3/4 Cup Mashed Bananas in Grams
3/4 cup of mashed bananas is 170.2 g on a kitchen scale (spooned and levelled, King Arthur Baking). Very ripe bananas mashed to a pulp. A full cup weighs 227 g, and three quarters of a cup of that is 170.2 g. All the figures here are approximate conversions, so verify with a scale when the recipe really matters.
Getting 3/4 cup right the first time
Getting 3/4 cup right the first time matters because mashed bananas is not an ingredient you can easily correct after the fact. Once it is mixed into a batter, a dough or a sauce, you cannot take it out, and adding a little more of something else to compensate usually makes things worse. The recipe was tested with 170.2 g, measured spooned and levelled, and the closer you stay to that, the closer your result stays to the one the recipe writer tasted. A scale is the only tool that tells you, before you mix anything, that you are on target.
Worked examples
Doubling and halving from 3/4 cup
Halving a recipe is where 3/4 cup appears most often in real kitchens. A recipe written for a family might call for 1 1/2 cups of mashed bananas; halved, that is 3/4 cup, or 170.2 g. The trap is halving by volume: half of 1 1/2 cups is easy to say and hard to measure, because few cup sets have a 3/4-cup measure and fewer still have a 1/3-cup one. Weighing 170.2 g sidesteps the problem entirely. And if you are doubling instead, two lots of 3/4 cup is 1 1/2 cups, which is 340.5 g — again, one number on the scale, no cup juggling, and the recipe stays in proportion.
Scaling a recipe that calls for 3/4 cup
A recipe for a smoothie bowl base calls for 3/4 cup of mashed bananas, and you want to make one and a half times as much for guests. On the scale that is simple: 170.2 g times 1.5 is 255.4 g, and you weigh it straight into the bowl. Doing the same sum in cups means measuring a cup and an eighth, which no measuring cup marks, so most people guess — and guessing is how a good recipe goes wrong. The same logic works in reverse: halve the recipe and you need 85.1 g, which is 85.1 g on the scale and a fiddly 6 tablespoons by volume. mashed bananas is used for banana bread, pancakes, smoothies and egg replacement, and the weighed amount keeps the ratio right at any scale.
A small batch built around 3/4 cup
Sometimes 3/4 cup is the whole point of the recipe, not a fraction of it. A small batch of a summer berry crumble for two people often needs just 3/4 cup of mashed bananas — 170.2 g — alongside the other ingredients, and at that scale there is nothing to hide behind: too much and the result is heavy or overpowering, too little and it is bland or falls apart. Weigh the 170.2 g first, before you start mixing, so you know the foundation is right. Once you know that 3/4 cup is 170.2 g, you can scale the same recipe up for four people by doubling to 340.5 g without ever touching a measuring cup, and the result will taste the same.

The tablespoon column shows how many tablespoons each amount equals: 3/4 cup is 12 tablespoons, and one tablespoon of mashed bananas weighs about 14.2. 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 3/4 cup row outwards: every other row is a multiple of 170.2 g, 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 three quarters of a cup of that is 170.2 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.
Practical guidance for mashed bananas
Fresh fruit is the least consistent thing you can measure by the cup, because no two pieces are the same size and the gaps between them depend on how they happen to fall. A cup of whole berries can hold far fewer grams than a cup of halved berries, simply because the halves nest together. That is why the 227 per cup figure for mashed bananas is an average, and why weighing is the only way to be sure: 170.2 on the scale is 170.2 whatever size the berries are. Hull or peel the fruit before weighing, not after, so the weight you measure is the weight that goes into the recipe. If the fruit is very ripe and juicy, handle it gently — crushed berries release juice, and the juice weighs something, so a cup that has been mashed in the measuring cup will read heavier than whole fruit in the same volume.
When the conversion matters most
3/4 cup of mashed bananas shows up in recipes where the ratio is doing real work. mashed bananas is used for banana bread, pancakes, smoothies and egg replacement, and in those recipes the amount is not decoration — it sets the texture, the structure or the flavour balance. In a sauce or a dressing, a few extra grams of mashed bananas can tip the balance; in a baked good, they can change the crumb. That is why recipes written in grams are worth following in grams: the recipe writer tested 170.2 g, not a cup that happened to be full that day. If you are cooking by feel, a cup is fine; if you are baking to a recipe, weigh it. The difference between the two approaches is the difference between a recipe that works every time and one that works on a good day.
Scaling 3/4 cup up and down
Once you know that 3/4 cup of mashed bananas is 170.2 g, the rest is arithmetic. A full cup is 227 g, half a cup is 113.5 g, and two cups is 454 g. Doubling a recipe that calls for 3/4 cup means weighing 340.5 g; halving it means 85.1 g, which is about 6 tablespoons. Writing the recipe in grams at this point is worth doing: the next time you make it, you weigh 170.2 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
- Measuring over the mixing bowl. Levelling over the bowl drops the excess straight into the batter, so you have added mashed bananas you did not intend. Level over the bag or the sink.
- Measuring whole fruit when the recipe wants it halved. Halves nest together and weigh more per cup than whole fruit. Prepare the fruit first, then measure.
- Using a liquid jug for a dry ingredient. A jug measures volume at eye level and has no straight edge to level against, so mashed bananas measured in a jug is a guess. Use a dry cup or a scale.
- Crushing the fruit in the cup. Pressing berries down releases juice and adds weight that was not in the recipe.
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 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 — 3/4 cup is 170.2 g — and the next person to bake with it will thank you.
Frequently asked questions
How many grams is 3/4 cup of mashed bananas?
3/4 cup of mashed bananas weighs 170.2 g, measured spooned and levelled according to King Arthur Baking. That is three quarters of a cup 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 3/4 cup of mashed bananas?
There are 12 tablespoons in 3/4 cup, whatever the ingredient. One tablespoon of mashed bananas weighs about 14.2, so 12 tablespoons come to about 170.2 g. For 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 3/4 cup of mashed bananas without a scale?
Mashed bananas is measured spooned and levelled, according to King Arthur Baking. Spoon it into a 3/4 cup measure, level the top with the back of a knife, and you will be close to 170.2 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 ingredients 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. 3/4 cup — 170.2 g — is a common amount in small batches and scaled recipes, which is why this conversion comes up so often.
How should I store mashed bananas?
Use fresh; freeze overripe bananas for baking. Good storage keeps the ingredient fresh and keeps its weight per cup consistent, because moisture absorbed from the air adds grams that the recipe did not ask for.
Can I scale a recipe that uses 3/4 cup of mashed bananas?
Yes — convert to grams first, then multiply. 3/4 cup is 170.2 g, a full cup is 227 g, and two cups is 454 g, so doubling means 340.5 g and halving means 85.1 g. Scaling by weight keeps every ingredient in proportion, while scaling by volume compounds the error on each one.
