How Many Bananas in a Cup?

Banana image

Many recipes will call for "1 cup of mashed bananas" or "1 cup of sliced bananas" but it can be a struggle to figure out actually how many bananas are in a cup. In order to help make cooking easier we did some experiments to help tell you exactly how many bananas you need to buy.

To answer How many bananas in a cup we bought several pounds of bananas and went to work. Each pound of bananas contains about 3 or 4 medium bananas so we decided to use a medium banana as our standard of measurement. We then sliced and mashed the bananas to figure out how many bananas were needed for a cup.

We determined that for a cup of mashed bananas there are about 3 bananas needed. And for a cup of sliced bananas you need 1.5 bananas.

Did you know that bananas don't grow on trees but are actually a giant herb in the same plant family as lilies, orchids, and palms. Today Hawaii is the only place in the U.S. where bananas are grown commercially, whereas India is the largest producer. More than 100 billion bananas are eaten every year in the world, making them the fourth most popular agricultural product.

Now you know that there's 3 mashed bananas in a cup. You can also use our conversion tool below for any custom "how many bananas in a..." measurements you need.

How to Store Banana

General How to Store Banana Info

Bananas release ethylene, which can spoil some produce stored nearby.

How to Ripen Banana

If you bought green bananas from the store and want to ripen them sooner, place the bananas in a paper bag for 2 to 3 days. This will speed up the ripening process. The skin may still appear green but the flesh will be soft and sweet.

Short Term Banana Storage

Keep bananas out in room temperature, away from high heat or direct sunlight, in a fruit bowl or on a banana hanger. Bananas will stay fresh for at least a week this way.

Once a banana has reached its peak of ripeness, you can keep them that way by putting the banana in the refrigerator. The skin will turn dark brown, but the fruit itself will remain ripe and sweet for 3 more days.

Banana Long Term Storage

Frozen bananas are mushy when defrosted, but the sweet flavor is retained; they are great for cooking and baking. Their skin will turn brown/black, but do not bother wrapping them, just place the bananas as is in the freezer.

Home canned bananas can be stored up to 1 year; they tend to lose quality after that point.

To dry bananas, peel and cut into 1/4 to 1/2 inch slices. Dry at 130 to 135°F (54.4 to 57.2°C) until almost crisp. Dried fruit can be stored 6 to 12 months at room temperature or indefinitely in the freezer.
