Sourdough Chocolate Banana Bread

Please share

Make life a little sweeter with a loaf of sourdough chocolate banana bread. It’s a fun breakfast or a great simple treat.

This chocolaty bread is loaded with banana. It’s soft, moist, flavorful and perfect with a cup of coffee, tea or milk. Plus it is a great way to use some sourdough discard too!

Sourdough starter needs to be fed regularly to keep it bubbling away happily. In order to keep from having your starter take over your entire kitchen, you usually discard part of the starter and let the rest bubble away for another baking day.

The problem is, I don’t like discarding the discard. Poor Big Bertha (my sourdough starter) worked hard. So I like to show her the respect of baking every bit.

Nine times out of ten the discard finds its way into a sourdough pizza crust. This has kept pizza on a regular rotation on our dinner menu and I’ve heard no complaints about that!

I also have a big affinity for sourdough muffins. They are another great way to use some discard.

If you have a starter, you definitely need to put the muffins on your list.  Our favorites include the chocolate chip and caramel apple, but they are all good and pretty healthy as well!

I almost always have some bananas in the freezer. Lately they have mostly found themselves in smoothies, but as the weather turns colder they are likely to end up in a lot more baked goods.

So this bread is the culmination of the start of banana baking season and a hungry sourdough starter. The cross section of two forms of not wanting to waste any food turned into something delicious!

This bread is quick and easy to make. The addition of baking soda means you don’t have to wait for your starter to get going. It gets the boost it needs and keeps the banana bread texture we all know and love.

The chocolate of course makes it even better. I mean, it is chocolate after all.  The cocoa powder gives a nice chocolate flavor throughout and the chocolate chips kick it to the next level of goodness.

This bread is moist and flavorful on its own and is also great with a bit of butter smeared over top.

Do you have a sourdough starter? What are your favorite ways to use the discard?

The discard is another reason why I need to get some starter going! Your sourdough recipes all sound so good!

It is kind of a fun challenge to keep up with it without wasting any =)

Hi Carlee, I hate throwing any sourdough starter away, but sometimes just have to. I do keep two jars in the fridge, one with the fed starter and one with discard and am always on the lookout for anything to use up the discard. I'm going to have to give this recipe a try for sure!

I never discard starter. Pancakes/crepes and dumplings are good ways to use excess starter.

I have pizza on the menu tomorrow because my starter is looking hungry. THat is my go-to but muffins and quick breads are fun as well!
