A super easy sourdough recipe - great for beginners!
Preheat oven to 350°F. Butter and flour an 8.5x4.5-inch loaf pan, tapping out the excess flour.
In a small bowl, whisk together the flour, baking soda, salt, and cinnamon. Set aside.
In a large bowl, cream the butter and sugar together until light. Add the bananas and beat until the bananas are well "mashed." Add the eggs and vanilla and beat until well combined. Add the sourdough starter and mix just until incorporated.
Add the dry ingredients and gently mix on low speed just until combined. Add the chocolate chips and gently fold them in with a spatula.
Scrape the batter into the prepared loaf pan. Bake in preheated oven for 60-70 minutes, or until a toothpick inserted near the center comes out clean.
Allow the loaf to cool in the pan on a rack for 10 minutes before inverting on the rack to cool completely (or at least until just warm). Serve with grass-fed butter.
