There are about 2.7 cups in a pound of dark chocolate — approximately, because the figure depends on how the ingredient is measured. One US cup of dark chocolate weighs 170 g spooned and levelled, so 453.59 g (one pound) divided by 170 g gives about 2.67 cups. That is the short answer, and the rest of this guide explains where the number comes from, how much it moves when the measuring method changes, and how to use it in real recipes — from a weeknight dinner to a freezer full of baking.

Chopped dark chocolate behaves exactly like dark chocolate chips by the cup — about 170 g per cup, about 2.7 cups per pound — because the pieces are the same density and the gaps between them are the same. The difference is not in the numbers but in what you do with it: chopped chocolate melts into a smooth pool, while chips are designed to hold their shape, so the choice changes the recipe even though the weight does not.

Every figure on this page is labelled approximate, and for good reason: cup measurements vary with packing, moisture and the size of the pieces. When a recipe depends on the amount — a cake, a loaf of bread, a jam that has to set — weigh the ingredient on a kitchen scale instead of trusting the cup. The scale is the only measuring tool that does not care how you filled the cup.

The conversion at a glance

One cup of dark chocolate weighs 170 g spooned and levelled. A pound is 453.59 g (16 oz), so the arithmetic is 453.59 ÷ 170 = about 2.67 cups. The table below gives the cup equivalents for the amounts you are most likely to meet, whether you are scaling a recipe up or working out how far a bag or jar will go. All figures are approximate, and all of them use the same 170 g per cup.

Amount Grams Cups (approx.) Tablespoons (approx.)
1/4 lb (4 oz) 113 g 0.7 cups 11 tbsp
1/2 lb (8 oz) 227 g 1.3 cups 21 tbsp
1 lb (16 oz) 454 g 2.7 cups 43 tbsp
2 lb (32 oz) 907 g 5.3 cups 85 tbsp
3 lb (48 oz) 1361 g 8 cups 128 tbsp
5 lb (80 oz) 2268 g 13.3 cups 213 tbsp

A single tablespoon of dark chocolate weighs about 10.6 g, and a teaspoon about 3.5 g — useful when a recipe calls for a spoonful rather than a cup. And because a kilogram is 1,000 g, the same density gives about 5.9 cups per kilogram: the two conversions are the same arithmetic with the same 170 g per cup, just with a different starting weight.

Worked examples

A chocolate ganache for a celebration cake

Ganache is the recipe where chopped chocolate earns its keep. A ganache for a 9-inch cake needs about 2 cups of chopped dark chocolate, about 340 g, plus an equal weight of warm cream. A pound gives about 2.7 cups, so one bar-and-a-half covers the ganache with a little left for decorating. Chop the chocolate fine and even: uneven pieces melt unevenly, and the ganache turns grainy. A cup of finely chopped chocolate also packs slightly tighter than a cup of chunks, so weigh it — 340 g is 2 cups.

A tray of brownies with melted chocolate

Brownies made with melted chocolate instead of cocoa have a fudgier crumb, and they need a lot of it: a tray of 16 brownies takes about 1.5 cups of chopped dark chocolate, about 255 g, melted with the butter. A pound covers one tray with about 1.2 cups spare — enough for a second half-tray or a batch of chocolate pots. Melt the chocolate gently in a bowl over simmering water and never let the bowl touch the water, or the chocolate seizes into a grainy lump.

Chocolate bark for gifts

Chocolate bark is the simplest use for a pound of dark chocolate. Melt 2 cups (about 340 g) and spread it on a lined tray, scatter nuts and dried fruit over the top, and let it set. A pound makes about 2.7 cups, so one batch of bark uses three-quarters of a pound and leaves about two-thirds of a cup for a second small tray. Tempering is optional for bark eaten at home — untempered bark tastes identical, it just melts faster on the fingers.

How the figure is measured

The headline figure comes from the CookScale ingredient table, which lists dark chocolate at 170 g per US cup (236.6 ml), spooned and levelled, sourced from King Arthur Baking with high confidence. Chopped dark chocolate bars, for melting or folding into batters. The table's uses for dark chocolate are: Ganache, brownies, fondue and baking.

The method matters more than most people realise. Spooned and levelled is the standard for this ingredient, and a different method gives a different weight: scooping instead of spooning compresses dry ingredients and can add 10–20% to the weight of a cup, while packing a sticky ingredient can add even more. That is why this guide states the method alongside every figure, and why the headline number is always labelled approximate. If you measure differently from the stated method, expect a different result — and if the recipe matters, weigh the ingredient instead.

One practical consequence: never convert in the wrong direction by accident. To go from cups to grams, multiply the cups by 170. To go from grams to cups, divide the grams by 170. To go from pounds to cups, divide the grams (453.59 per pound) by 170. Keep the 170 g figure in mind and the rest is simple division — but always check the result against a scale when the bake depends on it.

Practical guidance

The mistake is measuring chopped chocolate before chopping it. A cup of chocolate broken into large chunks leaves big air gaps and weighs far less than a cup of finely chopped chocolate — you can be short by a quarter without realising. Chop first, then measure, and remember that the finer the chop, the tighter the pack. For ganache and brownies, where the chocolate is melted anyway, weighing is always better: 170 g is one cup.

Storage: Cool, dry place, up to 1 year. Weighing the ingredient before you store it, and writing the weight on the container, saves a conversion later: a tub labelled '450 g' tells you instantly that it holds about 2.7 cups, without any measuring at all.

When you do not have a scale: use the cup, but use it carefully. Spoon the ingredient into a dry measuring cup — never scoop from the bag — and level the top with the back of a knife without tapping or shaking the cup. For sticky or wet ingredients, use a liquid measuring jug and read the level at eye height, or lightly oil the cup so the ingredient releases cleanly. Accept that the result will be approximate, and if the recipe is a cake, a loaf or a jam, borrow a scale: it is the single most useful tool in baking, and it costs less than a bag of the flour it measures.

Frequently asked questions

How many cups of chopped chocolate are in a 100 g bar?

A 100 g bar of dark chocolate, chopped, is about 0.6 cups — a little over half a cup. Most recipes need more than one bar: a ganache for a 9-inch cake needs about 340 g, which is three and a half 100 g bars. Buy chocolate by weight for baking and weigh it out; counting bars is expensive and imprecise.

Is chopped chocolate the same as chocolate chips?

By weight, yes — both are about 170 g per cup and 2.7 cups per pound. By behaviour, no. Chocolate chips contain stabilisers that help them hold their shape in the oven, while chopped chocolate melts fully and flows. Use chips when you want visible pieces in cookies and muffins, and chopped chocolate when you want it to melt into brownies, ganache and sauces.

What percentage of dark chocolate should I use for baking?

For most baking, 60–70% cocoa solids is the sweet spot: dark enough to taste properly chocolatey, sweet enough not to need extra sugar. Above 70% the chocolate turns bitter and the recipe's sugar balance suffers; below 50% it behaves more like milk chocolate and melts too readily. The weight per cup does not change with the percentage, so the conversion on this page holds for any dark chocolate.

Should I weigh dark chocolate or measure it in cups?

Weigh it whenever the recipe matters. One cup of dark chocolate weighs 170 g spooned and levelled, but that figure assumes the stated method — and in practice, cups vary by 10–20% depending on how they are filled. A kitchen scale removes that variation entirely: 170 g is one cup, every time, regardless of who is measuring. Cups are fine for soups, salads and smoothies, where a little more or less makes no difference. For baking, jam, bread and anything where the ratio of ingredients decides the outcome, the scale is the right tool.

How accurate is the about 2.7 cups figure?

It is accurate to about plus or minus a quarter of a cup per pound, which is roughly the variation you get from different measuring methods and different batches of the ingredient. The figure is calculated from a single sourced density — 170 g per cup from King Arthur Baking, high confidence — and the arithmetic is exact: 453.59 ÷ 170 = 2.67 cups. The uncertainty is not in the maths but in the cup itself: a scooped cup weighs more than a spooned cup, and a packed cup weighs more than a loose one. Treat 2.7 cups as a planning figure and verify with a scale when it matters.
