You can use chocolate chips instead of dark chocolate at a ratio of 1:1 by weight — the same weight of chips as the chocolate called for. That last part matters: chips and chocolate bars have different densities, so a cup of chips does not weigh the same as a cup of chopped chocolate. Weigh them, and the swap is straightforward. Chocolate chips are designed to hold their shape in cookies, because they contain stabilisers that stop them from melting fully — which is exactly why they are a poor substitute in a recipe where the chocolate must melt smoothly. In a cookie or a muffin, where the chocolate stays in chips, the swap is perfect. In a ganache or a sauce, where the chocolate must melt, it is a problem.

The ratio, in a table

The ratio is 1:1 by weight. Chocolate swaps by weight, not volume; cocoa powder needs added fat to replace solid chocolate. The table below converts the amounts you are most likely to meet.

By weight, one cup of dark chocolate weighs about 170 grams (King Arthur Baking, spooned and levelled). No cup weight is published in our ingredient data for chocolate chips, so measure the substitute by volume rather than guessing a weight for it. All cup weights are approximate — densities vary by brand, by how the ingredient is packed, and by moisture — so verify with a kitchen scale where weighing matters, especially in baking.

Worked examples

Chocolate chip cookies that were always meant to have chips

A cookie recipe calls for 8 ounces (227 g) of chopped dark chocolate, folded into the dough. Use 8 ounces of dark chocolate chips instead, weighed, and fold them in exactly the same way. The cookies will be identical to the original — in fact, they will be better, because the chips are designed to hold their shape and give you distinct pools of chocolate rather than streaks. The stabilisers in the chips are an advantage here, not a drawback. Bake at the same temperature and time. This is the recipe where the swap is not a substitution but the correct ingredient.

Muffins with even chocolate distribution

A muffin recipe asks for 4 ounces (113 g) of chopped dark chocolate folded into the batter. Replace it with 4 ounces of chocolate chips, weighed, and fold them in exactly the same way. The chips will distribute more evenly through the muffins than chopped chocolate, because they are uniform in size, and they will hold their shape during baking so each muffin has distinct chocolate pieces. The muffins will be just as chocolatey as the original. Bake as usual. The result is a muffin with a more even chocolate distribution — a small improvement, but a real one.

A chocolate-studded banana bread

A banana bread recipe calls for 4 ounces (113 g) of chopped dark chocolate. Use 4 ounces of chocolate chips instead, weighed, and fold them into the batter with the bananas. The chips will hold their shape in the bread, giving you distinct chocolate pieces in every slice, while chopped chocolate would have melted into streaks. The bread will be just as moist and chocolatey as the original. Bake at the same temperature and time, and check with a skewer — the chips can make the skewer look wet even when the bread is done, so test in a spot without a chip. The result is a banana bread with a better chocolate distribution.

What changes in the result

Two things change when you use chocolate chips instead of dark chocolate, and both come from the stabilisers. First, the melt: chocolate chips contain stabilisers that stop them from melting fully, so they hold their shape in a baked good — which is wonderful in a cookie or a muffin, and a problem in a ganache or a sauce, where the chocolate must melt smoothly. Second, the weight: a cup of chips does not weigh the same as a cup of chopped chocolate, because the chips do not pack together as tightly, so you must weigh the chips rather than measuring by volume. The flavour is the same family — dark, rich, chocolatey — though chips are often slightly sweeter than a dark chocolate bar. In a recipe where the chocolate stays in pieces, the swap is perfect. In a recipe where the chocolate must melt, it is the wrong choice.

When not to substitute

Do not use chocolate chips where the recipe needs melted chocolate — the stabilisers stop them melting smoothly. Do not use chocolate chips where the recipe needs melted chocolate — the stabilisers in the chips stop them from melting smoothly, and a ganache or a sauce made with chips will be grainy and lumpy. Do not use them in a tempered chocolate decoration, where the chocolate must set hard and shiny. Do not measure the chips by volume: weigh them, because a cup of chips weighs less than a cup of chopped chocolate. And do not use milk chocolate chips in a recipe that calls for dark chocolate without adjusting the sugar — milk chocolate chips are much sweeter, and the result will be too sweet.

Practical guidance

Weigh the chocolate chips rather than measuring by volume — a cup of chips does not weigh the same as a cup of chopped chocolate, and the 1:1 ratio is by weight. Use dark chocolate chips for the closest flavour to a dark chocolate bar. In a cookie or a muffin, fold the chips in at the same stage the chopped chocolate would go in. In a recipe where the chocolate must melt, do not use chips — use a chocolate bar, or cocoa powder and butter. Store chocolate chips in a cool, dry place, and use them within a few months — they can develop a white bloom if stored badly, though the bloom is harmless. All amounts here are approximate, and the ratio is by weight: 1 ounce (28 g) of chips per 1 ounce of chocolate.

Frequently asked questions

How much chocolate chips do I use instead of dark chocolate?

Use the same weight: 1 ounce of chocolate chips for 1 ounce of dark chocolate. Weigh the chips — do not measure by volume, because a cup of chips weighs less than a cup of chopped chocolate.

Can I use chocolate chips instead of dark chocolate in cookies?

Yes, and they are the better choice. Chocolate chips are designed to hold their shape in cookies, giving you distinct pools of chocolate. Fold them in exactly as you would chopped chocolate.

Can I melt chocolate chips for ganache?

Not well. Chocolate chips contain stabilisers that stop them from melting smoothly, so a ganache made with chips will be grainy. For ganache, use a chocolate bar — or cocoa powder and butter.

Do chocolate chips taste the same as dark chocolate?

Almost. Dark chocolate chips taste very similar to a dark chocolate bar, though they are often slightly sweeter. The flavour difference is small in a baked good.

Can I use milk chocolate chips instead of dark chocolate?

You can, but the result will be much sweeter and softer. Milk chocolate chips have more sugar and less cocoa, so reduce the sugar in the recipe and expect a softer set.
