SUMMARIZE & SAVE THIS RECIPE ON

A good banana bread recipe is one of those staples every kitchen needs. It is what you make when the bananas turn brown on the counter and nobody is volunteering to eat them anymore. In our house, this sourdough discard banana bread has become that recipe because it is soft, reliable, filled with chocolate chips, and always disappears quickly.

If your family already loves my best sourdough discard chocolate chip cookies, this loaf has that same homemade chocolate chip flavor, with even more moisture from the ripe bananas and sourdough discard. My homemade sourdough Oreo cookies are another fun option when you have extra discard and want something a little more dessert-like.

Why You’ll Love This Sourdough Discard Banana Bread

Soft, moist, and full of banana flavor. Overripe bananas keep the crumb tender, while chocolate chips add pockets of melted chocolate throughout every slice.

An easy way to use sourdough discard. Instead of throwing away extra starter, you can turn it into a simple quick bread the whole family will actually eat.

Quick and uncomplicated. There is no kneading, shaping, or waiting for the dough to rise. Mix the batter, pour it into the pan, and bake. A suspiciously reasonable sourdough recipe.

Perfect for breakfast or snacks. Enjoy a slice with coffee in the morning, pack it for an afternoon snack, or serve it as an easy dessert.

Freezer friendly. The loaf stores well and freezes beautifully, so you can make it ahead and save individual slices for later.

Optional long fermentation. You can refrigerate the batter for several hours or overnight for a slightly deeper sourdough flavor. Some people also find long fermented baked goods easier to tolerate.

Plenty of chocolate chips. The chocolate adds just enough sweetness and richness to balance the bananas and subtle sourdough tang.

Key Ingredients

Ingredients for sourdough discard banana bread with ripe bananas, sourdough starter, flour, brown sugar, eggs, butter, and chocolate chips.

Sourdough discard: Active starter or unfed sourdough discard both work in this recipe. It adds moisture and a slight tang without making the bread taste strongly sour.

Overripe bananas: Use very ripe bananas with plenty of brown spots. The riper they are, the sweeter and more flavorful the banana bread will be.

All-purpose flour: Gives the loaf enough structure while keeping the crumb soft and tender. Measure it carefully to avoid dry, dense banana bread.

Unsalted butter: Adds richness and helps create a soft, flavorful crumb. Let it soften at room temperature so it creams smoothly with the sugar.

Brown sugar: Sweetens the loaf while adding moisture and a deeper caramel-like flavor. Coconut sugar can also be used, although the flavor and color may vary slightly.

Eggs: Bind the batter together and add structure, helping the bread bake into slices without becoming dry or crumbly.

Chocolate chips: Add pockets of melted chocolate throughout the loaf. Chocolate chunks also work well if you prefer larger pieces of chocolate in each slice.

Troubleshooting Sourdough Discard Banana Bread

Why did my banana bread sink in the middle?
It may have been underbaked, the batter may have been overmixed, or the oven door may have been opened too early. Bake until the center is fully set and a toothpick comes out with moist crumbs rather than wet batter.

Why is my banana bread dry?
Too much flour or baking it too long can dry out the loaf. Spoon the flour into the measuring cup and level it off, then begin checking the bread near the lower end of the baking time.

Why is my banana bread gummy?
A gummy center usually means the loaf needs more time in the oven or was sliced before it cooled. Let it cool for at least 30 minutes before cutting.

Why did the chocolate chips sink?
Very thin batter can allow the chips to fall. Tossing them with a teaspoon of flour before folding them in may help keep them more evenly distributed.

Why is the outside done before the center?
Loosely cover the top with foil once it is golden brown, then continue baking until the center is done.

    I keep coming back to this recipe. I can't hop it enough. Banana bread is something I don't eat, but my kids devour. For whatever reason, some weeks they won't even touch the banana, so I end up with no choice but to make banana bread. This recipe is so perfect! The sourdough makes me like I'm feeding my kids well. They always eat the whole loaf, and there are only 5 of them! It's that good!

    I love fermenting this overnight for better digestibility, and it is honestly one of the best things to have sitting on the counter.

    This recipe is perfect! I made it into muffins just for convenience of individual portions. All 5 of my kids loved them, which is a huge win. We’ve tried a lot of recipe and this was our favorite so far.
