Sourdough Discard Banana Bread (Date-Sweetened, No Refined Sugar)

Sourdough Discard Banana Bread (Date-Sweetened, No Refined Sugar)


What Makes This Banana Bread Different?

If you've been keeping a sourdough starter, you know the struggle of what to do with all that discard. This banana bread is the answer. It uses your sourdough discard to add a subtle tang and incredible depth of flavor — and instead of refined sugar, we sweeten it entirely with Medjool dates and ripe bananas. Fresh organic ingredients for banana bread

Key Ingredients & Why They Matter

Sourdough Discard

Don't throw it away! Sourdough discard adds a gentle tang, helps with leavening, and makes the crumb incredibly tender. Use it straight from the fridge.

Medjool Dates

Dates are nature's caramel. When blended smooth with the bananas, they create a deep, rich sweetness packed with fiber, potassium, and natural energy.

Greek Yogurt

My secret weapon for ultra-moist banana bread. Greek yogurt adds protein and keeps the crumb soft for days.

The Butter Tabs on Top

Do not skip this step! Dotting cold butter tabs across the top before baking creates the most beautiful golden crispy crust.

Batter in pan ready to bake

Tips for the Perfect Loaf

  • Use very ripe bananas — the spottier the better!
  • Blend your dates completely smooth before adding to the batter.
  • Want it sweeter? Add 2-3 extra Medjool dates to the banana-date mixture before blending for a naturally sweeter loaf.
  • Do not overmix — fold until just combined. A few lumps are totally fine!
  • Tent with foil after 40 minutes if the top is browning too quickly.
  • Let cool 15 minutes in the pan before slicing.


The Pan I Use

I bake this in my USA Pan Bakeware Pullman Loaf Pan 9x4 inch — made in the USA from aluminized steel with a nonstick coating. It gives the bread beautiful straight sides and bakes evenly every time. Highly recommend! (affiliate link)

Sourdough Discard Banana Bread (Date-Sweetened, No Refined Sugar)

Ingredients

  • 3 very ripe bananas, mashed

  • 8 Medjool dates, pitted

  • ½ cup sourdough discard

  • ⅓ cup coconut oil, melted

  • ¼ cup plain Greek yogurt

  • 2 eggs

  • 1 tsp pure vanilla extract

  • ¾ cup whole wheat flour

  • ¾ cup all purpose flour

  • 1 tsp baking soda

  • 1 tsp cinnamon

  • ½ tsp sea salt

  • 2 tbsp cold butter, cut into small tabs

Directions

  1. Preheat oven: Preheat your oven to 350°F. Grease your loaf pan well with coconut oil or line with parchment paper.
  2. Blend dates and bananas: In a blender or food processor, blend the dates and bananas until completely smooth with no chunks. This is your natural sweetener — make sure it's silky smooth!
  3. Mix wet ingredients: Pour the banana-date mixture into a large bowl. Add sourdough discard, coconut oil, Greek yogurt, eggs, and vanilla extract. Whisk until well combined.
  4. Mix dry ingredients: In a separate bowl, whisk together both flours, baking soda, cinnamon, and sea salt.
  5. Combine: Gently fold the dry ingredients into the wet until just combined — don't overmix! A few lumps are totally fine and keep the bread tender.
  6. Pour and top with butter: Pour batter into your prepared loaf pan. Scatter cold butter tabs evenly across the top — this creates a gorgeous golden crispy crust as it bakes!
  7. Bake: Bake for 60 minutes until a toothpick inserted in the center comes out clean. If the top is browning too fast, loosely tent with foil after 40 minutes.
  8. Cool: Let cool in the pan for 15 minutes before transferring to a wire rack. Slice and enjoy!
