Why It’s Best To Bake With Brown Bananas
Ripe bananas are not only softer, and therefore easier to mash and blend into a batter, but they are also sweeter, which is why baking recipes specifically call for ripe bananas in ingredient lists. As the bananas ripen, the fruit converts starches to sugars, which makes them not only sweeter but more flavorful.

If you’ve ever had a slice of banana bread that barely tastes of banana it’s probably because the bananas used weren’t quite ripe enough.

Plus, using brown bananas prevents baked goods from becoming gummy or starchy in texture, which often happens when green or under ripe bananas are used.
