One cup of dark chocolate chips weighs 170 grams when spooned and levelled, according to King Arthur Baking. That is a heavier cup than most people expect — heavier than a cup of flour at 120 grams, heavier than a cup of oats at 89 grams — because chocolate is dense and the chips pack together with very little air between them. A single tablespoon of dark chocolate chips weighs about 11 grams, and a quarter cup weighs about 43 grams. These are approximate figures, because chip size varies by brand — mini chips pack more densely than standard chips, and chunks pack less densely than chips — but 170 grams per cup is the reliable reference value, and you should verify with a kitchen scale whenever the amount matters.

Dark chocolate chips are the defining ingredient of the chocolate chip cookie, and the amount you use decides whether the cookie is a buttery biscuit with a few chocolate accents or a chocolate delivery vehicle barely held together by dough. Most recipes call for 1 to 2 cups, which is 170 to 340 grams, and the difference between those two amounts is the difference between two different cookies. Weighing the chips is also the only honest way to compare recipes: one writer's "2 cups of chocolate chips" and another's can differ by 40 grams depending on how generously they filled the cup, and 40 grams of chocolate is a lot of chocolate.

How much do dark chocolate chips weigh?

The table below gives the weight of dark chocolate chips for the amounts you are most likely to meet, from a single tablespoon up to four cups. All figures come from the King Arthur Baking value of 170 grams per cup, spooned and levelled. If your chips are mini chips, expect a cup to weigh a few grams more; if they are large chunks, expect a few grams less. Weighing removes the guesswork entirely.

Amount Weight (grams) Weight (ounces)
1 tablespoon 11 g 0.38 oz
1/4 cup 43 g 1.50 oz
1/3 cup 57 g 2.00 oz
1/2 cup 85 g 3.00 oz
2/3 cup 113 g 4.00 oz
3/4 cup 128 g 4.50 oz
1 cup 170 g 6.00 oz
1 1/2 cups 255 g 9.00 oz
2 cups 340 g 11.99 oz
3 cups 510 g 17.99 oz
4 cups 680 g 23.99 oz

A useful comparison: one cup of dark chocolate chips weighs exactly the same as one cup of chopped dark chocolate (170 grams) and the same as one cup of white chocolate chips (170 grams), because the density of chocolate is the same whichever form it is in. It is much heavier than a cup of cocoa powder, which weighs only 84 grams — cocoa powder is mostly air, while chocolate chips are solid. That comparison is a good reminder of why you cannot swap chocolate chips for cocoa powder by volume: a cup of chips carries twice the weight, and far more fat and sugar, than a cup of cocoa.

For everyday baking, the half-cup and one-cup rows are the ones that matter. A standard batch of chocolate chip cookies uses 2 cups (340 grams); a batch of muffins uses 1 cup (170 grams); a chocolate chip banana bread uses 3/4 cup (128 grams). If you are weighing ingredients, add the chips last: put the bowl on the scale, tare it, and pour the chips in until the number is right. It is faster than filling a measuring cup and far more accurate.

Worked examples

Example 1: The cookie recipe that never tastes like the bakery's

A bakery chocolate chip cookie recipe calls for 2 cups of dark chocolate chips — 340 grams. At home you measure 2 cups by volume, but your measuring cup is a generous one and you fill it to a slight mound, so you actually add about 380 grams. The cookies come out greasy and over-sweet, with pools of melted chocolate that make the dough spread too far. The bakery's cookies are balanced because they weigh 340 grams. The fix is simple: weigh the chips. At 340 grams the chocolate is generous but the dough still holds its shape, the cookies keep their crisp edges, and the flavour is butter and vanilla first, chocolate second — which is how a good chocolate chip cookie should taste.

Example 2: Scaling a muffin recipe for a bake sale

A muffin recipe calls for 1 cup of dark chocolate chips (170 grams) and makes 12 muffins. You need 48 muffins for a school bake sale, so you quadruple the recipe: 4 cups of chips, or 680 grams. If you measure four cups by volume, small errors compound — a cup that is 10 grams heavy becomes 40 grams heavy across four cups, which is nearly a quarter cup of extra chocolate. Weighing 680 grams once, in a single bowl on the scale, is faster and exact. It also tells you how many bags to buy: a standard 340-gram bag of chocolate chips is exactly 2 cups, so you need two bags for the quadrupled recipe.

Example 3: Converting a brownie recipe to grams

An American brownie recipe calls for 1 1/2 cups of dark chocolate chips, and you are converting it to grams for a friend in Europe. One and a half cups is 255 grams. The recipe also calls for 1/2 cup of chips folded into the top as a garnish — 85 grams. Knowing both numbers lets you buy the right amount: 255 plus 85 is 340 grams, exactly one standard bag. It also lets your friend check the recipe's balance: 255 grams of chips in a brownie batter that contains 200 grams of flour is a very chocolate-heavy brownie, which is useful to know before baking.

Method and source

The figure of 170 grams per cup comes from King Arthur Baking's ingredient weight chart, measured spooned and levelled: the chips are spooned or poured lightly into the cup and levelled off, without shaking the cup down or pressing the chips in. King Arthur lists the value with high confidence, and it agrees with the values printed on most chocolate chip bags, which typically state that a bag of 340 grams contains about 2 cups.

Chip size is the one variable that matters. Mini chocolate chips are smaller and pack together more tightly, so a cup of minis can weigh 175 to 180 grams. Large chunks and discs are bigger and leave more air gaps, so a cup can weigh 160 to 165 grams. Standard chips — the familiar teardrop shape about a centimetre across — are what the 170-gram figure describes. If your recipe was developed with standard chips and you are using minis, weighing is the only way to keep the chocolate content the same: a cup of minis by volume contains more chocolate than a cup of standard chips.

There is no serious dispute about the 170-gram figure itself. The confusion usually comes from people mixing up chocolate chips with cocoa powder (84 grams per cup) or with chocolate chunks measured loosely. Keep the forms separate, weigh rather than scoop, and the numbers are reliable.

Practical guidance

Dark chocolate chips are designed to hold their shape in baking: they contain less cocoa butter than bar chocolate and include stabilisers, so they soften but do not fully melt in the oven. That is why they are perfect for cookies and muffins, and why they are a poor choice for ganache or a chocolate sauce — for melting, use chopped dark chocolate instead, which has more cocoa butter and melts smoothly. If you do melt chocolate chips, do it gently in short bursts in the microwave or over a bain-marie, stirring often; overheated chips seize into a grainy paste.

The most common mistake with chocolate chips is measuring them by volume in a cup that has been shaken or tapped, which settles the chips and adds 10 to 20 grams per cup. The second is storing them badly: chocolate chips keep for up to a year in a cool, dry place, but heat makes them bloom — the cocoa butter rises to the surface and leaves a white, dusty coating. Bloomed chocolate is safe to eat and fine for baking, but it looks unappetising, so store chips away from the stove and out of sunlight. In a warm kitchen, the fridge is better than a hot cupboard, though the chips should come back to room temperature before baking so they do not chill the dough.

If you are out of dark chocolate chips, the best substitutes are chopped dark chocolate (use the same weight, 170 grams per cup) or white chocolate chips or milk chocolate chips (also 170 grams per cup, but sweeter and milder). Cocoa powder is not a substitute by volume — a cup of cocoa weighs only 84 grams and contains no cocoa butter, so a recipe that expects chips will fail. If you want a less sweet result, use chips with a higher cocoa percentage; if you want the chocolate to melt into the crumb rather than stay in distinct pieces, use chopped chocolate instead of chips.

Frequently asked questions

How many grams is 1 cup of dark chocolate chips?

One cup of dark chocolate chips weighs 170 grams, spooned and levelled, according to King Arthur Baking. That is the figure to use for recipe conversion and scaling. Half a cup is 85 grams, a quarter cup is about 43 grams, and a tablespoon is about 11 grams. Mini chips pack slightly more densely and may weigh a few grams more per cup, so verify with a scale when it matters.

How many cups is 200 grams of dark chocolate chips?

Two hundred grams of dark chocolate chips is about 1 cup plus 3 tablespoons — more precisely, 1.18 cups. In practice, most bakers would measure 1 cup plus a generous handful, or simply weigh out 200 grams on the scale. If a European recipe calls for 200 grams, do not round it to 1 cup (170 grams), because you would be short by 30 grams — nearly a fifth of a cup of chocolate.

Can I use milk chocolate chips instead of dark chocolate chips?

Yes, cup for cup and gram for gram — milk chocolate chips also weigh 170 grams per cup. The difference is flavour: milk chocolate is sweeter, milder and creamier, while dark chocolate is more intense and slightly bitter. In a cookie, the swap will make the result noticeably sweeter. If you want to keep the sweetness the same, reduce the sugar in the recipe by about a tablespoon per cup of chips swapped.

Why do my chocolate chips sink to the bottom of muffins?

Chips sink when the batter is too thin to hold them, or when the chips are added to a warm batter that thins further. Tossing the chips in a tablespoon of flour before folding them in helps: the flour coating grips the batter and slows the sinking. Chilling the batter for 15 minutes before baking also helps, because a thicker, colder batter sets faster in the oven and traps the chips in place.

Do chocolate chips go bad?

Chocolate chips keep for up to a year in a cool, dry place. They do not go mouldy, but they can bloom — a white coating caused by cocoa butter or sugar rising to the surface after heat or moisture changes. Bloomed chips are safe to eat and fine to bake with; the bloom disappears when the chocolate melts. If the chips smell stale or rancid, or taste of the cupboard they were stored in, replace them.

What is the difference between chocolate chips and chocolate chunks?

Chocolate chips are small, uniform pieces formulated to hold their shape in baking, with less cocoa butter and added stabilisers. Chunks are irregular pieces of bar chocolate that melt more fully and create pools of chocolate in the crumb. Chips weigh 170 grams per cup; chunks vary by size but are close to the same. Use chips when you want distinct pieces, and chunks when you want melted pools.
