Sourdough Banana Bread with Sprouted Rye and Maple Syrup

I let my sourdough banana bread ferment and rise for hours. This is the best sourdough banana bread recipe, so flavorful and easy to digest!

Sourdough Banana Bread

While many banana bread recipes are more like cake, my sourdough banana bread is more like soft sweet bread.

For this recipe, you want to use brown sugar and maple syrup for the best flavor. The pure vanilla extract with maple syrup, brown sugar, and rye flour creates a fabulous caramel flavor.

I like to whip softened grass-fed butter with organic maple syrup to spread on a slice for a perfect sweet snack.

My Sourdough Banana Bread Recipe

Here are all the ingredients and supplies you need to make this fermented sourdough banana bread:

  • salt
  • chia seeds
  • baking Soda
  • all-purpose flour
  • rye flour (I used sprouted rye flour, but any rye flour will do)
  • Cinnamon
  • brown sugar
  • Sourdough Starter
  • warm water or milk
  • ripe banana
  • coconut oil
  • maple syrup 
  • vanilla extract

You will also need:

  • 9×5 loaf pan
  • parchment paper

Making Banana Bread with Sourdough Starter

Most sourdough banana bread and zucchini bread recipes don’t allow any rise time. Instead, most people treat it like a sourdough discard recipe that goes straight into the oven after combining the ingredients.

I let my sourdough banana bread rise. Allowing the dough to ferment and rise has two main benefits.

First, the flavors and textures develop so nicely. Second, giving the dough time to ferment and rise makes the bread easier to digest. I have trouble digesting fructans, which bananas and rye flour contain a lot of.

When sourdough ferments, the starters’ microbes pre-digest all the fructans in the banana and flour, so it gives me no trouble. You can learn more about the digestibility of sourdough by clicking here.

Sourdough Banana Bread with Sprouted Rye and Maple Syrup

I let my sourdough banana bread ferment and rise for hours. This is the best sourdough banana bread recipe, so flavorful and easy to digest!

  • Prep: 30 Minutes
  • Cook: 1 Hour
  • Total Time: 5 hours 30 minutes

Ingredients

  • 2 Tablespoons Chia Seeds (optional)
  • 1 Teaspoon Salt
  • 1 Teaspoon Baking Soda
  • 1 3/4 Cup All Purpose Flour
  • 1 Cup Rye Flour
  • 1 Teaspoon Cinnamon
  • 2 Tablespoons brown sugar
  • 1 Cup Sourdough Starter, active and bubbly
  • 1/2 Cup warm water or milk
  • 1 Teaspoon Vanilla extract
  • 1 Mashed Ripe Banana
  • 1/4 Cup Coconut Oil, Melted
  • 3/4 Cup Maple Syrup 

Instructions

  1. Line a 5″ by 9″ loaf pan on all sides with parchment paper. 
  2. In a mixing bowl, combine the chia seeds, salt, baking soda, flour, cinnamon, and brown sugar. Mix until evenly combined. 
  3. In a separate bowl, combine the sourdough starter, warm milk, vanilla extract, ripe banana, coconut oil, and maple syrup. Whisk until the mixture is uniform. (note that the sourdough starter is a wet ingredient)
  4. Pour the wet ingredients into the dry ingredients and fold in until evenly combined. The mixture will be wet and stretchy.
  5. Transfer the mixture to the parchment paper-lined loaf pan. Using a spatula, spread the mixture into the pan evenly. Top with banana slices. 
  6. Allow rising at a warm temperature for 4 hours. 
  7. Preheat oven to 350 degrees F.
  8. Bake for 1 hour, rotating the pan halfway through.
  9. Allow to cool for 30 minutes, then slice.  
  10. Store in an airtight container.

Notes

Optional Streusel Topping

  • 2 Tablespoons Cold Butter
  • 1 Tablespoon Flour
  • 2 Tablespoons Sugar

For the streusel topping (optional), combine the sugar, flour and butter. Sprinkle ontop of the loaf right before it goes in the oven.

    I am very excited to try this bread but wondered if you ever tried it with just the starter and no baking soda?

    Do you think you could leave the batter in the pan overnight for a long ferment ?

      I’ve never tried it overnight, but it should work. It would probably be best to do the overnight ferment in the fridge.

    I baked this today and this is absolutely amazing yummy tasty banana bread!
    A few changes I made: I decreased the amount of maple syrup to 1/2 cup and added more banana (total 3 super ripe bananas) and for my taste could go lower in sweetness!
    I could not bake it yesterday, so I put it into the fridge over night. As it did not really grow in the fridge, I left it at room temperature for a couple of hours and baked it.
    Next time I might add walnuts!

    Do you think you could sub all whole wheat for both the AP and rye flour?

      You can try it, but using all whole wheat flour may result in a dense bread

Sourdough starter makes brownies a little more cake-like, so I had to up the fats in the recipe a bit to keep them moist and used a combo of brown butter and oil.

Fermented garlic honey, and I make mine as an oxym Fermented garlic honey, and I make mine as an oxymel 

🍯✨🫧🧄 the recipe is on my website!
https://cultured.guru

Many historical texts mention the use of both garlic and honey in traditional medicine. Still, none explicitly describe the modern method of combining only these two ingredients and leaving them to ferment. In all my readings on fermentation history, I’ve never come across any historical descriptions of fermented garlic honey, made with only garlic and honey.

However, I did come across many accounts of over 1,200 types of oxymel in Ancient Greece and Persia, many of which include garlic.The ancient Greeks and Persians used oxymels to extract and preserve potent herbs, including garlic. Oxymel is an ancient preparation, and Hippocrates wrote records about its benefits around 400 B.C.E. in On Regimen in Acute Diseases.

The thing to note here is that oxymel uses a combination of honey and raw vinegar.

When we make fermented garlic honey as an oxymel, the pH starts at a safe acidity and remains at a safe acidity (below 4.6). This is because the microbes in raw vinegar (or raw kombucha) ensure the honey is metabolized into more acids. These microbes “eat” sugars similarly to the way they do when making kombucha, wild mead, and vinegar. When we add raw vinegar or raw kombucha to a garlic honey oxymel, we are guaranteeing the presence of many acid-producing microbes that keep the mixture acidic and safe.

PSA: I’m not saying that your garlic honey made without raw vinegar is destined to have botulism. But I am saying without raw vinegar/kombucha it is a concern, and it can happen. I am saying that I’m not comfortable making it without raw vinegar/kombucha. 

I have compiled all my thoughts on garlic honey and botulism in the blog post, linked in my bio! You can also type “cultured.guru” right into your web browser and the recipe blog is on my homepage.

Oxymel is a medicinal herbal elixir, made through Oxymel is a medicinal herbal elixir, made through the fermentation of herbs in honey and raw vinegar. 

It’s my favorite time-tested herbal remedy that’s over 2,400 years old. It originated in ancient Greece and Persia, where it was considered a gift from the gods.

Hippocrates, the famous ancient Greek physician, was a staunch advocate of oxymel and incorporated it into his medical practices. Depending on the herbs used to make it, oxymel can help with many ailments and improve health in various ways!

In a world where everyone is asking AI, I set out to learn about the best herbal combinations from real, practiced experts in herbalism.

I felt so much joy collaborating with these herbalists @openspace.center @karlytheherbalist @lilianaruizhealy and @the.brettivy to recommend the best medicinal herb combinations in this recipe!
