1/4 Cup Mashed Bananas in Grams
1/4 cup of mashed bananas weighs 56.8 g (spooned and levelled, King Arthur Baking). Very ripe bananas mashed to a pulp. All the figures on this page are approximate conversions based on the King Arthur Baking value of 227 g per cup, so when a recipe really matters, verify with a kitchen scale.
Why a quarter cup is worth weighing
It is tempting to eyeball a quarter cup and move on, but a quarter cup is where volume measuring is at its worst. Small cups pack differently from large ones, a heaped measure is easily a third over, and the ingredient itself — how fine it is ground, how damp it is, how settled the jar is — changes what fits in the cup. Grams cut through all of that: the weighed amount is the same whatever the brand, the humidity or the size of your measuring cup.
Spooned and levelled is the method behind the number, and it matters. Mashed Bananas is used for banana bread, pancakes, smoothies and egg replacement. That range of uses is part of why the conversion comes up so often: the same ingredient appears in everyday cooking and in precise baking, and the two situations demand different levels of accuracy. Grams cut through all of that: 56.8 g of mashed bananas is 56.8 g whatever the brand, the humidity or the size of your measuring cup.
Mashed Bananas cups to grams conversion table

| 1/2 cup | 113.5 g | 8 |
| 2/3 cup | 151.3 g | 10.7 |
| 3/4 cup | 170.2 g | 12 |

| 1 1/2 cups | 340.5 g | 24 |
| 2 cups | 454 g | 32 |
The tablespoon column shows how many tablespoons each amount equals: a quarter cup is 4 tablespoons, and one tablespoon of mashed bananas weighs about 14.2 g. A cup is 16 tablespoons, so the numbers in the table are just the cup weight divided by 16, rounded to one decimal place. For small amounts a scale that reads to the gram is far more reliable than a spoon, because a heaped tablespoon can weigh half as much again as a level one. Read the table from the 1/4-cup row outwards: every row is the cup weight times the fraction, so scaling a recipe up or down is simple multiplication.
How the weight was measured
Spooned and levelled means the ingredient is measured the way King Arthur Baking measures it: spooned and levelled. For mashed bananas, that gives 227 g per cup, and a quarter of that is 56.8 g. The source for the figure is King Arthur Baking, and the confidence in the value is high. King Arthur Baking publishes a standard ingredient weight chart that recipe developers use as a reference, and this page follows it exactly rather than averaging across sources, because an average of two different measuring methods is a number that matches nobody's cup.
Worked examples
A mini banana bread
A mini banana bread baked in a small loaf tin uses 1/4 cup of mashed bananas — 56.8 g — which is about half a large banana. The banana is the moisture and the sweetness of the bread, and the weighed amount matters because bananas vary in size: a small banana mashed is 80 g, a large one is 150 g, and the difference decides whether the loaf is moist or soggy. Weigh 56.8 g of mashed banana, use very ripe bananas with black spots, and the bread will be the same every time.
Pancakes for two
A pancake breakfast for two people uses 1/4 cup of mashed bananas, 56.8 g, mixed into the batter with an egg and a little flour. The banana replaces the sugar and most of the liquid, so the pancakes are sweet without added sugar and stay soft for longer. Weigh the mashed banana, mash it until there are no lumps, and cook the pancakes on a medium heat — the natural sugars brown fast, so a hot pan burns them.
A smoothie bowl for one
A smoothie bowl for one person uses 1/4 cup of mashed bananas, 56.8 g, blended with yogurt and berries and topped with granola. The banana is the body of the bowl: it makes the smoothie thick enough to eat with a spoon, which is the whole point of a smoothie bowl. Weigh the banana, use a frozen one for a thicker result, and blend it until completely smooth.
When a quarter cup matters
The quarter cup is the measure of the careful cook: the test bake, the single serving, the small jar of seasoning, the sauce for two. In each of those cooks the ingredient is doing real work, and the amount decides the result. A scale turns a guess into a number you can repeat next week, which is the whole point of writing a recipe down in the first place.
Mashed bananas are the ingredient where ripeness changes everything: a green banana is starchy and firm, a black-spotted banana is sweet and soft, and the two behave completely differently in a bake. A quarter cup of mashed banana — 56.8 g — should come from a very ripe banana, mashed until smooth, because lumps of banana in a batter bake into wet pockets. Weigh the mash, not the banana: peel weight varies, and a banana that weighs 120 g with its skin is about 80 g without it.
Scaling a quarter cup up and down
Scaling from a quarter cup is straightforward once the base number is fixed — the table above does the work, but the pattern is worth knowing by heart. Doubling a recipe that calls for 1/4 cup means weighing 113.6 g; halving it means 28.4 g, which is 2 tablespoons. A full cup is 227 g, and two cups is 454 g. Writing the recipe in grams at this point is worth doing: the next time you make it, you weigh 56.8 g straight into the bowl and skip the measuring cup altogether. If you are scaling a recipe for a different tin size, convert every ingredient to grams first and then multiply — scaling by volume compounds the error on every ingredient at once, while scaling by weight keeps each one exact.
Common mistakes with mashed bananas
- Using a just-yellow banana for banana bread. It is starchy, not sweet, and the bread tastes flat. Use bananas with black spots — the riper, the sweeter and the softer.
- Mashing the banana in the bowl with the other ingredients. Lumps of banana survive the mixing and bake into wet pockets. Mash the weighed banana separately until smooth, then add it.
- Scooping the cup through the bag or jar. Scooping packs the ingredient down and can add a fifth or more to the weight. Spoon it in lightly and level it off with a knife.
- Measuring over the mixing bowl. Levelling over the bowl drops the excess straight into the batter, so you have added ingredient you did not intend. Level over the bag or the sink.
Storage and handling
Use fresh; freeze overripe bananas for baking. Keeping mashed bananas stored properly also keeps its weight per cup stable: an ingredient that has absorbed moisture from the air weighs more per cup than a dry one, so a sealed container is not just about freshness, it is about measurement accuracy too. If a bag or jar has been open for months in a humid kitchen, the first thing to do before a precise bake is to weigh the ingredient rather than trusting the cup. Label the container with the conversion — 1/4 cup is 56.8 g — and the next person to cook with it will thank you.
Frequently asked questions
How many grams is 1/4 cup of mashed bananas?
1/4 cup of mashed bananas weighs 56.8 g, measured spooned and levelled according to King Arthur Baking. That is one quarter of the full-cup weight of 227 g, and it is the figure to use when converting a recipe from cups to grams. All the figures on this page are approximate, so when a recipe really matters, verify with a kitchen scale.
How many tablespoons is 1/4 cup of mashed bananas?
There are 4 tablespoons in a quarter cup, whatever the ingredient. One tablespoon of mashed bananas weighs about 14.2 g, so 4 tablespoons come to about 56.8 g. For small amounts like this, a scale that reads to the gram is more reliable than spoons, because a heaped tablespoon can weigh half as much again as a level one.
How do I measure 1/4 cup of mashed bananas without a scale?
Mashed Bananas is measured spooned and levelled, according to King Arthur Baking. Spoon it into a 1/4-cup measure, level the top with the back of a knife, and you will be close to 56.8 g. That is the best you can do without a scale — but be honest with yourself that it is an estimate. A basic digital kitchen scale costs less than a bag of good flour and removes the guesswork from every recipe, not just this one.
What is mashed bananas used for?
Banana bread, pancakes, smoothies and egg replacement. Very ripe bananas mashed to a pulp. A quarter cup — 56.8 g — is a common amount in small batches, sauces, dressings and test bakes, which is why this conversion comes up so often.
How many bananas is 1/4 cup mashed?
About half a large banana, or one small one. A large banana gives about 1/2 cup mashed, so a quarter cup — 56.8 g — is half of one. Weigh the mash rather than counting bananas, because bananas vary in size.
Can I freeze bananas for baking?
Yes — freeze overripe bananas whole, in their skins, and thaw them when you need them. They go soft and dark, which is perfect for baking. Weigh 56.8 g of the thawed mash and use it straight away.
