This sourdough discard banana bread has become one of my favorite things to make in the late summer. It has all the delicious banana flavor, of course, but the cinnamon and brown sugar creates a little nod to fall! I’ve also discovered that bananas can last for ages in the fridge, so when they’re starting to look a little overripe, I toss them in the back of the fridge where they can hang out until I’m ready to bake. I’ve really enjoyed a slice of this banana bread with a hot Chai in the morning, or after dinner with a little bit of vanilla ice cream.
