A practical starting range for chocolate chip cookies in the oven is 10-14 minutes at 175°C. This page is built to answer the cooking-time query fast without burying the useful part under a long recipe story.
Use the clock as guidance only and confirm doneness with a skewer test, texture check, or other reliable visual cue.
The result usually shifts most with cookie size/weight, dough temperature, tray material/dark pan, so treat the range as guidance rather than a guarantee.
