About One Bowl Banana Bread
Banana bread is a classic baked treat that has become a to-go for both enjoying and gifting, and for very good reason:
The natural sugars in bananas will caramelize as they bake, helping give this bread the deep, old-fashioned flavor that so many have come to love.
And better yet, banana bread is easy to make. This particular recipe can be made with only one bowl, meaning you can whip up a tastefully moist loaf of bread without decimating your kitchen.
Because really, who has time to worry about cleanup when you’ve got slices of homemade bread to devour?

How ripe should bananas be for banana bread?
Depending on your patience, bananas should be as close to completely black as possible. Or, at the very least, the bananas should be 70% black or more. Very minimal yellow should be showing.
How to ripen bananas
Ready to make some banana bread but don’t want to wait for the bananas to ripen on their own? No problem! You can speed up the process with near-identical results.
To ripen bananas:
- Preheat your oven to 300 degrees F. Cover a baking sheet with parchment paper. Note: The parchment paper isn’t required, but the bananas will leak a little during this process. The paper just makes cleanup a little easier.
- Lay the banans in a single layer on the baking sheet.
- Bake for about 40 minutes or until the skin of the bananas is a shiny black color.
- Let bananas cool for about 30 minutes before using. You can also toss them in the fridge to speed up the process.
Easy, right? And it actually works! If you’d like to see, this is what the bananas looked like before:

And this is what they looked like after:

How long does banana bread last?
Once prepared, this bread can be stored on the counter in a sealed container (or in plastic wrap) for up to four days. And like most homemade breads, the flavor of this loaf will intensify after one or two days.
After the fourth day, the texture of the bread may change as it begins to dry out. Banana bread can still be eaten on the fifth or sixth day, but you may want to toast the bread so it’ll be harder to notice any change in texture.

Can you freeze banana nut bread?
Yes, you totally can!
When stored in an airtight container or freezer bag, this bread will keep its “best” quality for about two or three months. After that point, the texture of the bread might change, but it will remain good for up to six months frozen.
