Let’s Talk About Sourdough for a Minute
The sourdough in this recipe contributes to overall flavor without screaming: I AM SOURDOUGH, HEAR ME ROAR. In fact, if you ate a piece of this bread without knowing any details, I’m almost positive you wouldn’t peg it as a sourdough recipe at all.
However, where the sourdough absolutely shines is in the lusciously soft texture that is unlike any other banana bread I’ve ever had.
You guys, this bread is so incredibly delicious.

Banana Bread Batter
This one-bowl banana bread batter is very straightforward.
Mix the wet ingredients:
- neutral-flavored oil
- brown sugar + granulated sugar
- mashed bananas
- sourdough starter (fed or discard)
- eggs
- vanilla
And then stir in the dry ingredients:
- flour (all-purpose or whole wheat)
- baking powder + baking soda + salt
- ground cinnamon


A Substantial Loaf
This recipe makes one large loaf of banana bread. Which means!! —> Don’t try shoving the batter into a smaller loaf pan. You’ll be sad and so will your oven when things go awry and start over flowing into bubbling, burning carnage.
*Use a 9X5-inch loaf pan*
If you only have smaller loaf pans (like an 8 1/2 X 4 1/2-inch size), fill the pan slightly more than 2/3 full and use the rest of the batter for mini loaves or a few muffins.
I have made this bread at least a dozen times and while the loaf pan is full, it has never overflowed (I live at about 2,500 feet elevation). It domes up beautifully while baking.

A Tried-and-True Banana Bread Recipe
I am so excited for you to try this recipe.
If you don’t have a sourdough starter, beg, steal or borrow until you do! I promise this bread is worth it.
I’ve added *a few* chocolate chips with good results. Baked in mini loaf pans with good results. Doubled and tripled the recipe with good results. Delegated the making of to the children with good results.
It’s just one of those amazing and soul-fulfilling recipes I can’t envision my life without. Long live sourdough banana bread. 💗
