sugar (3/4 cup)– Brown sugar prefered. I use organic cane sugar or coconut sugar. You can also use rapadura or sucanat.
- Molasses (1 tsp. – OPTIONAL!) – If using cane sugar, add 1 tsp. of molasses to the sugar and combine with a fork till well incorporated.
- Coconut oil or butter (1/2 cup) – Softened to room temperature. Either butter or coconut oil works great! Use coconut oil if you prefer a dairy free bread.
- Bananas (3 large ones – approx. 1 cup) – Well ripened and covered with brown spots is best!
- Eggs (2 large) – Helps to make the bread fluffy and binds the ingredients together.
- Sourdough starter (1/2 cup) – active or discard
- Flour (2 cups – if using all freshly milled whole grain add 1/4 cup more) – Organic all-purpose, freshly milled whole grain, or a mixture of both!
- Baking soda (1 tsp.)
- Salt (1/2 tsp.) – I use sea salt or pink himalayan salt
- Nutmeg (1/2 tsp.)
- Cinnamon (1/2 tsp.)
- Ginger (1/4 tsp.)
Optional add-ins:
Add up to 1 cup of any, or a combination, of these:

Instructions

4. Add the dry ingredients to the wet ingredients and stir gently just until combined. Don't stir too much or else your bread will be tough.

We love banana bread, but I’ve never made it with discard. I’m excited to try this recipe and have another way to use up discard! Thank you for sharing the recipe!
Ooo I love how this is a much healthier version of banana bread! I’d love to try it with the molasses as I’ve never done that before. Thank you for this recipe!
This looks good! I use my sourdough every day. It’s nice to find new recipes that I can add to my agenda!
Peace, Kirsten
