The riper, the better! You want them dark, spotty, and soft—this gives the bread its natural sweetness and moisture. If your bananas aren’t ripe yet, try baking them at 300°F for 15 minutes until the skins turn black.
2. Can I use frozen bananas?
Absolutely! Just thaw them first and drain any excess liquid before mashing. This helps keep the batter from getting too wet and ensures the bread bakes up perfectly.
3. What can I substitute for sour cream?
No sour cream? No problem! You can swap it for Greek yogurt, buttermilk, or even plain yogurt. These alternatives still give you that ultra-moist texture.
4. Why is my banana bread dense or gummy?
Overmixing is the culprit! Stir the batter just until combined—a few lumps are okay. Also, make sure you’re measuring flour correctly (fluff, scoop, and level!) and baking it long enough.
5. Can I make this ahead of time?
Yes! This banana bread stays moist for days at room temperature when wrapped well. It also freezes beautifully—just slice it, wrap it in plastic, and store it in an airtight bag for up to 3 months.
Now you’ve got all the tips for the best banana bread ever!
