How to Make Sourdough Banana Bread (Overview)
Making sourdough banana bread is super easy! Start by mashing your bananas and mixing them with your sourdough discard and other wet ingredients. Then, whisk together the dry ingredients before combining the two. Simply fold in those crunchy walnuts and spread it all into a loaf pan. Top it with your delightful streusel and pop it in the oven. Pro tip: set a timer for halfway through and check if it’s browning too quickly; a little foil can fix that!
How to Serve Sourdough Banana Bread
Once it’s out of the oven, the surface will have a golden hue while the inside remains moist and dreamy. Serve it warm, sliced thick with a pat of butter melting into the crevices (yum!). You can also enjoy it with a scoop of ice cream on the side or topped with a drizzle of honey. Talk about indulgence! 🍯
How to Store Sourdough Banana Bread
Got leftovers? No problem! This banana bread lasts about 3–4 days at room temperature if stored in an airtight container, or you can refrigerate it for up to a week. If you want to keep it for longer, freeze slices in a zip-top bag for up to 3 months. Just pop it in the toaster for a quick reheat later!
Tips to Make Sourdough Banana Bread
- Use very ripe bananas for the best flavor—think brown spots!
- Swap out walnuts for chocolate chips or dried fruit for a fun twist.
- For extra moisture, add a tablespoon of yogurt or applesauce to the batter.
- Don’t skip the streusel; it adds a delightful crunch on top!
- If your batter seems too thick, a splash of milk can help loosen it up.
Variation
Looking for a twist? Try adding spices like nutmeg or ginger for a warm, spiced flavor. Feel free to go vegan by replacing the egg with flaxseed meal or applesauce and using coconut oil instead of butter. You can also toss in some cocoa powder for a chocolatey delight!
