Ingredients
Scale
8 Tbsp butter (113g), room temp or slightly softened (not melted)
1 cup coconut sugar (170g)
1 1/2 tsp pure vanilla extract
1 1/2 tsp ground cinnamon
1 tsp salt
1 tsp baking soda
1 tsp baking powder
400g mashed very ripe banana
90g (1/4 cup) honey or pure maple syrup
2 large eggs
115 g (1/2 cup) sourdough starter (discard is fine)
280g heritage flour or white flour (2 1/4 properly spooned and leveled)
Optional additions: chocolate chips, chopped nuts
Instructions
- Preheat the oven to 325°F. Lightly grease a 9″ x 5″ loaf pan (I used glass).
- In a large bowl, combine the butter, coconut sugar, vanilla, cinnamon, baking soda, baking powder, and salt, beating until smooth. This works best with a kitchen-aid mixer. You can use a hand mixer as well, but I recommend a large and tall bowl to prevent the mixture from flying out of the bowl while you are mixing it.
- Add the mashed bananas, honey, eggs, and sourdough starter. Beat until combined.
- Add the flour and stir just until smooth. Do not over-mix.
- Transfer the batter to the prepared loaf pan, smoothing the top. Let it rest at room temperature for 10 minutes.
- Bake for 45 minutes, then gently lay a piece of parchment paper across the top to prevent over-browning.
- Bake for an additional 20-25 minutes. Remove the bread from the oven; a long toothpick inserted into the center should come out clean, with a few wet crumbs clinging to it. The tester shouldn’t show any sign of uncooked batter. If it does, bake the bread an additional 5 minutes, or until it tests done.
- Allow the bread to cool for 10-15 minutes in the pan. Then remove it from the pan to cool completely on a rack.

Notes
Store leftover bread, tightly wrapped, at room temperature for several days.
Freeze for longer storage. Tightly wrap it then place in a freezer-friendly container. Freeze for up to 3 months. You can also freeze individual slices the same way.
How to omit the sourdough starter if you don’t have it:
The sourdough starter can easily be replaced with equal parts milk and flour. For example, the recipe calls for 115 g of sourdough starter, so if you want to replace it, then use 58 g of milk and 58 g of flour in its place (I rounded up for ease). Keep in mind, this 58 g of flour is in addition to the flour already called for in the recipe.
