This grain-free sourdough banana bread is as easy to make as it is delicious to eat! It is full of ripe bananas and lightly sweetened further by a touch of honey. This banana bread is primarily made with almond flour making it healthier than your average banana bread. It is also completely grain-free, gluten-free, and dairy-free! The grain-free sourdough starter adds to the complexity of flavor and increases its digestibility. It is also Paleo friendly!

How to Make this Grain-Free Sourdough Banana Bread
Step One – Preheat your oven to 350 degrees F and line an 8.5 inch loaf pan with parchment paper.
Step Two – Weigh your dry ingredients in a medium bowl, then whisk to combine and set aside.
Step Three – weigh your bananas in a small bowl and then mash with a fork.

Step Four – To a large mixing bowl add the sourdough starter, eggs, vanilla extract, and avocado oil. Whisk well to combine and then add the mashed bananas. Stir to combine with a rubber spatula.
