Weight or fluid ounces?
Owner's reply
Hi ecrivezmaria, chocolate is a solid so it's measured as ounces by weight, not by liquid. So the measurement is weight ounces. Four ounces of chocolate is roughly a commercial bar of high quality chocolate. I don't recommend using chocolate chips in baking unless they're specifically called for. This is because chocolate chips are usually inferior quality compared to the higher quality chocolate available for baking and in bar form.
If you absolutely had to use chocolate chips, 4 ounces is 3/4 cup. Good luck!
