How to Make This Brown Butter Sourdough Banana Bread, Step-by-Step
Let’s roll up our sleeves and get baking! This recipe is straightforward, making it perfect for cooks of all skill levels. Here’s how to create this delicious loaf:
1. Preheat the oven to 350°F. Grease and line a standard (9×5”) loaf pan with parchment paper. Set it aside.
2. In a saucepan over medium-high heat, add the salted butter and let it melt. Allow it to cook for about 5 minutes until it turns a lovely golden brown, releasing a nutty aroma. Remove it from the heat and pour into a large bowl to cool slightly.
3. In a separate medium bowl, whisk together the all-purpose flour, baking soda, baking powder, cinnamon, and salt. Set this aside for later.
4. Once the brown butter has cooled a bit, add the brown sugar and whisk until combined.
5. Next, add the eggs and vanilla extract, whisking until everything is well combined. Then, stir in the mashed bananas, sourdough discard, and Greek yogurt until you have a smooth mixture.
6. Gently fold the dry ingredients into the wet ingredients using a wooden spoon or spatula, being careful not to over-mix. A few lumps are perfectly fine!
7. Finally, fold in the chocolate chips. Pour the batter into your prepared loaf pan. If you’d like, sprinkle a few extra chocolate chips on top for good measure. Use a butter knife to score a long line down the middle of the batter lengthwise to create a lovely seam while baking.
8. Bake in the preheated oven for 60-65 minutes, or until golden brown and a toothpick inserted into the center comes out clean or with a few moist crumbs.
9. Let the loaf cool in the pan for about 5-10 minutes before transferring it to a cooling rack or serving plate.
10. Slice and serve warm, perhaps with a little butter and a sprinkle of flaky sea salt on top. Enjoy this warm, inviting treat with your loved ones!

Pro Tips for the Best Results
As with any recipe, I’ve learned a few tips along the way that can help you achieve the best results:
- Use Overripe Bananas: The riper the bananas, the sweeter and more flavorful your bread will be. Don’t hesitate to use those brown, spotty ones!
- Don’t Overmix: Mixing too much can lead to dense bread. Just combine until you can’t see any more flour streaks—lumpy is okay!
- Check for Doneness: Ovens can vary, so keep an eye on your bread. If it’s browning too quickly, cover it loosely with foil.
Serving Suggestions
This Brown Butter Sourdough Banana Bread is perfect on its own, but there are plenty of ways to elevate it even further:
- Serve warm with a pat of salted butter for that extra indulgence.
- Add a drizzle of honey or maple syrup for a sweet touch.
- Pair it with a dollop of whipped cream or a scoop of vanilla ice cream for a dessert twist!
- Enjoy it alongside a warm cup of coffee or tea for the perfect cozy afternoon.
Storage and Make-Ahead Tips
This banana bread is a great make-ahead option! Here are some storage tips:
- Store leftover banana bread in an airtight container at room temperature for up to 3 days. If you want to keep it longer, you can refrigerate it for up to a week.
- For longer storage, wrap the cooled loaf tightly in plastic wrap and then in aluminum foil, and freeze for up to 3 months. When you’re ready to enjoy it, simply thaw it at room temperature.
- Feel free to slice the loaf before freezing, so you can pull out just what you need at any time!
So there you have it, my friends! This Brown Butter Sourdough Banana Bread is not just a recipe; it’s an invitation to create sweet memories together. Whether you’re baking it for yourself or sharing it with loved ones, know that every bite is filled with warmth and love. Happy baking!
