Cast Iron Banana Bread

We’ve all been there: you have three bananas on the counter that nobody is going to eat. They went spotty two days ago and then they went past spotty, and every morning you move them a little further down the counter like that will change something.

This is the recipe that saves them, and it has saved a lot of bananas over the years, because it is simple enough to start without thinking and forgiving enough that it comes out well even when I am only half paying attention.

I bake this in a cast iron loaf pan, but this recipe works in a regular metal or glass loaf pan as well.

Why cast iron makes a better banana bread

Cast iron holds heat differently than a thin metal or glass pan. It takes longer to come up to temperature and then it stays there, so the sides and bottom of the loaf get steady contact with real heat for the full hour instead of the fluctuating warmth you get from lighter pans. What comes out is a crust that is properly browned and slightly crisp at the edges while the middle stays soft and dense the way banana bread should be.

There is also the practical side of it, which is that a well seasoned cast iron loaf pan releases the bread without issue. I butter mine anyway out of habit, and the loaf comes out clean every time.

If you do not have a cast iron loaf pan, this bakes just fine in a standard nine by five. Start checking it around fifty minutes since lighter pans tend to run a little faster.

Recipe notes

Folding the ingredients together works better than mixing. Banana bread relies on baking soda instead of yeast, so every extra stir after the flour goes in builds more gluten and turns a tender loaf rubbery. Fold slowly with a rubber spatula and stop as soon as the dry flour disappears. A few small lumps are fine, and they bake out.

Warm banana bread is the best, but I have cut into a warm loaf plenty of times and regretted it, so it’s better to wait until the loaf is completely cool.

The bread is still setting as it cools, so if you cut into it too soon, the loaf will get gummy and dense.

How to tell when it is done

The center should be set with no wet gloss on top, and a knife or skewer inserted into the middle should come out with a few moist crumbs clinging to it rather than raw batter. If the top is browning faster than the inside is cooking, lay a piece of foil loosely over the pan for the last fifteen minutes.

Cast iron will often need the full hour and sometimes a few minutes past it, since the pan takes longer to heat through in the first place.

Variations and storage

The bananas. Riper is better. The ones that have gone soft and freckled and a little smelly are exactly what you want, because the starches have converted to sugar and both the flavor and the sweetness come through stronger. Bananas that are still firm and yellow will give you a paler, blander loaf.

Freezing bananas ahead. When bananas get away from me faster than I can bake, I peel them and put them in a bag in the freezer. Thaw them in a bowl before using and add the liquid that collects with them, since that is concentrated banana flavor.

Adding nuts. Fold chopped walnuts or pecans in with the last of the flour so they distribute without you having to stir extra.

Storing it. Wrapped well and kept at room temperature, the loaf holds for about three days and it is arguably better on day two once the spices have settled. It also keeps well in the fridge or freezer, sliced or whole.

Frequently asked questions

Can I make this without a cast iron pan? Yes. A standard nine by five metal or glass loaf pan works well. Start checking for doneness around the fifty minute mark since lighter pans bake a little faster.

Can I reduce the sugar? You can drop it to a third of a cup if your bananas are very ripe and you prefer a less sweet loaf. Going much lower than that starts to affect the texture and the browning.

Can I use whole wheat flour? Substituting half the all purpose flour with whole wheat works nicely and gives the loaf a nuttier flavor. Replacing all of it makes a noticeably denser and drier bread.

Does the alcohol cook out? Most of it does over an hour at 350°F. If you would rather not use it at all, two teaspoons of vanilla is a great substitution.

Why did my banana bread turn out tough? Almost always overmixing. Once the flour goes in, fold gently and stop as soon as it is incorporated.
