227 g of mashed bananas is 1 cup. That is the whole answer: one US cup of mashed bananas weighs 227 g (spooned and levelled, King Arthur Baking), so 227 g divided by 227 g per cup is exactly 1 cup. All the figures on this page are approximate — mashed bananas is a natural product, and how it is measured moves the weight of a cup by a few grams — so when the recipe is delicate, verify with a kitchen scale. For everyday cooking, 1 cup is the number to use.

This page is the reverse of the usual conversion: most recipes list mashed bananas in cups and the cook wants grams, but here the recipe, the packet or the scale gives grams and the cook has only cup measures. That happens more often than people expect — imported recipes, nutrition labels, bulk packs and meal-prep plans all speak in grams, while American cup measures are what is actually in the drawer. The conversion is one division, 227 ÷ 227 = 1, and the table below runs the same division for the amounts that come up most often.

227 grams of mashed bananas in cups — conversion table

Grams Cups (approx.)
10 g 0.04 (0 cups)
25 g 0.11 (1/8 cups)
50 g 0.22 cups
75 g 0.33 (1/3 cups)
100 g 0.44 cups
125 g 0.55 cups
150 g 0.66 (2/3 cups)
200 g 0.88 (7/8 cups)
250 g 1.10 (1 1/8 cups)
300 g 1.32 (1 1/3 cups)
400 g 1.76 (1 3/4 cups)
500 g 2.20 cups

Read the table from left to right: find the grams you have, and the cups column tells you how much that is, approximately. A quarter of a cup is 57 g, half a cup is 114 g, and three quarters is 170 g. For amounts between the rows, divide the grams by 227: for example, 170 g is 0.75 (3/4 cups), and 340 g is 1.50 (1 1/2 cups). The same 227 g figure works in the other direction too — multiply cups by 227 to get grams — and the second table runs that calculation for the common cup fractions.

Cups Grams (approx.)
1/4 cup 57 g
1/3 cup 76 g
1/2 cup 114 g
2/3 cup 151 g
3/4 cup 170 g
1 cup 227 g
1 1/2 cups 340 g
2 cups 454 g

Scaling a spice blend for a market stall or a big batch

A rub or curry powder made in bulk from a recipe written in grams. Take the 114 g figure first: 114 g of mashed bananas is 0.50 (1/2 cups), because 114 divided by 227 is 0.50. In practice that means a recipe calling for 0.50 (1/2 cups) can be weighed out as 114 g and poured or spooned straight in, with no jug to wash. The habit to build is converting once, writing the cup figure on the recipe, and then cooking from the cups — the scale only comes out for the first batch, and after that the converted recipe is a cup recipe. If the amount is awkward, round to the nearest tablespoon: one tablespoon of mashed bananas weighs about 14.2 g, so a couple of spoonfuls either way covers most rounding gaps without anyone noticing in the finished dish.

A bakery that buys leavener by the kilo

A professional kitchen converting a bulk bag into cup measures for a daily bake. Take the 340 g figure first: 340 g of mashed bananas is 1.50 (1 1/2 cups), because 340 divided by 227 is 1.50. In practice that means a recipe calling for 1.50 (1 1/2 cups) can be weighed out as 340 g and poured or spooned straight in, with no jug to wash. The habit to build is converting once, writing the cup figure on the recipe, and then cooking from the cups — the scale only comes out for the first batch, and after that the converted recipe is a cup recipe.

A preserving or pickling recipe written in grams

A spice mix where the exact balance keeps the flavour right across dozens of jars. Take the 454 g figure first: 454 g of mashed bananas is 2.00 (2 cups), because 454 divided by 227 is 2.00. In practice that means a recipe calling for 2.00 (2 cups) can be weighed out as 454 g and poured or spooned straight in, with no jug to wash. The habit to build is converting once, writing the cup figure on the recipe, and then cooking from the cups — the scale only comes out for the first batch, and after that the converted recipe is a cup recipe.

When the conversion matters — and when it does not

It matters whenever the ingredient is potent: a leavener that is over-measured makes cakes taste soapy and collapse, and a spice that is over-measured by a whole cup would ruin a dish outright. These pages are really for bulk cooks — in a home recipe, weigh the grams and use tablespoons instead.

The practical rule is simple: if mashed bananas is doing chemistry in the recipe — setting a batter, thickening a sauce, balancing an acid — weigh it. If it is doing flavour or bulk, cups are fine. A cook who weighs the fussy ingredients and measures the forgiving ones in cups gets the best of both systems: accuracy where it counts, speed everywhere else. And that is the real point of a page like this one. It is not about the arithmetic, which is one division; it is about knowing which recipes forgive a rounded cup and which ones punish it, so the scale comes out on the right days and stays in the drawer on the others.

A note on mashed bananas itself

Very ripe bananas mashed to a pulp. In the kitchen it is used for banana bread, pancakes, smoothies and egg replacement. Storage is straightforward: use fresh; freeze overripe bananas for baking. None of that changes the conversion, but it explains why the same ingredient keeps appearing in recipes from different traditions, written in different units. A cook who knows the ingredient, the 227 g figure and the spooned and levelled method can follow any of them without converting on the fly.

Frequently asked questions

How should I measure mashed bananas for a normal recipe?

By weight or by spoon, never by the cup. One tablespoon of mashed bananas weighs about 14.2 g, which is the practical unit for everyday cooking.

Why is the spooned-and-levelled method important here?

Because scooping a powder straight from the jar compresses it and can add a quarter or more to the weight. Spoon the powder into the measure and level it with a straight edge.

Does humidity change the weight?

Yes — powders absorb moisture from the air, especially above a stove or in a steamy kitchen, and clump. Store mashed bananas in an airtight jar in a cool, dry place and the conversion stays stable.

Can I use volume instead of weight for mashed bananas?

For a pinch or a teaspoon, volume is fine. For a whole cup or a bulk batch, weigh it: a cup of powder is the least reliable measure in the kitchen.

How many cups is 227 g of mashed bananas?

About 1 cup — 227 g divided by 227 g per cup. The figure is approximate, because fine powders compact differently depending on how they are spooned.
