How ripe should bananas be for banana bread?
Very ripe. You want heavy brown speckles or even mostly brown skins. If they smell strongly like banana and mash easily with a fork, you are in the sweet spot.
Can I use frozen bananas?
Yes. Thaw completely, then drain off excess liquid only if it looks extreme. A little banana liquid is flavor. Mash and measure as usual.
Why did my banana bread sink in the middle?
Common culprits are underbaking, too much banana, or overmixing. Bake until a toothpick comes out with a few moist crumbs, and avoid beating the batter once flour is added. Also, keep add-ins reasonable (see below) so the loaf is not weighed down.
How do I keep banana bread moist?
Do not overbake, wrap it once fully cool, and use brown sugar. Also, measure flour correctly. Spoon it into the measuring cup and level it off, or use a scale. Too much flour dries the loaf fast.
Can I make muffins instead of a loaf?
Absolutely. Bake at 350°F in a lined muffin tin for about 18 to 22 minutes, until a toothpick comes out with moist crumbs.
Can I reduce the sugar?
You can reduce the total sugar by 1/4 cup and it will still work, especially if your bananas are very ripe. The loaf will be a bit less caramelized on top.
What if I only have an 8.5x4.5 inch loaf pan?
That smaller pan makes a taller loaf, so it can take longer to bake. Start checking around 60 minutes total, and tent with foil if the top is getting too dark before the center is done. If you have extra batter, bake it as a couple of muffins so you do not overfill the pan.
How much can I add (nuts, chocolate, etc.)?
Try to keep total add-ins to about 1 to 1 1/2 cups. More than that can make the loaf heavy and encourage sinking.
Any quick high-altitude tweak?
If you bake at higher altitude and quick breads tend to sink, try reducing sugar by 1 to 2 tablespoons and adding 1 tablespoon flour. Keep an eye on doneness and use the toothpick and (if you have it) thermometer cues.
