Mastering Vegan Sourdough Banana Bread: How-To

Get ready to create your new favorite bread with these simple steps:
Step 1: Prepare the Flax Egg
In a small bowl, mix the ground flax seed with water. Let it sit for about 5-10 minutes until it thickens. This will act as your egg substitute.
Step 2: Mash the Bananas
In a large mixing bowl, mash the ripe bananas until smooth. The riper the bananas, the sweeter your bread will be!
Step 3: Combine Wet Ingredients
Add the prepared flax egg, sourdough starter, avocado oil (or melted coconut oil), and vanilla extract to the mashed bananas. Mix until everything is well combined.
Step 4: Mix Dry Ingredients
In a separate bowl, whisk together the gluten-free flour, baking soda, sea salt, and ground cinnamon.
Step 5: Combine Wet and Dry Ingredients
Gradually add the dry mixture to the wet ingredients, stirring gently until just combined. Be careful not to overmix—this will keep your bread light and fluffy.
Step 6: Fold in the Walnuts
Gently fold in the chopped walnuts, ensuring they are evenly distributed throughout the batter.
Step 7: Transfer to Loaf Pan
Pour the batter into the prepared loaf pan, smoothing the top with a spatula.
Step 8: Bake
Preheat your oven to 350°F (175°C) and bake the banana bread for 50-60 minutes or until a toothpick inserted into the center comes out clean.
Step 9: Cool
Once baked, allow the bread to cool in the pan for about 10 minutes before transferring it to a wire rack to cool completely.
