How many calories are in one cup of mashed bananas?

One cup of mashed bananas contains about 200 Calories. The exact amount varies with banana size and ripeness, but a cup of mashed fruit typically weighs roughly 225 grams, making this a useful rounded nutrition estimate.

Bananas supply most of their energy from carbohydrates, including natural sugars and starch. As bananas ripen, some starch changes into sugar, making the fruit sweeter without dramatically changing its total calorie content. Mashing changes the texture and volume, but it does not add calories unless ingredients such as milk, butter, or sugar are mixed in.

A common mix-up is confusing one cup of sliced bananas with one cup of mashed bananas: the two measures can hold different weights. Banana calories are also sometimes overstated because people associate the fruit with its carbohydrate content. For comparison, raw banana provides about 89 Calories per 100 grams, so a generously filled cup lands near the 200-Calorie mark. Bananas are also known for potassium, vitamin B6, and dietary fiber.
