1 Cup Hazelnuts in Grams

1 cup of hazelnuts weighs 142 g (spooned and levelled, King Arthur Baking). Round, sweet nuts with a thin brown skin. All the figures on this page are approximate conversions based on the King Arthur Baking value, so when a recipe really matters, verify with a kitchen scale.

Why weighing hazelnuts beats measuring it in cups

Hazelnuts are the heaviest common nut per cup at 142 g, which surprises bakers who assume all nuts weigh the same. A cup of hazelnuts weighs nearly 30 g more than a cup of cashews, so a recipe developed with one nut and made with the other by volume alone will be off in both weight and texture. The round shape is part of the reason: hazelnuts are nearly spherical and settle into a cup with relatively little air space, unlike flat or irregular nuts that leave gaps.

The skin is the other detail that changes the number. Hazelnuts are usually sold with their thin brown skins on, and the skins weigh very little but take up almost no volume, so the 142 g figure applies whether the skins are on or off for practical purposes. What does change the weight is toasting and rubbing the skins off: a toasted, skinned hazelnut is slightly lighter per cup because a little moisture is lost. If a recipe calls for skinned hazelnuts, toast and skin them first, then weigh, rather than weighing the raw nuts and assuming the number still holds.

3 cups 426 g 48
4 cups 568 g 64

One tablespoon of hazelnuts weighs about 8.9 g, since a cup is 16 tablespoons. That is useful when a recipe calls for a spoonful or two rather than a whole cup, though 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.

Worked examples

Hazelnut praline for a celebration cake

A praline topping for a large cake uses about 1 1/2 cups of hazelnuts, which is 213 g. Toast the nuts at 180 C for about ten minutes until the skins loosen, rub them in a tea towel to remove most of the skins, then weigh 213 g and caramelise with 200 g of sugar. Weighing after skinning matters, because the skins and a little moisture are gone by then, and a cup measured before toasting will not weigh the same afterwards.

Nutella-style spread, one jar

A homemade chocolate hazelnut spread for one medium jar uses about 1 cup of hazelnuts, which is 142 g, blended with cocoa, sugar, oil and milk powder. Roast the nuts first and remove the skins, then blend while warm so the oils release and the spread turns smooth. The weight is what keeps the spread balanced: too many nuts and it turns stiff and grainy, too few and it is mostly sugar and cocoa.

Hazelnut and green bean salad for six

A warm salad for six people uses about 1/2 cup of toasted hazelnuts, which is 71 g, roughly chopped and scattered over green beans with a mustard dressing. Chop them after toasting so the pieces are uneven and crunchy, and weigh 71 g so the nuts garnish the salad rather than dominating it. Because hazelnuts are dense, half a cup looks smaller than half a cup of a lighter nut, and cooks who measure by eye tend to add too many.

How the weight was measured

The figure on this page comes from King Arthur Baking, measured spooned and levelled unless the method line says otherwise. Spooning means filling the cup with a spoon rather than plunging the cup into the bag, and levelling means sweeping a knife across the rim. Scooping packs the ingredient down and can add a fifth or more to the weight, which is why two bakers following the same cup-based recipe can get visibly different results.

Confidence in this value is high. That reflects how consistent the ingredient is from brand to brand: a uniform, factory-packed ingredient is more predictable than a fresh, variable one. Even a high-confidence figure is still an approximation, because moisture, grind size and settling all shift the weight a little. Treat the grams on this page as a reliable starting point and check with a scale when the recipe is fussy, expensive, or being made for the first time.

Practical guidance

Store hazelnuts in an airtight container in a cool, dry place, and refrigerate them for longer keeping, because their oils turn rancid within a few months at room temperature. Taste one before baking: a bitter or paint-like taste means the bag is past its best. To remove the skins, toast the nuts until the skins darken and loosen, then wrap them in a clean tea towel and rub firmly; most skins come away, and the few that remain do no harm. When a recipe calls for hazelnut flour, grind the nuts with a spoonful of the recipe's sugar or flour, which stops them clumping into butter. If you do not have a scale, spoon the nuts into the cup and level it, and remember the 142 g figure is approximate, so check the mixture rather than trusting the cup alone.

Common mistakes with nuts and seeds

The most common mistake is measuring whole nuts and chopped nuts as if they weighed the same. Chopped nuts pack tighter, so a cup of chopped pistachios weighs more than a cup of whole ones, and a recipe that calls for a cup of one and gets the other will be off by a noticeable margin. If a recipe says chopped, chop first and then measure, or better, weigh. The second mistake is using stale nuts: rancid oil in an old bag will flavour the whole bake, and no amount of sugar covers it. Taste one before you bake with it. The third is toasting by time instead of by smell: nuts go from toasted to burnt in under a minute, so stand at the oven and pull them when they smell fragrant, not when the timer says so. Finally, do not substitute one nut for another by volume alone in a recipe that depends on weight: a cup of cashews and a cup of hazelnuts differ by nearly 30 g, which changes the balance of a cake or a pesto.

Frequently asked questions

How many grams is 1 cup of hazelnuts?

1 cup of hazelnuts weighs 142 g when spooned and levelled, according to King Arthur Baking. The figure is approximate, and toasting or skinning the nuts changes it slightly, so verify with a kitchen scale when accuracy matters.

Why do hazelnuts weigh more per cup than cashews?

Hazelnuts are round and dense, so they settle into a cup with little air space, while cashews are curved and irregular and leave more gaps. A cup of hazelnuts is 142 g and a cup of cashews is 113 g, a difference of nearly 30 g per cup.

Do I weigh hazelnuts before or after removing the skins?

Weigh them after toasting and skinning if the recipe calls for skinned nuts, because the skins and a little moisture are lost in the process. The difference is small, but in a precise recipe such as praline it is worth getting right.

How many cups is 200 g of hazelnuts?

200 g of hazelnuts is about 1.4 cups, or 1 cup plus a generous 1/3 cup. At 142 g per cup, divide 200 by 142 to get the answer, and use a scale for the most accurate result.

Can I substitute hazelnuts for almonds by volume?

You can, but weigh them instead of measuring by volume, because a cup of hazelnuts is 142 g while a cup of almond flour is 96 g and whole almonds differ again. Matching by weight keeps the recipe balanced; matching by volume does not.
