Why You’ll Love This Recipe

This sourdough discard banana bread hits all the cozy notes—moist, perfectly sweet, and kissed with just a hint of tangy sourdough magic. The overripe bananas bring that irresistible natural sweetness and dense texture, while the sourdough discard creates a subtle depth of flavor you never realized banana bread was missing. It’s practical, too—rescue those spotty bananas and give your sourdough starter a second life. No waste, all comfort.

Pro Tip: This is a one-bowl wonder that keeps cleanup minimal. Perfect for slow mornings or when you’re craving something warm from the oven without the fuss.

Ingredient Breakdown

Let’s talk ingredients! The 250g of overripe bananas are the heart and soul here. The browner, the better—they’re sweeter and mash like butter. The sourdough discard gives the bread that gentle tang, but don’t worry, it won’t overpower the flavor. This recipe uses a mix of brown sugar (for moisture) and an optional 50g of white sugar for added sweetness. A pinch of salt amps up every flavor, and melted butter delivers that rich, bakery-worthy decadence.

If you’re low on an ingredient, here’s some flexibility:

Original Ingredient	Swap Idea	Optional Add-Ons
Sourdough Discard	Fed Starter	Chocolate Chips
Brown Sugar	Coconut Sugar	Chopped Walnuts
Melted Butter	Neutral Oil	Cinnamon-Sugar Topping

How to Make It Step-by-Step

Start by preheating your oven to 350°F (175°C) and lining a standard loaf pan with parchment paper. Mash the bananas in a large bowl until smooth—chunks are okay, because we’re after cozy, homemade vibes. Whisk in the sourdough discard, melted butter, egg, and vanilla extract until combined. Add the brown sugar (plus the white sugar if you’re using it), and mix gently.

In a separate small bowl, stir together the flour, baking powder, and salt. Gradually fold this dry mixture into the wet ingredients using a spatula. Be gentle—overmixing can make your bread dense. Pour the batter into the prepared loaf pan and smooth the surface.

Pro Tip: To ensure even rising, give the pan a little tap on the counter to settle the batter before baking.

Troubleshooting and Timing

If you’ve ever had banana bread that’s too dense or sinks in the middle, here’s how to avoid it. First, double-check your baking powder is fresh—it’s the key to a perfect rise. Bake your loaf for 50–60 minutes, but start checking around the 50-minute mark. Insert a toothpick into the center; if it comes out clean or with a few moist crumbs, it’s ready.

Uneven baking? Make sure your oven rack is positioned in the middle of the oven for the most consistent heat.

Step	Approximate Time	Key Tips
Prepare Batter	10–15 mins	Don’t overmix
Bake	50–60 mins	Check doneness at 50 min
Cool	20–30 mins	Cool before slicing

Serving, Storage, and Tweaks

Let the banana bread cool in the pan for about 10 minutes, then transfer it to a wire rack to cool completely. Trust me, slicing too soon will make it crumble. Serve it fresh with a smear of butter—or toast slices the next day for a slightly crispy edge. Whatever speaks to your cozy-heart cravings.

For storage, wrap the loaf tightly in plastic wrap or keep it in an airtight container at room temperature for up to 3 days. Want to save some for later? It freezes beautifully—just slice it first for easy grab-and-go pieces.

Pro Tip: Feeling fancy? Brush the top with the golden syrup for a glossy, bakery-style finish. Or mix in chocolate chips, walnuts, or both for an extra treat.
