Sourdough Banana Bread Ingredients:

• 1/4 cup maple syrup
• 2 cups all purpose einkorn flour (or regular all purpose flour)
• 1/2 cup melted butter
• 1/4 cup kefir (or buttermilk)
• 2 eggs
• 1 tsp vanilla extract
• 1 tsp baking powder
• 1 tsp baking soda
• 1/2 tsp sea salt
• 1 cup chocolate chips (optional)
• 1/2 cup chopped walnuts (optional)

Sourdough Banana Bread Instructions:

Step 1: Prepare Batter

Add mashed bananas, sourdough starter, maple syrup, and flour in a large bowl. Stir until well combined. You might want to knead for a minute with your hands to bring it together.

Step 2: Ferment Sourdough Loaf

Cover bowl and leave to ferment for 4-6 hours at room temperature or 10-16 hours in the fridge. Make sure the seal is airtight (use cling wrap, beeswax wrap or a fitted bowl cover).

Step 3: Stir in remaining Banana Bread ingredients

Stir in remaining ingredients, then pour into a loaf pan, greased or lined with parchment paper.

Optional: Add 1 sliced banana on top for decoration!

Step 4: Bake Sourdough Banana Bread

Bake at 350 F for 60 minutes, until toothpick comes out clean. Check after 30 minutes, and cover with tinfoil if the top is starting to burn.

Step 5:

Let cool in the loaf pan for 1 hour before gently removing. Slice and enjoy!

Storage:

This loaf will keep well in an airtight container in the fridge for up to 5 days. You can also freeze in airtight container for 1 month. Take out the night before to defrost.
