White chocolate chips

One US cup of white chocolate chips weighs 170 grams. Going the other way, 100 grams is about 0.59 cups.

Also called white chocolate morsels, white baking chips, candies, white chocolate, white chocolate baking chips.

Two sources agree exactly. USDA FoodData Central publishes Candies, white chocolate (SR Legacy) at 1 cup chips = 170 g (derived from the record's cup-portion calorie data of 916.3 kcal per cup divided by the per-100g calorie value of 540 kcal, yielding 169.7 g and rounding to 170). King Arthur's Ingredient Weight Chart lists 'White Chocolate Chips' at 1 cup = 170 g exactly. Both sources land at a density of 0.7186 g/mL, so this entry publishes 170 g per cup and names both sources. Neither source names a specific filling method.

The exact agreement is notable given that white chocolate composition varies across manufacturers. FDA regulations require white chocolate to meet minimum content of cocoa butter, milk solids, and milk fat, with a maximum sweetener share, but commercial brands span the range from just-legal to premium high-cocoa-butter formulations. Despite this compositional variability, chip-form density stays remarkably stable because chip shape (typically 5 to 7 mm teardrops) dominates the apparent density calculation over the small variations in intrinsic material density. All chocolate chip products of this size and shape pack at similar cup weights regardless of chocolate type.

King Arthur's chart reflects this pattern by publishing 170 g per cup uniformly for regular chocolate chips, chocolate chunks, chopped chocolate, and white chocolate chips, with mini chips slightly higher at 177 g per cup due to their smaller size filling gaps more efficiently. USDA confirms the 170 g figure for white chocolate specifically. The chocolate family sits at approximately 0.72 g/mL apparent density essentially independent of composition or color, controlled by chip geometry rather than by intrinsic material density.

White chocolate itself is a distinct product from other chocolate types in composition but not in physical packing behavior. It contains no cocoa solids at all, only cocoa butter (the fat pressed from cocoa beans), milk solids, sugar, and often small amounts of vanilla and lecithin. This makes white chocolate technically not chocolate under some European regulations. Its lighter color comes from the absence of the dark cocoa solids, and its distinctive sweet-vanilla flavor comes from the milk-fat/sugar combination without the chocolate liquor bitterness. Baking properties differ from regular chocolate primarily in melting behavior (white chocolate seizes more easily and browns faster) and in acid interaction (white chocolate lacks the buffering capacity of cocoa solids), but these differences do not affect dry-weight cup measurements.

Product variants: white baking chips labeled 'white chips' but lacking the required cocoa butter are technically not white chocolate. These use vegetable oil (typically palm kernel oil) as the fat and are more accurately called 'confectionery coating' or 'compound chocolate' chips. They pack at similar cup weights due to shared chip geometry but have different melting and mouthfeel properties. This entry publishes the density for true white chocolate chips; substitution with confectionery-coating white chips will not affect gram-based recipe conversions but may affect baking results.

White chocolate chips are placed in the sugar category alongside the existing chocolate chips entry on this site. The category rule tracks physical packing behavior rather than chemistry or ingredient family: small firm particles that pack like granulated sugar sit in the sugar category, whether they are actually sugar (granulated, brown), salt crystals (kosher, table), small dried fruit (raisins, currants), or chocolate chip forms. The 10 percent category tolerance applies here, and the exact observed agreement between sources sits well inside it.

No standards body publishes a bulk density for white chocolate chips. FDA regulations govern white chocolate composition but not physical packaging density. Codex Alimentarius does not publish a chip-density standard. Two independent authoritative sources agree exactly, so this entry is held at medium confidence. A third independent source, such as a professional culinary reference or a producer's laboratory measurement, matching within tolerance would move it to high confidence.
