6 oz of chocolate chips is ONE CUP! Everyone who's said that 1 cup is 8 ounces is correct about that fact, but that fact is pertinent only if the chocolate chips are melted to be liquid. The fact that we're talking about chocolate chips and not liquid makes 1 cup of them equal to 6 oz. I guarantee my answer. Source(s): I'm a baker. TJTB · 1 decade ago.
