Happy baking!

One of my favorite sayings it “use it up, wear it out, make it do, or do without.” Not that I am able to live by it, but I love the sentiment and I think it’s a worthy goal. And that is one of the frustrating parts of keeping a sourdough starter… you have to discard some of it every day! So any recipe that can use up that discard starter is always welcomed.

And of course, we all have a few overripe bananas in the house. Or is it just me? Anyway, this recipe uses up all those things in the kitchen that were not destined for greatness.

By the way, I know the word “sourdough” can be off-putting when we talk about sweet baked goods. But this recipe tastes just like the sweet, moist, classic banana bread we all know and love.

Step by step sourdough banana bread:

You can use either a stand mixer or hand mixer for this, whichever is easier for you.

It is a quick and easy recipe, so go ahead and preheat the oven to 350 degrees before you get started.

Beat the butter and sugar in a large mixing bowl until fluffy and well combined. It should look light yellow.

Then add the egg and the vanilla extract

Then the mashed banana and discard sourdough starter.

In a separate medium bowl, combine the flour, salt, baking soda, and baking powder.

Gently add the flour mixture to the wet ingredients, stirring until just combined.

Pour into a greased loaf pan, smooth out the top with a spatula, and bake for one hour. The top usually splits. A toothpick inserted should come out clean or with just a few moist crumbs. (Here are good guidelines on how to tell when quick bread is done.)

Cool completely before slicing.
