How Many Bananas in a Cup?

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.
