💭Crucial Success Tips

Use very ripe bananas for the best sweetness and moisture. Measure after mashing if you can so the batter stays balanced. Mix gently so you don't make the muffins tough. Start checking at 20 minutes since ovens vary. Let them cool in the pan for a few minutes so they set up and don't fall apart.

Recipe FAQs

Can I use active sourdough starter instead of sourdough discard in sourdough discard muffins?

Yes. Use the same amount. The method and bake time stay the same, since starter won't really have time to do anything.

How ripe do the bananas need to be for sourdough discard banana muffins with chocolate chips?

The riper, the better. Lots of brown spots or mostly brown skins give the best sweetness and moisture.

Why did my sourdough discard muffins turn out dense or gummy?

Usually it's from overmixing, too much banana, or underbaking. Stir just until combined, measure mashed banana if possible, and bake until a toothpick comes out with a few moist crumbs, not wet batter. Cooling helps the crumb finish setting.

How To Store Banana Muffins with Chocolate Chips

Store at room temperature for 1 day. After that, refrigerate for up to 4 days.

They freeze very well once fully cooled. Store in an airtight container and thaw as needed.
